Vita downgrader
modoru is a PS Vita firmware downgrader that lets you roll back to an earlier firmware — primarily so you can reach 3.60/3.65 and install the ensō permanent exploit. It wraps the official Sony updater with a few patches to bypass direction checks, which is why it doesn't brick. Audience is Vita hackers who bought hardware with a newer factory firmware and want persistent CFW.
Uses the official Sony updater internally rather than a custom flash routine, which is why brick risk is low. The factory firmware floor is enforced and highlighted in the UI, so users can't accidentally lock themselves out. Codebase is small and readable C — kernel module, user module, patch module, SPKG parsing — nothing bloated. TheOfficialFloW has a track record in the Vita scene (HENkaku co-author), so the primitives it depends on are well-vetted.
Last commit was January 2023 and the Vita hacking scene has largely moved on, so don't expect updates if Sony or community tooling shifts. No automated tests — it's a homebrew VPK you flash to a console and hope for the best. The setup ritual (rename tai folders, source your own PUP file, 50% battery minimum) will trip up anyone not already deep in the Vita community. No recovery path documented if something does go wrong mid-flash; 'not likely to brick' is not the same as 'impossible to brick'.
