After installing cyanogenmod 10.1 it reversed my internal storage with my ext storage so that when I tried to flash the latest nightly build it could not find the backup i had made. Now it wont let me activate my phone because it cant get a vzw signal. I tried to copy the files over to both the ext and internal unsure of which is which but it still wont let me activate my phone. It will let me flash the roms and gapps but i cant get a signal. the storage is all messed up and im wondering if theres a way to just factory reset the storage and start from scratch?
