i changed my bootanimation.zip with custom animation file, yet it was fine.
but when i tried to change framework_res.apk with a custom framework file and then i rebooted and from there the problem started.
It is not booting it just shows the bolt logo and then the custom animation that i loaded but then it shows a blank screen turns off and again starts. this process goes on and on till i turn off the mobile.
specs of my mobile:
1. gingerbread 2.3.5
2. 200mb ram
3. 1 ghz cortex a5 processor
