Hola chicos, ayuden a actualizar a Android 11 pero tuve que volver a 9 pero se quedó en el dispositivo corrupto, intenté cargar el sistema desde adb pero tenga en cuenta que no tengo el cargador de arranque desbloqueado, cuando intento desbloquear con los comandos normales no puede ser, antes de cargar la rom 9 no desbloqueaba el gestor de arranque y ahora no puedo empezar a desbloquearlo, ¿qué puedo hacer? T_T

Tengo el mismo problema en mis RM3, ¿alguien sabe si hay alguna forma de activar fastboot sin la opción de depuración USB?

ZTE nubia Red Magic
Requirements:
- To Unlock Bootloader On Nubia Red Magic 3 (NX629J), you will need a computer.
- Charge the Nubia Red Magic to at least 50%.
- You need a USB cable to connect your phone to PC. (Users reported better luck with usb 2.0 port vs usb 3.0.)

Connect your rm3 to your windows 10 pc without developer options enabled. It will be a cd drive, and you can double click it to install the usb drivers

1) Enable the Developer Options
- To Enable Developer Options, Go to your Settings -> About -> Software Information -> More -> Now Tap on the Build Number 10 Times until you see a toast message “Developer options enabled“

2) Go back to settings -> Now you need to enable the OEM Unlock by going to Settings -> Developer Options and check the box for OEM Unlock and USB Debugging

3) Connect your phone to Computer using USB Cable.

4) Open a command prompt window on your computer and type: "adb devices"

5) You will see a pop up window on your phone to allow USB Debugging on your phone. Click ok.

6) Now type the commannd "adb reboot bootloader"

7) Once your phone has rebooted into it's bootloader, type in the command prompt "fastboot devices". This will list the devices connected, your phone should show up.

8) Then, enter "fastboot oem nubia_unlock NUBIA_NX629J"

9) Then enter "fastboot flashing unlock"

9) Finally type "fastboot reboot" into the command prompt.

10) From here you can install twrp, root your phone, etc.

TO RELOCK BOOTLOADER Restart into fastboot on your phone, and use the commands:
"fastboot oem lock"
"fastboot flashing lock"
"fastboot oem relock"

i am getting a error while unlocking on 8th step , it shows the error (remote: password is error!!) , plzz help , i know i am late
