Im new to the Droid 4 scene (came from droid 2 global) and have been reading up on the ics leak that is out. I do not want to permanently install this and was wondering if its possible to do so using safestrap. If so, how am I able to do it? Do I boot the phone up into safestrap and enable safe mode? Then install from zip? Will I be able to revert to my current gb backup if I do it this way? Thank for help.
