Thanks again, @godreborn. All set now as far as my home menu issue.
I do have one other general question while I'm here, about DLC. When I first got started backing up and installing my games (with 9.00 - I'm a newcomer on the PS4 scene), I neglected to consider DLC when dumping my games. I mostly just assumped appdumper would include DLC in addition to the game and update, but that seems not to be the case. At this point, I've dumped, deleted, and reinstalled via FPKG just about all of my games.
At this point, is there any hope of recovering my DLC for those deleted games? or am I boned? I feel like I'd need to sign in and re-download everything from the PSN store to get it back, but I can't do that (as far as I'm aware) without updating firmware, and even if I could, I suspect there'd be some kind of mismatch between the APP FPKG and DLC PKG keys.
Like I said, though, very much a newcomer, so hoping I'm simply overlooking something...
