I tried to instal jelly bean (Android 4.1.2 AOKP Milestone 1 Jelly Bean) after 3-5 mins my phone just went blank. at first i thought the screen timedout. but then it didn't work, and still doesn't. Since nothing has popped up on the screen. I took the sd card and my sim card out, and put it on charge. Help me im going to cry.
