    My PSP Go is version 6.60, I upgraded from 6.37. Can't seem to downgrade to 6.20 as I get that error message. I want 6.20 b/c of its permanent custom firmware, regardless of the 5 second wait I'd usually have to deal with. Could someone link me the downgrader and firmware needed for this? I've been at this for hours.

    I thought there was a way to get 6.60 permanent?

    Not on a psp go. It only works on a psp 1000/2000.


    Rydian's full guide here

    All of the links are provided within the spoiler (downgrader + 6.20 ofw for go), as well as instructions. Note the part "For the Go it needs to be on the internal flash, not the M2 card" and make sure you put the files in the correct place.

    Just a note, all Go's come with 5.70 stock (those with higher firmwares were simply updated for obvious reasons), so you don't have to worry if it can be downgraded or not.
