Hacking Vita Memory Cards Locked to latest firmware?

[vergil]

I have a 32gb vita memory card which i used as my main card (used it on FW 3.61) untill i got a 64gb. Now when i use the 32gb card on a second vita (3.60) it says i have to update the software in order to use it. I'm trying to install henkaku but having no luck(it gets the to black screen installs henkaku and then get a message in red saying henkaku failed to install). Anyway around this without formatting the 32gb card since i have all my games on it. Both vita's are linked to the same account

There's afaik, no way around it.

iirc, once you used a memory card on [firmwareVersion], it is not possible to use it on any older fw, unfortunately.

Nothing you can do unless you can get an exploit working, and even then it may not be possible to write to that part of the memory card without kernel access.

Unslaving it (deleting id.dat from the ux0: partition) works.

did i misunderstand, using idu mode, it will bypass the id.dat thing?
and you can enable idu via henkaku.

yeah but you can't do that if the card won't be read by the hacked vita... (or am i misunderstanding something here?)

possible without kernel access, we could do it via failmail and stuff like that, that didn't give us kernel access.

I haven't tried that, but it's reportedly the case. Worth a shot but remember to be careful about autoupdates.

ok then, that is the solution idu/(demo?) mode.

(it takes time to read lots of the 'news' but it comes in handy when people need help!)


just make sure wifi is off, no wifi connection possible etc, because it tries to update, whatever, read about it. not dangerous if you take care.

Thanks guys, following cearp's solution, I've got the 32gb memory card working on my 2nd vita
