I have been reading in several threads and I think I understand this correctly but I wanted to verify it. I have safe strap installed. I am on a 4.3 rom and the custom rom I want to install is also 4.3. I would like to make the custom rom my primary rom and get rid of the partition limitations. In order to do this I can wipe the stock rom slot and install it there, correct? If I make a nandroid back up of the original rom before I wipe it, I should be able to just restore that rom if I wanted to later, correct?
