I've seen nothing on the 1050F or any of the Android based tablets (even numbers). The Russian forum has a guide for the Windows tablets (odd numbers). I'm trying to keep up on what they are doing. I'm collecting files to help us later on...

I'm proud to have contributed to this tip section .
Note that this trip works on majority of 5.0x devices.
One question : is there a 830f version with windows, as suggests :
http://shop.lenovo.com/fr/fr/yoga-tablet-2/
It's in french but selecting 8" let me thinl there's a windows 8 version
I'd ne happy to give it a try... after having succesfully rooted my 830, as i'm stuck with the E: error

When downgrading from 5.0 to 4.4 but fails to enter into the UEFI interface, how to return from UEFI interface to the Android interface.
1, if the BIOS settings have changed, please return all changes, so you need to write down what options were changed.
2, long press the power button to shut down, press and hold the volume + and volume - and power on, enter the FastBoot mode, using data cable connection computer.
3, extract droidboot.img and bootx64 from 5.0 OTA update package, this forum post has given the web link of the firmware, please download it.
4, create a folder named “flash” in the desktop, and then put the extract bootx64 and droidboot.img into the folder, and then create a text document, input “CMD” in the text document and then save, Modify text file txt suffix for bat. Turn off all the useless software!
5, open the new text document.bat, then there will be CMD interface, input
fastboot flash osloader bootx64.efi
and then input
fastboot boot droidboot.img
6, Then the tablet into the driodboot interface, and then in accordance with the downgrade tutorial directly degraded. Be sure to remember to delete a little something in the flash-LtoKK-PVT-810.xml:
Code:
<command>
<string>fastboot erase data</string>
<timeout>120000</timeout>
<retry>2</retry>
<description>Erasing 'data' image.</description>
<mandatory>1</mandatory>

<string>fastboot format data</string>
<timeout>120000</timeout>
<retry>2</retry>
<description>Formating 'data' image.</description>
<mandatory>1</mandatory>
</command>
, and then flash flash-LtoKK-PVT-810.xml use flash-LtoKK-PVT-810.xml,
7, when flashed (flash-LtoKK-PVT-810.xml), you will find that the tablet restart card in the logo interface, neglect it and forced shutdown, then press the volume+ and volume- and power to reenter the fastboot mode,
8, and then flash flash.xml, you will return to 4.4.

Thanks Tang1331726 for this detailled tutorial !!
I'm downloading the 1.15GB file over a poor wifi link... but as I understand you are proposing me to downgrade to kitkat.
As I've never rooted my 830F before when in 4.X nor mdified the bios of it, and updated only thru OTA to 5.01 last week, I'm a little confused about what you propose me.
I should use the proposed rooting technique for 5.0

To be clear. This is to fix the bios error when you upgrade to Lollipop and try to downgrade to KitKat? Also this worked on your 830F?

What's the fuss?!

This. I had rooted kitkat on a pal's 830LC. He update to an OTA (lollipop according to him) and got stuck in vicious boot loop. I downloaded YT2-830LC_S0184_150422_ROW and whatever I'd do, flashing system image would fail. Finally, changed force sparcing to 500MB, and suddenly, it's what's all the fuss?!? By the way, Windows 10 x64, used IntelAndroidDrvSetup1.9.0.
Thanks a ton :good:

Thanks Workdowg, and Thanks tang1331726 for your patience.
My english might be incorrect, but as I per my understanding this fix is when you are stuck and only solution is downgrading from KK to LL.
My situation is somewhat different as I've succesfully ugraded, without any glitch, thanks to the timming Tip warnig (this is a gold one, I wonder how many RMA Lenovo will have to deal with !!)
My exact situation :
830-F
Lollipop OTA succesfully installed (5.01 July 10 2015)
Problem occur using SuperSU (2,40, 2,46, 2,49) after successfully booted tethered recovery.
Can you confirm me that I've to do the process described by tang1331726 to fix the E: signature error, and that I'll still be under Lollipop ?
ps: I guess there's noway to get Windows 8 or 10 on my 830F, altough 851F seems very, not to say tottally, hardawre similar.

