I followed the tut on how to install 2.3 on my kyros mid 7015 and I was wondering if anyone new how to reset it back to factory reset as I don't have Clockwork mod on the device.
if you want to go back to 2.1 you have to reimage it again. there's a thread on how to do it here. if you want to do a factory reset, just go to settings/privacy... i would highly suggest you install clockwork mod and make a backup just in case things get screwed up!
