PS Vita 3.65, 3.67 & 3.68 Firmware Jailbreak by TheFloW H-encore

For those with a PlayStation Vita handheld console still kicking around, you'll be pleased to know developer TheFloW just released h-encore, a fully chained kernel exploit for PS Vita on Firmware versions 3.65-3.68 which allows the loading of homebrew including HENkaku and the TaiHEN CFW Framework.

Below are the h-encore installation instructions from the README.md, to quote: h-encore

h-encore, where h stands for hacks and homebrews, is the second public jailbreak for the PS Vita™ which supports the newest firmwares 3.65, 3.67 and 3.68. It allows you to make kernel- and user-modifications, change the clock speed, install plugins, run homebrews and much more.

Requirements

Your device must be on firmware 3.65, 3.67 or 3.68. Any other is not supported. If you're on a lower firmware, please decide carefully to what firmware you want to update, then search for a trustable guide on /r/vitahacks (if you know how and want to contribute, you can edit this readme and make a pull request, such that fellow readers have got an easier life). Remember that on firmware 3.65 you have got the possibility to install enso, the permanent hack, whereas on 3.67 and 3.68 you don't.
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. Make sure you have got at least 270 MB of free space.
Your device must be linked to any PSN account (it doesn't need to be activated though).

Installation

Note that the following guide is for advanced users and a bit more complicated than the previous hack that only required you to visit a website. If you don't understand the guide below or how to use these tools, you should neither file an issue here nor annoy me on twitter, but rather seek help on /r/vitahacks (check for duplicated questions first!) or wait for an easy installer by somebody else.

1 - Download and install qcma, psvimgtools and pkg2zip (check the releases section).

2 - Download the vulnerable DRM-free demo of bitter smile (yes, that's the user entry point).

3 - Download h-encore and extract it on your computer.

4 - Extract the demo using:

Code: pkg2zip -x PATH_OF_PKG

This will output the files to app/PCSG90096.

5 - Copy the contents of the output app/PCSG90096 to the folder h-encore/app/ux0_temp_game_PCSG90096_app_PCSG90096 (such that the files eboot.bin and VITA_PATH.TXT are within the same folder).

6 - Copy the license file app/PCSG90096/sce_sys/package/temp.bin to the folder
h-encore/license/ux0_temp_game_PCSG90096_license_app_PCSG90096 and rename the just pasted file temp.bin to 6488b73b912a753a492e2714e9b38bc7.rif. Again, this file should be in the same folder as VITA_PATH.TXT.

7 - Start qcma and within the qcma settings set the option Use this version for updates to FW 0.00 (Always up-to-date).

8 - Launch Content Manager on your PS Vita and connect it to your computer, where you then need to select PC -> PS Vita System, and after that you select Applications. If you see an error message about System Software, you should simply reboot your device to solve it. This should create a folder at PS Vita/APP/xxxxxxxxxxxxxxxx on your computer (see qcma settings where this folder is), where the folder xxxxxxxxxxxxxxxx represents the AID (account ID) that you need to insert here. If the AID is valid, it will yield a key that you can now use to encrypt the demo.

9 - Change directory to the h-encore folder in terminal and use the key to encrypt all folders using:

Code:

psvimg-create -n app -K YOUR_KEY app PCSG90096/app
psvimg-create -n appmeta -K YOUR_KEY appmeta PCSG90096/appmeta
psvimg-create -n license -K YOUR_KEY license PCSG90096/license
psvimg-create -n savedata -K YOUR_KEY savedata PCSG90096/savedata

The folder h-encore/PCSG90096 should then contain sce_sys and all 4 folders from above, and within these folders you should find files called X.psvimg and X.psvmd, where X has the same name as the folder. Backup this folder, since if everything has been done correctly, you don't need to redo all the steps to install it onto another device with the same PSN account.

10 - Copy the folder h-encore/PCSG90096 to PS Vita/APP/xxxxxxxxxxxxxxxx/PCSG90096 and refresh the database under qcma settings.

