http://forum.xda-developers.com – Hey guys new to rooting and roms, i flashed a rom decided i didn't like it i proceeded to wipe everything. and i mistakenly did a FULL WIPE of the entire phone only thing left standing is TWRP, all my backups are gone no other rom i can flash either. i know its not completely bricked since i still have access to TWRP. I would mount the sd car but it doesn't recognize the the phone and it wants me to format it. im out of ideas, can anyone help me out of this mini crisis of mine? (HowTos)
