[GUIDE] Root Stock N using jcadduono's Recowvery tool. H830.

Using the following method I was able to successfully ROOT my H830 running stock 20A NOUGAT. With this root method you will get TWRP Recovery and SuperSU. This method WILL wipe your internal storage, so please BACKUP!​
Your warranty is now void. I am not responsible for bricked devices, dead SD cards, or lost photographs.
Please do some research if you have any concerns about root!​
I used jcadduono's method which he describes on the V20 forum [Easy Recowvery ALL CREDITS TO THE AUTHOR. PLEASE GO RATE HIS THREAD AND CLICK THANKS IF THIS WORKS FOR YOU!] https://forum.xda-developers.com/v20/development/h918-recowvery-unlock-v20-root-shell-t3490594​
1. Bootloader Unlock
For this method to work you must have an unlocked bootloader. Despite the fact that I already had an unlocked bootloader, after the upgrade to stock N, jcadduono's script failed to work initially and gave me an error message saying my bootloader was locked. To fix this I had to manually relock and unlock my bootloader one more time. Unlocking/Locking your bootloader will wipe the internal storage of the devices so backup before this step. If you however, already have an unlocked bootloader, feel free to skip this step and go on, although in the end you might have to return to it if you get a "bootloader locked" message in the Recowvery script. If you do skip these steps, don't forget to download the LG Drivers from below.
1. Download and install the latest LG Drivers from HERE
2. Download the minimal adb and fastboot tool from HERE. I recommend the portable version, which you can extract to your desktop.
3. On your phone, go to Developer Options and turn on Enable OEM Unlock.
4. Enter fastboot mode: Turn off your device, press and hold the volume down button, while holding the volume down button connect your phone to your computer by USB, continue holding the volume down button until your device enters into fastboot mode.
5. On your computer go to the folder which you extracted in step 2. Open a command window by holding down SHIFT, right clicking with you mouse inside the folder, and selecting "Open command window here"
6. In the command window type "fastboot oem unlock" to unlock your bootloader, this will erase all of your data.
7. Type "fastboot reboot" to reboot to system.
2. Installing TWRP using Recowvery
Prior to this step I HIGHLY recommend factory resetting your device, if you just unlocked your bootloader, your device was automatically factory reset so you are good to go. Once your phone turns on after a factory reset, I suggest signing into your google account and setting up your phone as if you are going to use it, we will not be factory resetting after this step. However do not download any apps or mess with the settings yet, you can do that later, once your device is successfully rooted.
1. On your computer, download Recowvery from HERE and extract the folder to your desktop.
2. Now on your phone enable USB Debugging in Developer Options.
3. Connect your phone to the computer and make sure File Transfer is chosen in the "Use USB connection for" pop-up.
4. On your computer, download the latest version of TWRP: H830 or H850
5. Rename the downloaded file to "recovery.img" and place it on your phone's internal storage [/storage/emulated/0]
6. On your computer, open the Recowvery folder you extracted in step 1, and click on EasyRecowvery.
7. Once there, type option "5" and "ENTER", in the "Extras and Advanced Tools Menu" disable integrity verification by typing option "7" and "ENTER". Return to the main Menu of Recowvery by typing option "0" and "ENTER"
6. After disabling integrity verification, run the exploit by choosing option "1"
7. Follow the prompts in Recowvery, your phone should reboot about two times in the process.
8. DO NOT Wipe Cache while in TWRP.
8. Once finished, your device should reboot to system and will have TWRP recovery, instead of the stock recovery. The only thing left now is to install SuperSU.
3. Installing SuperSU through TWRP
Although Recowvery does give you an option to install SuperSU through its interface, doing so caused problems in my case. Therefore I recommend manually booting into TWRP and installing SuperSU from there.
1. Download the latest version of SuperSU from HERE and place the .ZIP file on your phone's internal storage.
2. To boot into TWRP, go into the adb and fastboot folder, which I described in the very first steps of this tutorial. There, once again open a command window and type "adb reboot recovery".
3. You should now be in TWRP, there select Install, find the .ZIP file of SuperSU in the file explorer, and install it. DO NOT Wipe Cache after the installation.
4. Reboot to sytem, you should now have a rooted LG G5 with TWRP and SuperSU installed!

I'll try this later tonight, I spent the whole night yesterday trying that. Thanks in advance. ???

Didn't work for me. Thanks for this though. The script actually made it's way through this time (multiple times at this point), but whenever I try to adb reboot recovery I get the "No Command" screen (which I believe is still the stock recovery?). Success all the way through. Don't know what I could be missing.
Also tried manually pushing the recovery image via adb thinking there might be an "Internal Storage" (as seen by pc) vs "/storage/emulated/0" on the phone. No dice either way.

