Ok so I'm trying to get the stupid menu button from unlocking my lockscreen and I've tried 2-3 different zip's from different bases and none are working, but how do I unflash them and remove them from my current setup..?? Even though nothing is working I just don't want a buncha random clutter flashed to my phone if it's not even doing what I want..

Also, once we flash a zip, is there any way to revert without performing a backup..??

(Example: I remove the HTCLockscreen and installed the AOSP Hero Lockscreen, but if I can't get the menu button to stop unlocking I wanna go back to the original HTCLockscreen, possible..?)
