CAUTION! this method will remove all data on the device including calendar and phone numbers:
- Power off the phone
- Hold the following three buttons down - "answer call" + "*" + "3"
- Keep holding down the buttons and power on the phone
- Depending on the model, you will either get text that reads "formatting" or a start-up dialog that asks for the initial phone settings
- Your phone is now formatted and can be used again
SymbOS/RommWar uses MIME recognizer to execute the malfunctioning system component causing the phone to freeze shortly after the restart of the phone.
