[OTA] Yoga Tablet 2 830F - Android 5.0.1 - Lollipop ota update 2 - Thinkpad Tablet General

Lenovo Yoga Tablet 2 830F - Android 5.0.1 - Lollipop ota update 2 from Lenovo (20/7/15)
Filename: YT2-830F_USR_S000195_1504220230_WW21_ROW_TO_YT2-830F_USR_S100067_1507101258_WW52_ROW.zip

INFO !!!
My first update OverTheAir with this file was a fail. Only black screen after update and reboot.
(I think because i did not change the country code after flashing KitKat a few weeks ago)
(If the update stuck at 100% in recovery you also have to reflash KitKat ROM)
So i flashed original 830F KitKat ROM via "PhoneFlashTool" with this ROM / Tutorial:

http://www.android-hilfe.de/thema/tutorial-wie-installiere-ich-das-kommende-update-wenn-es-nicht-funktioniert-fuer-alle-varianten.697884/
Changed the "Country Code Setting" via ContactApp ####6020# to "de" (select your language).
And do not update any app like Chrome etc. when it reboots again after.
Then download and start the Lollipop 5.0.1 Update.
Lollipop upgrade reboots into recovery and stays 5min. at 100%.
Then reboots into some intel-flash mode and stays for 4min.
After it reboots into Lollipop OS... :cyclops:
INFO 2 !!! (if you installed Lollipop update 1 first and now restoring/flashing of KitKat ROM fails)

I have the same problem, only that I had the first Lollipop version for 1050F with root and then got the new Lollipop update. The Kitkat version fails to flash. But here is what helped: Go to this post http://forum.xda-developers.com/thi...-8-10-13-3-t2930428/post60490907#post60490907
and download the LtoKKxml.7z and copy the files into the kitkat firmware folder and then flash using flash-LtoKK-PVT-810.xml
I had to remove the parts of the XML that erase and format data. Then it worked
After that I could flash KitKat!!

LOLLIPOP ROOT
So easy, follow steps 1-8: http://forum.xda-developers.com/android/development/intel-android-devices-root-temp-cwm-t2975096
I download "IntelAndroid-FBRL-05-16-2015-PTR.7z" and "UPDATE-SuperSU-v2.46.zip" and it worked with Lollipop 5.0.1.
Make sure you have all the Android, Intel, ADB driver stuff installed (for me win7 installed another one at rooting?)
!!! USE OPTION T4 FOR LOLLIPOP ROOT !!!

Yup I got the notice a few mins ago. I also got it many weeks ago when it bricked my yoga 2 8.3
Advice, when it says Updating....100%. Leave it alone. Last time I thought it was done since it said 100% for many many minutes. So i thought it was stuck or bricked. Just let it sit. It will reboot by itself and restart to the next phase.
It will also sit on the Lenovo android screen for quite a while before it goes to Android is upgrading.

Yes, i got problems too!
- It stays for 8min. at 100%. I leave it alone...
- Then 4 chinese Buttons showed up.
- I pressed the first (reboot i think)
- it reboots, it shows the white lenovo text, then black screen with background light on.
- i waited 10min., no change or start into OS.
- then i pressed 15sek power off, light goes off.
- if i power on, again white lenovo text, then black screen with background light on. nothing... ???
i reboot into recovery and wiped cache, nothing.
i think i will make update from SD card again... see if something happend

Update again from SD dont work! it says:
"/system/app/Chrome.apk" has unexpected contents...
E: Error in /sideload/package.zip

SUCCESS, LOLLIPOP IS WORKING!!!
I Have restored original KitKat ROM via "PhoneFlashTool" with this ROMs / Tutorial:
https://cloud.mail.ru/public/Z2US9gd6f2ei/YT2-830F_S0195_150422_ROW.7z
http://www.android-hilfe.de/thema/t...icht-funktioniert-fuer-alle-varianten.697884/
This time i´ve made the "Country Setting" via ContactApp ####6020# to "DE" befor download and upgrade!
And i have aborted the automatic PlayStore updates for Chrome etc...
Lollipop upgrade reboots into recovery and stays 5min. at 100%.
Then reboots into some intel-flash mode and stays for 4min.
After it reboots into Lollipop OS...

