GSM ROM typically refers to the firmware or ROM (Read-Only Memory) used in mobile devices that operate on GSM (Global System for Mobile Communications) networks. These ROMs are specific to certain models of phones and are used to control the device's functionality, including connectivity, user interface, and hardware interactions.

| VoLTE missing | CSC doesn't support carrier – change CSC via *#272*IMEI# or SamKEY |
| SIM card not detected | Dirty SIM slot or damaged CP partition – try reflashing CP only |
