READ CAREFULLY AND BE WARNED BEFORE ANYTHING:
THIS CAN HARD-BRICK YOUR DEVICE AND I TAKE NO RESPONSIBILITY FOR THAT!
use it only if you must or not at all
you can read this for some details about what bricks are so you understand what you can get into
this is for all Yoga Tab 2 models 830, 1050, 1380 (regardless of the submodel F,L,LC)
it restores(downgrades) your bios firmware from whatever Lollipop version to the original/genuine one from the latest KitKat stock rom released by Lenovo (and all the latest KitKat stock rom's have 150422 in the rom filename, ie April 15, 2015 and nothing not even minor OTA's were released after this date for KitKat, next ones upgraded KitKat to Lollipop)
useful to:
1. those who want to return back to the KitKat stock rom from Lollipop (if you simply flash back the KitKat stock rom files and you are still on Lollipop bios firmware you will softbrick as the Lollipop bios is a x64 version while the KitKat loader/kernel are ia32 so you will get stuck at efi shells, bios screen etc)
2. those who took the Lollipop OTA, succeded, but had in time problems (bricked their device) and cannot flash a Lollipop stock rom as they don't have one (not being released by Lenovo/available yet and at least some 830 and 1380 models are in this situation), so they must flash back KitKat stock rom and after take the OTA to Lollipop (and the KitKat flashing part put's them in the same situation as those from p1.)
3. those who tried to take the Lollipop OTA and had problems and they tried to flash KitKat stock rom and yet they are failing (this could be due to problems in the updating while OTA was applied, yet could be that their bios firmware was updated to Lollipop version)
4. those who want to test stuff (going down/up between versions) ... you name it...
how to use it:
1. first download and extract the corresponding tool for your device (830 and 1050 models share the same bios firmware so they have a common tool), while at this you can watch the little attached recording i made with the tool restoring the bios for my 1380F tab so you know what to expect when you run it. USE THE TOOL THAT MATCHES/CORRESPONDS TO YOUR MODEL, you can hard-brick if for eg you use the 1380 one on a 1050 model (didn't even tried but nothing good can happen)
2. place your tab in the DnX mode: power off (by force if you have to), press and hold both VolUp and VolDown butons, keep them pressed, now press Pwr to start and release Pwr when it turns on/buzz (but keep holding pressed Vol buttons), in a few seconds your screen will display "Fastboot starting..." and it will hold on that, now you can release the Vols (you are in DnX mode). you must get that message, try again the whole sequence until you succed, don't move on until you have that "Fastboot starting..." on your screen.
3. run the tool (you must have the intel drivers installed, if you flashed to your tab at some point you should have them already), follow the messages i think it's quite easy and straightforward, in a few minutes you will be done and having a brand new kKitKat bios firmware on your tab
(3) if while running it hangs on the "Preparing to push files..." message, and your tab starts to the whatever error message you had before it means that you already have a KitKat bios (the tool works only with the Lollipop bios firmware) so you don't need to restore the bios, you can flash stock KitKat rom directly (in this scenario the tool doesn't modify anything on your tab)
4. when it finishes the tool will automatically reboot your tablet, leave it for a few seconds to start (it will most likely go ninto some efi shell, or bios screen whatever your old files were) afterwards turn it off (long press Pwr) and that's it
5. you can now start in DnX mode again and flash your stock KitKat rom (this step is quite known by now so i won't detail it, there's a lot of info on that in other threads), take OTA's, eat candies... whatever you like
i must warn you again, while i tested this tool (i think i moved from KitKat to Lollipop and back at least 20 times and never had any issue with it) you are the only responsible if something bad could happen, this is playing with bios (and any mistake will hard-brick your tab so you will have to send it to a service for fixing). make sure you have enough battery (while i used the tool even when i was with 5% on my battery i would not recommend, i say at least a 30-40%, the process runs only for 2-3 minutes so that should not be an issue). and of course once it started the flashing DO NOT EVEN THINK OF INTERRUPTING! (you could close other software on your PC that maybe can hang your computer while flashing.. you got the point)
Good Luck!
edit: i already have messages about successful bios restoring (as expected no? ) but failing on completing the OTA to Lollipop update after flashing anew the KitKat stock rom. to them and to all of you people who are going to Lollipop from your newly flashed stock KitKat: SET YOUR COUNTRY CODE!!! after you flash back stock kitkaton the first boot input ####6020# in your contacts and a dialog will pop from which you MUST choose a country (no matter which one, preferably yours or a close one), then after the tab reboots for updating the region and comes back to Android check that you have a country code set by entering #### 59930# and it should show the code you chosed. if you take the OTA without a country set you will FAIL! if you failed on your OTA to Lollipop flash anew the stock KitKat rom and set the country code
also do not take an OTA if your device is rooted, always UNROOT first then take the update, and you can root back after or just don't root until you finished the whole Android installing and OTA updates

thank you! i had the boot to bios problem after trying some not-smart things. after spending an hour on the phone with lenovo this morning getting a repair authorization, i printed out the label. i don't need to send in my 1380f now.
your app fixed that and i was able to flash to kitkat and then upgrade to lollipop.

Works perfect! Thanks!

Pentru putin

Mersi Dorin!

My 1050F cannot boot for long time, I posted the problem(http://forum.xda-developers.com/thinkpad-tablet/general/help-1050f-dead-t3188696) but no one answered me. Today I was very excited to find this post and read it carefully, then tried to do it. But just after the sending progress started (the "xx%" progress began)for about 10 seconds, the program "restore-kitkat-bios-830_1050" vanished(Maybe forced teminated by Windows? I ran the "restore-kitkat-bios-830_1050" after a new reboot of Windows). I waited for about 3 minutes, the "restore-kitkat-bios-830_1050" program still didn't appear, and the tab hanging on a normal picture ( I don't remember, probably a recovery stage picture? but I remember the last line is "the result is Okay"). So I had to disconnct the tab from the computer, and powered it off. Then I try to power it on, but sadly find it cannot boot to any screen. In a dark room, I find the backlight of the tab is on when I pressed the power button, but there is no text or picture on it, regardless of whether I press the power button independently, or press the power button together with any volume button(s).
Now the tablet seemingly has changed into a REAL brick (or hardware brick?). How can I rescue it? The only way is to send it to a service?

