my step brother recently gave me a PSTV he claims has already been modded, but he didn't provide much instructions on how to use the homebrew and stuff. the PSTV is currently on firmware 3.60. it has molecularshell and vitashell installed (and antiblacklist which i'm assuming is homebrew) but they don't seem to launch, i just get "an error has occurred c1-6775-5" every time. and accessing the email app gives me a "this memory card email database must be formatted first" (or something like that) error. i skimmed through the guides already posted here but i don't know what point to start at, what needs to be installed, etc. i'm extremely new to pstvbrew and i don't want to format and start from the bottom in case of any potential damage any help would be greatly appreciated!