So can you boot back into android? Even after you wiped it? If not and you can't do anything, call Lenovo. I think only they can fix it.
If you can get back into android, I would suggest waiting for the System update notice. That's what showed up this morning for me. I didn't have any chinese buttons. I didn't have to touch anything, just wait for a really long time which is unnerving because I don't know status.

I flashed the KitKat Version again, changed country code, and installed the new Lollipop 5.0.1 update again.
This time there are no chinese buttons to press. (i think because changing the country code befor update).
Lollipop is great, the display is much faster while scrolling in chrome etc.

Interesting. I wonder what the difference between the versions of the country codes are. Mine bricked last time it was updated to lollipop. When I got the repair back, it was back to kitkat and I couldn't update until this morning.
Glad to hear you got it fixed. A few of my apps also stopped working and I had to clear the cache to get it working again after the update.

There are some differences in pre-installed apps. I did not changed the country code few weeks ago because there are some apps in german setup i do not want...
**** Edit *****

Added ROOT on top

mine is failing on Lenovo Recovery. It will go to 100% and failed. I had to reboot. FYI, mine is rooted.

You need to flash the stock kk firmware.
http://forum.xda-developers.com/showthread.php?p=61955463
From my LG-G3 running Jasmine8.0/Skydragon Kernel 4.2

Yes, It looks like I cannot just upgrade from rooted KK. I had to go back to stock kk firmware provided in the OP's link and follow step by step instructions using google translate. thanks workdowg and 5m00v3.

anyone missing 5GHz band Wi-Fi support with country code DE? I cannot seem to change the country code once it has been upgraded to Lollipop.

Lollipop does not longer provide the option to manual change band... it will auto connect to 5ghz if possible.
It has nothing to do with country code DE. You can check your connection 2,4/5ghz with the app "wifi band".
My YT2 connects automatic to my 5ghz. And i have 2 networks (2,4 + 5ghz) with same networkname.

Hi,
I have the same problem, black screen after OTA Update, but now, impossible to acces to recovery, dirrectly a black screen after "Lenovo" logo, have you an ideas ?

Okay, I found the solution ! Make the tablet totaly Off, press volume up and volume down, than press power bouton, you directly acces to fastboot mode, and here you can flash with Phone Flash Tool.

Hi,
thanks for the timming TIPs !!
I can't believe LENOVO dosen't take care of this basic things !!
Thanks to you Lollipop is running on my beloved Yoga.
A little tip while we are avaiting 5.1,
Go in Parameter
Activate DEV options : About this tablet, touch 7 times on "Build Version", it will activate the Developper Menu in parameters
Go to Developpers Option (in PArameter)
UNCheck NuPlayer in multimedia.
--> REBOOT your device
It will allow you to avoid Lagging into the UI and apps.
Note that in 5.1 NuPlayer has been replaced by a bugfree version.
Now my last issue is to root the Lenovo...
I tried the rooting method : http://forum.xda-developers.com/android/development/intel-android-devices-root-temp-cwm-t2975096
but aleas I'm stick with an ugly : E: failed to verify whole-file signature
when trying to apply latest SuperSu when in recovery mode...
Tried with stock 2.46 and BETA 2.49.... same result.
Your help is kindly requested to solve this....

Googling ”E: failed to verify whole-file signature" and each one talks about a corrupt download... They are old posts from 2013 or so but they could be right.
Try this version 2.40. You can update in the Play store once your rooted.

Sent from my YOGA Tablet 2-1050F

Thanks for your help.
I tried the 2.40 version triple check the zip file, aleas same error...
Also there are not only corruptions problems related... some are related to CMW version problem and lack of "unsign" option..
Again thanks for the 2.40 link. If you have any suggestion I'm all ears.

There is a new update, to yt2-830f_usr_s100191_1511230623_ww52_row
anyone tried it already?

Looks like it requires going back to stock KitKat again just to update it.
Can't really be bothered trying it.

Is it possible to install a different regions firmware to my S4?