To me it seems like your recovery is not flashing, make sure to download the latest version of TWRP, rename it "recovery.img", and place on the internal storage of the device. If still doesn't work, try a complete clean start. Relock and unlock your bootloader again.

To be safe, I would remove "others try at your own risk" as it will not work and could possibly brick any model other than the H830 and H850. All other models are bootloader locked and I have tested myself; it won't work on anything else.

It worked! Thank you so much.

It worked! Thank you!!!👍👍👍

If you however, already have an unlocked bootloader, feel free to skip this step and go on, although in the end you might have to return to it if you get a "bootloader locked" message in the Recowvery script.
What do you mean with thiz sentence? We cant unlock our bootloader its not supported, can we still try this method?

Will this trigger some flag or fuse? Or with the flash of the firmware though lgup and locking the bootloader will create a Perfect stock device?

Can someone confirm it works on H850

No, you have to have an unlocked bootloader. I meant if you already unlocked your bootloader, you can skip this step. Possibly it will work once we get bootloader unlocks for other variants of the G5.

Do I have driver issues? Adb recognizes phone when turned on. When in fastboot only waits for device to connect.

The drivers in the post should work for both fastboot and adb. What do you mean, "when in fastboot only waits for device to connect"? You can run the "fastboot devices" command there to see if the device is recognized.

Will not let me run any commands. Just says waiting for device. Crazy, I know.

adb and fastboost not recognizing my phone even after installing drivers

Finally got root back. My problem was getting adb to work but I had no problems with minimal adb and fastboot. Thanks for the tutorial.

Will we be able to flash the current roms that our out?

so this is what i am running into. I know with 100% certainty that the device is oem unlocked. I get the whole, "your device software can not be checked for corruption" screen and everything.
i started the process completely stock, with oem locked. I unlocked it as per your instructions and followed everything closely as far as I can tell. i have tried to re-lock oem . reboot and then unlock it again twice, as well as rebooting pc and G5 multiple times. usb debugging is turned on, and usb options are set to file transfer. still same result.
Any ideas?
EDIT: i will leave the whole post up in case some one makes the same mistakes i did and this helps them out. What i needed to do to fix this was simply set "use usb connection for " to photo transfer instead of file transfer.
Now i am stuck on :\Users\test\Desktop\LgG5 RooT\minimal_adb_fastboot_1.4.1_portable>adb reboot recovery
error: no devices/emulators found like another person before me. hopefully this will be figured out soon
EDIT#2: used adb reboot recovery command with phone turned on and on main screen of launcher, not fast boot, like i was trying at first. and twrp loaded up fine.
dont have a sd card to put superuser.zip on and it seems like i can't reach the internal storage download folder through twrp, or atleast i could not find it, so i ended up sideloading it by going to sideload in twrp and typing "adb sideload SR1-SuperSU-v2.79-SR1-20161221223537.zip"
into it.
i hope that documenting all my mistakes and solutions for everyone to see will help someone running into the same problems i was.

*SOLVED* Embarrassed to ask for help - but please help!

Hi guys,
Unable to boot after c*cking up a manual upgrade from B10 to B11 on my A2017G and would love your input. I feel like if I can just install TWRP again it should be an easy fix. Here's some specifics:
1. my phone is unlocked, rooted and running stock firmware.
2. I was trying to install stock recovery to install the B11 update. I did so but also tried to install another zip (B10 bootloader?) which I seem to have flashed wrong. Now just get the screen as shown on attachment and cannot boot.
3. Stock recovery seems to have been flashed and I can boot to this. From here I can boot to bootloader but can't seem to do anything from there.
4. I try update via ADB with the sideload command, but get the message "E:footer is wrong. E: Signature verification failed. Installation aborted".
5. I try to Update from SD as have the firmware zip file and TWRP on the root of my external SD card, but get the message "Couldn't Mound /sdcard, aborted."
6. The only time my phone shows as a connected device in ADB is when I try to sideload files. No other ADB code seems to work, only get the message "error: closed" on the terminal.
Assuming I've got all the firmware files (and full backups on my external SD) I feel like if I can just install TWRP again it should be an easy fix. So, any ideas on how I install TWRP given situation above?
Best,
Neil

Hi, thanks for your reply. Unfortunately not, just get the message "error: closed" in the terminal. Is there a button combination I could press in order to get into EDL?

