Question P11 [Solved] [HELP] Bootloader unlock, Unknown Command

Search This thread
We have users with same problem (no updates).
I did it, and I finally found the problem.
I think 210421 firmware was the problem. After I flash(rescue) the new firmware, set up and toggle the usb debugging and allow unlock bootloader in developer options, turn the adb on and type

adb reboot bootloader
fastboot flashing unlock

it just successed.

Thanks :)

Can you give step by step instructions? I did all the steps until enter "fastboot flashing unlock", my screen says "waiting for device".
On P11 nothing happens.
Looking forward to hearing from you. Many thanks...
