- There are some models when the faulty update will hang on fastboot because the previous recovery has been changed. Here my device uses the global NA rom and has rooted the device, and when I updated it from v1.18 to v1.20, when booting up the recovery system failed, I was taken to the fastboot screen and stopped at the fastboot screen.
*TUTORIAL:
- S1: Install driver zte+usb android and adb fastboot tool (if you haven't).
- S2: Copy file recovery.img (of rom global you use) to folder adb
- S3: Open folder adb and open cmd cd to folder adb and type command:
fastboot devices //Check if the device is connected, if not then review the driver
fastboot oem nubia_unlock NUBIA_NX629J
fastboot flash recovery recovery.img
fastboot reboot
Done

Hello,
This is my first post on how to root and install TWRP recovery on the Teclast Tbook 11 (E5A6) android 5.1
The TWRP works with touch and I haven't encounterd any problems with it
I have not created the TWRP, it is made by nik2670
We only flash or boot the recovery, then install SuperSU 2.82- 201705271822. Nothing else !
Sorry for the mirrors. (I will remove them if you're the owner)
Be sure to have ADB drivers v1.4.3 installed before you continue.
Download TWRP 2.8.7.0. Recovery Tbook 11 and ADB and Fastboot and put it in a folder on your desktop
Enable USB debugging on your tablet (Settings->Developers->usb-debugging)
Connect your tablet with your PC
Open up a CMD prompt in the folder you have your ADB. Win+R type CMD, hit enter. Copy the path of ADB and put in the CMD prompt
Code:
cd [path]
Mine was cd "C:\Users\Thermaltake\Desktop\ADB FASTBOOT FILES WINDOWS"
In the CMD prompt, type
Code:
adb devices
If you see your device you good to go.
Type
Code:
adb reboot bootloader
your tablet reboots, select android while it reboots
Now we're in fastboot mode, just to be sure we see the device type
Code:
fastboot devices
. If you can't see your device like me you have to manually install drivers.
Do you have the recovery.img in the same folder as ADB? Good. Type
Code:
fastboot boot recovery.img
OR
Code:
fastboot flash recovery recovery.img
to permanently have the TWRP recovery on your device (I recommand boot)
Your tablet is now in recovery mode! You can acces the internal storage. Add SuperSU-v2.82 on your device.
Hit Install->SuperSU-v2.82-201705271822->Swipe to confirm flash->Wipe dalvik cache->Reboot----> DONE !

Hi,
I am using a bootloader unlocked Surface Duo on Android 11 with ‘adb devices authorized’ and all permissions allow from developer menu.
However, when I type:
‘adb reboot bootloader’ my phone reboots and gets stuck on the Windows boot logo infinitely.
I am successfully able to enter recovery and fastbootD (fastbootd) using:
‘adb reboot recovery’ lands up in android icon
‘adb reboot fastboot’ shows menu with fastbootd and adb sideload.
If I type adb devices in the recovery, it prompts unauthorized error.
If I sideload ota update from fastbootd> adb sideload, it partially completes (94%) with unrecognized command error.
I am on non-rooted Surface Duo.
I have tried removing adb keys and reallowing from RSA several times.
I have tested different machines, Windows, Mac and Linux yet no success.
I cannot push Twrp or any boot.img file.
My goal is to be able to push a boot.img file or a twrp.img but i am unable to perform it due to lack of access to the bootloader.
Any suggestions?

If you can access fastboot mode, try flashing the boot.img via fastboot. Place a copy of your boot.img in your fastboot folder on PC and rename the file to "boot.img". Then flash the boot.img via fastboot using the following command:
fastboot flash boot boot.img
Here you can get the latest TWRP image files for Android 12 and 13 (A12/A13)

Use the Mi Unlock Tool to unlock the bootloader, note you have to go to the Mi Unlock status at the development tools to add the current Mi Account that the phone is linked to, so you'll be able to use the tool as you'll have to login to that account in the tool. There is unfortunately a 7 days wait time after you've added the account to the Mi Unlock status until you'll be able to use the tool to unlock the bootloader. Here's the latest available download link for the tool, but after running the tool, a newer version will be asked to download. Unzip the zip files and use the tools in the folder:
https://miuirom.xiaomi.com/rom/u1106245679/6.5.224.28/miflash_unlock-en-6.5.224.28.zip
You can use the Mi Unlock tool folder to use fastboot, within it is the necessary fastboot files to install the fastboot driver and to use the fastboot terminal.
Move the TWRP file into that folder and rename it to TWRP.img for so you won't have to type in a long filename in the terminal.
Boot the phone into fastboot mode. You can find the driver installer in the Mi Unlock folder if you have yet to install the fastboot driver. Open up the installer and connect the phone to the computer, that should install the driver. After that you can run the fastboot terminal.
Type CMD in the address bar in the Mi Unlock folder to open up the fastboot terminal.
In the terminal type fastboot devices to see if the phone is properly connected.
Then you can type fastboot boot twrp.img, that should boot the phone into TWRP recovery mode.
Go to the Advanced section and choose Flash current TWRP to install TWRP to the phone.
Reboot the phone into recovery mode and go back to the Advanced section and click on Install Magisk to root the phone.
You may need to format the data so the phone will boot correctly if you're having a bootloop.
Thank u so much bro , keep it up , and please if they released any custom rom except " elite rom " cause its paid one , than tell us .

fastboot: error: cannot load 'twrp.img': No such file or directory
Any help?
UPDATE:
I found the solution.
Never try to "fastboot boot" these images. If you do that, you will get a "Bad Buffer Size" error and your device will be stuck in fastboot mode.
T
o get out of being stuck in fastboot mode, run these commands:
Code:
fastboot erase misc
fastboot set_active a
Then install the recovery correctly like this:
fastboot flash recovery_ab "drag the twrp.img here"
fastboot reboot recovery
Start by downloading the official stock rom. If you had a problem with the installation or just want to go back to the original usage

Can you make a video to review that rom on p11
It has only one flaw,
The PC does not recognize the tablet, it can only be charged, files cannot be transferred and adb does not work either.
