I rooted mine to use an SDCard as some additional RAM but it started acting very flaky. Now I can't update the tablet even though I've unrooted using a couple different methods. I'm stuck without the ability to update my Yoga and I can't figure out how to reliably unroot it.
[Thinkpad Tablet General] Neo0:
You'll have to reflash to whole firmware, including some more partitions as system, data, etc, to be able to update again.

If you own a X50F, search the thread for a firmware :)

Is there any app that can use the circular power led for notifications?
[Thinkpad Tablet General] TheAvatar:
I have an OTA coming through on my rooted 850F that keeps rebooting and obviously failing as I have TWRP installed. Does anyone know where the OTA is downloaded to? I cant seem to find it, want to flash it in TWRP to see if it works.
[Thinkpad Tablet General] chitown835:
In /data/data/com.lenova.ota/app_otapackages, I'm getting the same ota as you..Let me know if it works or not
[Thinkpad Tablet General] Neo0:
It won't work, I guess. This is a zip which patches your current firmware and no full zip. You're rooted which will lead to an error when you're trying to flash it.

(my experiences with X50F)

Found it there, and the above post sums up the experience. I am going to delete the lenovo OTA APK and hope that stops it from rebooting all the time.

EDIT: moved the lenovo OTA APK from /system/priv-app with no ill effects except System Update in settings crashing (expected) and now no constant reboots!
[Thinkpad Tablet General] Yamaha169:
I would freeze "ota updater" with titanium backup ;--)

Also freeze the "security log agent" to get rid of the annoyance of notifications. And freeze any other update services you may find. ;) good luck

Hi Guys,

I got a YT3-850F wifi only. Its the recent version with upgraded RAM. I updated it to Marshmallow (6.0) and then rooted it with loading TWRP through fastboot.

The trouble started this week when there was an OTA available that failed to install. Did not surprise me. So I removed SuperSU and thought it would be fine, but no luck. The tablet was also unstoppable with applying the update again and again. So I downloaded the Android 5.0 image that was also referenced here in this thread and flashed it through TWRP.

My problem now is, that I got no WiFi or Bluetooth. Tried it one more time wiping /data and /system as well, but the result was the same. It would be great to have a Marshmallow image to flash. But all I found was one in the Russian forum which was made with a weird tool and is not flashable through TWRP.

All I wanted is go back stock, update to 6.0 and then 6.01. Root again and thats it :(.

Any ideas or sources for a Marshmallow image?
[Thinkpad Tablet General] linuxholgi:
In my desperation I tried to use the stock recovery to flash the 5.0 firmware image. For mysterious reasons that worked. Maybe somehow related to the fact that the table was on Marshmallow before. Both TWRP (the russian one and the one here in this thread) flashed the image without errors. But WiFi+Bluetooth would remain dead.

Now I am updating my way through... Already applied 4 and I am not yet at Marshmallow.

Trying to flash standard ROM yt3-x50f

Yesterday I successfully reflashed my yt3-x50f tablet with a stock ROM using QcomDloader.exe. Then I updated my system to marshmallow. Today I tried to Kingoroot my tablet, but Kingoroot doesn't like marshmallow so I thought I would reflash back to yesterdays stock ROM.

Today QcomDloader.exe won't work.

Nor wil qfil.exe.

Nor will eMMC_DL_tool for customer ENG V5.2.0R

I have tried with the tablet operating.

I have tried with the tablet in recovery mode.

I have tried with the tablet in fastboot.

I have used different USB cables.

I have tried cursing in English and Aztec.

Near as I can tell, these programs are not detecting the USB port, but that is a guess.

Using Windows 7 on the PC.

Could marshmallow itself be the problem?
[Thinkpad Tablet General] Neo0:
It your tablet's bootloader is unlocked you won't need any program to flash it. Just start in fastboot mode and use "fastboot flash" to install the old rom.

[Thinkpad Tablet General] cuddlydragon:
Thanks, that's sensible advice, and not obvious to a n00b. :)

My problem is now compounded. I am now stuck in a boot loop and I can't interrupt the boot/reboot cyle. I powered down after enabling OEM unlock (whatever it is called), and when I tried to boot to recovery the loop began.

It's still under warranty. I hope it is not my fault!

