PS: On instructions for second method you may want to mention you have to rename twrp image to recovery.img

My device is now stuck in the fastboot menu. It says I can navigate the menu using volume up and down but pressing either of those doesn't do anything and I can't seem to power off the device by holding the power button. Any suggestions on how to fix this?

Some people have reported that touch isn't working and partitions aren't mounting properly. I tried to fix most issues and uploaded a new version. I do not own this device personally - so i can not test the fixes. Please give me feedback for the updated version.

I just got my GPD XD+ today, thanks for the TWRP build but on mine, even with the current build (2018/04/01), I can't perform any actions. Touch still seems not to work for me. I can't get past TWRP asking me "Keep System Read-only?" Let alone see if partitions are loading correctly.
Everything is in portrait mode which is awkward for this device. What about landscape? Shouldn't it be 1280x720 rather than 720x1280?
**Update**
It would appear that my touch controls are inverted... so the fix for others, seems to have inverted my own.
**Update 2***
Well... after realizing the touchscreen was reversed for me, I was able to slide the "Swipe to allow modifications" slider but after that, I chose to reboot out of recovery since the likelyhood of me hitting something by mistake with the controls reversed was high. Being very careful, I was able to tell it to reboot to system and now the system hangs at the GPD logo.. which no longer animates... I can no longer boot into anything but recovery and fastboot.
Any theories as to what has happened? Does anyone have a Clean Stock ROM of the plus model so I can start over using adb?
**Update 3**
PsyOps pointed me towards some stock images at "forum.gpd.hk/t3-the-latest-firmware-of-gpd-game-console" and I'm back in business. Had to flash more than just recovery and boot.. had to flash system as well for some reason.

I have the same situation here.
It happened after unlocked the bootloader, so it's nothing to do with the recovery.
The adb commend return the error: device '(null)' not found.

I can't check the "recovery" box. It doesn't do anything. And the first methode doesn"t work
EDIT : nevermind, I did it but same problem as Busted77

Same thing here. Now waiting for the battery to empty. What happens after that? Will it work fine and the bootloader be unlocked?

I was being dinner and used adb commands instead of fast boot. If you have your device plugged into a computer with fastboot setup you can run "fastboot reboot" and everything should work.

Wait for the battery runs out, then recharge, it works fine and the bootloader is unlocked, the first boot will take longer and a few reboot.
And I find that any time you issue fastboot command from you pc, the xd plus will stuck and you have to wait the battery runs out.
I installed the Magisk use fastboot method, stuck again, and need to wait for the battery runs out, recharged, and evertyhing ok then.
There's another root method on Chinese forum (flash supersu pack by recovery), since I rooted by installin Magisk, I didn't try that.

No, when I stuck in the fastboot menu, the adb command return error that no device can find, I have to unplug battery or wait for the battery runs out.

"fastboot reboot" worked perfectly for me!

Fastboot stuck
Same problem here.
I installed the drivers but got the error.
Now my device is in fastboot mode but fastboot reboot etc. don't work.. And I just can't turn it off..
Im really sad.
Windows 10 x64

So.. At least I could fix the problem, I installed the Drivers (had do disable driver signature) and installed your TWRP Mod successfully but the Screen is mirrored! U can use it but its very tricky.. I could open "Install" But if I open it, twrp could not load any data it called "0MB Space" and yeah after reboot, my GPD XD Plus DON'T start..

I had the same issue, could use it inverted and mirrored but after running it and not doing anything with it, I could no longer boot into system... Only into recovery. If I tried to boot into system, the boot animation would never animate and the system would hang.
See PsyOps' reply to my question of where to find a stock rom. You can either use the provided tool or you can use adb commands to reflash your system partition... At least for me I had to flash system... Flashing boot and recovery (removing TWRP) didn't work alone...

Thanks for the advice, I spoke with him too and he already gave me the guide how to boot into Recovery Mode and then fastboot (Hold VOL+ & On Off Untill Menu apperas, then boot into recovery, then if the android guy appears press On/Off and THEN VOL+, so you're in the normal recovery mode for all the other poor user's )
And I flashed system.img, boot and stock recovery and then it booted up..
The only thing is, that I think that the SD card won't mount correctly anytime and if I plug it to the PC, I dont see the SD card and big files (like the StockROM Update 1.10 abort before its finished).
Greetings

Contact me in discord.

Could you please close the thread and delte the download link? Not even once your TWRP worked, please don't share the file anymore. Other user's will brick their device too.

