v5.3.1
(Reuploaded because I screwed up)
- Fixed NANDs with partial background updates using the new FIRM.
Please note I need testing with this change, as it might cause issues for Old 3DSes which used the Gateway launcher to downgrade the console in the past. I have verified this is probably not an issue as all the leftovers seem to be deleted after an update, but I'm still not 100% sure. If you notice a regression (Luma failing to boot) I'd like to know.