Hey guys quick question before I download and attempt it, I have an Australian i9506 (Cat 4 LTE) but we don't have an official 5.0.1 firmware yet.
Can I just download the Nordic version from http://www.sammobile.com/firmwares/database/GT-I9506/ and install it, or would it brick my phone/radios not work?
Thanks

Hi mate,
Yes you can !! it will not brick it , you may have (or not) problems with the modem as maybe is not the best for your region but you can always flash another...
should not be a problem
BACKUP first , nandroid and your EFS Folder, just in case there is a problem
Just to add to the previous suggestion, use Wanam's EFS Backup Tool rather than Samsung Tool, as it not only backs up the EFS partition but the hidden partitions where the IMEI and the modem are stored.

+1 mate!!
It also depends if your phone is carrier locked.
Thanks for the advice guys I'm giving it a try now, will edit as I go. My phone is not carrier locked (Voda AU don't lock them fortunately but they provide the codes on their website for free to unlock anyway).
So I downloaded Odin3 3.09 and the firmware I9506XXUDOA6_I9506NEEDOA6_NEE (this is the link from sammobile).
I'm following the instructions I found on another site but it's basically put the phone into download mode (home, power and volume down), agree to enter download mode, in Odin for AP select the .tar.md5, make sure Auto Reboot and F. Time Reset are ticked but not Re-Partition or anything else and start.
EDIT 1: The phone rebooted into recovery and updated something, now the phone is booting with a new boot animation. (for those referring to this I was on the latest AU Voda FW, then updated to CM12 5.0.2).
EDIT 2: After the usual nerve-wracking amount of time of first boot the boot logo finally went away and the usual "optimizing apps" message has come up and it's started (235 apps whoa the bloat). Waiting for that but at least it's working to a point where I can recover it. I just realised it's 6:10AM now and I FORGOT TO MAKE A BACK UP. I hope this works but worse case scenario there's a 4.4.2 Vodafone firmware I could flash and try my luck with if this doesn't work out.
EDIT 3: I'm not sure if it's part of the setup process but the word "UP" then a short progress bar appeared on the screen, now I've got only a black screen with a status bar (4G icon is there but no clock). I have rebooted from the power menu, let's see what's going on here.
EDIT 4: Cache wipe from stock recovery didn't work, trying factory reset from stock recovery. I note that the first time I set up the phone it was plugged into the computer with ODIN still running, I don't think it could have interfered but I unplugged the phone this time just in case.
EDIT 5: I'm not sure if it was ODIN or needing to do a factory reset but it's working now, I'm running through the set up. WiFi is working 100%.
Final EDIT: Everything is working 100%, tested the camera, proximity sensor, screen rotation, voice calls, mobile data, wifi and it's all 100%.

Thanks for let in us know.
For any other Aussies out there trying this I'm on day two and everything is working perfectly, getting root is super easy too, just use Odin to flash a custom recovery (Solk's CWM from May 2014 works great), boot into the recovery and install UPDATE-SuperSU-v2.45.zip, exit and when it asks if you want to repair root say yes. Reboot, go to the play store, update to the latest SuperSU and all is well.

LG GPad 7.0 LTE (v410) Firmware Update (?)

Just plugged the Gpad in to charge and this popped up. Hoping it's 5.0.
It's just sitting on 0% for the longest time.
I will update the status when I have something to report.
#fingerscrossed
-----------------------------
Updated on post:
Nothing. False alarm. I don't know how or why my tablet ended up on the update recovery screen because it was already powered on when I plugged it in, but no update.
That mode is only to update via lgflashtools....
My cousin's v410 is dead and I plugged it in to a USB wall charger. Some conductive trash must have been in the plug, I guess, because it rebooted to firmware update mode on me, instantly and from any state. If you see this mode unplug your tablet, hold down power to restart, and try a different cord or blow/clean the trash out of the plug.
Update to Lollipop lg G pad 7.0 lte v410 AT&T if you got a root issue
I had rooted my lg G pad and could not update to lollipop update this is how I got it to work. I removed the SD card and Sim card then I unrooted the tablet and restarted it. I also performed a hard reset from the settings menu. Make sure you unselected the data backup and automatic restore before resetting, now reset tablet. When it restarts just log into the WiFi and nothing else. Now go to settings and go to update center to find the firmware update download it and install it.