i've seen the post with the problem you had, now the thing is on a "normal" bricked tablet (meaning soft bricked one) your tab never hangs at the screen to which you're referring to (Powered by Android) it will always move on (to some error message, bios etc). the same tool was used by me and others (including for your 1050F model last one I recall is @Einwood) and never had issues (until now) so imo it's very unlikely that the problem was from the tool (it's task is quite simple and don;t see what could go wrong) something interrupted the flashing process. also you said you tried both lollipop and kiktkat rom flashing and failed and at least one of them should have worked (the roms are flashed using bios dnx as start) so the issues are with your tab hardware most likely.
but all that is irrelevant now... if it doesn't boot at all and you cannot get it to show ANY message at all (white Lenovo logo doesn't show up when you power on nor does it buzz when pwr on) then service is the only solution
@ The Others: please post your tab model too when posting

Thank you so much for such detailed analysis, but I cannot figure out why the hardware has problem. Yes, now it cannot show ANYTHING, white Lenovo logo doesn't show up nor does it buzz when pwr on. Anyway, I think I have no choice except the official repairment now.
I'm trying to find the LENOVO service sites in Canada, but their Canada official site has no such information, on the contrast, its website is full of sale/order/payment information. I think I should re-think about this company.
Thank you again for the reply.

sorry about your issue, yet repairing should not take long, maybe @workdowg can guide you more as it had a similar problem and was solved very fast (6 days if i recall) sending through fedex on lenovo's expenses.

Yes, once i talked to them (about 5 minutes) they emailed me all i needed and i just had to find a local fedex dropoff center. They boxed it and i got it back in 6 days.... this seems to be a common thing for them....

You are my lifesaver and I just can not thank you enough @ionioni
how can you make a file like restore-kitkat-bios-1380.zip ??!! you are such a genius !! :good:
We will never be able to flash it back to KitKat Bios without this zip file !! :crying:
But why don't we need to flash it back to Kitkat Bios on my Samsung Note 3, S5, Note 10.1 (2014 version) and Nexus 9 ?!!
thank you very much for your hard work again and keep up the good work pls

this was on my inbox and it should continue publicly maybe others can benefit

I'm wondering what your flashing to the tablet with your tool, I have a Lenovo S8-50F and lollipop is pretty abysmal on it, so I'm wondering what your flashing to downgrade the bios so I can try it on the S8, since its very very similar to the 830.

you should NOT use the tool unless it is made exactly for your model, or you most likely will hard-brick. moreover Lenovo uses an in-cpu module for digitally checking the authenticity of the firmware you have on your board at pwr on time and even if you have a bios that would work on your model if it is signed with another key it will cause a hard-brick (the measured boot module will refuse to load the IBB in the new bios).
for eg if one writes the 1051 windows variant of bios on the 1050 android one (they are identical in hardware) it hard-bricks (tested).
send me a link to the latest KK stock rom for your device and i will check on it.

That is what happend to me. My loved 1380f is hard-bricked. Only the white lamp is blinking and it doesn't turn on anymore.
Is there a possibility to repair it or can i throw it in the garbage? Please give me an advice. Thank you very much.

not so much you can do, the hardware is fine, it just got the wrong firmware in it... somehow you must rewrite the bios but you cannot do that from the outside (ie by software means) without being able to boot at least in DnX mode. you can check quickly ... if after you PwrOn (well.. after you long press Pwr button as at this moment Powered On of Off are werid concepts ) you don't get NOTHING on your display (ye not even the Lenovo -> Powered by Android white/black logo) than that's it (try maybe to see if somehow DnX didn't got hooked by entering a fastboot devices and see if by some miraccle you don't see your device there)
your device must be opened by a repairing service tech (especially if he is on warranty), you could do it yourself (i did) but you need the appropiate tools and know/how otherwise from a hard-bricked yet recoverable (the hardware is ok) you will transform it into just a paper holder

updated kitkat bios restore tool to version 2 (foolproof version). read the main thread post at the beginning.

Good morning.
Please let me introduce my situation. I use Lenovo Yoga tablet 2 Pro. On 9-th of november I updated Android to 5.0.1. Unfortunately, one of my commercial aps now can not make a connection with external device (no appropriate information about USB connection is appeared).
I am affraid the problem lies on the Android 5.0.1 system. Before that everything had worked perfect.
That is way I decided to downgrade to the Androix 4.x.
I found above treads, but have some doubts.
Is above tool downgrade my system to Android 4.x or do I need to do some additional operations, to get back to the Android 4.x?
In the section - how to use it (point 5) we can read:
5. you can now start in DnX mode again and flash your stock KitKat rom (this step is quite known by now so i won't detail it, there's a lot of info on that in other threads), take OTA's, eat candies... whatever you like

you must:
1. Downgrade the bios using the restoring tool (you mention "Yoga Tab 2 Pro" so you must use the 1380 version), and you must do that so you can flash KitKat stock rom on your tablet (if you try to flash directly, without the bios downgrade it will fail and you will soft-brick your tablet)
2. After restoring the bios, download from here your stock KitKat rom and extract
3. Flash using Intel Phone Flash Tool (open with it the "flash.xml" from the target_bin directory of the extracted archive). the Intel Tool can be found in the tools directory of the same extracted archive.
4. After you finished sotck KitKat flashing, remember to set your contry code (####6020# in Contacts), also it's not necessary to make your settings wifi etc before you set your country code as they will anyway going to be deleted (a factory reset is performed on country code setting operation). if you don't set a country code you will fail when upgrading to Lollipop.
5. Update using the Lollipop OTA or stay on KitKat

Thank you for explanation.
I download system, installed Phone Flash Tool, open it and chose flash.xml, but after connecting my YT2Pro I can not see device specific with "Start to flash" button in the Device list area of the program.
see below screen. Is this screen looks as it should? (ups, unfortunately I can not post images, because I am new user).
One more thing, tablet should be turned off during flashing?
Right now my tablet is connected to the laptop by USB. It is not switched off and charging is in progress (laptop does not see my tablet as an additional disc/device).
Is above status correct?

[Q] SGS Problem That Nobody Can Fix?