Try vol+ + vol- + power

it seems that the only time my device will show as connected in ADB is when I navigate through Recovery and select the "Apply Update from ADB" option. But even then, whilst it shows as connected, it only seems to allow the "sideload" command. Please see screenshot of Terminal. So at no other time will it show as a connected device.
Similarly, to have it show up in Device Manager, it'll only show when I switch the phone off, hold down Vol+ & Vol- and attached the power cable.

You are still on MM. So you are able to boot into bootloader.
adb reboot bootloader
fastboot devices
Now it should show your device as fastboot
If so you can now flash recovery with “fastboot flash recovery recovery.img“

Thanks for your reply. Unfortunately as mentioned the only time my device shows as connected in Terminal is when I select "Update via ADB" whilst in recovery. Otherwise the device never shows as connected in adb.
So unfortunately fastboot doesn't seem to be an option for me.
Perhaps my drivers are out of whack but assuming what I've done to my phone hasn't changed that, it must be something PC - side.

But what if it shows your device as sideload? Can't you there reboot into fastboot?

No, it doesn't accept the command. Only one accepts is sideload. You can see from my screenshot a few posts back that the device is connected but shows different to how it normally would.

Breakthrough!
I seemed to follow the steps I've tried 100 times today and I now have TWRP installed again!
Thanks again to those who helped

Complete Rooting Guide!

I have seen a lot of people using unofficial and third-party methods to root, which can result in a lot of adverse circumstances to say the least.
So I'm presenting a complete noob-friendly guide to rooting.
Prerequisites:
1. A computer ( I'm using Windows 10 but any OS would do)
2. A USB cable
3. Basic computer know-how
Part 1 (Getting computer ready)
Download sdk tools (adb and fastboot) from here
Note that in the entire guide I'm using official products.
So in Windows, download the zip and extract it in any folder.
Now download latest twrp recovery from here
The lastest version as of 7th August, 2017 is 3.1.
The downloaded file will be named as twrp-x.x.x-0-x3.img.
Now rename this as recovery.img (this will make our work easier)
Now move that file to platform-tools folder which we extracted earlier.
Also, I suggest downloading Intel USB drivers for Android from here
Part 2 (Getting Phone Ready)
Unlocking bootloader didn't format my phone but taking a backup is still important.
Now go to Settings<About Phone and click on Build until it says "You have become a developer"
Now back to main settings menu and find "Developer Options". And turn USB debugging on.
Download magisk install.zip, unistall.zip ans apk from here
Now connect your phone to PC via USB cable.
Step 3 (Rooting!!)
Now open platform-tools folder and press Shift+ right click.
Select "open command prompt here".
Now a terminal will open.
Type
Code:
adb devices
Now you will get a prompt on your phone. Accept it.
Now type
Code:
adb reboot bootloader
Your phone will automatically reboot and fastboot will come up.
Now type
Code:
fastboot oem unlock
[Alert! If you get <waiting for device> right click on start menu, select the unrecognized device and install Intel driver in it. Google for detailed instruction]
The process will start and you will get something like
(Okay ....)
(Okay....)
And type prompt. Now type
Code:
fastboot flash recovery recovery.img
Flashing will start.
When you get type prompt again, type
Code:
fastboot reboot
And when the screen switches off, hold power up+power button.
(
Code:
fastboot reboot emergency
should work but it's effect was same as
Code:
fastboot reboot
If you get something like red state... verification failed... Then it's a good news.
Wait a few seconds and then twrp will launch. I suggest swiping on the first screen
[because letv is almost dead and we can't expect any updates. Plus my bootloader was relocked in my first attempt when I didn't swipe.]
(I suggest wiping dalvik cache and cache)
Now you can just reboot your phone normally.
Now install magisk apk.
Now reboot again to recovery. (Easiest way is Update app>tree dots menu> reboot to recovery)
When twrp starts, go to install> download and find magisk zip. Swipe to install.
Reboot and you have a fully rooted phone!!

Intel drivers worked for my leeco le 1s. Ideally, Intel drivers should work for all devices.
I'll make a tutorial with screenshots on setting up the drivers whenever I get time.

There was a prompt for TWRP update and Magisk Update.
After it has started showing Orange State instead of Red State.
The phone got rebooted and all installed apps were deleted.
Xposed got uninstalled.
Playstore, Googlemaps got unistalled.
Camera is working.
Calling is working.
Now it shows Orange State.
Is it safe.
Can we bring it to red state?
As per this link
https://www.androidauthority.com/verified-boot-warnings-in-android-6-0-marshmallow-650368/
Orange warning: Your device is in an “unlocked” state. This means that your operating system can’t be checked to make sure that it’s safe to use.
Red warning: The operating system on your device has been changed or corrupted and is not safe to use. The device may not work properly and could expose your data to corruption and security risks.
Orange State seems to be a better state than red.