11 - The h-encore bubble with a size of around 243 MB should now appear in the Content Manager and that's what you finally need to transfer to your PS Vita.

12 - Launch h-encore to exploit your device (if a message about trophies appears, simply click yes). The screen should first flash white, then purple, and finally open a menu called h-encore bootstrap menu where you can download VitaShell and install HENkaku.

13 - Enjoy. Note that you have to relaunch the exploit everytime you reboot or shutdown your device. Of course if you only put your device into standby mode, you don't need to relaunch.

Getting rid of the trophy warning

Since the savedata that I provided is not linked to your account id, launching h-encore would eventually show a warning message about trophies. To get rid of that you must do this on your PS Vita:

1. Enable Unsafe Homebrews under HENkaku Settings in the Settings application to grant VitaShell full permission.
2. Launch VitaShell and navigate to ux0:user/00/savedata/.
3. Press triangle on the folder PCSG90096 and select Open decrypted.
4. Copy system.dat out of the folder and remove the folder ux0:user/savedata/00/PCSG90096.
5. Close VitaShell and launch h-encore (this will now not trigger the exploit anymore, since we've removed the savedata).
6.Close the game after you see the first screen and return back to VitaShell.
7. A fresh folder of PCSG90096 at ux0:user/savedata/00 should have been created.
8. Copy system.dat back to ux0:user/savedata/00/PCSG90096/system.dat where you need to open the PCSG90096 using Open decrypted.
9. Now if you launch h-encore you should not see the trophy warning anymore and exploiting your device is therefore even faster.

FAQ

Exploit

"When I launch h-encore, it stays at a white screen." - Due to the nature of the kernel exploit, this can sometimes happen. If it stays white for more than 5 seconds, you can simply close the application which will result in a crash and your device will be rebooted or shutdown after 10 seconds. If it doesn't, hold the power button down for over 30 seconds to force a shutdown. Then try the exploit again. The success rate of the kernel exploit should be at 80%. If I find time I will eventually try to improve the success rate.
"When I launch h-encore, it flashes white quickly and then crashes." - Again, this is due to how the kernel exploit works.
"I get a C2-12828-1 error when launching h-encore" - This does sometimes (but very rarely) happen. Just retry the exploit.
"When I launch h-encore, it launches the bitter smile demo instead." - Your savedata is either corrupted or not installed correctly, please follow the installation guide above to reinstall it.
"I have installed a bad plugin and launching h-encore doesn't work anymore, what should I do?" - You can either reset taiHEN config.txt or skip plugins loading by holding the L trigger while exiting the h-encore bootstrap menu.

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 3.67 or 3.68?" - Not yet, since molecule's bootloader exploit has been patched there.
"Can I install enso on 3.65?" - Yes, you can use h-encore to hack your device and then install the permanent hack using this.

Compatibility

"Are Adrenaline/NoNpDrm/Download Enabler supported on 3.65/3.67/3.68?" - Yes, check them in my repositories.
"Can I use SD2VITA using this hack?" - Yes, I have made a pull request on gamecard-microsd that fixed the freeze when using it without enso. If you're using an other plugin and it freezes on exitting h-encore bootstrap menu, then there's the trick where you can simply press the PS Button and return back to finish the boot process.
"Can I use psvsd using this hack?" - It should, but I'm not sure, as I haven't tested it. If it doesn't, then the driver must be updated, but that's not my task.
"Does this work, does that work? Is this compatible, is that compatible?" - I don't know, and it is not my task to update these tools for you, so don't dare and file an issue here.

General

"Can I switch the PSN account after having h-encore installed?" - Yes, since the demo is DRM-free it does not depend on your account.
"Are there any risks involved in using h-encore?" - No, since it does not modify the OS, but only insert temporary patches into the system.
"Can I install it without USB connection?" - You can also connect your PS Vita with your computer using Wi-Fi (there's an option in the Content Manager).
