Help remove cfw from psp 2001

Ive just bought a PSP 2001 from eBay. Everything seems to work until i wanted to log into my PSN account and then it asks to connect to the internet which i tried to do but my wifi isnt supported (i have verizon fios). so i tried to do an update through the computer and the current update is 6.61. when i tried to install the update i get "The system software of your PSP system is 9.90. there is no need to update". i dont know anything about cfw and i think thats what i have on there. the cfw is "5.50 Prome-4" is there any way i can remove it?

You need a first run original Sony PSP battery or a "Pandora Battery".

There was a tool to change the identifier of the original first run battery to a "Pandora" battery, which allowed flashing of CFWs.

If not, you can probably still find one on Ebay.

This article explained how CFW was flashed on the PSP to understand what is going on.

You may be able to do it in reverse.
