i updated mi SGS 2 to LPQ and i have those three problems.
the first thing i see is i dont get the welcome screen, i dont care this screen, but i get it as a symptom of my problem.
the second thing and the most bothering is that i cant get the lockscreen.
and the last thing is that when i press the lock button instead of showing the shutdown menu it shutdown.
i know this problems where present in the betas, but i flashed today a phone of a friend y he doesnt have any of these problems.
does anybody knows someway to fix this?