You are very welcome!
As far as the "E: signature error" please try posting in the Intel tethered recovery thread. Those guys should be able to help. Some people had luck by placing the SuperSU zip on the MicroSD and installing from there. Also try using the another recovery. I use TWRP on my 1050F.
We are trying to get Windows and/or Linux running on these Android based YT2's. Keep looking back here for more info...

yoga 2 1050F can only access BIOS, let's go to RMA?

Hello everybody, I was trying to revert to a 4.x rom because bluetooth tethering was not working... anyway I used Intel Phone Flash Tool and it seems like he failed to flash boot.bin but restarted anyway
SO I only have the Intel BIOS, I can access all the settings, but I cannot start it in Fastboot mode (it just hangs on FastBoot Starting...) or anything that resembles Android.
Still this BIOS seems more a PC to me than a tablet so I am posting here because maybe there is someway to attach an USB OTG (for example) and boot something from there.

@ionioni is working on a safe downgrade path. We did mine but it could be a disaster if not followed correctly. Your other choice is Lenovo repair support. When i bricked mine, it only took 6 days to get it back in my hands. You could also try the steps here... http://forum.xda-developers.com/showpost.php?p=62237383&postcount=5
Sent from my YOGA Tablet 2-1050F

Thank you very much @workdowg, I passed by that thread, just "DNX" mode does not work on my tablet.
So Repair Support it is.
It's very sad such an awesome tablet has so poor ROM that people has to downgrade it...

that is DNX mode!!! that message translates to: i DNX have started and now i am waiting for YOU to give me a (fast)boot image to start... so that message is exactly the message indicating that you ARE in dnx mode.
updated: read this http://forum.xda-developers.com/thinkpad-tablet/general/yoga-tab-2-830-1050-1380-to-kitkat-t3240487
edit:
before anything:
1. download/extract the files attached to this post, now start your tablet (using the Pwr+VolUp+VolDown) to get to that somehow confusing "Fastboot starting..." message = DNX mode (you must get to that message before continuing!)
2. run the extracted tmp-root-1050F-lollipop.exe file (i am assuming you are on the X64 = Lollipop firmware as that screen pictures you attached shows), should do some stuff and in the end if all well will drop you to a root shell (in that post theres a PrtScr for reference), just follow the messages it's pretty easy. should the exe get stuck/not work put your tablet again in DNX mode and try the other file tmp-root-1050F-kitkat.exe. (this means somehow the bios got downgraded partially on your attempt to return to kitkat). this is just a test to see how to move on, it will not fix nor change anything on your tab, after you reboot it will be in the same state as before (that is if you don't do stuff in that root shell of course)
- report back which one worked (gived you a shell)
- also do you want to go back on kitkat or do you want to stay on lollipop? is important to know as the steps are different

Need help for bricked oneplus two

Hi,
I had updated my oneplus two with cyanogenmod 13 successfully. I had been running this for more than 5 months.
Yesterday i had downloaded an update of CM13 and was trying to install the update, the phone just went blank with a black screen so i restarted the phone. Since then the phone is not loading into the OS, when i try restarting the phone the oneplus logo screen just flashes and then the phone just displays black screen or switches off.
I am not able to enter into recovery mode which is the biggest problem i am facing due to which i am not able to even perform other recovery options.
I connect the phone to computer using usb and when i use any command such as adb devices, i dont see any device in the list. i get error: no devices when i use other adb commands.
I tried using QFIL from quallcom, but i get the below error when i click the download button:

Hi md vasi, you can try the methond on the oneplus community search for "unbrick Oneplus 2", choose "[Q&A] The Ultimate OnePlus 2 Guide - Solutions e.t.c.", go to "how to unbrick".

Hope you it will work for you, please follow the procedure step by step and keep me posted if you can unbrick your OP2 and tell me how you did it. Ok?

