Dude... That brings back bad memory as everyone should always do backup regardless of how much they know even for a pro like me I flashed custom kernel and baaaaaaam things went wrong as CWM2.1.5.2 won't update, sdcard turned -ro and unable to change it as PBS was corrupted in device, ooh ya the kernel had to abandon it after doing tests for 2days and flashed it like 40times or so. So I just got back to where I was 2days ago lol I wish I had done backup...