Does anyone have any KDZ files?
I had a corrupted Stock ROM on a G Tab 7 Tablet due to applications that were installed by the previous owner; no matter what I did, Addware apps would always install on there own; I mean, even after restoring factory settings via the settings, or via the hardware combinations keys to reset to factory settings, It would reset the device but it would still install all the annoying apps as if they were Factory installed; weird, I had never seen something like this in any device I've worked on.
Anyways, since Factory Reset wouldn't help I had to Flash the Tablet.
I found the V41007h_0.kdz file which I was able to flash using the the LG Flash tool.
But now there is a a watermark in red "userdebug 4.20.17(42001700)" in the Home Screen.
So I'm hoping at the very least I can find a KDZ file to go back to the firmware version that the Tablet had which was V41010d.
Does anyone have any links to point me in the right direction?
If you can't post it in public, please Private message the links.
Thanks in advance for your help.

You've flashed a KDZ that contained a test build. If you follow the steps in my thread here http://forum.xda-developers.com/g-pad-10/general/tutorial-lg-gpad-v410-5-1-to-4-4-t3232150 then you can recover the lost space of your internal SD card and run custom ROMs. Unfortunately I don't think there is currently a way to go back to stock 5.0.2 from this point. If there is, it has not been documented in this form (to my knowledge).
Please post in my thread if you need help with that process.

I could not get it through SIM card because i don't have an AT&T SIM neither i live in the US nor AT&T has any services nearby, so i definitely need a zip file that might be an OTA or something that can be installed via ADB or system recovery. please share somethings for me.

I was trying to update my GPad 7.0 to 5.0.2 or 5.1.0 from 4.4.2 and no OTA updates no matter what I do.
I'm on Android 4.4.2 with software version v41010d. Hardware says LG-V410 in "about tablet" section.
What's the quickest easiest way. I'm concerned that this is an older tablet and isn't updateable or has some update problems so that is the reason for my question. Maybe I'll keep it on 4.4.2 but wanted to run latest Kodi which won't work with anything but 5.0 or greater.

I never saw the OTA captured or a 5.X stock rom posted here, sorry. AT&T is notorious for blocking the release of firmware packages for their branded devices, so you won't find a V410 kdz from LG support either. If you can't get the System Update to work from the Settings menu, you might be stuck as far as stock goes. There wasn't much interest in updating stock in the community here because stock 5.0 patched the vulnerability that let us sign our own boot images. That effectively blocked TWRP and custom roms since the bootloader can't be unlocked. You could try the old take your sim out, reboot and check for the update trick. Some people say that doesn't work, and others swear by it.
There are plenty of 5.X and higher custom rom options, if you want to update the system that way. Tesla, Tipsy, and Validus were all 5.1 roms and they're still on androidfilehost.com. LOS and Candy have been updated up to 7.1. I keep Tesla on my V410 and it works great. All the custom roms rely on being on the 4.4 stock bootloader and radios since the kitkat bootloader was the only one vulnerable to the Bump exploit, so you're in a good place to start from.

I find it strange that there isn't a separate device category on XDA for GPad 7.0. I guess there must be a reason - but it's probably too geeked out for a common humanoid like me to understand.

You aren't the first person to wonder about that. We requested a different forum for the V400/410 early on and it never happened. I don't know why. It does get confusing. You'll find the V400, V410, V480, V700 and probably a few more devices discussed here. A large majority of the development is for the V400/410, though.

That should boot you into TWRP without actually flashing it. If it works, from there you should be able to try to wipe and flash some roms. Sorry, but I'm not convinced it will work in the state your tablet is in. If your device is falling back to fastboot, your laf partition is blank or damaged and very possibly some other partitions are missing or damaged too, and that might prevent TWRP or roms from working right.
If that fails, you can use fastboot to restore the laf partition and hope that brings back download mode so you can try the kdz again:
Code:
fastboot flash laf laf.img
I've restored my laf this way; I actually intentionally nuked laf to enable fastboot. I can provide laf.img if you decide to try this.