Yep, the most important is that you find the right driver for Snapdragon 810, i can't recall where i found the link, it took me a while, wait... i got it, i've found the right driver's link on a website named Android brick or something, with the right driver the flash tool from OP2 will recognise your device and flash stock build.
good luck

[GUIDE] Unbrick X82x Le Max 2, Factory Restore, Reset, Qualcomm HS-USB QDLoader 9008

Hi all,
After reading on letv.re that some people managed to brick their devices and were looking for a fix, I started to check more and more about the issue. What happened to some was that the phone would switch itself off and enter into Qualcomm Recovery Mode and would be seen when connected to a computer as “Qualcomm HS-USB QDLoader 9008”. For others, by flashing wrong files the phone would end up in the same state. Luckily a fix had been found, and it was shared by ParasiTe_RemiX.
DISCLAIMER
Given that maybe nothing will happen to your warranty and this is an unbricking tool, there are small chances that your device might get bricked for good, and I feel the need to say that I am not responsible for any damage caused by following these instructions. Any modification that you do to your phone you're doing at your OWN RISK.
Keep in mind that if your phone goes by itself in the QDLoader mode, it’s better to try some combinations below before flashing it using this method:
1) Keep the power button pressed for about 2 minutes, or
2) Keep the power button + Vol up pressed for about 2 minutes, or
3) Keep the power button while connecting the phone to a wall charger, or
4) Bring the phone into a bright light and press the power button (or power button + Vol up) for about 2 minutes, or
5) Keep the phone charging for more than 24 hours and repeat all the steps above.
If nothing works and you are willing to fix it and you’ll give up all your files, then this fix is for you. Or if you have flashed some wrong files and there is no Fastboot, nor Recovery, this is to be followed. Or if you want to reset your phone to a “factory state”, this is the way to go, and by that I mean if you want to check that your fingerprint sensor is working, or you have some other issues, it’s good to revert it this way.
What you will need:
a) A Windows computer
b) FlashOne program - the flashing program for the software
c) QFIL files for X820 (looks like some dev software dating April,2016)
IMPORTANT – YOU WILL LOSE ALL YOUR FILES ON THE PHONE, PHOTOS, MUSIC, APP DATA, INTERNAL STORAGE WILL BE WIPED.
So if your phone is in this Qualcomm Recovery mode, you can just connect it to the computer, and jump to step 3, if not, and you simply want to flash it, start from step 1.
1) To enter Qualcomm Recovery mode, first turn off the phone and go to step 2
2) Keep pressed Vol Up (+) and Vol Down (-) together and connect the phone by USB cable to the computer.
3) You will see that the computer will install drivers for "Qualcomm HS-USB QDLoader 9008".
4) Unzip FlashOne and start "main.exe". Once you've opened the flashtool you'll see "Flash Type". Here select "Qualcomm - flash dead phone".
5) Select your phone - "COM ..." from "Select device" - here should be the same COM ... as it shown in Device Manager under Ports (COM & LPT) > "Qualcomm HS-USB QDLoader 9008 (COM ...)"
6) Select File "LeMax2QFIL.zip" from the folder where it is saved
7) Press "Flash" in the lower part of the window
8) Once completed, disconnect the phone and power it up
9) Go to Settings – Storage format the internal storage.
To exit the Qualcomm Recovery mode, keep the Power Button pressed for about 1 minute or until the phone will vibrate and restart into system.
That's it. More info you will find in FlashOne program, actually it's almost like I've described it here.
You will be reverted to a "dev" version of the phone, somewhere with April build date. Keep in mind that it's EUI 5.6 and the kernel is different than EUI 5.8. Update it to latest EUI with stock recovery and then install the custom recovery of your choice.
Most of the guys install a recovery for 5.6 on EUI 5.8 or vice versa and then they get the blue LED. That's why you should read the instructions for each recovery and make sure you know which one you're flashing.

Hi
First of all I want to thank you for posting this solution. Yesterday I managed to solve it too but it took me a while to find all this info.
Now I have ran into annother problem, I am not able to flash any rom from the stock recovery, it says "file corrupted" every time.
Any solution to this?

