Hey guys, I have been using ebookapps for a long time on my old but holding 505, but got bored of constant crashes and wanted to see how PRS+ goes and woah, I'm impressed

However, I have troubles installing it... I managed to remove ebookapps, but can't install 2.0.14, the first time install completed okay, but file browser's name is "NODE_BROWSE_FOLDERS", games are "NODE_GAMES_AND_UTILS", and prs settings are all mess of "invalid type" and stuff. I then formatted internal memory and loaded again - this time there were errors during the "checking" phase after PRS install, device restarted and same view. I reloaded original sony firmware, which wiped PRS+ clean, then reloaded it again, same story, am I missing something? Or I need some prev version of PRS+ installed so I can upgrade to 2.0.14?
Thanks
Edit: reflashed sony firmware again, formatted internal memory again, installed 2.0.14 again - this time no errors on log, yet, NODE_BROWSE_FOLDERS and all the other stuff is there, this last beta very much looks like it have to be installed over something.
