Re: Do I lose everything by switching roms with unlocked bootload
Yes. Best practice is to wipe data everytime you switch to a different ROM, but not to different versions of the same ROM. However, before I change ROMs, I always make a back up in CWM incase I want to go back, returns the phone to the exact state you left it in before the new install.
Yes new ROMs normally do fix the tethering restraint, but I have been having issues with it on GPA 19 for some reason.