Hello how to fix a black screen caused by overheating device?i dont know how to use the stock recovery i have thr gpd boot logo but after a black screen and blue led thanks

Warning: This TWRP Recovery is only useful for installing custom ROMs.
Currently there's no way to use this recovery on stock in any meaningful way without future addons
(Data partition cannot be read because of LG default encryption)
You cannot install or backup anything while you have LG Encryption enabled. A future addon can disable it.
<-- Requirements​
An Bootloader unlocked LG G7 ThinQ by any means. (official or unofficial) (G710TM Models are impossible to be supported, sorry)
More information on officially unlocking the LG G7 here: https://developer.lge.com/resource/mobile/RetrieveBootloader.dev
Running minimum LG Stock Android 9 Pie (AOSP GSI does not count)
A PC and ADB + Fastboot
The temper to read twice
<-- Needed files​
You only need this boot image:
https://drive.google.com/open?id=1FcIBNfL3_72cQwuxd2TyZSjnC-ItnNTt
For developers who want to build their own TWRP Boot image here's the device-tree for it
https://github.com/LameMonster82/android_device_lge_judyln-twrp
<-- Installation​
Step 1: Enter Fastboot mode
Connect your phone to your PC with a USB Cable
Restart the phone
While the phone is restarting hold Volume down button.
Note: Make sure you hold Volume down button before you see the black and white "LG G7 ThinQ" text
If you see the red LG Logo you either messed up or you don't have access to fastboot mode witch is another problem i can't solve easily.
If done correctly you should be in Fastboot now
Step 2: Install the boot image
Open the command prompt or your terminal (depending on what PC Platform you are)
Type:
Code:
fastboot boot [B][TWRP Boot image location][/B]
Click to expand...
Click to collapse
Note: This TWRP is only temporarily (it does not overwrite the bootimage). When you reboot it will dissapear and you will need to redo the fastboot command.
You're done. Now you can use TWRP to install custom ROMs

[CODE]fastboot flash boot_a [B][TWRP Boot image location] --set-active=a[/B]
The best way you can set the TWRP Boot image location is to manually "drag and drop" the file itself in your command prompt
Also make sure you "drag and drop" the TWRP Boot image before you type --set=active=a
Don't forget --set-active=a has 2 little lines at the beginning. No space between them.
Step 3: Enter Recovery mode
Restart the phone (using power button if you're still in fastboot)
Before the phone turns off hold Volume down and power button
The moment you see the black and white "LG G7 ThinQ" Text start clicking the power button as much as you can without letting the Volume down button.
If done correctly you should see a white screen with "Factory reset" text on top.
If you done step 2 correctly clicking yes on both prompts on the phone will get you to TWRP
For people who still have trouble getting into recovery mode here's a visual example of how to enter recovery mode (youtube) https://youtu.be/_0yoFEvIods
Note: You don't have to be in system. Rebooting from bootloader will still work

Nope. The problem is there are no blobs to use. Yeah keymaster is there but keystore module is missing from the vendor and the system. The closest thing I found was lgkm module that looks like a proprietary keystore module for lg

Hello, I am not very educated about this as I would like...
Is this recovery "persistent"? Why it is not possible to use this recovery to flash/root magisk on stock roms?
Thank you.

is it needed for magisk?
hello,
stock LG Pie (v20c) with bootloader unlocked. do i need to install this (TWRP) in order to root it with the magisk file from your drive, or will it work without?

No need to install TWRP for root. Just follow the guide there and you should be fine.

How strict is the Android Pie requirement before installing TWRP?
I have a G710VM that I'm trying to get LineageOS onto. I've already gotten the bootloader unlocked, but it seems like, so far, I can only get bootloader access by using the ULM 8.0 ROM (ULM11g). If I try the European 9.0 (EM20b) or ULM 9.0 (ULM20d) ROMs, I lose bootloader and fastboot access.
Also, is this TWRP a persistent TWRP, or semi- or non-persistent.
I also apologize in advance if I use the wrong terminology or make the wrong assumptions as this is my first attempt at unlocking a phone and putting a custom OS on it.

What error did LMSA give you? The vol-up + USB-in combo is really touchy. Maybe give it a few more tries with LMSA.
Someone else had probs like this, but was able to boot into recovery using Pwr+VolUp+VolDown combo. If that works, see if you can factory reset.

