I attempted to update using the OFW and apparently its not possible since it reads "you have 9.90 and do not need to update". Well, that's a relief as apparently it is a typo in the version.txt so I'll need to modify that.
Edit: Alright, got up to OFW 6.61 then loaded the 6.61 CFW with the IPL flasher and we're good to go. Still able to access PSN without issue and the ability to change between OFW/CFW is a nice change.