S4 DUOS, GT-I9502, can´t finish “Odin updating” even for stock roms

Hi everyone, I´m really pissed about that issue; I´d really appreciate any help and thanks in advance to you all.
Story: I was using Sva´s rom for kitkat, everything normal, then I´ve seen Sasikas´s for lollipop and decided to try it out. I flashed the original firmware and then the custom, both via odin, used them normal as usual. For some reason, I decide to compare the new sva´s, also for lollipop and when I tried to flash, THE ISSUE BEGAN!
Issue: after doing the normal odin process, when the message “complete” shows up and the phone reboots, the bar of updating progress stop about 25% and the phone reboot to the normal mode, but only with a black screen. This is the screen I´m talking about: 3w generacionandroid.com/wp-content/uploads/2014/09/Android_updating.jpg
What I already tried and it didn´t work:
1 – factory reset after the “boot”; I think the problem is that the “system isn´t being write” so …
2 – different roms, both custom and stock; something interesting about this is that the point of the bar that resets the phone varies according to the rom I use, just as follow:
Rom lollipop: at 25% of the bar the system restarts;
Rom kitkat: the bar jumps from 25% to the end and boots the system until Samsung logo. I noticed that the carrier logo sound is cutted in the end.
I can freely install any recovery and enter dl mode.
By the way, the bootloader file must be flashed at pda or bl in odin?
Flash the bootloader file in the BL slot.
about the bootloader...
I´ve installed a bootloader to try the new lollipop in sva´s rom, maybe because of this I can´t flash anymore? I´ve found this info about bootloaders, could someone tell me if I´m thinkg right about it?
"In literal terms, bootloader is code that is executed before any Operating System starts to run. "
This way what I need is a bootloader for kitkat or previous? Where can i find it?
cry for help
almost givin up...
so, happy new year to everyone, I´ll wait until January to check any replies, otherwise selling for parts. ='[.
Shortening: I can enter recovery and dl mode BUT not getting to install roms;
I know I fixed selinux permissions once and installed a bootloader said to be to install a version of lollipop, that´s all new stuff I did.

Yoga Tab 2 830f Is there a soft brick fix?

I've searched but apparently it seems like most of the answers have been deleted or redacted.
My problem...
I was just given a Yoga Tab 2 from my sister who has given up on trying to fix it.
The tab was on 5.01 and rooted when she got a system update. She ran the update but now the tablet freezes during/after the boot animation.
It will go into fastboot but is not recognized by ADB.
She tried to install the original Lollipop firmware through recovery but ended up getting a system 7 error.
This is exactly what I see when in the bootloader screen
FASTBOOT MODE

IFWI VERSION - Blade_21.x64.0005.R00.1504101447 FFD8_X64_R_

E: No valid installer medium found
I know nothing about Lenovo and how they do things but I know that with HTC you have to go back to 100% locked and stock before you can install an OTA. If you do try the OTA usually just won't install but unfortunately this thing seems to be at least soft bricked.
Is there a way for me to maybe roll back? I've read about people going back to KK in order to get the LP OTA but all links to the KK firmware are gone.
Thanks a lot, I appreciate any help I can get...
BTW, She is under warranty but of course she was rooted and is worried that repair will cost her almost as much as she paid for the Tab when they realize and void her warranty.
If its the same as the 1050f try these files.

http://tinyurl.com/zgt7sjo do not bother about the warning with this one, its something to do with its size, just download it.

