Trinity

Trinity is the third public jailbreak for the PS Vita™, which supports the latest firmwares 3.69 and 3.70. The exploit chain consists of three stages: the MIPS Kernel Exploit, the PSP Emulator Escape and the ARM Kernel Exploit.

Write-up

A technical explanation of the Trinity exploit chain is available here.

Requirements

Your device must be on firmware 3.69 or 3.70. If you're on a lower firmware, please use h-encore instead.
If your device is a phat OLED model, you need a Memory Card in order to install. There's no need for a Memory Card on Slim/PS TV models, since they already provide an Internal Storage.
Your device must be able to access the PlayStation Store.
If your device region is mainland China (model PCH-2009) then this exploit may not be available for you, since this model is region locked to only accept mainland China PSN accounts to login and can only access mainland China PS Store, which doesn't contain any PSP games at all.

Preparation

If you have already done the preparation, you can skip this part and go to the Installation section.

If you're on firmware 3.69, you have two options:
- Either update to firmware 3.70 (go to Settings → System Update).
- Or set DNS to 212.47.229.76 (go to Settings → Network → Wi-Fi Settings → Your access point → Advanced Settings and set DNS Settings to Manual and Primary DNS to 212.47.229.76).
Register a PSN account if you don't have one yet (note that only 3 devices can be activated using the same account).
Download and install any PSP/minis game (PS Vita or PS one Classics do not work). There are demos in most regions (if you know a title that is not listed here, please let me know):
- EU/UK: Ape Quest
- NA/SG: LocoRoco Midnight Carnival
- JP: YS seven
Unfortunately, if you can't find a demo in your region, you must either buy any PSP/minis game, or register a new PSN account in one of the regions listed above.
Please make sure that your demo is a PSP/minis game. To verify, please launch the game and hold the PS button for a while. Then a quick menu should come up with the Settings option, where you can set bilinear filter, etc. If this option is not there, you've likely downloaded the wrong game. For help, please consider watching some youtube tutorials and see how a PSP game should look like.

Installation

Download and install qcma and psvimgtools.
Start qcma and within the qcma settings set the option Use this version for updates to FW 0.00 (Always up-to-date) to spoof the System Software check.
Launch Content Manager on your PS Vita and connect it to your computer, where you then need to select PS Vita System -> PC, and after that you select Applications. Finally select PSP™/Other and click on the game that you want to turn into the Trinity exploit. If you see an error message about System Software, you should simply reboot your device to solve it (if this doesn't solve, then put your device into airplane mode and reboot). If this does still not work, then alternatively set DNS to 212.47.229.76 to block updates.
Transfer the game over to your computer by clicking on Copy on your PS Vita. After copying, you go to the folder /Documents/PS Vita/PGAME/xxxxxxxxxxxxxxxx/YYYYZZZZZ on your computer, where xxxxxxxxxxxxxxxx is some string corresponding to your account ID and YYYYZZZZZ is the title id of the game that you've just copied over. You can look at the image at YYYYZZZZZ/sce_sys/icon0.png to verify that it is indeed your chosen game. Furthermore, the YYYYZZZZZ folder should contain these folders: game, license and sce_sys.
Before you attempt to modify the backup, you should make a copy of it. Just copy YYYYZZZZZ somewhere else, such that if you fail to follow the instructions, you can copy it back and retry.
Insert the xxxxxxxxxxxxxxxx string here. If the AID is valid, it will yield a key that you can now use to decrypt/re-encrypt your game.
Decrypt the game backup by executing the following command in your command line/terminal (make sure you're in the right working directory. On Windows you can open the terminal in the current working directory by typing in cmd in the path bar of the file explorer. Also, if you haven't installed psvimgtools yet, then just place them in the YYYYZZZZZ folder):
```
psvimg-extract -K YOUR_KEY game/game.psvimg game_dec
```
If done correctly, you should see an output like this:
```
creating file ux0:pspemu/temp/game/PSP/GAME/YYYYZZZZZ/EBOOT.PBP (x bytes)...
creating file ux0:pspemu/temp/game/PSP/GAME/YYYYZZZZZ/__sce_ebootpbp (x bytes)... 
all done.
```
Download Trinity and copy the PBOOT.PBP file to game_dec/ux0_pspemu_temp_game_PSP_GAME_YYYYZZZZZ/PBOOT.PBP (the files EBOOT.PBP, __sce_ebootpbp and VITA_PATH.txt should exist in this folder). If PBOOT.PBP does already exist there, just overwrite it.

