I am selling one of my Touchpads and I want to remove both the Cyanogen and AOKP ROMs from the device and reinstall Cyanogen. I want to be absolutely sure none of my personal data remains. I already performed a factory reset of WebOS and that comes up in the startup screen as expected. Using TWRP I did a factory reset of the device, but now just AOKP comes up even if I choose Cyanogen in the boot menu. At this point I don't want to burn a bunch of calories trying to figure this out - I just want to blow AOKP off the device and reinstall a fresh version of Cyanogen for the new owner. Thanks in advance!
