Troubleshooting after Rebooting:
First step, when experiencing issues flashing is to RE FLASH the files again. Many times, re flashing again will clear up any issues. If not, see the issues/solutions below.
Issue #1: If the device hangs or reboots while on the splash screen, the kernel (or packaged ramdisk in the kernel) is NOT compatible with your device!!!
Solution for #1: Have to boot into fastboot and load the custom recovery to flash a known good kernel or restore a previously known good nandroid backup. Command: fastboot boot c:\downloads\cwm-recovery.img
Issue #2: If the device hangs or reboots while on the boot animation, the ROM is likely NOT compatible with the kernel!!!
Solution for #2: Have to boot into fastboot and load the custom recovery to flash a known good ROM/kernel combination either from a zip file or restore from a nandroid backup.
