You can re establish root just flash older ftf and Start over its easy. You can unlock but not alot of custom roms and stock seems to run pretty good for me if you do unlock make sure to.backup ta for.Bravia engine and drm so if you go back to stock you can restore ta
Personally I'm on stock and it.runs great
