AT&T Galaxy S2, was able to get into both recovery mode and download mode fine prior to install of Android 4.0.3. Following install, of Ice Cream Sandwich, neither the back or search key works, and screen does not auto-rotate, and no longer have root privilege. Try to go into recovery mode, just goes straight to Samsung logo and loads home screen. Have tried all combinations of volume and soft keys, nothing works. Can't do it through ROM manager because I lost root privilege. Anybody have any ideas of how I can make this work?