The main Samsung Approved Service Center here in Kenya has just given up on my SGS 1900 UK Model Nov 2010, originally 2.1 firmware upgrade via KIES to Froyo 2.21 in March 2011. They have handed it back unfixed after a week. Cant find a problem like this on any forum/google. Can find one that is fixable with the resistor jig, but Samsung dealer says his jigs don't help:
1) Press power, on comes B&W Samsung GT I900 screen, then the mosaic graphic that resolves to the glowing big "S". Then it buzzes feebly. Eventually it goes black but keeps buzzing now and then. Power off works.
If you poke around trying to get it into 3 touch reset, the Menu and Back keys light up and stay lit.
2) 3 Touch reset will not work. Dunno if it ever did as never tried before.
3) Plug into USB charger, it charges fine and shows the charger icon.
4) Plug into KIES and after a lot of attempts, KIES identifies it + firmware and connects. I can see and save my contacts and it displays CONTACTS, INTERNAL SD and CALENDAR folders in KIES. No more
5) ODIN ( which I dunno how 2 use but have) sees the SGS's COM when I plug it to my comp.
6) The dealer claims to have tried to resart/reflash with Samsung jigs. He has handed it back with a "cant fix".
What the heck is going on here? Looks like I have lost a few hundred bucks and have to throw it away.
When did this start? Phone was working perfectly. Suddenly a solid red icon with large white star labelled "Web Page" appeared on home page but no such App was found in SETTINGS>ETC. In any case, "Web Page" just led me to a totally innocuous page I use all the time as a homepage on INTERNET app. A few starts and shutdowns after that ( the battery was getting low so swx'd on and off like 3 times over an hour), it just went into (1) above.
Phone is STOCK, no mods, no reflashes,no rooting etc
Thanks

if odin can 'see' you handset, have you tried flashing the ROM again? find a stock froyo rom from one of the threads here in the general section (click here) or download from samfirmware.com .
Once you have the rom files, kill all the KIES tasks using the task-manager in windows. Get your phone into download mode by pressing volume down+menu button+power button until you get the yellow screen showing the android working. then open odin 1.7 and connect your handset. once odin connects, click on the buttons for PDA,PHONE and CSC in odin and browse to the appropraite file which you've download in the rom. also click on the PIT button, browse to the odin folder and select the 512.pit file. Once this is done, check the main odin window to make sure the check-box next to 're-partition' is checked. click start and it should flash the new firmware for you.
Disclaimer: I do not take responsibility for any harm that may come to your phone during the flashing process. The instuctions above are accurate but are to be performed at your own risk.
flash Darky Rom 10.1 with JVO Modem . Best GPS i´ve ever had, and my GPS was really bad.

@frostygenius
I don´t think that your instrunctions ARE accuarate. You don´t even mention that he has to be in Download mode if he wants to use Odin. Also you advise to connect phone right after opening Odin and than insert the files, but some versions of Odin are known that they malfunctioning if you do this in this order, You should first insert files and set odin and after that plug in your phone.
And if he claims that he is on stock since bought the phone, so maybe he never used it before.
@peterg123
I´m not exactly following what happens to your phone. If I understand correctly the Samsung released defective ROM via KIES and after a week turn it down? But you already updated and now your phone is broken? If yes, I think that Samsung service center should repair your phone or if its serious damage than even replace it.
Is the phone able to boot-up and work properly? Is your recovery mode and/or download mode working? If the download mode (use 3-button combo - VolDown+Home+Power) is working then you can try recover on your own, but be careful, dont do anything before you are sure that you know what you are doing. You can go through this post before start [HOWTO] [REF] [FAQ] [Guides] [Tutorials] Flash/Root/ADB/ROM [MUST READ!].
Also go through the forum or samfirmware.com and find your official version of rom (Eclair 2.1) to be sure that you can anytime revert to this one because of warranty.
EDIT: Also can you please post some photos or video showing what happens to your phone?
Ok, I dunno if this is gonna help but I had a very similar issue when I first got my phone, within a week of owning it.
Points 1-3, exactly what happened mine.
Points 4 & 5 I didn't try, (was fairly new to Android)
Left it in to my local Vodafone shop & within 5 days I had it back in perfect working order, the maintenance report stated faulty hardware, the display module had to be replaced. Maybe worth mentioning to the service guy?

Thanks for the heads-up I forgot to mention those points. I've updated my original post.

Thanks, it is not possible to get into download mode, or I would have done all that. As explained, the phone will not go past the giant "S" logo ( 3rd screen after power on). This problem has happened to many people, worldwide.
As explained the three button default firmware does not work.
The Samsung repair agent claims to have used the 301k resistor method to restart the phone and even that failed. I am not sure if this is true but he said so.. not sure because everybody reports success with this.
ODIN, as I said ( 1.8) recognises the COM connection just as does KIES. The problem is, I am not in download mode so can't reflash if I tried.
I have used the phone for 10 weeks since firmware upgrade from 2.1 to 2.2 during which I had no problems except the occasional process stopped errors.
Hope this help, thanks for trying for me
Yes you are correct, I can't get download mode. The phone has never been reflashed or messed with. It came with 2.1 and using KIES in March I reflashed to 2.2 and it worked perfectly for 10 weeks until it semi-bricked.
There is the Black Screen of eath...then there is the pulsasing S screen of limbo! That's what I have.
The only harwdare clue I have is the SGS blew the fuse in my car charger shortly before "expiring"...yet if connected to USB or other charger, it charges the battery and displays the logo.

..But download mode doesn't display the S logo or even the first Galaxy S 1900 logo...it goes straight in.
Try looking up in the Development section - I'm sure there is a jig method in there and it might be worth trying yourself, you've not got mush to lose now.
If you can get into download mode eventually, search for and flash Ezbase, that will get you onto a rooted firmware and it works EVERY single time for me. Good luck.
@R34L2Pac
Hi, thanks. As posted, the stock UK model SGS 1900 with 2.1 Eclair worked perfect from Nov to March 2011, was firmware upodated by KIES in March 2011 to 2.2.1 Froyo and worked like a dream until it went "semi-bricked" with the "Logo of Limbo" screen ( the pulsating giant S) for no reason.
A week before this, I changed SIMs when I changed countries and for some reason lost all added apps. I had to re-install them and even then, sometimes twice as I got many "android process stopped" errors --- even on some of the Sansung installed ones like Layar. That is the only problem I ever had.
The phone has only had apps from Market and never been modded whatsoever. Many thanks
Hi,
You said that you can see a pulsating S logo, sound to me like your phone is bootlooping. But you didnt mention if you can get at least to recovery(VolUp+Home+Power)? If you can get into recovery, you could try just factory reset your phone from recovery and reboot your system.
Also in the development forum you can find some kernels which can be flashed via recovery (like speedmod K13 for Froyo), so you can try to flash this kernel and after reboot into CWM recovery you could try to connect phone to ADB and type the command "adb reboot download".
I read on the forum that the home-made jig method worked for everyone, so looks like the samsung technician was doing something wrong. It is worth trying to made one a see what it does. Also found this thread, where user cuperus claims that even with charger can be simulated the jig by heating-up your device. So you can also try it, just plug your phone to a charger, let it charge for 1hour and than try use 3-button combo to go to download mode.