Flash eu firmware using msmtool mod (https://www.xda-developers.com/t-mobile-oneplus-8t-rebrand-without-bootloader-unlocking/) (if msmtool doesn’t work make sure windows is in test mode with proper qualcomm drivers) (if your device bootloops and you can’t recover it just flash it again with msmtool, power it off and power it back on holding both volume up and down) Recommended to use Command Prompt commands instead of powershell (type cmd in platform-tools directory) https://developer.android.com/studio/releases/platform-tools
Unlock oem bootloader
Enable developer options (click build number several times)(make sure you’re connected to internet)
Enable oem unlocking, advanced reboot, usb debugging
Reboot to bootloader/fastboot
fastboot oem unlock
Unlock bootloader
Boot back into oos, (repeat steps I. ii. And iii.) or (boot directly into fastboot by holding volume down while
booting)
Flash boot, dtbo, and recovery (https://mirror.math.princeton.edu/pub/lineageos/full/kebab/20220818/)
fastboot flash boot (path to boot.img)
fastboot flash dtbo (path to dtbo.img)
fastboot flash recovery (path to recovery.img)
Download firmware (https://kremowka.xyz/files/8fw/)
Enter recovery mode, enter fastbootd
Advanced > enter fastboot
Follow https://wiki.lineageos.org/devices/kebab/fw_update to flash it, and without rebooting sideload
LineageOS 19.1, sideload mindthegapps, then reboot. https://wiki.lineageos.org/devices/kebab/install fits in
there somewhere
Open notepad, copy commands from lineage, save as (file name).bat, drag into powershell from file explorer
(flash ram separately for safety) I named mine “flashfirmwareforoneplus8t.bat”
Be careful with ddr4 vs 5. do not brick your phone. Ddr4x is ddr4 for these purposes.
Without rebooting, enter recovery > apply update > apply from adb (it should say version 18.1 in the top left)
adb devices (to confirm phone is connected properly and device drivers are configured properly)
adb sideload (path to lineage 19.1 .zip)
Sideload will likely get stuck at 47%. This is normal. Just wait.
Volume up to go to back arrow, advanced, reboot to recovery (make sure it says version 19.1 now)
adb sideload (path to mindthegapps .zip) note that most gapps packages will not install properly as they are
too large. Just download them all from google play store once booted.
Signature verification failed will pop up, just confirm “yes”
Reboot recovery?
adb sideload (path to copy partitions .zip)
Back > Reboot system now
It may say “can’t load android system your data may be corrupt” just factory data reset it’s fine unless you have
data you want to keep then you’ll have to google it, I don’t know how to recover that and you should’ve done
that before this step (do it in fastboot, search up adb shell pull)
If the start page has clouds and blue then good job you loaded gapps properly. If it’s not then something
happened.
OPTIONAL (if you want magisk/root)
Go into settings, enable developer options (tap build number repeatedly) make sure usb debugging is on
Search in settings for “advanced”, click “advanced restart” and enable
Hold power button, restart, recovery
Apply update > apply from adb
adb devices
adb sideload (path to magisk .apk)
Signature verification failed, install anyway
Volume up to go to back arrow, reboot system now
Boot into device, reboot, magisk should appear, click on it and click accept on whatever it prompts
Open magisk, do whatever it prompts. To install a file, drag whatever module .zip you want in, make sure file
transfer is on
DO NOT USE ACC OR ACCA (battery manager) FROM F-DROID IT SOFT BRICKED MY PHONE
What I use: Safetynet universal fix and raven.A12L (spoofs as pixel 6 pro to let safetynet work)
Install from storage
Order I did it in was safetynet then raven, rebooting between each one but I'm not sure if it matters
Install safetynetfix, then go into settings, click zygisk, click enforce denylist, click 3 dots, show system apps, click
google play services, google play store, and carrier services (the square check box next to the name, make sure
every check below when you open it as a dropdown menu is checked
Reboot phone
Now you can download whatever you want
If you install twrp, make sure you are using android 12 version and not android 11, android 11 twrp will destroy
your recovery if you try to use it on android 12.
Add on: If your phone is not detected by your pc, or is detected as “MTP” with an exclamation mark, you do not
