Hi @Teligen,
There is already an ongoing thread, about this very topic over here... that shows it's current status.
At the moment, we're just about getting there... but it's by no means an easy feat yet....

That twrp is for a different device. I wouldn't flash it unless you have a backup of your boot/recovery or stock firmware for your device

The only difference is that F has no Modem and SIM Slot for mobile Data but it works fine.
I only use it to root the device without actually flashing it.
Just put the twrp image in your ADB Folder on your PC, then run fastboot with the command:
Fastboot boot twrp.img
This uploads twrp on your device and boots it to twrp. You can leave the system recovery untouched and flash supersu for rooting.
The bootloader has to be unlocked of course.

Ok cheers. Appreciate the info. So I'm wrong in assuming the Tb3-850f came with an already unlocked bootloader? Like many lenovo tabs
Edit. Also the yoga yt3-850f is a different device to lenovo tab3 tb3-850f

No, no. You have to unluck it via fatboot as well.
1. Enable Developer Options
2. Enable "OEM unlocking" Option in there
3. Reboot to Bootloader (Restart and hold down Volume down)
4. Run fastboot oem unlock-go
Next, the Android Bot and a process Bar appears on the tablet and does it's thing. Once that's finished the Tablet restarts and enters the initial Android Setup Screen. So it unlocks the bootloader but ALSO performs a factory reset.

Yea I think your referring to the yoga tab 3, not the lenovo tab 3
Lenovo_TB3_850F and Lenovo_YT3_850F

Yes, I have the YogaTab 3 (X50F). But there probably won't be any harm done unlocking the device and booting (not flashing) from the afore mentioned twrp.img.

Here is TWRP recovery and a SuperSU 2.78-SR3 flashable zip for the Lenovo Tab 3 8/TB3-850F.
https://drive.google.com/file/d/0B7-zQU1VihD3ZVF5cEJHUVpNZjg/view?usp=drivesdk
Credit goes to @Hemphiz for his tutorial and files on TWRP + Root for the Lenovo Tab3 8". https://forum.xda-developers.com/android/general/guide-lenovo-tab3-8-tb3-850f-t3559786

Brilliant! Thank you very much. Just got this Tab 3 yesterday and love it. Will love it even more with root+adaway.

It works great. I used adb & fast boot to unlock the bootloader & then boot from twrp image on PC and install SuperSu. Have been using Samsung for a long time but fast boot is much nicer, especially being able to boot a recovery without modifying partitions or filesystems on the device.

(Finally solved) Bricked, can't boot into recovery,system,bootloader. Always bootlogo

I wiped my phone twice and twice install custom always booted about 10-15min.
I cannot understand where is the error, but you can try this method:
1. Install TWRP v3.0.2 (by Xepeleato)
1. Download the stock ROM B584
2. Install stock ROM with TWRP
3. When phone booted to stock B584 install again TWRP v3.0.2 (by Xepeleato)
4. Try install custom B584
Wish you luck!

I accidentaly deleted android

Hi,
Today I wanted to root my phone, so I unlocked the bootloader, installed twrp etc. Then I got an error: unable to mount /cache. I saw on YouTube an tutorial how to fix it, I followed it and... accidentaly deleted the system :/. Now my phone boot only in fastboot (but I can't even flash a recovery via this) and twrp. Can't even get into volume up+volume down+power, it boots into twrp. Any ideas?
P.S. Sorry for my bad English :d

Seems like you bricked your phone. Use this guide https://forum.xda-developers.com/p8lite/general/mega-thread-root-unbricking-updating-t3400994 and look on Chapter 4: Unbricking . Hope this helps

You have to unlock your bootloader first.

You can try to flash firmware with download mode (vol-,vol+ and power button)

It does what it should. Use Power+Volume Down for accessing bootloader.

Nevermind, I installed android the same way as yesterday, but now it worked. Now I have another problem, I think it's recovery problem, it says "E: unable to mount /data" etc. And it shows internal storage 0mb. So should I install another recovery or what?

Any hope in getting root for this model? from my research it seems to be rootable, but I can't find any rom or anything for it, even here in xda.
Any kind of help is greatly appreciated

IT IS NOT THAT MUCH HARD
i found a way to do it
>>First download latest magisk apk
Link - https://www.google.com/url?sa=t&sou...FjAAegQIAxAC&usg=AOvVaw2Xrf3Ndu6oqxqBK9TKilSx
>>Then download stock rom here

Sog1qkyLy9lXieK2vR&ampcf=1&cshid=1621397379367
[Sorry but u cant use latest firmware cuz its not available]
>>Then extract it and get boot.img
>>Patch it using latest magisk manager
Now lets go to install it
U can use pc if u have but if u dont then follow these steps
Share firmware file and patched boot file to other device and install bugajear app on other device [link- https://play.google.com/store/apps/details?id=eu.sisik.hackendebug]
>>Then open ur tab go to settings enable developer option and then enable oem unlocking and usb debugging on it
>>Enable usb debugging on other device also
>> Connect both through otg and then allow permission then reboot ur tab to bootloader [power+volume up button] u can use app also for that
NOW LETS UNLOCK BOOTLOADER FIRST [it will eras ur data take a backup]
>>Open bugajear after u boot into bootloader
>>Go on last option with sign of electricity and press on [<>] bottom right of ur other device
>>Type [fastboot flashing unlock] then run it
>>Choose yes on ur device with volume buttons [ sometime u press right volume button but it doesn't work then try other]
>>It will erase ur device but ur bootloader is now unlocked now just reboot to bootloader again
>> Now type [ fastboot flash boot ] click on embed sign on top right corner and then link ur file and run it
>>Now just extract ur firmware on other device too and get these files
System.img
Vendor.img
And flash them this is really needed or u end up in bootloop
And tada ur all set just reboot ur device and ur rooted
I am also tryibg to get twrp but it will take sometime

My main goal is to use the tablet as an LCD display for my PC sensors.
I need root to auto enable tethering on usb plug.
Device is still rebooting from the flash for now, but I think it should have done the trick for my purpose.

@Aks BRAR SOTHA Did you manage to prevent Android from updating ?
It tries to update and update fails. Then try again and again..
Edit: For my purpose, I can just disable WiFi, and no more update. But this is not the elegant way :/

O-9 and u-7 decode this i cant share straight msg me here on instagram. I used letters according to numbers on qwerty keyboard

I just found this thread and thanks for the instructions. I was able to successfully root my tablet using this method. Of course it kept wanting to update and failed during the process so I thought I would try to get the update patched...
with the device rooted (with the old firmware) allow the update to download
get a shell with `adb shell` and then `su -` (approve the root request on the device)
the zip file is located in `data/data/com.lenovo.ota/fileslenovoota` unzip it and copy boot.img to somewhere the magisk app can find (I used `/sdcard/Download/`)
patch the boot.img with magisk
use adb pull to get the patched img onto your computer
boot into fastboot and flash the original boot.img, system.img, vendor.img from the zip provided above (in the original instructions)
reboot the tablet. The update should now be able to complete
once complete, reboot into fastboot again and flash the updated patched boot.img
reboot and you should be on the latest version and be rooted.
I've also attached the patched boot.img from the update

Well the first rule when unlocking a device is to never lock the device unless it's full stock like you just flashed it. You should be able to hold the 3 buttons together (called a 3 finger salute) and get into fastboot to unlock it again. If it was a hard brick, there would be no life to it at all. As long as it is recognized in fastboot then it's not a brick. Good thing there are binaries lol
