First thing I'd try is a battery pull and reboot. If it still loops, I'd boot into recovery and wipe data and reinstall gapps.Then boot again. If it still loops, I'd boot into recovery and wipe system and data. Then reinstall the ROM and gapps.
Also installed Gummy flawlessly. Then went back to "restore data" and am now stuck on "Gummy" with dots beneath. Been this way7 a long time. Did batter pull several times with no change. Tried to boot into Recovery (Vol down + Power) and get START arrow and Android and beneath it "Downloading". Tiny red letters in upper left that I think say "Odin Mode." Any suggestions would be greatly appreciated,
Thanks for the response. I was able to figure that out finally. Went through several re-installs, etc. and "discovered" that after re-installing gummy zip and gapps and rebooting if I then tried to restore data I would get that freeze again. If there a way to restore data after installing a new ROM?