have the right drivers. There are plenty of resources online to fix this, but one that I had trouble with was that I
was on windows 10 N instead of whatever the other version is, which doesn’t come with “mediafeaturepack.”
You need to install that on your own from https://www.microsoft.com/en-us/software
download/mediafeaturepack, or, if your device isn’t listed, go to windows application “optional features” and
add it from there.
If your computer won’t download qdloader 9008 qualcomm drivers through device manager, there are a few
things i’ve tried to fix it. Make sure you have correct drivers
from https://www.catalog.update.microsoft.com/Search.aspx?q=qualcomm hs usb 9008
“The system cannot find the file specified”
Open command prompt as administrator
Type DISM /Online /Add-Package /PackagePath:"Full path of .cab file"
I put mine in C: drive folder but I'm not sure it matters
Also I'm not sure which one of the three I downloaded from the website. Did not cause any issue downloading
and trying to install all three, let me know if you figure out which one works. Maybe you need all three, I don’t
know.
If that doesn’t work, do sfc /scannow
Open windows update, make sure all updates are applied and restart windows (make sure you go to optional
updates and select qualcomm drivers)
Fastboot won’t connect
Make sure you’re using a usb 2.0 port instead of a usb 3.0 port, and make sure your usb cable is a data cable.
Google the difference if you don’t know what it is. Download usb drivers
from https://developer.android.com/studio/run/win-usb, open device manager, see if anything is there, if it
shows something in “other devices” click on it, click update drivers, browse my computer, let me pick, have disk,
and then browse to android_winusb.inf and click update, click bootloader interface. If you get “error 10 device
won’t start” when installing bootloader interface, one possible solution is to disable driver signing.
Open command prompt as an administrator (doesn’t have to be in platform tools directory)
bcedit /set testsigning on
Reboot, try to install driver again.
If your device is bootlooping, and you enter fastboot after updating to a12 firmware AND you have magisk\
modules downloaded AND you have twrp installed, do not press the up volume button, only cycle through
options with volume down, because it may enter an option cycle and you won’t be able to do anything unless
you fastboot flash boot twrp.img.
It’s recommended that as soon as you root, you backup persist.img, which contains imei info (you don’t want
that to get destroyed) I am unsure if there’s anything else device specific you need to backup, I've heard
vendor_image may be but it’d not as important as persist.
To backup persist.img, put phone in recovery, type in command prompt or powershell
adb shell dd if=/dev/block/bootdevice/by-name/persist of=/tmp/persist.img
adb pull /tmp/persist.img persist.img
This should save persist.img to your computer. Back it up somewhere you keep important things. Also don’t
give it out at random as it contains your imei number, not sure what the consequences of that could be but
nothing good is likely to come of it.
Important shortcuts:
Power + vol up – boot into system
Power + vol down – boot into fastboot
Power + vol up + vol down – boot into edl
IF DEVICE IS BOOTLOOPING AND YOU CAN’T ENTER ANY DIFFERENT MODES, CONTINUE HOLDING POWER +
VOL DOWN IN RANDOM PATTERNS. IT HAS TAKEN ME 20 MINUTES OF RANDOM BUTTON COMBINATIONS TO
GET INTO FASTBOOT FROM A BOOTLOOP. YOU WILL ALWAYS BE ABLE TO EXIT A BOOTLOOP IF YOUR PHONE
IS PHYSICALLY UNDAMAGED.
If VoWifi doesn’t work, pixelify dialer can get it working. Probably also just any custom dialer, but I like Google
dialer. Wait for the interface to change slightly, don’t clear data until you’ve waited at least a minute or two and
closed and reopened it a few times, but if it doesn’t change after installing pixelify then force close, clear data,
and wait a minute or two, reopen, and then wait. If it continuously doesn’t change you can reflash pixelify.
Note – If using pixelify module, disable auto update for android system intelligence, it will break gboard
translate and possibly slow down device.
You can also use magisk module “mindetach” to detach com.google.android.as from play store, which will fix
any auto update bugs. Credit to vewu for showing me that

