I want to backup the ROM, in case I am fooling around and brick it. Is there a way to backup the ROM (or the TA partition, right?) without rooting the phone? I want to try the vanilla experience for a while. If not, what's the safe way to root without messing up the TA partition and losing the unique keys?
Also should I upgrade the ROM? Many people have complained about the phone getting slow after upgrading. Also, I read, in newer versions it becomes impossible to root without unlocking the bootloader, which will result in loss of DRM keys, removing some features.
Oh and some app recommendations would be nice too.
Is that McAfee app that comes preinstalled necessary?
Anyone tried encryption? Does it affect performance by a big factor?
I'm thinking of buying a transparent TPU case for the phone. Anyone knows where I can get one online?
Any other advice to a new owner is welcome too.
