Bricked or not bricked, that is the question

You can't be sure of that, sometimes the vendor correct the issue, sometimes the firmware.

Firmware it is in the stock ROM that can be flashed either through fastboot or EDL mode (be careful to not relock bootloader or you couldn't enable this time OEM unlock option). Now that you have the way more clear just do a search "how to flash stock ROM on Xiaomi devices either through fastboot or EDL mode", just keep in mind that you don't need to open the back cover of the device, usually from a device off (only on unlocked ones) you could send it to EDL by pressing both volume buttons at same time that it is connected to PC, I gave you the main tips, for the rest you will find a lot of tutorials.

Ok, thanks for everything, i think i know what to do from now on, gonna update you if i have anything new, be it a problem lol, or the device fixed

It's been some days, i tried it, everything worked sucessfully... for about 10 minutes, the screen would only work in high brightness, it would turn off (and also the digitizer) otherwise. I tooked to a technician, who swapped the screen with a brand new... that didn't work also
At this point i am assuming that this is a hardware issue with the phone, motherboard, wich is way too costly to replace, this phhone is going to my drawer, if think it can't be revived :/

Your device can boot to system and screen is unresponsive?
Now that you did unlock bootloader you can try with some custom ROMs to see if this helps, some custom ROM are built from some specific screen behaviour aka display vendors, and flashing also some firmware.

That's a great tip actually, i'm gonna fiddle about with some custom rom, but oh well, i'm not confident about it

Well, that was a dead end
Twrp has the same issues with the screen, doesn't send image nor touch funcionality
I'm tired of this device, at this point i'm gonna conclude that theres a either hardware issue or a really low level firmware
If you have anything that can help, or maybe a cheap motherboard (the one on aliexpress is ****ing expensive let me tell you that) let me know
Thanks for all Subway champ, you really helped

Solution

I had the same issues with my redmi note 5 pro. I took it to a technician he said that it happens due to moisture. He fixed it for 400 Rs

Do you know what specifically did he do to fix it? Alcohol bath?
