DONT FOGET TO SAY THANKS TO Mecss the script cleans the left over files of a kernel, to prevent issues or compatibility problems when switching between kernel, kinda like Ccleaner for win it does a cache wipe / dalvik wipe and a few other steps, basically it does the job for you, no need to manually do those tasks INSTALL NOTES - Place the zip file in your internal SDCARD - Flash it as a normal package from ClockworkMOD recovery - Flash any kernel - Reboot
