POCO F4 GT (Ingres) – Easy Method to Repair Original Dual IMEI (Bootloader Locked, No Disassembly Needed)

Sometimes after flashing the POCO F4 GT or when an update goes wrong, the IMEI just disappears out of nowhere. If that happens, you can still get both original IMEIs back. You don’t need to open the phone and you don’t need to unlock the bootloader. The method that’s working right now is pretty simple, but it depends on a third-party service, so no one can promise how long it will stay available.

If you run into any issues, feel free to ask for help.

⚠️ Important Disclaimer

IMEI repair is illegal in some countries (Syria, Turkey, USA, etc.).
Only use this method to restore the original IMEI printed on your phone that was lost due to a software error.
