Yup, all my stuff is update proof
.
On the other hand, doing a factory reset *without* uninstalling stuff before is *never* a good idea (unless you don't have any other choices), and may lead to head-scratching issues like ganburigan is experiencing... (That you'll have to fix by manually restoring the wiped parts of the hacks in the userstore: in the case on my stuff, pull the link* folders from the zip files and plop them in the userstore, then reboot).