How can you claim this 'works on locked bootloader', when right at your ( 2) you say 'unlock bootloader'. And if your instructions require unlocked bootloader (which they surely do), then they are useless, because once your bootloader is unlocked, you can simply flash Magisk with recovery.

What does this have to do with your 'working on locked bootloader'? That statement is false. You can't flash anything on locked bootloader, and if you unlock bootloader, then you can simply flash Magisk via recovery without the need for your 'method'.

seems to have worked for me. i meant "working on locked bootloader" as in it include steps to unlock. it's also a guide to installing lineage, not just magisk. i'm not sure what issue you have here, it's a specific tutorial for a specific problem.

It's just a decription in thread name that is a bit misleading.
At first it appears like it can be done on locked bootloader.
And it's obviously not, as stated in your instruction point #2.
Otherwise, nice tutorial.

Lenovo M10 Plus 3rd Gen Root Guide (TB125FU)

Notice! This process also completely resets your tablet! Backup all files and information.
This is just me documenting my process for rooting my tablet. I am not responsible for any damage or lost information due to the process changing, errors in execution, or mistakes in my documentation. Let me know of any errors, corrections, or updates that may need made.
Thank you to contributors to the thread linked below for the information provided that allowed me to create this more detailed root guide.
Custom Rom / rooting Options vor TB-125FU (Lenovo Tab M10 Plus 3rd Gen)
Hey everyone, I've been looking for options to Install a custom Rom or root since I bought the Tablet several month ago. It seems like there are some options for the Full Hd Version, but I have a hard time finding anything useful for the 125FU...
forum.xda-developers.com
This process was completed on Model: TB125FU
Follow documentation at your own risk!
First I updated my tablet until it was the newest system update available. For me that was version "TB125FU_S000118_220927_ROW"
Step 1 - Install tablet drivers on your computer
Download drivers folder and unzip
https://forum.xda-developers.com/attachments/android_adb_interface-zip.5741369/
Plug tablet into computer
Open Device Manager
You’ll see a line item labeled “ANDROID” with a yellow exclamation mark
Right click on it and select update drivers
Select Browse Computer and navigate to the unzipped driver folder
Make sure the Include Subfolders box is checked and select Next
This will install the drivers for the tablet
Step 2 - Unlock your tablet for usb debugging
Open settings on your tablet
Search for “build”
Click “Build Number”
Click the Build Number box seven times to unlock developer options
Close and reopen the settings app
Under System there is now a Developer options, open it
Toggle the selections for OEM Unlocking and USB debugging
Step 3 - Obtain boot.img
Download and install Lenovo LSMA
https://support.lenovo.com/us/en/downloads/ds101291-rescue-and-smart-assistant-lmsa
plug your tablet into the computer
run program, select rescue
check the allow USB debugging popup on your tablet
select tablet in the LSMA program and select the allow popups on your tablet
select Download when it shows the firmware for your tablet
DO NOT CLICK START RESCUE
close the program when it finishes downloading the ROM
The ROM will download to C:\ProgramData\RSA\Download\RomFiles
Make sure ROM folder name matches the current system update version on your tablet
Copy from the downloaded ROM folder “boot.img” to your tablet
Step 4 - Modify boot.img
Download Magisk apk from the official Github page
https://github.com/topjohnwu/Magisk/releases
install APK on your tablet
open Magisk
Select Install
Select “Select and Patch a File”
Navigate to the location you copied the boot.img file and select the file
Select “Let’s Go”
Wait for flashing lot to say “All done” indicating it modified the boot.img file
Transer modified file to your computer, for me it was called “magisk_patched-25200_rgIWh.img” I then renamed it “magisk_patched.img” to make future typing commands shorter
Step 5 - Unlock bootloader and flash modified boot.img
Download Minimal ADB and Fastboot Tools
I chose to download the portable version
https://forum.xda-developers.com/t/tool-minimal-adb-and-fastboot-2-9-18.2317790/
unzip folder
Place the modified .img file in this folder as well
Navigate to this folder, right click and launch a Command Prompt
Plug in your tablet to your computer if it isn’t already
Type “adb devices” to confirm your computer sees your tablet
Type “adb reboot bootloader” this should reboot your tablet into fastboot
Type “fastboot devices” to confirm the computer sees your tablet
Type “fastboot flashing unlock” read the instructions on screen which will tell you to press the volume up button (volume button closest to power button) to unlock bootloader.
Press the volume up button, It will say it was successful, wait a few seconds for the tablet to return to fastboot
Type “fastboot flash boot magisk_patched.img” and when you hit enter you should see a transferring status on your tablet (if you named your modified .img file something else, type that into the command instead)
When you see the transfer is complete type “fastboot reboot” which will restart the tablet.
The tablet should now be rooted which will completely reset the tablet. You will need to setup the tablet again and reinstall the Magisk app from the official Github. The Magisk App should now have superuser controls
You can relock the bootloader and return the tablet to factory image. IT WILL WIPE ALL DATA AGAIN!
To unroot you just reverse a couple steps.
Put the original boot.img (Make sure it is the boot.img of the same version ROM) in the Minimal ADB and Fastboot Tools folder on your computer
Navigate to this folder, right click, and launch a Command Prompt
Plug in the tablet to your computer
Type “adb reboot bootloader” this should reboot your tablet into fastboot
When the tablet reboots into fastboot type “fastboot flash boot boot.img”
When you see the transfer is complete type “fastboot flashing lock” read the instructions on screen which will tell you to press the volume up button (volume button closest to power button) to lock bootloader. Press the volume up button.
Type “fastboot reboot” which will restart the tablet
You tablet should now be back to normal.
***Note, if you relock the bootloader first it will not let you flash the original boot.img file. If you make that mistake as I did once you'll be able to manually startup recovery mode by first powering off the tablet by holding down the power button, then boot into recovery by holding the power button and the volume up button until the recovery screen appears. Then you can unlock the bootloader again.