One other site suggests that rechargint to 100% might fix the prob. Battery was around 60% when the looping started.

Cheers
[Thinkpad Tablet General] Neo0:
You're welcome. I've never heard of the problem you're facing. Are you able to boot into fastboot mode?

Gesendet von meinem ONEPLUS A3003 mit Tapatalk
[Thinkpad Tablet General] cuddlydragon:
No I cannot enter fastboot. If the tablet would actually power down I would certainly try it, but it is cycling as follows

1. The Lenovo logo is on the screen for 1s

2. Screen goes black for 3s

3. Tablet vibrates

4. Go to 1

If I hold down the power button for a very long time with either of the volume control buttons depressed, the looping stops and the screen goes static with the Lenovo logo displayed, not the penguin. Device Manager on the PC then detects the tablet as android phone -adb interface, but from a PC command window "adb devices" shows no devices.

I was hoping by this morning it would have flattened the battery, but it is still cycling after 8 hours. That's a good thing, because one of it's selling points is battery life. LOL
[Thinkpad Tablet General] 5T33Z0:
There's a lot of possible Sources for error here.

1. ADB & Bootloader: in order to use Fastboot on your PC you need to enter the Bootloader and not Recover Mode (Hold Volume DOWN not up and turn on the Table). Prerequisits: installed ADB Drivers, enabled OEM unlock in Dev Options to unlock the Bootloader!

2. I experienced the same behavior when flashing a) a wrong Rom and b) after trying to remove the Google App from the device. Removing it somehow results in the behavior you described above. I think it's somehow related to the Launcher3 App.

3. Possible Solution: Flash Stock Rom using QFIL

- Find the right QPST File for your device (Russian Lenovo Forum has them)

- Install the Qualcomm Flash Image Loader (QFIL) and Drivers (Watch a Tutorial on youtube on how to use it)

- In Order to get QFIL to detect the Device, disconnect USB Cable, turn it off, hold volume down and connect the USB cable so QFIL can open the port for downloading. Use an USB 3 Port so flashing the ROM will take less time

- Incorporate the QPST File into QFIL (select Flat Build) and Hit "Download". CAUTION: this completely wipes your device!

Good Luck!

[Thinkpad Tablet General] popular stranger:
Hello. I'm new to this tablet (Walmart is clearancing them out for 99.00 so why not). I'm literally doing the updates to it as we speak because it came with 5.xx. Currently I'm on the third update. I've read through the thread and I'm trying to root it. It looks like king root was the way to go if I stayed on 5. But since I chose to go to 6 am I correct that currently the only way to root it is do go on the Russian website and download their firmware?

Thanks and apologies if Ive missed something.
[Thinkpad Tablet General] Neo0:
Your only way to root is to open your Bootloader, install TWRP and flash SuperSu. But be aware that this will break OTA.

I didn't tried Magisk. Maybe it won't break OTA as it's systemless...

Gesendet von meinem ONEPLUS A3003 mit Tapatalk
[Thinkpad Tablet General] popular stranger:
I think I'll keep it un-rooted for now. Although if anyone has tried magisk and their tablet lived to tell about it I'd be wiling to try it too
[Thinkpad Tablet General] Yamaha169:
If the download link is broken for the Recovery .. let me know... otherwise ... scroll up, its burried within the last few pages (not more than 5-10.. plus i posted VERY SPECIFIC directions on the entire process to flash...

However ... since recovery is available, gaining root is much easier than it was... flash supersu/root through recovery. (Best way because it patches selinux ... and ... patches the kernel)
[Thinkpad Tablet General] Tushar019:
Hello. I have recently bought the yoga tab 3 8".

I was scrolling through the pages, but I'm not very tech smart so I didn't understand much.

Could someone help me out with rooting, bootloader, unlocking (whatever is necessary, as I said, I'm not very tech savvy) and installing a custom rom (the stock rom is garbage imo) and xposed

PS: I have not updated the tab to Android 6 yet

Thank you.

Edit: still haven't upgraded to Android 6, but what would be the process of rooting if I do?
[Thinkpad Tablet General] Neo0:
Before rooting make sure to have a stock firmware file on your PC because rooting will break OTA updates. You won't be able to install any system updates after rooting.