Sorry I should have mentioned that it will not get into 3 button recovery mode, that has zero effect or rather, just sends it to the "Logo of Limbo" ( pulsating "S") just as does the power button.
Will maybe try a long charge time and see if that helps! Many thanks
Try en carefully learn hw to use odin coz I gt tha same exact model. I hav flashed mine many tyms en am on 2.3.4 XXJVP. if u do gt into download mode odin will sort u. Regards frm K.poly.

how long have you tried holding down the 'volume down+menu+power' keys? a simple quick press of the three buttons does not work. you have to keep holding them all down for a bit (sometimes upto to 15-20 seconds) for it to go into download mode.
Sorry for the fast answer but I'm at work atm... I think he needs to do the 3 combo button fix on his phone first. I know it's on the forum somewhere... Can anyone check it for him? I lost the 3 combo the first time I updated with Keys from 2.1 to 2.2 and I had to fix it using a program that I can't remember to go on download mode and apply that fix.
Then he can use Odin to flash a stock rom as he needs, plus having 3 combo fixed!
Good luck mate!

Possible fix for your problem
Hi peterg,
I was looking through the general forum and found this post, where user beamzuk1 describes method how he fixed his semibricked phone. Symptoms are the same (not booting, glowing soft-keys, vibrating, no recovery and no download mode). So he used 'adb reboot recovery', I would say that proper command is 'adb reboot download', but you can try both. Also go through guide HOWTO use ADB, which I posted here the link in earlier post.
Hope this will help.
PS: Try follow beamzuk1 step-by-step, because if you start phone earlier than you connect it to pc, adb might not recognize the phone. Also be sure that you have correctly installed drivers and android-sdk before you try this.
These phones come with a 2 year warranty. Why don't you contact Samsung directly yourself - telling them that the local repair centre wouldn't fix/replace it for you. If you did nothing besides what you described, then I would have thought you were entitled to have it fixed or replaced by Samsung.

Also think that Samsung should repair it or replace it.
The fact your repair center has done nothing to fix your phone, in several occasions, now entitles you to brand new replacement or your money refunded in full, contract terminated and expenses paid for your losses incurred as a result of their negligence.
Why not hit them up for the SGS 2.
I had the same issue with my first Galaxy S...wifi stopped working at first, I turned it off then on again but nothing changed. So I rebooted to see if it would correct itself. Bootloops and no 3 button combo (download or recovery)
Sent it off to Samsung through the Carphone Warehouse in the UK. I'd contact a Samsung Service Centre directly if I were you.

Amazon Blu R1 HD [Firmware] [Restore] [Unbrick] [Unroot]

How to Firmware Restore the Amazon Blu R1 HD
With the Help of many of you at XDA we have put together a working scatter file and I have pulled the Firmware from the device so that we can now restore this phone.
View attachment 3826922
STEPS TO RESTORE DEVICE AND BE ABLE TO HAVE ADS AND OTA UPDATES WORKING AGAIN
1. Download SP_Flash_Tool_BLU_R0010UU_V6.4_Firmware.zip
2. Extract the SP_Flash_Tool_BLU_R0010UU_V6.4_Firmware.zip to your desktop. Note 7zip is great to extract files.
3. lauch Flash_tool.exe
4. select scatter-loading and browser to load MT6735_Android_scatter_R1_HD_Amazon.txt
5. click download button to start.
6. now plug your phone into the computer. to boot the device to preloader and start the flash. You can do it two ways: 1. power off the phone and flash will start or 2. From a powered off stat power on the device while plugged into the computer. either way will start the sp flash tool.
7. once the flash is complete you can unplug the device and reboot it with the power button. Congrats you have fully restored your Amazon Blu R1 HD. Bonus you have also enabled bootloader unlocking if you want it.
Tutorial Video with all the steps need to restore.
NOTE: This has been fully tested on the Amazon R1 HD 16GB model but should work on the 8gb also.
You're the man!
Hi, I keep getting this error:

Do you have any idea how to fix it? Thanks.
Dude this doesnt work for me.
When I plug in my phone, a popup from Flash tools comes up saying, "PMT changed for the ROM; it must be downloaded."
Then what?

EDIT - DO NOT USE THE DOWNLOAD+FORMAT MODE EVER ON THE R1, IT WILL RESULT IN A BRICK, IT MAY WORK ON OTHER MTK MODELS, BUT EXPERIENCE HAS SHOWN IT WILL BRICK THE R1 HD!!!! DOWNLOAD ONLY IS THE ONLY SAFE METHOD!!
Occurs if the names or addresses of the blocks in the scatter differ from the table inside the phone (PMT).
Thats not good, i suggest maybe checking the scatter file making sure its not currupt... Or try the following alternate solution....
http://forum.xda-developers.com/r1-hd/how-to/guide-convert-to-prime-rollback-ota-t3432499
This also seems to be a solution,but perhaps more dangerous last ditch effort maybe?? The video is for a different MTK SoC, but from what what im reading it's the same technique across the MTK lineup..
Perform at your own discretion, not responsible for bricked devices....