Hello,
Please can you confirm that the model you tested is the same as
Lenovo Android TB125​ZAAJ0198SE​
The one above is a mediatek helio G80 4GB+64GB 2000*1200 resolution with Android 12 (bought some days ago, for sure it is M10 Plus 3rd Gen).
Thanks in advance.

Mine is: ZAAJ0401US
The process detailed above should still work on yours. Remember, you will be downloading the boot.img that Lenovo is recommending for your tablet, not using one I uploaded. So you will be rooting your specific file.
I doubt there would be differences between our ROM anyway but even if there were, it wouldn't effect you be because you are creating your own rooted .img.

Thanks for this guide. What system app did you uninstall after rooting?

I didn't remove any system apps when I rooted. I'm sure some are extra and can be removed safely.

Sorry, what is the reason for rooting then, when there are no custom roms yet?

Some apps require root access.

fastboot flash boot magisk_patched-25200_ofAPj.img
Sending 'boot_a' (98304 KB) OKAY [ 2.660s]
Writing 'boot_a' FAILED (remote: 'unknown command')
fastboot: error: Command failed
Click to expand...
Click to collapse
Now what? The bootloader is already unlocked.
EDIT: I had to use the volume keys to select "recovery mode" which opens a menu. From there I have to select "fastboot" (not "bootloader") which displays "fastbootd" (note the "d" on the end), then fastboot commands work.
BUT, after flashing the boot.img, it just powers off after the logo, no option to enter any kind of recovery, no USB connection. At most, if I hold Power for 15 seconds, then release and hold again, sometimes it turns on, and then if I hold VolUp, it boots to a recovery menu, but the only options are "try again" and "factory data reset". if I reset, it shows the animation for half a second, then shuts down.
On this menu it appears in "adb devices" as "unauthorized".
UPDATE: I was able to use Lenovo's "Recovery and Smart Assistant" tool to repair, but it has to be run on a Windows machine (will not connect in VirtualBox). It doesn't recognize the serial number, but by selecting "help finding serial" there's an option for manual entry of model number.
Choosing TB128FU and following the directions I was able to flash the stock firmware, but, the tool downloaded the wrong version. After flashing, the device claims the firmware isn't compatible with the hardware, and shuts down.
To fix this, I've had to find "TB128FU_CN_OPEN_USER_Q00012.0_S_ZUI_13.5.365_ST_220526_qpst" online. The tool downloads to C:\ProgramData\RSA\Downloads\RomFiles. You need to replace the contents of the folder in there (back it up!) with the contents of this, then it will flash a working firmware. (I think you can also use this to flash the patched boot.img, but I haven't tried). The only catch is, this is the Chinese ZIUI firmware, not the Global firmware it came with. It can be used in English, so I might keep it if I can't find the correct Global firmware.
https://wiki.postmarketos.org/wiki/Lenovo_Tab_M10_FHD_Plus_(lenovo_tbx606) PostMarketOS Wiki mentions that another file needs to be flashed any time you enter fastboot to prevent this brick. The article is for a different model, but probably the same applies.

I'm not sure why you got that error if the bootloader was unlocked. My patched .img file only failed like that when I failed to unlock the bootloader first.
Did you toggle the "OEM unlocking" in developer options on the tablet before trying to unlock the bootloader with command prompt commands?
When the bootloader is unlocked the tablet gives a warning message for a few seconds on every boot telling you that the bootloader is unlocked.

The "OEM unlocking" was grayed out saying the bootloader is already unlocked, and it does show the message at startup.
The problem might be that this is model TB128FU (not TB125FU) which is only sold in China, so it doesn't accept the same firmware. I don't know how the seller put the global firmware on it originally.

ok, i think i understand. Your tablet model number is different.
When going through the rooting process it downloaded the wrong version for your tablet without you realizing it so you patched and attempted to install the wrong version of ROM boot.img.
If so it means it is extra important to follow the line in step 3, "Make sure ROM folder name matches the current system update version on your tablet"
It is weird though that the Lenovo Rescue Tool didn't download the correct software for your tablet.

