Hi, so the curiosity got the best of me and I rooted my Ultra and flashed PAC MAN Rom, only to find out I acually prefered the stock rom. Noob as I am, I'm not sure now how to proceed in getting it back. I'd like to go back to 14.2.A.1.136 stock rom. How does one go on about that? Is it ok to use flashtool and flash 14.2.A.1.136 "Generic GM" ROM that I found online back in? /I'm in UK, but couldn't find any other european version than GM - Germany/. I'm on Z Ultra C6833, rooted with unlocked boot loader. Thanks for advice!