The format method, i stumbled upon, i just added as a last ditch effort, I'm not sure whats causing the errors to begin with. The scatter addresses all still match the block addresses mapped in the new OTA, so that theory is shot, im not sure what else could be going on.
If SPFT WON'T FLASH
1. Power off your phone.
2. Hold the power and volume up buttons then choose "recovery" from the menu that shows up.
(volume buttons = up/down, power button = ok/select)
3. Now choose power off.
Doing the above makes sure your phone is COMPLETELY shut off, windows can find your phone, and SPFT will be able to flash it.
I believe that, when you use "power off", from within android, it actually puts the phone in some type of suspend or hibernation mode. I say this because you can hit the power button and it will boot very quickly after powering off within android, but from recovery it takes longer to boot. This was the case with mine.
Your only other option is to let the battery completely drain, then try SPFT.
SHOUT OUT TO ALL THE GUYS THAT ROOTED THIS SUCKER AND UNLOCKED IT! GREAT WORK! ???? :good:

I just saw your other thread you started
http://forum.xda-developers.com/r1-hd/how-to/question-restoring-to-factory-default-t3440059
And now I see why you had this error. You have the 8gb version not the 16gb. So this method uses the wrong scatter file for you phone. Please update the forum if you still have the phone and need assistance. There are some commands that you can run in adb to see the partition sizes and then with that the scatter file can be adjusted for your phone
sorry for being off topic here but i really need to know if its possible to unlock more 4g bands , in my contry they don't release the infomation of what bands the providers work so its a guessing game, since i got this phone i purchased the 4g sim card , even with the band 12 update still stuck at 3g , even with proper 4g apn still stuck at 3g wich i came to a conclusion that the 4g bands from the Blu R1 HD are not the same as my providers...in conclusion can it be done ( open up more bands to see wich band will get me the 4g) and if so please explain to me how i can do so please.
This worked for me, but I had to factory reset after because OTA was still detecting root.
Help me!
hello, I do all the steps but remains in the logo and reboots
THIS DOES NOT WORK WITH 8GB/1GB version :'(
Hello,
I just want to unroot my Blu R1, what should I do?
DOA Bricked
Any hope for an R1 which will now not even power up?
This will not work on any of the latest versions. My model is a 2GB/16GB - I was on Coltons root and tried this to go back to stock with my phone now stuck in boot loop.
Do not use this method.

Lenovo Tab 3 8 (TB3-850M) - Hard Bricked

Hi,
It looks my tablet got hardbricked. Apparently, it looks like it was turned off completely automatically, when in sleep mode. When it's powered off now - pressing power button for a while makes nothing. When connected to charger - white LED flash is blinking only and when trying to power on, and there is no "Lenovo" logo at all. I've tried some of "power cycle" tutorials - but no luck. Once, when using power button, tablet was vibrating crazily and screen blinked, but it was shut down after moment.
Sorry, if there is existing similar thread - this tablet is not very popular. If there is any "magic trick" to make it work, I'll be grateful, if now - probably I'll need to flash new firmware. Currently, I'm discharging it completely.
Best regards.

Are you still bricked? There is the firmware flashing method using SP Flash Tool which restores both the 850F & 850M to full factory condition. Let me know if you need the method and I'll get you links to the guides here on XDA.

I've had two 850F devices hard bricked and was able to recover using SP Flash Tool and a stock firmware package. I'll get you the method posted here. But, out of curiosity, how did you hard brick yours?
(The 850F is pretty much an 850M without SIM/data connectivity support. They also have slightly different chipsets, but many of the specs are very similar. So, I know the method will work on both variants of the Tab3 8.

Hey, thanks for you reply! As I'm not owner of the tablet, it's hard to say how it was bricked. It was on stock firmware, it was not rooted and TWRP was not installed. I've helped to configure this tablet, tablet was turned off everyday at 11PM automatically, and powered on manually, by device owner. She said sometimes instead of powering on to Android, it was booting into FASTBOOT mode (green android image). Once, it just failed to boot, without any reaction. I've tried to recover it using Windows machine, when plugging it into computer (no matter, with, or without Vol+ pressed) it was recognized as Unknown device (instead of Qualcomm, or something). I've tried many drivers - but with no luck, device was not recognized. Also, I've tried 2 machines with Win7 & Windows XP. I've managed to reboot device using power key long pressed, but starting from this point device was not recognized at all... When plugged into USB, nothing was happening. Service guy said he was able to make his computer recognize device using some technical cable plugged directly with motherboard, but all methods to flash firmware failed. He said probably EEPROM chip is broken completely and replacing this part is half of device cost. Thing is, this tablet was bought from China - so no guarantee at all. Well, probably she need to buy next tablet from local electronic store...

Yeah, the service guy is full of it without any doubt. Using a modded fastboot cable, like he was likely referring to, will not only fail to push firmware to the eMMC, but will very likely damage or corrupt the partition index. I can't promise my method will work, but I can say with some certainty that it will. Ok, first things firstt: install the latest SP Flash Tool on your Windows PC or laptop. Also, you will need to install the latest vCOM drivers (for the Mediatek chipset). Do you know how to do this or do you need links? I can post a link for unbricking the 850F, which has been reported to work on 850M, but the thread is a bit erratic and non-concise. It will be much easier if you and I do this step by step. Also, you will need a stock firmware package for your 850M (build version is not relevant). Do you have one or do you need a link?
In a nutshell, this method will do an emergency recovery by directly pushing a stock firmware package to the device's eMMC flash memory. Although your PC is not currently recognizing your device, the vCOM drivers/SP Flash Tool, & your volume down button, will force recognition of the Mediatek chipset. Again, I cannot promise this will be successful, but I can say I've not yet seen a single hard bricked Tab 3 that could not be recovered from a hard brick this way.
Step 1 -- install the latest vCom drivers on your Windows (7, 8.1, or 10) PC/laptop. Here is an excellent XDA tutorial that provides sources and detailed instructions. https://forum-xda--developers-com.c...-10-mtk-vcom-usb-drivers-32-64-t3267033/page1 Sorry for the lengthy url.
Step 2 -- install the latest SP Flash Tool on your PC or laptop. Go to this website for download sources; https://spflashtool.com/
Step 3 -- download a stock firmware package for your TB3-850M. This is a link for a solid firmware package, confirmed to work (take note that build version isn't a factor. The SP Flash Tool will push a downgrade, upgrade, or collateral installation {same build version}): https://cloud.mail.ru/public/LHhe/NkpAi7WuL
When you've completed the above 3 steps, let me know and we will go forward with the firmware recovery process. :good:
I have the same issue. I dont know how but i got hard bricked completely. I was flashing rom on it and it got bricked. Now service centre guy is saying that i have to change motherboard altogether. But your post seems convincing. Please let me know the next detailed process.

