[Brick] How to unbrick Mi 9T COM3 - Redmi K20 / Xiaomi Mi 9T Questions & Answers

Hello people! I went back to factory the Mi 9T, but it went out completely. The computer recognizes the connection, but the screen goes black and MiFlash is COM3. How should I do?

The message was that "only nop and sig tag can be received before authentication"

the error means you need a mi account that has edl permisson but i can't help you i would love to help but i don't know much about edl sorry ^-^

I have the same problem. Phone is on edl mode. Any help?

What do you mean by "went back to factory" ? from where to where? Which ROM did u used, which one did u tried to flash?
Without more informations there isn't really a way to help you.

Deep flash cable, you can either make it yourself (diy), or buy one. As for the process, it's quite simple. Try search on Youtube. It worked for me when i had this problem long ago.

This miui version can't be installed on this device (K20 with locked bootloader)

Hello. I need help!
I have a K20 and I made the mistake of locking the bootloader with the MI 9T room.
The cell phone does not turn on because it says "This miui version can't be installed on this device". So I have no way to unlock the bootloader by the traditional method that needs the cell phone on.
the only way that it authorizes the installation of a room is through recovery, but my pc sees my cell phone as an MI 9T and it only lets me install its room, since this room doesn't boot.
I also tried in MI Flash through edl mode and it says I don't have an authenticated account. I have no idea what I can do anymore.
I would be very grateful if someone could give an idea of something.
I'm new to the forum, sorry if I wasn't so clear or if I posted in the wrong place.
