Replace YOUR_IMEI with your device's IMEI and XAA with your region code.

Additional Options

IMEI Important: You should enter your complete IMEI number. While GNSF can attempt to generate missing digits if you provide only the first 8+ digits, this may not be sufficient for downloading firmware in all cases. Using your full IMEI ensures the highest success rate.
