So no one makes the same mistake, can you explain how to delete a rom slot.

When you have ROM slots and you'd like to delete one or more of them, it's simple:
You must choose a ROM slot such as the stock one and make it active meaning the one you wish to delete
cannot be active. So if you only have Slot 1 in use and you decide to delete it completely, you need to make the stock ROM active, then go back to the list of slots, select the one you wish to delete (now that the stock ROM is active) and the Delete button will be available as an option. Press that and the ROM you're looking at will be deleted in a second flat (the slot will be deleted removing the partition for it, etc, but it happens very very fast).
So far it's nice - it's very nice actually - that Hashcode has put some blocks into place in this version of Safestrap: we can't install a ROM directly to the stock ROM spot (the device itself), and we can't obviously delete that as well. I made a booboo earlier that surely would have bricked my GS4A if it weren't for those blocks Hashcode has in place so, more thanks his way for saving us from ourselves with this tinkering and the usual Murphy's Law style stuff and mistakes we all make from time to time.
tl;dr find the ROM slot you want deleted, then make another one active, go into the one you want deleted (with another one active) and the Delete button will be an option. Can't delete the active one so you have to choose at least the stock ROM to be active - and no you can't delete the stock ROM thankfully.
That should cover it.
