view story

http://forum.xda-developers.com – So I flashed many things including changing boot animation and autoflash franco kernel, and rebooted, google boot text shows. So it's not hardware problem. But then screen went blank after that, including boot animation. I know the phone has booted because Windows can browse its file system, it receives called (ringtone), and I feel the vibration feedback when I touch it for example I feel the unlock vibration. The screen is 0% somehow and I can't adjust it without seeing the UI. ADB is not yet turned on. Please help me!!!! How do I get brightness up again? I'm on AOKP (HowTos)