Lenovo Yoga 2 1050F Bricked

Hello,
A friend give to me his Yoga2 1050F Tab, because it's bricked...
"After a kind of upgrade he said"
So, here's the situation,
Tab is really bricked, stuck on Lenovo Android Screen.
I've tried to factory restore, no success.
I've searched all the web after factory image to flash, I've found 3 of them... But nothing works !!
The 1st one, the only we can still found here, is a factory image from 2015. And the result is, no more lenovo android screen, i'm stuck on a kind of Bios (?) And can't do anything more...
2nd one, (YT2-1050F_S100196_151123_ROW-fastboot), best result, back to an android boot, but stuck on recovery screen, without any possibility to boot...
3rd one (YT2-1050F_S0198_150422_ROW) impossible to flash, it's always failed at "flash easyimage.zip" step.
Other thing, I don't know what xml file I need to use (flash, flash-blankphone, flash-factory ... )
Here, i'm totally lost. Tab is stuck, And I've no idea what can I do next...
Maybe here anyone can help me ?
Many Many thanks !
Hello,
It seem's i got the same problem.
The tablet downloaded an upgrade by it's own.
The tablet rebooted alone and the try to apply the upgrade but never success.
Now i'm booting on a BIOS type screen.
"VALLEYVIEW C0 PLATFORM"
I can access to different options but the tablet is not reconized by my PC anymore.
I can flash anything on it.
If someone have a solution, it would be great !
Hey @NeedaVirus,
Sorry to hear that the device is bricked. Just this past weekend, I've been sifting through all my old resources because a recent OTA (Yep, a 2020 update!) left both me and my partner's 1050F devices in an unbootable state. You can see we're not alone by checking out the thread on the Lenovo forums (https://forums.lenovo.com/t5/Androi...Tablet-2-1050f-system-update-2020/m-p/5007166). Unfortunately a large number of the very helpful resources on xda seem to have been redacted/removed over the past few years, which leaves a few people scratching their heads (I was for a while too).
Basically, the way I've always done this on the 1050F (and what worked yesterday again), is as follows:
1. Install the "IntelAndroidDrvSetup1.10.0". Google will find this easy enough.
2. Install the flash tool. Nowadays, "Intel Platform Flash Tool Lite 5.8.4.0" (might also be called Phone Flash Tool Lite v5.8.4.0 and again google will find this for you) seems to come bundled with all required drivers, so it's a simple process to install.
3. Plug the device in and put it in DNX mode. This mode is achieved by holding vol up + vol down and pressing the power button until the device vibrates. When you feel the buzz, let go of power but hold the other two until you see a "Fastboot starting..." message on a black screen. This is DNX mode.
4. Restore stock KitKat bios using the "restore-kitkat-bios-830-1050-v2" tool. This one might take a little finding and I'm not sure if sharing it here is acceptable any more. Provided the device is plugged in and in DNX mode (and you have the Intel Platform Flash Tool closed too), it's just a matter of running the bios restore tool and following the prompts. Make sure the flash tool is running on your local drive (usually C).
5. Once the bios is pushed, we need to restore the stock KitKat ROM using the platform flash tool.
First we need to set up the Platform Flash Tool, so open that and select "File" -> "Options". Under "Flash options" tick the "Force fastboot sparsing" option and select "500MB" for the size.
6. Now, we want to use the "YT2-1050F_S0198_150422_ROW" image and you'll need to extract it first. It sounds like you already have the right archive file for this, which is good because I'm not sure if a copy still exists here still.
In the Platform Flash Tool, hit "Browse" and the file we're looking for is "target_bin\flash.xml". Select that. (Side note: I suspect that if your device has been updated to Lollipop in the past, you wouldn't have had any luck flashing this rom without rolling the bios back first).
7. Put the device into DNX mode again, and the Platform Flash Tool should see it (a "Baytrail" device is listed).
Now it's just a matter of starting the flash process by clicking the button.
8. Once the device is flashed, you'll need to reboot it (via the device) but wait for the flash process to report 100% first. Hitting the device power button is the way to confirm this reboot btw. It might take a few mins to get into Android here. This is normal.
9. Now, the device will boot into stock KitKat. We need to set the region though:
Open contacts, add new contact (only if you have none, we just need one).
Now, using the contact search, enter ####6020# and you'll be prompted to select your region. The device will reboot and you'll need to set a few things up again.
10. Run all the OTA updates to get right up to date. Just do this via android itself.
Optional: Do any other crazy bootloader unlocks, roots as desired. A lot of the original resources have been removed for these processes, but where there's a will, there's a way.
I'm sure there are other shortcuts to this process too. I think tontonfraguer was able to just flash a newer rom directly to resolve his bootloop, judging by his forum post over on the Lenovo thread. This is just the process I use, any feedback/improvements are most welcome!
Hopefully it helps someone being hit by the recent bootloops.
Cheers
OMG ! OMG ! OMG !!!
Man, you're THE MAN !!!
I've followed all your explanations, and... IT WORKS !!!

Hey @NeedaVirus,
Sorry to hear that the device is bricked. Just this past weekend, I've been sifting through all my old resources because a recent OTA (Yep, a 2020 update!) left both me and my partner's 1050F devices in an unbootable state. You can see we're not alone by checking out the thread on the Lenovo forums (https://forums.lenovo.com/t5/Androi...Tablet-2-1050f-system-update-2020/m-p/5007166). Unfortunately a large number of the very helpful resources on xda seem to have been redacted/removed over the past few years, which leaves a few people scratching their heads (I was for a while too).
Basically, the way I've always done this on the 1050F (and what worked yesterday again), is as follows:
1. Install the "IntelAndroidDrvSetup1.10.0". Google will find this easy enough.
2. Install the flash tool. Nowadays, "Intel Platform Flash Tool Lite 5.8.4.0" (might also be called Phone Flash Tool Lite v5.8.4.0 and again google will find this for you) seems to come bundled with all required drivers, so it's a simple process to install.
3. Plug the device in and put it in DNX mode. This mode is achieved by holding vol up + vol down and pressing the power button until the device vibrates. When you feel the buzz, let go of power but hold the other two until you see a "Fastboot starting..." message on a black screen. This is DNX mode.
4. Restore stock KitKat bios using the "restore-kitkat-bios-830-1050-v2" tool. This one might take a little finding and I'm not sure if sharing it here is acceptable any more. Provided the device is plugged in and in DNX mode (and you have the Intel Platform Flash Tool closed too), it's just a matter of running the bios restore tool and following the prompts.
5. Once the bios is pushed, we need to restore the stock KitKat ROM using the platform flash tool.
First we need to set up the Platform Flash Tool, so open that and select "File" -> "Options". Under "Flash options" tick the "Force fastboot sparsing" option and select "500MB" for the size.
6. Now, we want to use the "YT2-1050F_S0198_150422_ROW" image and you'll need to extract it first. It sounds like you already have the right archive file for this, which is good because I'm not sure if a copy still exists here still.

