Yesterday, I've tried to download SAO Hollow Realization which is 3.61+, downloaded the comp packs but it's not working. It gives me the error "C1-6703-6" while trying to launch it. I've tried pretty much anything, included removing ref00d, removing the comp packs with ref00d active, downloading it from NPS or PKGj, but nothing... What can I do?!
I guys i solved yesterday this problem, i'm not so good with english but i will try to explain how do.
My ps vita is modded with enso(permanent) and firmware 3.65 in my ps vita there was nonpdrm for pkgj and i don't removed it, so unistal ref00d with auto plugin if you have them installed then try to instal them another time ever with autoplugin, you can't install this plug in ux0 but only in ur0 then install this plug in in ur0.
After this ref00d still not working then go to vitashell and ux0:tai/config.txt you need to edit this under the voice "KERNEL" there is ur0:tai/nonpdrm.skprx
under this you need to insert a line that will be "ur0:tai/reF00D.skprx" then restart your ps vita and play what you want.[/QUOTE]
**Correction** you need to edit ur0:tai/config.txt (not the ux0:tai/config.txt just delete it or rename it to something else, it messes with the other file)
I had a similar issue with another game that required 3.60+ and I was on 3.60 but reFood wasn't working for me. Since I was manually installing reFood, I had to switch to autoplugin, installed all the plugins I had before with autoplugin, the file in ux0:tai/config.txt should be deleted because reFood uses the file in ur0:tai/config.txt (so I just renamed the ux0:tai/config.txt to something else just to be on the same side and later on deleted all the plugin files that I had manually installed), restarted the console and voila, reFood was working now. Never faced any other issues after that with running 3.60+ games.
