Hi,
I Tried to unlock it but it failed went to twrp flashed , now its totaly bricked tried almost everything but no success, test point cant flash even with 9008 ok with drive signature off, tried qfil but got sahara fail error.

Xiaomi Redmi 4 prime.

I cannot believe it was that easy. I got the unlock authorization from xiaomi 2 weeks ago and not in this world I could unlock the bootloader via the unlock tool.

Boot into EDL mode, downloaded a few different flash tools, the one that worked was the MiFlash 2015.10.28.0.
the one from the official website MiFlash 2016.08.30.0 DIDN'T recognise my phone at all.

I have a few warning in twrp about encrypted storage, but I just ignored it. I just wanted to root the phone.
Also, no need to flash supers separately, in twrp, advanced, root works 100%.

Thanks mate, you made my day!!!

i think you do something wrong with the Kernel otherwise its working with us, with the Test point method. but try to use different Flashing software, and specifically. MiFlash 2015.10.28.0.
MiFlash All Versions

I have done this, and it works, but now i want to install the rom again in a clean way... have i only to format or wipe and flash a rom again? or will it brick?

And what about if I have done this and I want to do it in a official way? How can i reverse the process and come back to factory?

For a clean installation copy the method under the following video. And for official unlocking method, you have to flash a fastboot ROM in edl and then try the official method. And with flashing in edl, you will get on stock (factory) ROM.
