HI, its my first post on xda and new to this world so i will try to be reasonable here.
i followed the steps mentioned in this thread except one, i.e. i didnt make a backup. Now my n5100 wont move beyond initial samsung logo and the recovery mode says "cannot mount / efs"
i also found a thread which makes some excellent points (see below), but i would still like to know if any of you tried this and had a similar problem. if so, did you find a DIY method
