I flashed my xperia t (using flashtool) with a stock firmware 4.3 that had cwm6.0.4 already with it. Then from the cm update options in settings i updated it to latest version of cm11 Nightly (20140430). I had also flashed gapps for 4.4 kit kat. Everything was working fine, but then it crashed with a blue screen and rebooted. Then it happened again and again like every 20/30 minutes. Last time it has happened, i was trying to change my background and the blue screen came up and rebooted. Does anybody know what the problem might be? I greatly appreciate your help.