Did you try power+vol up+vol down, 10 seconds long? It reinitialize the tab.
Good luck, neighbour

Hello,
thanks a lot for you help, LMSA stuck a 67% with error "fail to rescue".
The good solution was from my french neighbour with "power+vol up+vol down" for more than 10s. I then got acces to recovery and go to fasboot mode to flash original boot.img.
I've been then able to use LMSA to rescue my TAB and it's back to life !
I just wonder why magisk's boot generated was wrong... I'll make some other try in the weekend to root my tab.
Thanks a lot.
Merci du Var !

De rien / you're welcome.
I had the same issue at 67% with LSMA.
Before I rooted the Tab, I upgraded it to Android 9 in Settings/System. Then everything worked fine.
I hope your house is safe despite this crazy rain.

This didnt work for me but maybe because the firmware that was on the tablet was 3 updates newer than the OP firmware.
It was stuck at the LENOVO boot image sadly
It took a long time but I got the tablet back trough a rescue.
The firmware was and again is: TB-X605F_S210126_191029_ROW
And I wonder if it will work if I get a boot.img from this firmware and patch it.

Thanks a million Mike! You’re the best ?
XDA can be a jungle sometimes, I though I did research but I missed both the root thread and the TWRP thread for 605F.
That would have saved my lots of time a headache haha , but I didn’t get a heart attack so it’s all good.
Anyway, the patched Magisk worked perfectly, and all is good , finally a working YouTube Vanced since my previous Xperia 2 tablet.
The only weird thing was the link issue from Lenovo’s recovery for the latest firmware, the full one, not the ota updates.

twrp has problems, with screen bootlooping in twrp when trying to install zip files, the recovery is faulty and we probably need a new tree for the fix, which i was trying to look for an official tree, but i mean we already have one and when you compile it, it produced a faulty recovery image and lenovo hasn't released a kernel source or device tree yet, but i hope i can get a fully working one

Have a look at this post.
There are so many hardware variants of the M10 now, it's probably impossible for Lenovo to release reliable kernel source. There's now even an M10 that uses SDM429 (rather than SDM450). ...and the second gen M10 FHD Plus (X606F) will use the MediaTek Helio P22T.

[GUIDE]Bootloader Unlock Realme C12

After 6 months from launch date, we finally got bootloader unlock permission on March 2nd 2020 for Realme C12 initially based on Realme UI 1.0. Later Realme gave permission for UI 2.0 too.
Before doing anything to device, keep a copy of Stock ROM from here in your PC or SD Card.
Unlocking bootloader will trip safetynet. If you want to use bank apps or some apps that use SafetyNet, then you have to pass SafetyNet. To pass it we have to use a Magisk module called 'Universal SafetyNet fix' Or use a custom rom or GSI that uses it if you dont want Magisk.
Also locking bootloader seems to lead 'Red State' in many devices. This can only be solved by going to Service Center. So be prepared for it. To get rid of it flash stock rom once even if you didn't done any modifications.
Prerequisites:-​- A PC
- USB Cable(We can use charger cable)
- Platform-tools
- Patience
Step 0 - Great! You're ready to go. Make sure to backup your phone's data before continuing on with this tutorial, as unlocking will make it factory reset (wipe)!
Step 1 - Download and Open In Depth Tool from below
For UI 1.0 https://download.c.realme.com/flash/Unlock_tool/DeepTest_realmeC12.apk
For UI 2.0 https://c.realme.com/in/post-details/1526491339024314368

"lightbox_toggle_sidebar": "Toggle sidebar"
}
Step 2 - Click “Start applying”.
Step 3 - Please read the disclaimer in detail, select the checkbox, and submit your application
Step 4 - The Application Will be checked by realme Servers..(Wait 10 mins)
Step 5 - Go back. Remove app from Recent apps. Open the app and click on Query verification status which is at top right
Step 6 - You can now click “Start the in-depth test” and the device will reboot to fastboot mode automatically. The following string will display on the screen: fast boot_unlock_verify ok
Step 7 - Now Download and install the fastboot tool on your PC and Connect the device to PC using USB cable and ready to unlock it.
Step 8 - Now you are in Fastboot Mode. Type this command
Code:
fastboot flashing unlock
in command prompt of PC and Press enter.
Step 9 - On your phone press the Volume Down key to select "UNLOCK THE BOOTLOADER” (or press the Volume Up key if you have changed your mind to select "DO NOT UNLOCK THE BOOTLOADER”).
Step 10 - Now type
Code:
fastboot reboot
. Your phone will reboot and all user data on the phone will be erased - I recommend you perform a data backup prior to applying.
And there you go! Your phone will reboot and you can set it all up again. with the ability to root and you can also install GSIs/custom ROMs/recovery!
After unlocking, flash stock rom once from stock recovery to fix some 'Red state' issue and fastboot errors that may lead to GSI booting issues. See this for flashing stock rom. With this you will also get a idea of flashing stock rom.​
Q: Will unlocking my bootloader void my warranty?
A: No, it will not. Unless you brick your device.

