We recently published an article about veteran PSVita developer TheFl0w teasing a release for the 3.65 HENkaku Ensō Updater by adding support to the 3.65 firmware of the console for the new version of Download Enabler v4.
As it turns out, TheFl0w has just released the 3.65 HENkaku Ensō Updater, which is very good news for anyone who's been waiting to play all the games that were released on 3.61-3.65 firmware.
Unfortunately, this update does not allow you to hack your console if your firmware is past 3.60, as you need to be on said firmware to use the homebrew enabler.
You also will not be able to downgrade your console back to 3.60 once HENkaku 3.65 is installed, so don't make too much of a rushed decision before installing the software. It's also worth noting that some plugins created for earlier versions may not work and would need to be ported to the new HENkaku before usage. Another possible sacrifice is that you can also lose the ability to run homebrews if you modify the OS or mess around with the partitions, and therefore have to reinstall the firmware. If you're just a regular user, this should however not happen if you're not planning on installing applications that modify some of the console's partitions.
You can check out the installation instructions from the project's GitHub page.
TheFl0w also reassures anyone who's still on software 3.65/3.67 by saying that he is working on an exploit chain and that it should be released by the end of this year. We'll just have to be patient!
