Hacking C2-12828-1 error loading any system apps

[Skulldize]

Hello guys!

I was researching my problem for the last few hours but couldn't find anything that fits my problem, so I hope somebody here has any solution.

Well, yesterday I basically followed the tutorial from vita.hacks.guide. Everything went smooth there, no problems. After that I installed Adrenaline and even that worked fine until I noticed that my system apps like Settings or Webbrowser are crashing with a C2-12828-1 error. Then I started Adrenaline and the error also occured there. This followed through to other apps, so my Vita was basically non-functioning.

After this whole mess, I reformatted the memory card and restored the system. Then I reinstalled everything except of adrenaline. Everything was working fine until this point until I put Adrenaline on the Vita again. Now, nearly every system app is crashing with C2-12828-1 but the homebrew apps like VitaShell or Adrenaline are running fine. Playing PSP and PSX Games also works without any problems.

It seems that Adrenaline is the problem, because everything works fine before installing it but I can't get behind the reason what exactly the problem is.

Help is much appreciated, I'm really desperate here. Thanks!

I've tried this without any luck but I already saved my problem.

It seems it had something to do with the PSN connection. I resetted my system to the OFW 3.6 and did the whole CFW installation again. This time I tried the Adrenaline easyinstaller, which advised me to activate my Vita, which the normal Adrenaline didnt do. Then I logged into PSN, tried the easyinstaller again and it worked. Until now everything works fine, I hope it stays that way.