Does anybody know how to unlock bootloader for TB128XU? It is the same tablet but with Snapdragon SOC.
I am failing on unlock command. Both of these won't work :-(
fastboot oem unlock

So everything worked great for me.
As a launcher I now use the Microsoft Launcher.
Nice interface and features.
The OTAs with Magisk Root also work great.
As described by the developer.

Thanks for this! I haven't rooted an Android device since Gingerbread (2.3) in 2010, so it was good to have a basic guide for the newer stuff.
One thing I noticed: Step 1 says to find the "Android" device in Device Manager and manually install the drivers. However, that device didn't appear in Device Manager for me until I booted into fastboot mode. So effectively I had to move step 1 to instead be later, immediately after this sentence:
Type “adb reboot bootloader” this should reboot your tablet into fastboot

check the allow USB debugging popup on your tablet
select tablet in the LSMA program and select the allow popups on your tablet
select Download when it shows the firmware for your tablet
DO NOT CLICK START RESCUE
close the program when it finishes downloading the ROM
The ROM will download to C:\ProgramData\RSA\Download\RomFiles
Make sure ROM folder name matches the current system update version on your tablet
Copy from the downloaded ROM folder “boot.img” to your tablet
Step 4 - Modify boot.img
Download Magisk apk from the official Github page
https://github.com/topjohnwu/Magisk/releases
install APK on your tablet
open Magisk
Select Install
Select “Select and Patch a File”
Navigate to the location you copied the boot.img file and select the file
Select “Let’s Go”
Wait for flashing lot to say “All done” indicating it modified the boot.img file
Transer modified file to your computer, for me it was called “magisk_patched-25200_rgIWh.img” I then renamed it “magisk_patched.img” to make future typing commands shorter
Step 5 - Unlock bootloader and flash modified boot.img
Download Minimal ADB and Fastboot Tools
I chose to download the portable version
https://forum.xda-developers.com/t/tool-minimal-adb-and-fastboot-2-9-18.2317790/
unzip folder
Place the modified .img file in this folder as well
Navigate to this folder, right click and launch a Command Prompt
Plug in your tablet to your computer if it isn’t already
Type “adb devices” to confirm your computer sees your tablet
Type “adb reboot bootloader” this should reboot your tablet into fastboot
Type “fastboot devices” to confirm the computer sees your tablet
Type “fastboot flashing unlock” read the instructions on screen which will tell you to press the volume up button (volume button closest to power button) to unlock bootloader.
Press the volume up button, It will say it was successful, wait a few seconds for the tablet to return to fastboot
Type “fastboot flash boot magisk_patched.img” and when you hit enter you should see a transferring status on your tablet (if you named your modified .img file something else, type that into the command instead)
When you see the transfer is complete type “fastboot reboot” which will restart the tablet.
The tablet should now be rooted which will completely reset the tablet. You will need to setup the tablet again and reinstall the Magisk app from the official Github. The Magisk App should now have superuser controls
You can relock the bootloader and return the tablet to factory image. IT WILL WIPE ALL DATA AGAIN!
To unroot you just reverse a couple steps.
Put the original boot.img (Make sure it is the boot.img of the same version ROM) in the Minimal ADB and Fastboot Tools folder on your computer
Navigate to this folder, right click, and launch a Command Prompt
Plug in the tablet to your computer
Type “adb reboot bootloader” this should reboot your tablet into fastboot
When the tablet reboots into fastboot type “fastboot flash boot boot.img”
When you see the transfer is complete type “fastboot flashing lock” read the instructions on screen which will tell you to press the volume up button (volume button closest to power button) to lock bootloader. Press the volume up button.
Type “fastboot reboot” which will restart the tablet
You tablet should now be back to normal.
***Note, if you relock the bootloader first it will not let you flash the original boot.img file. If you make that mistake as I did once you'll be able to manually startup recovery mode by first powering off the tablet by holding down the power button, then boot into recovery by holding the power button and the volume up button until the recovery screen appears. Then you can unlock the bootloader again.

By orange state I assume you are describing the unlocked bootloader warning screen.
Unfortunately I don't know of a way to get rid of that delay and warning screen from the boot process. It should not have any effect on your tablet other than just notifying you that the bootloader is unsecured. Rooting a tablet does this and creates a more vulnerable system state that the manufacturer wants to make sure you are aware of. The tablet should boot normally after the few second delay.
