/* Troubleshooting */
Not booting?
If you don't get passed on "Samsung" white logo, your device is not supported. If you think it should be supported, report to the developer.
Terrible speed or battery life?
Battery life is more likely to be affected by applications. Review your installed applications. Customize the kernel settings to get the most out of it. Trickster MOD is recommended.
Random shutdown?
Attach log(/proc/last_kmsg) or it didn't happened!