Gesendet von meinem ONEPLUS A3003 mit Tapatalk
[Thinkpad Tablet General] Tushar019:
And... Where do I get that?

Also, what's the process of rooting?

Should I upgrade to Android 6?
[Thinkpad Tablet General] Tushar019:
So, I've put rooting on the back burner for now, since I got updated the up to date software anyway.

Now the problem is that a lot of my apps are not working properly because "screen overlay detected. To change this permission setting, you first have to turn off the screen overlay from Settings > Apps"

I turned off the screen overlay for everything I could (the bloatware apparently can't be turned off) but nothing changed.

How do I fix this?
[Thinkpad Tablet General] somestuff:

[Thinkpad Tablet General] djrexy:

[Thinkpad Tablet General] Hastaloego:
and ota doesnt work for you ?

---------- Post added at 05:16 PM ---------- Previous post was at 05:15 PM ----------

i tried magisk, worked like a charm
[Thinkpad Tablet General] popular stranger:
I appreciate the feedback. I've using it without root and I don't really like the fact that I'm missing out on all the root pluses. So I will try Magisk. I just have to now figure out a way to put twrp on my device so I can flash magisk. From what I read I have to first unlock the bootloader, download the twrp from the Russian website, and then flash it?

Can this all be done using Fastboot? Is that the best/easiest way to go about this? Also, I'm assuming this w erase everything but I'll still keep my android 6?

Thank you in advance.
[Thinkpad Tablet General] Hastaloego:
hi and yes, adb and fastboot are your tools.

assuming that you installed all necessary drivers and tools you start with

using the developer options to prepare the unlock and activate usb debugging.

then check if all works with "adb devices" at your pc command prompt

then: "adb reboot bootloader"

check again with: "fastboot devices"

and finally "fastboot oem unlock-go"

yes it will erase everything, including your internal storage.

now you can flash twrp with "fastboot flash recovery recovery.img"

you can extract that .img from the sevenmaxs.zip attachement

i know it says X50M but it also works for X50F.

then boot into recovery and flash the magisk-v12.0.zip for root.

reboot and dont forget to install the magiskmanager

in case you also want to use xposed too, maybe for gravitybox, you can install xposed sdk23 by magiskmanager and install the installer from the attachement.
[Thinkpad Tablet General] djrexy:
no i dont have ota update :(

i need any rom for yoga tab 3 10' with android 6
[Thinkpad Tablet General] popular stranger:
thank you for such a detailed response! I however cant seem to get this think to flash the recovery image. Everything until then is fine, i think. My tablet got formatted after "fastboot oem unlock-go". I just cant seem to flash the recovery. it says waiting for device. frustrating. I went to do the steps over and realized after i did the "adb reboot bootloader" that my tablet seemed to freeze with the penguin. It did that my initial time as well. Is that normal?
[Thinkpad Tablet General] Hastaloego:
im uploading what i got from that russian forum. worked for me to get mm.

first thing first, did you allowed bootloader unlock at the developer options ? see attachement.

if not, you get access to it by Settings - About Phone/Tablet - and tap 7 times on "Build number"

go back to settings and you will find the new menu entry "Developer options"

that penguin is the bootloader icon that came with Android 6. you can test your access with "fastboot devices"

unlocking the bootloader with "fastboot oem unlock-go" can took a while, you should see on your pc when its done.

after that try to reboot first with "fastboot reboot".

if reboot was successful you can go back into bootloader the same way as before with "adb reboot bootloader"

if you see that penguin test access again with "fastboot devices"

now you should be able to flash the recovery.img from that Lenovo_YT3-X50M_TWRP-3.0.2.7_by_SevenMaxs.zip file. Ofc you have to unzip it first. :)

with "fastboot flash recovery recovery.img"

again you should see the progress and success message on your pc.

if so you can boot into that recovery by holding power + vol up until you see that lenovo icon
[Thinkpad Tablet General] popular stranger:
thanks. I have done everything but i cannot get it to flash the recovery. Ive extracted it and tried it both in the tools folder where fastboot is in and the desktop. I may not be the sharpest tool in the shed but this should be easier than im making it. here is a copy of my command prompt.

