if I change it to issues poco x3 firmware update, it are 4 million results.

I have a Poco m3 with the 'dead boot' problem. Worst buggy phone I've ever purchased.

Was it the global version 14.0.2.0.SJGMIXM

The technician in the service centre said rolling back the firmware is only possible if replace PCB.

 

Been searching for it, and according to miuirom.org it is possible using fastboot rom.

 

Is this an official site that can be trusted?

Edit: It seems Xiaomi also says it's possible.

I would check this page for good sites to download rom

https://www.reddit.com/r/Xiaomi/comments/nqi4vc/what_is_the_recommended_place_to_download/

as far as I know your android version hasn't changed still on android 12 before and after the recent updates from your previous posts you indicated your were on miui 12 and you went to miui 14

you will the information that you seek if you limited your searches to poco x3 nfc downgrade miui 14 to miui 12 since that was the miui that you were currently

when using words like firmware is can be downgrading android versions

I can download an official fastboot rom from the links you provided yesterday.

 

The miuirom.org site is not official, though it sounds credible, and they advise against using the tool available on the Xiaomi site, but suggest using their tool.

 

What are your thoughts?

I haven't used them personally but miuirom.org does get hits on the xda developers forum which i have used over the years
