I'm on safe side icsleak 232 safe strap 2.0 and when I go back to unsafe side to load the stock rom the boot screen is messed up like the pic is scrambled so the system is messed up too the first time I fxz to 902 did it all over well it did it again and I kinda don't wanna do all that again anyone have this issue. And the reason I Ned to switch back is I need Bluetooth and audio is funky on liquid