Honestly, I did this restoration of the phone about a month ago. I encountered some issues with the stock recovery but I can't remember what I did to fix it. I think I installed 017s at that time, directly from the dev software. Restarting the phone to recovery I think didn't work. I believe you should turn it off and then start it to recovery directly. I remember I wanted to download 015s, 016s, and even I gave up and wanted to install TWRP for 5.6 EUI but the stock recovery at some point worked. Try to turn off the phone (not restart) and then switch on in recovery. And check erase data as well.

OK. Under Windows 10 it works means it installs the phone as Qualcomm HS-USB QDLoader 9008 and its visible in FlashOne program.

the error that I see is as follows:
13: c:\FlashOne1.9\Lemax2QFIL\prog_ufs_firehose_8996_d dr.elf

Hi,
Did you find a fix for this? It seems like you resolved the error somehow. Would you be willing to share how you did that please? I would be extremely grateful. I continue to see the above errors as well.

Reboot phone (long press volume "-"), after power on (long press volume "+" "-" and power) and just one time flash it.

I don't think that you can flash a X910 with X820 files, although I never tried and never heard someone to do so, the results might not be too good.
That error was due to the fact that he was not pressing the buttons properly before connecting to computer. Keep Vol up and Vol down and connect the phone. It should be switched off before.
Good luck!

Thanks very much
How would I switch off a hard bricked device? Every time I connect the device, the device manager shows that it's been connected "Qualcomm ------ 90008" so how would I turn it off , especially if the battery is embedded?

Can you press the power button for at least 1 minute?
If you have it connected and it shows in computer as Qualcomm... 9008, it's ok. Maybe the files are detected as not being for your phone.
If you suddenly found the phone in such way and you didn't flash something that broke it, try to restart it as shown in the op. If not, try to discharge the battery fully that to flash something that it doesn't belong.

Mi A1 QPST Backup file

Hi guys,
Anyone got a full qualcomm backup of their mi A1? I've suffered power failure during Mi Flash and it seems it corrupted the whole memory and altho it's in download mode(I get it to qualcomm 900E and 9008 ports), I think the only solution is full phone factory image backup since if I try with Mi Flash or QPST I get the Sahara error 9 regardless of what programmer (prog_emmc_firehose) I try.

It's ALIVE!.
Just to update that after debugging the whole windows com stack I struck on a wall and it seems that windows 7 and 10 block something there (I manage to get out of the driver to win kernel on debug but then it fails and didn't had any more nerves to deal with and I'm not a windows guy myself).
So the only solution for low lvl writing is to use linux with point boot to EDL. It seems that for mi A1 even if Qualcomm's boot chain is broken (https://blog.quarkslab.com/analysis-of-qualcomm-secure-boot-chains.html) it should fall to EDL in most cases but in our phone (global version at least) it goes to diagnostic mode (not to be confused with Download mode) regardless of drivers in windows - this is hardwired in the chip. So under linux you should fall in to download mode with hardware short of motherboard points to fall in to the correct mode. You should forget about windows as it depends too much on the selected driver (yes you can manually change driver and fu** the whole chain of communication). You need to hardwarely go to Download mode. Don't believe what windows reports.
From there you can use QDL (check documentation on how to install (you'll also need to install gcc (ubuntu - apt get install gcc) https://github.com/96boards/documentation/blob/master/consumer/guides/qdl.md).
Then download a full firmware flash from xiaomi (that's for MiFlash) and use the files in the images folder for the command ( for instance to be more easy copy images folder to qdl folder and:
./qdl --debug --storage emmc --include 'images' 'images/prog_emmc_firehose_8953_ddr.mbn' 'images/rawprogram0.xml' 'images/patch0.xml')
This will fix the first part of the qualcomm bootchain from there you will have access to fastboot and then use all other tutorials concerning fixes from fastboot.
If enough ppl want it I'll write extended tutorial in the other section.

Kindly do an extend tutorial... And tag me please, if you decide to.
Thanks.
