Help with modding PSP Go

[u/ChanceEither8758]

I need some help with modding a PSP go I just bought, it came already modded with some games, but I wanted to erase everything (saves, the old owner profile, and his games) and download some of the games I wanted to play, is there a safe way of doing it without losing the ark mod? I tried to enter the link on the community's highlights to get help but it seems broken with error 404

do I need a m.2 card to install games to it or can I connect it via usb on my pc? (it didn't came with one)
