Flash boot.IMG without PC and s-on
I take no credit for this information.
Extract boot.IMG from ROM.
Place boot.IMG on root of sdcard.
Open Terminal emulator and enter.
dd if=/sdcard/boot.img of=/dev/block/mmcblk0p21
Reboot to recovery, wipe, and flash.

Searching is easy. Making people angry that you didn't search is even easier. Use XDA on browser if you have trouble searching.
