PS Vita Firmware 3.65 is making its way to the regular update channels. It is unclear at this point what the firmware changes.
PS Vita 3.65 firmware patches ARK ePSP Custom Firmware
Team molecule recently released a way to access the PSN from HENkaku enabled consoles, running on firmware 3.60. It was revealed that Team molecule were able to get access to the 3.63 passphrase, and with it, a HENKaku 3.60 console could act as a 3.63 to get access to the PSN and other Sony service.
It wouldn’t be surprising if PS Vita firmware 3.65 changes the passphrase, meaning HENkaku users will most likely lose PSN access once again. The question will then be to see if Team molecule can reproduce their stunt an give back PSN access, for example if Sony only changed the passphrase, or if the update is deeper than that.
All of the above is just speculation at the moment, as nothing has been confirmed on the scene side, and the official PS Vita 3.65 changelog still needs to be disclosed by Sony.
There is some good news… it seems that just like before Sony left the VHBL, Emulator bubbles, Custom Themes, and the PSTV Whitelist hax ver:2 alone because they are all still working just fine on FW 3.65 but the sad news is Ark does not work on FW3.65.
