I recently installed Cyanogenmod on my Samsung Galaxy Mini (tass) unsuccessfully using adb push and install and then adb sideload. Both methods didn't work :( . When I booted the phone up, it came up with the usual bootlogo but didn't boot into Cyanogenmod. It just said 'A N D R O I D' in the middle right of the screen. Does anyone know how to reinstall stock firmware or even better, know how to install Cyanogenmod successfully :confused: ?
