ARK 2 eCFW v11 jusqu'en 3.36

Start Hot Brain > Load Game > load save > Multiplayer

Transfer the save in the "PSP" folder to your hacked PSP/Vita/PSTV,
so the folder layout should look like this:
ms0:/PSP/SAVEDATA/NPUH10091SLOT00/

Transfer the save in the "Vita" folder to your "unhacked" Vita/PSTV.

Transfer the php_adhoc_exploit.prx to your hacked PSP/Vita/PSTV to ms0:/seplugins/.

If you are using a PSP or TN-V on the hacked Vita/PSTV then make a file called ms0:/seplugins/game.txt,
place this inside it,

ms0:/seplugins/php_adhoc_exploit.prx 1

Make sure the the plugin is at the path pointed to in game.txt.

If you are using ARK then make a file called PLUGINS.TXT inside the ARK save folder.
place this inside it,

game,ms0:/seplugins/php_adhoc_exploit.prx,1

Make sure that the plugin is at the path pointed to in PLUGINS.TXT.

Once you have everything done as stated above, launch the game on both the hacked and unhacked devices.
On the hacked PSP/Vita/PSTV, start multiplayer with "Create Game".
On the unhacked Vita/PSTV, start multiplayer with "Join Game".

It should take a few seconds for the exploit to work,
if it doesn't work then make sure you have Wi-Fi enabled and flight mode disabled on the Vita/PSTV,
you do NOT need to be connected to an access point for it to work.

If you do not want to use the provided menu (Pro Shell), then you can replace it with another menu by switching out EBOOT.PBP.

If it crashes before anything flashes the screen, try this method posted by @trakons (https://twitter.com/trakons/status/586102514598150144)
"sorry I correct my tweet, you must enter and exit to the airplane mode and exploit work every time on 3.50 EU"

Here is a youtube video tutorial by @trakons for those having the issue with the exploit crashing.
