Installing Adrenaline without PSN Access (Advanced users)
As most of you know, PSN spoofing no longer works but that doesn’t mean the end of the world for those that wish to play PSP games/homebrew on their PSVita. A well-written tutorial, some courage and a PSP are enough to get yourself Adrenaline by installing the smallest PSP demo available.
Fellow reddit user, doklo, has posted a guide on how to get Half-Minute Hero demo working on PSP (for US accounts) and WipeOut Demo (for EU accounts). In a nutshell, you get a license file by installing the game via the PSN download list on your PSP, you install Package Installer, the demo pkg and then copy the license file over to your Vita. Sounds simple, right?
Well, there’s a catch and here’s where you need quite a bit of courage and some experience with the PSVita. The catch is that you need to use IDU MODE, IDU mode or Demo mode is a mode that allows you to install certain packages and gives you more system options at the expense of messing something up. IDU mode also updates by itself so people who venture into it MUST TURN OFF WIFI ON THEIR VITA AND EVEN FORGET NETWORKS TO BE SAFE.
Another drawback of IDU mode is that initially, it’s locked in DEMO MODE, it’s quite easy to get out of this, you just need to hold “L,R,D-pad up and start”(L1, R1 as L,R on the PSTV) for a few seconds. The combination may not work immediately, do it a few times and it’ll work. Try not to panic. Another thing to note about DEMO mode is that if not connected to a power supply, the Vita shuts off after 5 minutes.
Make sure that you are using HENkaku r6 (stable) and that the Offline Installer is working properly in order to avoid any unnecessary issues. After installing the demo, just install Adrenaline: https://gist.github.com/TheOfficialFloW/0ed4e09e2d447e631416cb84d7c43107 If you’ve been living under a rock, Adrenaline is theFlow’s eCFW that runs via taiHEN and it allows you to run PSP backups/homebrew.
FOLLOW WITH CAUTION AND GOOD LUCK!
