Question Back to stock, how to make sure I flash the correct ROM?

[i_devour_babies]

Hello everyone, I may be planning to resell my Poco X3 Pro, and for that, I want to reflash the stock ROM and relock the bootloader.

As I understand it, there are different ROM versions, India, Global, EU, etc, and flashing the wrong ROM and unlocking will brick the device, is that correct? I bought my phone from Iran, but as Xiaomi phones are often imported unofficially, the actual version of the phone may not be clear. Is there any way I can find out the stock ROM version so I can relock the bootloader? I still have the box, btw.

Thanks.

You can Figure out which Version you have by Baseband Version in System settings.

No clue which one is which though^^

I have updated the firmware several times, doesn't that matter?

As long as the ROM version is the same or newer than Firmware you won't have any problems.

Can try this website:

Xiaomi Full INFO CHECKER - FREE | XiaomiCheck.com | XiaomiCheck.com

Check Xiaomi Mi Status by IMEI or Lock code and make sure the MI status is Off before you buy or sell a Xiaomi device | MI Find Device Check | Mi Account Check

xiaomicheck.com

This is not official Xiaomi website.

Bought mine on Amazon. So only 1 year warranty

Purchase Country: Germany

The actual warranty should be according to where it is from.

In general, Global is 1 year, while Europe is 2 years. UK is also 2 years.

Could ask Xiaomi/POCO about it.

Mi Deutschland

www.mi.com

POCO Deutschland

POCO Deutschland

The non-official website could show the information probably due to the "Mi-Activation lock: On", in order for the "Find my device" function to work.

You can log into Official Xiaomi and check and or un-link

Just flash Global ROM and lock bootloader. It doesn't matter the region.
Download original ROM from here: https://xiaomifirmwareupdater.com/miui/vayu/
Use fastboot rom, don't use recovery.
