HTC Magic with OpenEclair: Factory reset doesn't work! today I got an old HTC Magic phone with OpenEclair (Android 2.1-update) installed on it. Unfortunately there is still the Gmail account of another person linked with it, which I'd like to remove. However, for doing so, you need to do a "factory reset" on the phone. So did I, the phone rebooted, but the data (apps, settings and the account) was still there. Nothing had been removed!

Anyone has an idea what could be the problem and how to fix that?

Thx a lot!
You didn't do a factory reset then, but probably a soft reset. To perform a factory reset from the Home screen press Menu > Settings > SD card &amp; phone storage > Factory data reset > Reset phone > Erase everything. That should take you back to square one. Reply back with a comment if not.

Update:
Boot into the bootloader: Completely power off the deivce. Then hold down the Back button and press the Power/End Call button to restart your phone. Keep the back button held down till the bootloader menu appears. From here do you have an option to wipe, reset, or factory reset (or something along those lines)? If so try it.