Thank you. I used the Restore KitKat Bios you posted along with an 830F specific KitKat firmware from the Russian Lenove site. Worked fine after editing the flash.xml file to allow for a larger system.img file.
The tablet is now back from the dead. Unfortunately it gets the 5.0 update but fails in the Lenovo Recovery when trying to flash the OTA. It gets to 100%, stays like that for a bit and then a blue X saying flash failed. After that I'm back to a black screen and have to reflash the kitkat firmware to get up and running again.
I have no idea why the OTA flash constantly fails but I guess I have to do a bit more research and hope I can get her up to date.
Did you set the country code , without setting it updates fail.
Look at this advice from ionioni to me about setting the code

Outstanding!!! I entered the code in contacts and it gave me a menu of different countries to choose from. I Chose US and she rebooted, went into recovery, ran a bit and rebooted into another fresh install which looked completely different. We're talking different wallpaper, and different apps. After that it successfully installed 4 or 5 OTAs and as far as I can tell it is now completely up to date!
Android Version is 5.01
Build is S100250-160119
Kernel Version is 3.10.20-x86_64byt-g9f7fad7
Security patch is dated 2016-02-01
I'll wait a few days before I root and install Xposed just to be 100% certain it's up to date.
Of course my sister will probably ask for it back now.
Either way, THANK YOU VERY MUCH corasman!!! Your help has been invaluable!
I am so pleased it worked for you, ionioni helped me so much and now I am trying to do the same for others.

Software upgrade failed MM

I am unrooted running a stock B180 right now on my PLK-L01 Honor 7 device. I have over the past few months waited for Marshmallow 6.0 Upgrade as it was promised that it would come over OTA the start of this year. Though it hasn't so I decided to manually upgrade the software so I downloaded the latest full version firmware of B320-330 from the hihonor UK website. The software installation goes fine up until 60% then suddenly I get an error message saying "software failed". Why am I getting this error message when the firmware is correct? I am located in Sweden and the closest region to mine is UK so therefore I got on their website and downloaded this firmware. There is only 1 firmware that applies to the Europe region because there is no firmware that's particularly for Sweden itself.
Funny thing is even though I get an error message "software failed" the device still reboots and the Android v.6 works perfectly. If it does not install properly, marshmallow shouldn't even be working! Guys what could be wrong please help! I want to do a clean installation without any error message.

this is normal!
Now you can redo the update process with pressing vol+ & vol- & power button for more than 3 sec.
After than the update process starts again! This time it should be finished with 100%.
Thanks for your reply,
Really? That's strange. This is the first time I am to believe that even after an error message something works just as good. So just after the error message shows up I need to press vol+,- and power button at the same time so it will resume. Didn't know that. Instead what I did was I did a rollback to B300 and then updated to B330 this way I didn't get any error message. Very cumbersome.
If you are on B330 now, you should know this code too: *#*#2846579#*#*
If you enter this code, you will see a new service menu! This you need to manual update in the next future!
To manual update, you have to copy the update.zip into folder "dload" at your ext.sd.
After than, you use menu point 4 to have the possibility to start the update process manuay.
So don't forget this code.
Yes I know that code but honestly it doesn't matter whether you use that code or do a forced upgrade it still results in error message. Yes I did exactly as you are saying even before your message that's how I did it.
A question I have to you. If sometime later I regret and wanna go back to b180 can I do so and still get the marshmallow update OTA? Like going back to the stock b180 software which I had earlier or before I did any manual upgrade at all.

this should be possible. -> Rollback B300 -> reboot -> now you are on B300! -> Update B180 Full rom from the Honor page -> reboot.
If all is going right, you are back on B180.
During the rollback, all datas will be erased! So make a backup at first!!!
See my signature point 1 & 2!!!
BTW: I think there is no difference between the manual or OTA update becaus e it is nearls the same procedure and it has the same file.
Maybe it is possible to extract the B330 update.app with honrorextractor. Than you have to flash most of the extracted files with fastboot.
(Boot; Recovery2; Recovery; System; Data; Modem; Cust; *.img files)
After the next reboot (fingers crossed!) the update procedure should finished without errors.
Yes that's the way I had imagined it to be, doing a rollback to B300 and then downgrade to B180 however will this be the official stock firmware? What is signature point 1 & 2, I don't understand?
Also, where can I get the honorextractor from? Never heard of it besides flashing and fastboot all refers to when the device is rooted and mine is not. I am familiar with these terms as my previous phone was rooted so. I don't understand this boot, recovery, data ,modem, cust part etc its very confusing
