Long story short. Went from PA3.68 to Mmuzy 4.3. Everything worked booted and was installing apps. After a reboot the system froze at Google screen (with unlock symbol) After a few battery pulls and a couple of tries at reinstalling 4.3 ROM, decided to go back to 4.2.2 PA. First tried a Nandroid restore...same issue of freezing at Google screen. Lastly have done factory reset(for 4th time) and reinstall of 4.2.2 pa3.68 and PA Gapps. Same issue, phone will not move past Google boot screen.
