TheFlow, a very well-known developer in the PSVita’s hacking scene, has just released a pre-hacked version of firmware 3.65. However, not all PSVita’s between 3.60 to 3.65 can install the hack as it requires the PSVita to be on firmware 3.60.

There are also requirements. TheFlow’s 3.65 Updater is compatible with all the 3 PSVita devices: the fat PS Vita 1000, the slim PS Vita 2000 and the pocket-sized PS (Vita) TV so long as they meet the requirements:

It cannot be used on a device that runs firmwares 3.61, 3.63, 3.65 or 3.67 and there is currently no known way to downgrade a PS Vita’s system software. Additionally, HENkaku Ensō can’t be installed on any firmware that is older than version 3.60, but devices that are running those older firmwares can be manually upgraded to firmware 3.60. You also need to have/install VitaShell version 1.82 (or newer) before you attempt to update your device from 3.60 HENkaku to 3.65 HENkaku Ensō, otherwise a few problems will pop up.

Most of the plugins that were available on 3.60 HENkaku won’t work yet since they need to be ported over but the games should work fine and some have reported in Reddit that they didn’t work at first but they just deleted and reinstalled them to get them to work.

Of course, using this hack is clearly wrong and Sony will probably have this patched up soon unless they have completely given up on ever patching the PSVita.
