Argh, I think I spoke too soon. When Adrenaline launches, I get error C0-9252-8 and it crashes to home. Resetting and rebuilding database haven't fixed it. Next to nothing on Google about this error too.. Any ideas?

Steps

Step 1: Install QCMA, FileZilla, DB Browser on ur PC. Place the package file in the designated qcma package folder. Default is Documents/PSV Packages

Step 3: Reboot your Vita, install taiHen again, and open VitaShell to gain access to all files.
Step 4: Start an FTP server, and place 661.PBP in ux0:/pspemu/adrenaline
Step 5: Go to ux0:/license/app/VITASHELL and download the license file to your PC

Step 11: Upon replacing app.db reboot the system and start up taihenkaku.
Step 12: If you haven't done so already, link ur Vita/PSTV to QCMA. Then launch the IDU app and enable idu mode. Disconnect from the internet and reboot. This is a must or it will attempt to auto update.

Step 18: Install taiHen and boot Adrenaline. It should boot assuming everything went smoothly.
Step 19: Enjoy

If anybody wants to rewrite this feel free. I pieced together various info from several guides and don't really feel like doing it all proper like. This removes the need of PSP/PS3 so should help anyone who missed the PSN Deadline.

Update: There is now a more convenient way to keep your vita from updating while in idu mode. It also makes it convenient to upgrade directly to 3.60 from any firmware below it. You can find more info here: http://wololo.net/2016/12/03/henkaku-update-server-easy-way-update-ps-vita-fw-3-60/

 

Mine is activated but you said it did work at least once right and the error is no longer an activation error? perhaps something became corrupted?

 

I did find some info regarding that error. It is possible the game iss imply not compatible with adrenaline for w/e reason. it might be fixable but finding or using a different game might resolve the issue. this error occured with vhbl stuff it seems and some games just dont cooperate. im using the one found here which you might have missed. http://zeus.dl.playstation.net/cdn/...GS2kHjqiIFYGw3BLuEXbwX6I1YQGJHNuF3n2UqMpT.pkg

 

Actually that's the same one I tried - Half-Minute Hero demo (6.9MB) (from the reddit IDU thread)

Good thinking - I'll go back and try the OP's pkg and one or two others via IDU.

 

Mine is activated so I'm wondering if that's the issue people are having.i am at work at the minute so cant test stuff. If I get a chance to night I am going to have a look at the ACT.DAT file and see if it can be opened and subsequently spoofed (everyone on unactivated has been able to install taihen so we have file access - it may have to use VITA-RW but its worth a look)

 

If anyone wants to get a head start and has an activated VITA.

The ACT.DAT is located tm0:npdrm/act.dat

DONT DELETE OR ALTER IT without a backup else you may be screwed.

 

No bubble icon, not work!

 

If an unactivated vita is one of the suspected factor that make this method impossible, why not activating it to have one less worry? Speaking for myself I have an unactivated vita, been trying to activate it, there are some methods out there to activate it, but I have no success, there's this vita activator vpk that I use but it gives me an error saying IDPS is invalid, then there's this website that you can enter your PSN account info and IDPS number so that it can connect to the Sony website and fetch your act.dat for you, that hasn't work for me either.

 

Incorrect. I replaced the files and pointed a bubble to it. It did not launch unless i was in idu mode. Don't spread false information. I tested it myself. Hence why i bothered writing my steps at all.
