Well I'm a little over 24 hours after using this method to update and I have zero issues thus far everything seems smooth and I thought the battery was draining a little fast aswell but it's most likely me since I haven't put my phone down yet
Ok stupid question #2 lol I got a SD card today moved file to it renamed it before moving it but can't seem to find it when I go into reboot mode and hit apply update from SD card
