Messing with phone settings and configuration can sometimes cause problems, or even make your device outright unusable. In such cases, going back to default settings(also called factory setting) by performing a hard reset might be the only option.
A hard reset is also a compromise between a firmware flash and having to suffer existing troubles, and is generally much easier than firmware flashing.
This article is geared towards those looking to prerform a hard-reset on a Samsung Omnia phone. Note that evoking factory state on a device will wipe all your personal data and configuration on the phone, so you should backup everything you need (to restore after reverting to default settings).
- Go to Start > Settings, and under System tab, click Hard Reset and later “Clear all data”. You will be asked to enter a device lock code. The default code is 1234, unless you have changed it. Those of you who changed it can try the next option.
- In Phone mode, dial *2767*3855# for a restore to factory state.
Be careful while performing a reset, and use it only as a last resort (or more precisely, second-last, the last being a firmware flashing).
