I am on stable android pie. Does flashing developer preview beta 3 or this rom wipe my internal storage?
Yes it will wipe internal, you must back up.
I was reading that I should format data, but if I format data that will wipe my internal storage & twrp doesn't let me transfer files. How do I install the Rom if I format the data? My files will be erased
