Hi there, i got a similar problem. My vita was acting up lately and a lot of stuff started crashing or wasnt working right. VSH for example didnt do anything besides showing fps anymore. I did a system restore since thats what everybody recommends. Somehow my memory card 64gig didnt get unlinked from my vita though... Now im stuck with a 3.65 vita with enso perma installed but inactive and i cant use my 64gig memory card anymore since i cant login without updating to make it work again. So my question is, can i somehow salvage this mess with my old 8gig empty memory card? Can i use qcma and somehow use that card to install henkaku/make enso work again? I have no clue what do, help would be greatly appreciated.
The crashes and stuff was most likely due to plugin conflicts or config.txt errors,
System restore does not touch the mem card unless you choose to format it during the restore process. It also does not remove enso, and if you left spoofing turned on before the restore that will also give you some issues.
You're best bet of recovering would be using your spare mem card to install h-encore, hopefully you backed it up in qcma, if not you'll have to reinstall it through the pc app, then you can coose to continue as is, or use modoru to reinstall your current firmware so you get a clean slate, either way you'll need h-encore and enso, as well as vitashell.
Then you're going to need to download these 2 apps
Then you'll need to use app manager plus to move cardunlock to ur0 partition so it will work even without a mem card inserted, you can also move vitashell if you want.
Once that's done just turn off vita and restart but with no mem card inserted, run cardunlock app, and while cardunlock app is running insert your locked mem card and follow in app instructions, just be sure that when you get a dialog pop up you always select NO, if you select yes you will format your mem card.