Managed to sort it out - many thanks for your guide. One thing to note is the Kitkit restore file needs to be in the root of the C drive and also the file for the flash in my case was the flash.xml file
Glad the post helped you guys out and that you were able to get back up and running. If the post was helpful, why not click the 'thank' button under my post
Hi Hi Hiiii
For those who need the famous "restore-kitkat-bios-830-1050-v2"
HERE'S THE LINK (Personal re-upload) : https://drive.google.com/file/d/13vV6fpNAbWWZUk9_fzmJpMAMax2tlyyB/view?usp=sharing
Be aware that you probably need to do this if your OTA updates Fails :
If system update fails do the following:
1. Flash stock firmware
2. Optionally you can wipe user data (I never did that) from DROIDBOOT
3. Go to contacts manager. Create some dummy contact if list is empty.
4. Go to Search / Find Contacts and enter ####6020#. It will ask you to select country code (first two latin letters, ignore Chinese).
5. Select what you want, then reboot.
6. Go to System Update
7. Install OTA update

Thanks - when setting the country code if you get the 'ERROR : could not read factory ota patch from sd card,or the patch is not correct.' then you need to take the easyimage.zip from the extracted rom folder and copy it on the sdcard (on the root of it not in some folder) then try again (with at least 30% battery level).
Guys,
If someone wants to ROOT his tablet, I can write the procedure. (Many try for me before it really works...)
See ya !
hi everyone , i hope someone be able to help me with this , i also just got this tablet as one that does not even turn on , ive played with it a bit and managed to get some writings on the display, then i found this topic here and tried to follow as instructed, nothing happens, and the screen with fastboot starting goes off. any suggestion ?
thank you in advance.

on your screen, attached, at device manager, i can see the driver for intel adb fastboot blabla is not correctly installed, try:
1. restarting windows while holding SHIFT button till it restarts
2. go through advanced restart option and select startup settings
3. when it reboots and offers to select in black-white options 1-8, select wit button F7 the "driver signature.." part
( you are now allowing to installing unsigned drivers )
4. wehn it reboots, INSTALL intel plattform flash tool.exe again and re-install everyting, this time u will see windows pop-ups in red notifiying you installing unsigned extra extra drama drivers, say yes to all of them
5. flash again, using above instructions, make sure to change intel plattform flash tool settings to force flash 500MB
6. go everyting that is instructed above - step by step - through and report, i had exact same problem and solved it remembering the driver-stuffs weirdness on windows, still not a problem at all, just anoying extra steps

Hello,
A friend give to me his Yoga2 1050F Tab, because it's bricked...
"After a kind of upgrade he said"
So, here's the situation,
Tab is really bricked, stuck on Lenovo Android Screen.
I've tried to factory restore, no success.
I've searched all the web after factory image to flash, I've found 3 of them... But nothing works !!
The 1st one, the only we can still found here, is a factory image from 2015. And the result is, no more lenovo android screen, i'm stuck on a kind of Bios (?) And can't do anything more...
2nd one, (YT2-1050F_S100196_151123_ROW-fastboot), best result, back to an android boot, but stuck on recovery screen, without any possibility to boot...
3rd one (YT2-1050F_S0198_150422_ROW) impossible to flash, it's always failed at "flash easyimage.zip" step.
Other thing, I don't know what xml file I need to use (flash, flash-blankphone, flash-factory ... )
Here, i'm totally lost. Tab is stuck, And I've no idea what can I do next...
Maybe here anyone can help me ?
Many Many thanks !

Samsung S10 + bootloop ERASE FAIL: READ ONLY

Samsung S10 + SM-F975F/DS IMEI stating Taiwan (Update: Very contradicting information if the phone is Snapdragon OR Exynos) if it even matters to solve the issue I dont know
Owner of the above since 2019 without issues; USB debugging mode activated in 2019 and never changed since then.
Samsung always updated which I assume the UI 3 Android got updated in January of my vague memory/recollection (honestly never paid attention of what is being updated, only that the phone needs to be on charge while doing ANY update)
Issue: phone in constant bootloop every 4 minutes with top message in red color "ERASE FAIL: READ ONLY" see photo attached
Cause: happened 4 days ago: Watched video stream on chrome browser; phone froze and applied a 10sec. power shut off (never had to do that before, 1st time)
Investigation:
I tried (found out by doing so) to interrupt the bootloop with pressing Power button and same time Volume Down Button in order to restart it and follow the following commands found on the internet as per UI 3 update:
Recovery Mode as followed does nothing:
Hold the Power button of your device till the power menu pops up and select Power Off. = does not apply as in bootloop
Wait for your device to turn off completely. = it does never turn off completely UNLESS I press Power button and same time Volume Down Button und plug into USB C Data cable of which the charging circle with the lightening strike appears without any percentage % of which photo is attached (phone charge can keep up with its bootloop in order to avoid battery drainage as there is no % indication)
Plug-in a USB-C data cable connected to your PC or USB-C earphones in your device. = I start from here whenever the phone restarts every 4 minutes or whenever I do it manually by pressing the buttons as I described in point 2.
Now, check if your device has a Bixby Button (Such as Galaxy S10/Note10):
Without Bixby Button: Press Volume Up + Power Button for a few seconds.
With Bixby Button: Press Volume Up + Bixby Button + Power Button for a few seconds
After the above steps, you will boot into Recovery mode.
Download Mode as followed does nothing: IT DOES WORK NOW you need to be very fast before the phone starts (recovery mode does not work)
Make sure you have a USB cable connected to the computer
Then press and hold the Volume Down and Bixby buttons at the same time
Continue holding these two buttons down while you insert the USB cable that is connected to the PC
Recovery Mode before update instructions as followed does nothing:
Step 1: Start by turning off your Galaxy S10.
Step 2: After it’s powered down, press and hold Volume Up button and Bixby button (this is the button underneath the volume buttons in case you didn’t know).
Step 3: Without letting go of the Volume Up and Bixby buttons, press and hold the Power button.
Step 4: As soon as your device turns on, let go of the Power button.
Step 5: After you see a blue screen, let go of the remaining two buttons. Now you are in Recovery mode.
Download Mode before update instructions as followed does nothing:
Step 1: Turn off your Galaxy S10.
Step 2: When it’s turned off, press and hold the Volume Down button and Bixby button.
Step 3: Without letting go of the two buttons, press and hold the Power button.
Step 4: You will get into Download Mode.
Have tried all the above methods several times the past 4 days.
Have drained the battery in terms of keeping the phone in bootloop resulting in no power.
Unhooked the battery by means of removing the rear panel and unhooking the battery cable for more then 15minutes and repeat the 4 different methods
Unhooked the mainboard from various connections and put together and repeat the 4 different methods
No indications in Windows 10 Device manager
Questions, doubts and thoughts:
Is it possible in this state to access with ADB of a professional in order to perhaps clear the cache, resolve the issue without having access to recovery mode?
Should I simply try to purchase a new battery even though I never had any battery issues?
I am aware that a motherboard change will resolve it to the cheapest way possible but as I like to save the data such as different accounts this is not an option besides the phone is physically in good condition (never went under water or dropped). maybe to unsolder the flash memory onto a new mainboard as recovery mode might be part of the processor where the RAM is saved.
Any way to drain the entire phone further which may resolve the issue without loosing data. Similar in removing a CMOS battery on a PC mainboard and using a jumper.
Willing to pay and currently living in Europe.
UPDATE: Odin firmware performed by skilled professional member of xda forum, but still not working. EMMC issue which needs to be addressed with ISP in order to fix the issue. unfortunately I was told by local professionals that they do not have the tools for it. Therefor I wonder if someone knows someone who knows someone who can be of help. Location is Spain but Europe would also work.
UPDATE2: Got the phone back from technician who has experience with ISP but still same Error remains as to his conclusion that this is not an Exynos phone of which he has not the hardware tool to fix it and probably no one in Europe will have it.
Thank you very much in advance
Sorry... my english not so good...
so the point is whether you can enter recovery or download mode or not ?

