Q: Can I downgrade my Vita?
A: Yes, but only if the console is already on a hackable firmware. Modoru can downgrade any system hacked with HENkaku or H-Encore to any firmware equal or greater than the firmware the console came with out of the box.
Q: Is it safe to update a Vita with CFW?
A: No! You must always ensure that you have blocked updates as specified at the end of Finalizing Setup.
Q: Now that Sony has ended production of the Vita, does that mean no more updates will be released?
A: This is not necessarily the case. The firmware version 3.68 was released six months after the previous update (at which point it was assumed no new updates would be released).
Q: Where should I go for support?
A: For support, ask for help at Vita Hacking on Discord.
