I've been using clean rom forever and I love it however my GPS recently quit working which was always a bug. Anyway I've been out of the loop for awhile and I can't find exactly what I need to update to the new roms I'm looking to start with a touchwiz one for now if it matters.
What all do I need to flash before flashing the rom? Also any suggestions on a rom that I can just leave I prefer something I can just leave and not update thanks in advance for any help.
