Hi ive been trying to install the latest cfw 6.38 on my PSP 1000.
I am currently running system software 5.50 Prome-4.

When I do try to install the latest custom firmware i get the error message;
"The system software of your PSP system is version 9.90.
There is no need to update." i dont seem to understand what is going wrong.

ps with the download link for the custom firm
ware it said; "From 5.50Prometheus -> OK(may need to edit version.txt)" what does it mean edit version?

Thanks in advance