Relock your bootloader
Locking bootloader without flashing stock rom again may lead to 'Red State'(can only be fixed by flashing stock rom with PC). So before locking bootloader, flash stock rom in stock recovery and boot to stock rom once.
Tutorial:
Step 0 - Flash stock ROM in stock recovery.(Don't skip this step even if you haven't done any modification)
Step 1 - Download the unlock tool again to apply to exit the in-depth test.
Step 2 - Click “Apply to exit in-depth test”. You should manual operation enter the Fastboot mode(Press both the Volume down button and the Power button when power is off).
Step 3 - In the Fastboot mode, use the engineering command below on your PC to re-lock the bootloader.
- Enter the command: fastboot flashing lock​Step 4 - Press the Volume Down button to select the “Lock bootloader” option (or press the Volume Up button to select “Do not lock bootloader" and keep it unlocked).
Step 5 - Then enter command fastboot reboot. The phone will reboot. All user data on the phone will be erased - we recommend you perform a data backup prior to applying.
Thanks

We have both TWRP and custom ROMs too. But they are in C11 forums. All C11 things can be used in C12 and C15(MTK) too. So have a look at https://forum.xda-developers.com/f/realme-c11-roms-kernels-recoveries-other-deve.10991/
Also join us at Telegram by searching 'Realme C12'.

I have two questions
1. I have a Realme c12 device (Realme UI 1.0), it's device model is RMX2189 but the link you provided has only RMX2185 version. Can I flash that stock rom in my phone?
2. I am from Bangladesh, which region version should I flash? (Egypt, Combodia, Indonesia, India, Pakistan, Vietnam)

For first question, you can install RMX2185 version. Since C11, C12 and C15 use RMX2185 for stock rom ozips.
For second question, I am not sure what to do with your region.

Thanks a lot. I am facing some problems while trying to unlock bootloader. (Forgive me, I am a noob )
I have successfully installed platform-tools, granted usb debugging permission and rebooted my phone to fastboot mode from depth tool. It's showing "fast boot_unlock_verify ok".
Now if I enter the command "fastboot flashing unlock" in command prompt window, it's showing this message: "waiting for device" and nothing is happening afterwards... Am I missing any drivers? (My cable is ok)

@Shawmik
Yeah you are doing right.
But seems like drivers are not installed.
See the questions in bottom of my guide to get solution.

I don't know why I am facing these weird issues, sorry for bothering you...
I have installed the driver you mentioned in the questions section, now if I connect my phone while in fastboot mode, my PC detects it but if I give the command "fastboot flashing unlock", the command prompt still shows "Waiting for device"...
And I tried going to device manager and manually update my device drivers (as you guided), still the same

How To Guide Lock+Unlock Bootloader - Xiaoxin Pad Pro 2021 [TB-J716F]

How To Lock and Unlock Bootloader - Xioaxin Pad Pro 2021 - TB-J716F
Since I found out that the Tablet supports Project Treble I'm trying to get a GSI-ROM running on it.
Currently with many trial and error I got LiR-ROM to boot.
The first step is to unlock the Bootloader so I thought I will share the process here.
Your data will be deleted while unlocking, try it at your own risk.
Unlock Bootloader manually
Requirement: PC with ADB Fastboot
1. Go to Settings -> System -> About Phone, tab on it until developer settings are enabled.
2. Go to Developer Settings and enable "USB Debugging" and "OEM Unlocking".
3. Open Console and enter "adb devices". Allow USB-Debugging if tablets asks.
4. Enter command "adb reboot bootloader".
5. Write down the serial number shown on the bootloader screen
You can either get the unlock image via this link "http://cdn.zui.lenovomm.com/developer/tabletboot/[your sn number]/sn.img" or via the webseite
5. Go to the ZUI Unlock Website and request the unlock image
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
6. You should get a mail where you can download a file called "sn.img".
7. Flash the image with fastboot "fastboot flash unlock sn.img"
8. Enter command "fastboot oem unlock-go", bootloader will unlock now.
9. Restart with "fastboot reboot".
Done, your bootloader should be unlocked now.
Lock and Unlock Bootloader with Batchscript
I recently found a batch script for lenovo devices in an chinese forum and translated it.
It's easy and convenient to use. For unlocking you still need the sn.img from the ZUI Unlock Website.
Download BatchScript​

Thanks a lot for your contribution! Mine was unlocked when I received it but it's good to see some guides here.