Now re-encrypt the backup similar to above by typing this in your command line/terminal:

psvimg-create -n game -K YOUR_KEY game_dec game

If done correctly, you should see an output like this:

adding files for ux0:pspemu/temp/game/PSP/GAME/YYYYZZZZZ
packing file ux0:pspemu/temp/game/PSP/GAME/YYYYZZZZZ/EBOOT.PBP (x bytes)...
packing file ux0:pspemu/temp/game/PSP/GAME/YYYYZZZZZ/PBOOT.PBP (x bytes)...
packing file ux0:pspemu/temp/game/PSP/GAME/YYYYZZZZZ/__sce_ebootpbp (x bytes)...
created game/game.psvimg (size: x, content size: x)
created game/game.psvmd

Remove the game_dec folder (and PSVimg tools if copied here) and select Refresh database in qcma settings.
Now you need to copy back the modified backup to your PS Vita: Launch Content Manager on your PS Vita and connect it to your computer (if it's already open, just go back to the first menu), where you then need to select PC -> PS Vita System, and after that you select Applications. Finally select PSP™/Other and click on the modified game. Perform the copy operation and exit Content Manager.
In the livearea, the game should now have a different icon and should now be called Trinity (eventually you have to rebuild the database in recovery mode to make the bubble change its look). If not, please re-read the instructions more carefully and begin from fresh.
Turn on Wi-Fi, then reboot your device and straightly launch Trinity. Do not do anything else, otherwise the exploit will be less reliable. It is very important that you do not have any running downloads in background.
Enjoy the exploitation process and wait until it launches the Construct. If the exploit fails, simply rerun Trinity.
Within the Construct, select Download VitaShell, then Install HENkaku and finally Exit.
Congratulations, your device is now able to run homebrews. It is highly suggested that you downgrade your device to either firmware 3.60 or 3.65/3.67/3.68 using modoru. On 3.60, you can use HENkaku and on 3.65/3.67/3.68 you can use h-encore. If you don't downgrade your device now, you may lose the ability to launch Trinity later and therefore not be able to hack your device anymore.

FAQ

Exploit

"I get the error [TURN ON WI-FI TO USE THIS EXPLOIT]." - Just hold the PS button and turn on Wi-Fi in the quickmenu.
"I get the error [EXPLOIT FAILED: 0x800200CB]." - This can sometimes happen. Just rerun the exploit.
"My device freezes/panics." - Be sure you do not have any downloads running in background. Also make sure that you do not launch anything else before Trinity. A fresh reboot is always recommended.
"Trinity crashes in the second run." - It is not recommended that you launch Trinity multiple times. Always reboot your device before launching Trinity.
"Trinity bubble disappeared after downgrading." - Sony prevents you from playing games that have been downloaded from a higher firmware. Therefore, after downgrading, it is hidden. You can redownload the game on your lower firmware and reapply the Trinity patch to make it compatible with your current firmware and higher.

HENkaku Settings

"I don't see all folders in VitaShell." - Launch the Settings application and select HENkaku Settings, then select Enable unsafe homebrews. This will grant you full permission in VitaShell.
"I can't find the HENkaku Settings." - Launch the exploit and reset taiHEN config.txt and reinstall HENkaku.

enso/permanent hack

"Can I install enso on 3.69 or 3.70?" - Not on these firmwares, but you can downgrade to firmware 3.60/3.65 using modoru and then install enso.
