I am on 3.52 m33 v4, I want to stay there. I already have a pandora, have installed cemetrio v3 and the new Ultra Recovery Pandora Mode Extender Installer. All that I want is to be able to unbrick my phat 3.52 m33v4 if I need to to 1.5, and when I get a slim to unbrick it/upgrade it to 3.71 custom firmware. I want this on the same memory stick with the same pandora battery. Am I good to go or do I need to do something else?