I'm almost regretting going down this rabbit hole but i'm sure it will be worth it once i have root.

that file "recovery.img" doesnt seem to be in your Eric folder.

alternative use this: "fastboot flash recovery path/to/filename.img"

check if "recovery.img" isnt actually "recovery.img.img" - happened to me previously.

i also remember trying to flash recovery.img.zip once without realizing it was zip and not an .img file
[Thinkpad Tablet General] popular stranger:
Thank you so much. I knew it probably was something small. I did did not put the recovery in my Eric folder. Once I did that it was all set.

I'm looking forward to removing some of these unnecessary system apps and all the other goodness from having a rooted device.

Thanks again and I really appreciate you helping me with this.
[Thinkpad Tablet General] Hastaloego:
you are welcome. dont forget to make a nano backup first with the twrp recovery.. once you start removing apps and stuff, the only other way back is a long reinstalling and ota updating.
[Thinkpad Tablet General] chitown835:
I would advise removing any system apps because the tablet will not boot after unless you back up before
[Thinkpad Tablet General] popular stranger:
Oh definitely. I learned me lesson a long time ago to always make a nano backup first. I always keep one copy on my device and a copy on my pc. It's definitely a headache if you don't make a backup.

I know that some system apps are needed but I also have had a galaxy phone since the s2 and I realize that sometimes manufacturers put a bunch of things on there that you don't really need or want. I also like an older version of youtube that has the widget and plays with the screen off so I need to uninstall the youtube that comes with the system.

I really appreciate the feedback on here. This tablet definitely isn't powerful but the battery life is amazing and it does exactly what I bought it for. Absolutely no regrets, especially now that I have root.
[Thinkpad Tablet General] Hastaloego:
true, there is always lot of bloatware. i just remember deleting some lenovo app, ending with permanent UI FC. had to boot into recovery and use twrp file manager to delete the other lenovo stuff too to fix it.
[Thinkpad Tablet General] AimiFox:
Hi, having a bit of trouble keeping root, encryption and twrp working happily together.

I have a YT3-X50F, I got sick of OTA updates not working so updated using the Russian files. All worked as it should have.

I flashed TWRP from the RU lenovo site, encrypted the tablet (as it wouldn't encrypt while rooted) and attempted to re-root. TWRP wont load the encrypted partition no matter what I do.. it sticks at "Trying decryption".

(I am using magisk for root)

Any ideas? I don't really want to be running around with an unencrypted device.

Does anyone know if the "TWRP for Lenovo Yoga Tab 3 Plus Wifi" works on the ordinary Yoga 3 version?
[Thinkpad Tablet General] Hastaloego:
I'm using the twrp from #501 . why don't you just test the pro version ? it won't brick your device and you can flash the old twrp anytime using fastboot.

Before I try that, I have the latest update, of course the OTA updates and Smart assistant do not work (Thank you lenovo, according to the logs apparently it has a file missing and I pulled the offending plugin from the server, OnekeyUpdate_signed_rdv2.apk is missing, the update cannot proceed without it)

So I downloaded the update manually, but of course I cannot apply it through TWRP.

Can I flash recovery.img.p from a recent update zip over twrp and apply the update?

Basically, what is the easiest way to apply the update?

(It is just the latest update, not a big one YT3-X50F_S000118_170317_ROW_TO_YT3-X50F_S000120_170616_ROW_WC7EE60B67)

There's a new OTA update available. If you rooted your YogaTab 3 make sure to disable/freeze the system update app. I used SD Main to freeze the app. Otherwise you enter a nasty loop of downloading, restarting, failing the update, restarts, redownloading the update, restart, update fail, restart, download. etc.

In order to get the updateworking you have to reflash the untouched QPST File, let the update install and then you can unlock the bootloader again, run twrp and flash supersu again.

I will write a step by step guide later.

Also does xposed for magisk work without issue?

And I assume there's still no custom roms for the x50f version?

Thanks in advance guys
[Thinkpad Tablet General] Neo0:
After seeing some slowdowns on my tab using root/xposed I keep it stock now. For me it's not worth it to loose OTA capability as I'm not using the tablet that much.

Nevertheless: You'll have to try your preferred setup. Keep a copy of a stock firmware package in case you mess up the tablet.

To downgrade you can flash a ROM in fastboot mode. This will wipe all your data. After that you can stay on an early version or update till your desired firmware.
