Look for your “CARRIER_ID: XXX” which you can find when you put the phone into download mode (Power + Bixty + Vol down)
Once you have the 3 letter code that is the CSC (Sales / Region code). Use SamFirm (Download from here) to download the firmware. You can input the CSC code and Phone model (also listed as product name in download mode).
Flash that firmware, you’ll need to flash the non-home CSC to fix the lost imei and baseband so make sure you backup before flashing as non-home CSC will factory reset the phone upon flashing.
