Bootton.G is a SIS file that installs a small software component that resets the device. This component will be executed automatically after installation and at system start up. That causes the reboot to fail and leaves the phone in an unusable state.
Once detected, the F-Secure security product will automatically disinfect the suspect file by either deleting it or renaming it.
Disinfection for the cases when phone cannot start up
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
