Also you need to change your primary DNS settings on your vita wifi to
212.47.229.76 to manually download the 3.60 firmware directly from a specific server. You can't use the official one and if you try, Sony might stealth update your firmware all the way.....at least thats what i've been told happens lol

so once you get the right firmware message as seen above go ahead and upgrade.
Then install HENkaku
http://henkaku.xyz/
To install it simply type this >
https://henkaku.xyz in your vita's browser and it'll take over from there and it should install MoleculeShell automatically. Sometimes you might get a certain error. if so shut it off and try again. Eventually you'll get it. Also once you have MoleculeShell installed, you can reinstall HENkaku much quicker and easier right from the main menu.
What MoleculeShell is, is what you will use to transfer .vpk installation files using a FTP client like filezilla to the Vita memory card. There are 2 .vpk files you need. VitaShell and Adrenaline but more on that later.
in MoleculeShell go to Henkaku settings and turn on allow unsafe mode so you can start installing stuff. Then scroll down to reboot.
reinstall moleculeshell and launch. Once in, press select. it'll enter ftp mode and show an IP address. Plug that address into your FTP application and connect to the Vita.
then get VitaShell.vpk file
https://github.com/TheOfficialFloW/VitaShell/releases/tag/1.61
copy it to the ux0 folder on the Vita using FTP. Then on the Vita, click it and it ask to install. Go ahead and do so.
Now that you have VitaShell you can plug in your vita to a computer and it'll read it as a removable device. It works a lot like Molecule except pressing select triggers USB mode instead of FTP mode. You should be able to see most of your folders on your computer. Unfortunately the ones you need are hidden so you have to go to your folder options in PC's Control Panel > File Explorer Options and set it to show hidden files.

should look like that. Now you should have full access.
Thats it for now. I'll post the rest (mainly how to install Adrenaline) below if you want. Or if you have any questions let me know.