Samfw.com_SM-G975F_XSG_G975FXXU9FUBD_fac
I am not sure but that person who helped me remotely may explain better
According to technician its Qualcomm Snapdragon which can only be fixed with the right tools. Not in europe.
I been getting different information and do require some expertise if someone can please help me
any further advice, input or suggestion?
I also Own Samsung S10+.
its showing the same thing.
tried Flashing Via Odin it failed.
Tried to enter Recovery Mode but also failed to enter recovery mode.
OMG. I thought I was the only one in the world. I sent it yesterday to a data recovery technician to see what they will do since according to some insider in order to recover the data they would have to access the phone and fix the boot of which the problem get solved itself since they can not remove the memory chip itself as it would get ruined. They will diagnose the problem first before they do anything. Obviously a mainboard change would be the easiest but thats not an option.
Was your phone also updated to UI Android 3.0?
How did it happen if I may ask?
I wont give up since my phone is physically totally fine.
Update from a data recovery company its communication:
What we tried to do in order to recover your device's data was to load through the phone's bootloader (in Download Mode) a software agent that allows us (in some cases) to transfer the data stored in the data partition. This software agent has been developed by us together with some of our partners and as we are sure you will understand we cannot give you more details about what this particular software does or how it does it, since this information is covered by professional and business secrecy.
In this case the phone's firmware was damaged to a degree that made it impossible for the information to be accessed with this software.
At this moment, we doubt the data could be recovered by any software available now in the market. That's our opinion, but you can of course send it to other companies to see if they can recover it.
Since I am not the only one anymore with the same issue I recommend for people to come forward in order to get help
So far there is a tool needed to reprogram EMMC but I dont know which tool neither do I know where to find that person with this knowledge

I honestly dont know anymore since numerous people said contradicting things.
I am under the impression it is Exynos as of the research of the model SM-G975F/DS
Need to know exactly if it's Snap or not. If it is, then there're 2 options you can try.
1. Ask some one have the same device model as you, do a ROM dump ( you can google for more detail ). Once you got that, I can share with you the tool needed for restore your device from that dump.
2. Try find your device's Factory Images ( similar to Fastboot ROM, but a little different ), and an authenticated prog of your SoC ( this I can share too if you choose this option ) then boot your device into EDL mode by using fastboot2EDL script ( on Git, you can google too ) then use QFIL ( one tool in QPST Tools by Qualcomm ) and force flash the images into the device.
So far as my experience and understanding, there're only these 2 solutions to fix your device ( if it's Snap powered ).
According to the seller: "The phone is Taiwanese version and CPU should be Exynos 9820"
Maybe someone can help me please.. still
If its Exynos powered, then I have no solution for it. Sorry bro!!!

Hi mate, My phone is Snapdragon powered..
My problem is almost similar.. But not exactly.. After almost 2 months I am not able to find a solution.. But after this period of researching and googling about things related to my problem.. I feel now, either any one of the following is the cause of problem:
1. Emmc is stuck or locked in read-only mode `(Can move files from pc , delete already present files anywhere in any directory, but all changes vanish after reboot... all file and directory structure remain intact- moved files from pc gets deleted.. and deleted files which were already present come back after reboot )
2. Corrupted /data and /cache partition, as e2fsck in twrp terminal results shows "filesystem still has errors" and "e2fsck: unable to set superblock flags on /dev/block/mmcblk0p** ) in both these file system (I think they are preventing flashing procedures- Odin stock firmware flashes and twrp custom ROM flashes both are successful, but after reboot no changes can be seen... - Even Recovery.img and boot.img flashes don't seem to work even both are shown successfully flashed in twrp) After reboot current version twrp boots again instead of newly flashed different version recovery.img ... same with boot.img even after running magisk uninstaller zip files.. running uninstall.zip 2nd or 3rd time also shows magisk patched image detected in log which should be removed in 1st iteration itself..
3. Might be magisk is preventing these changes to be made.. or It might be the /System_root creation as mountpoint for system partition which used to be previously /system normally. This might be the superblock creation which not used to be there
My Samsung's twrp and Download Mode seems to be working but no changes made by them even after successful operations by both.
Can you suggest anything? You can look my thread as to get even more detailed overview of what's happening and whatever I'have tried here - https://forum.xda-developers.com/t/...t-not-changing-anything-after-reboot.4462639/
You can see my attachments in my above thread to see my directory structure of system_root and my download mode pictures and odin system ROM flash pictures.

So far as my experience and understanding, there're only these 2 solutions to fix your device ( if it's Snap powered ).
