    error SGT 900000001 when trying to update

    I have (2) psp2000 with firmware 5.50 Prom4. Already edited the text so I can update to a higher firmware. I was able to successfully update one of them but when I tried to update the other psp to 6.20 or any higher CFW or OFW, I get the error SGT 900000001. Has anyone encountered this error...
