if I turn it off and disable rd mode how do I start it up again? won't it just go into the same black screen on reboot as before then. If not how do I disable the rd mode.... I'm not sure about what to do again.... I'm a bit unfamiliar about this remember.

I intend to flash my phone to stock and send it for repairs, hopefully they just switch the whole phone cause I will also complain about the screen being a bit buggy which it is. sometimes I have to let screen go black 3 times before slide open works (since I cant use powerbutton I have to wait for it to go dark before next attempt)
