How to recover K20 Pro (no unlock)

[bech59300]

Hello everbody
I bought k20 pro on rakuten in april.
I had the "mi9t pro Global beta 9.5.31 secret rom" with my phone by default.

I unlock the fastboot with miflash unlock tool then i flash the rom of my phone (official rom miui11)
I let the default option "clean all and lock"

right now my phone does not boot, i have the message "MIUI version can't be installed on this device"
And what's more when I try to flash with fastboot rom i have the message "erase is not allowed in lock state"
I cannot unlock again my phone because my phone does not boot so i cannot activate debugging mode.

If someone had a solution, it would be great.

Thanks in advance for your feedback

You must flash the original rom that was factory on your phone.
K20 Pro needs CHINA fastboot rom via miflash tool.
Check your bootloader is still unlocked....
PS/
"Global beta 9.5.31 secret rom" is a nice name for a full bloatware rom....

Hello thanks for your feedback.
Since the manip "clean all and lock" from the previous flash with miflash tool, now my bootloader is lock.
That's why it seem that i cannot flash again without problem and this message "erase is not allowed in lock state" :'(

You must unlock again. But your seller may have binned with his account.
I wish it is not...
Good luck.

You need to put your phone in edl mode.
Prey that you don't need a authorized account, and flash with miflash the original China rom of the phone,
Good luck
