Enso I started my journey.

  I decided to trade my new3DSXL for someone’s PSvita slim on a game trading website (gametz.com). It was a bit bittersweet to let go of an old friend, but I haven’t really gamed on it for a long time. So I thought I’d give the PSvita a go. Thus, my journey to modify my new old PSvita slim from 3.70 to 3.65enso.

  Modifying a 3.70 original firmware (OFW) has not been possible until lately when theFlow released the Trinity hack. The hack uses a vulnerability in the PSP emulation. It basically uses an official PSP demo found on the PSN store, mess with the files within, then converts it into the Trinity hack. This allows the henkaku and VitaShell to be installed on the PSvita with a 3.70 OFW.

  In order to get the Trinity hack working. I had to go install serveral things on my computer and on the PSvita itself. This was the easy part. Thanks to this guide: https://psvitamod.com/trinity-hack-for-3-69-3-70/. After that was working, it was time to install modoru using this guide: https://psvitamod.com/modoru-downgrade-the-ps-vita/. This package downgrades the PSvita from 3.70 OFW to 3.65 OFW or other firmware of your choosing.

3.65 OFW! AWWW YEAAH! Now all I need to do is open VitaShell to activate henkaku again and install enso. WROOOOONG!!! The downgrade actually affected the install of VitaShell, which means I need to redo my installation of it. So I treated this part as if I’m just modifying a fresh 3.65 OFW PSvita from scratch.

Following the README file from theFlow’s official h-encore repository got me there (https://github.com/TheOfficialFloW/h-encore). This made my VitaShell usable again. So I just transferred the enso.vpk from my computer to the PSvita. This is the one I used: https://github.com/TheOfficialFloW/enso/releases/tag/v1.1 . I got caught with some errors initally with this because the link I downloaded from was for 3.60 OFW. >__O So make sure you’re downloading the right/compatible version!

Installing the package will grant you the coveted 3.65enso custom firmware (CFW). Now the real fun begins! :D
