- SIM Card Influence: Some Grundig models restrict reset codes depending on the inserted SIM card. It is recommended to attempt the reset without a SIM card inserted.
- Network Lock (SP Lock): A factory reset will not remove a SIM Lock (Carrier Lock). If the device displays "Phone Restricted" or "Enter Network Code," a factory reset will not resolve this. A specific unlocking box (e.g., Griffin, UFS) is required to remove the network lock.
- Hardware Failure: If the device fails to power on after a reset attempt, the flash memory may be corrupted. Given the age of the device, repair is generally not economically viable.
Location: Look for a tiny pinhole on the front panel, often near the volume controls or SD card slot.