What is the opposite process, to close the bootloader? Does Widevine L1 recover after closing the bootloader? In the case of doing so, can the bootloader be opened again?

@sakun-ice Sorry, I can't tell you that, sind I haven't tried it now. But I think it should be possible.
Currently I'm trying to get a Custom ROM running, if it doesn't work, I will try to install Stock ROM and lock bootloader again. If it happens, I will post it here.

Thank you very much, I hope you can install a custom rom and this tablet will not be forgotten, since it is one of the most powerful compact tablets.

@sakun-ice I got LineageOS to run on it today, but it still has 2-3 bugs.

Helloi received one unlocked with a globaoe fw without ota's and i flashed the cn one and took the boot.ipg and patched it with pagisk for root and when flashing it via fastboot the device reboots to fastboot everytipe 1nd had to reflash the fw via edl , i did flashed vbmeta img with the known command o disable verification but no success same thing again. Can anyone plz tell me how to root that crap , it was intended to root use only and took over xiaomi pad pro just because the xiaomi needs 7 days of waiting before unlocking , plz help guys .thx so much i can buy a couple beers for the helper

I'm able to flash back to China stock rom but i can't lock the bootloader.
i have placed the sn.img in both the batchscript folder and platform tools
Tried the batch script :
"
Please select your device status:
1. Fully booted
2. Fastboot mode
Status: 2
Start locking bootloader, don't disconnect device from PC!
FAILED (remote: Command not supported in default implementation)
Finished. Total time: 0.016s
FAILED (remote: Unrecognized command flashing lock)
Finished. Total time: -0.000s
If prompt says "OKAY", locking was successfull.
Use the volume keys to select "LOCK BOOTLOADER", press power key to confirm.
Done!
Press any key to continue . . .
"
Powershell :
"
PS C:\Users\weeteck\Downloads\platform-tools_r31.0.3-windows\platform-tools> ./fastboot flash lock sn.img
Sending 'lock' (5 KB) OKAY [ 0.000s]
Writing 'lock' FAILED (remote: 'No such file or directory')
fastboot: error: Command failed
"

@zeroflame15 Did install the driver correctly? For locking you don't need the sn.img, only for unlocking. And did you use the LockBootloader Script?

hmm..i'm not sure if i install the driver correctly. what should be shown in device manager? i did follow PHRS guide and installed the ADB driver but there is this !Android under Other Devices.
Any other driver that i need to install?
And should i be in bootloader mode or fastboot mode to run the command? I run the command at fastboot moder i will get the error above. If i run at bootloader mode will stuckedd at <waiting for device>

@zeroflame15 You have to be in bootloader mode. <waiting for device> is propably the driver.

i have installed all the ADB driver mentioned in this section. Is there a lenovo driver? or any settings within the tablet need to be set to?

Check out this post:
Post in thread '[Solved] Re-locking bootloader - no fastboot commands working' https://forum.xda-developers.com/t/...stboot-commands-working.4330019/post-85755663
It can be a bit tricky to get the commands working because it's not always clear if you need to be in fastboot or bootloader.
This worked for me:
Reboot to bootloader by entering "adb reboot bootloader"
After that try "fastboot flashing lock"

Thanks @zxcv88
After installing the lenovo USB driver, the !Android in Other devices was updated.
LenovoUsbDriver_v1.1.34
MediaFire is a simple to use free service that lets you put all your photos, documents, music, and video in a single place so you can access them anywhere and share them everywhere.

Sort of yes.
Initially after flash to stock china rom, i was able to OTA. But subsequent check for updates will get error saying devices is rooted.
After locked bootloader, tried OTA again and indeed there is another new updates.
Saw some chinese video for those who wanted the rooted status and also to perform OTA updates, they are using magdisk to hide the root.

its seems most difficult to lock/unlock bootloader that flash rom.....
but you need ZUI Unlock Website also for lock? cause seems need only for unlock...right?

No need for lock. Like what others have mentioned. Just a single line command and it works as long you got the right drivers installed.
