Hii! I’m trying to get an old PSP 1003 (PSP 1000) working again and update it to a newer firmware, but I’ve run into a problem. The system is currently on 5.50 prome-4, so it looks like it already has custom firmware installed (likely from years ago) to me it seems like the current CFW is spoofing the firmware version (says it on 9.90 and up to date) or blocking updates, but I’m not sure how to safely remove/replace it.

what i’ve tried to do:

• tried web archive for official 6.61

• tried the pspunk version of the update

• tried formatting flash1 in recovery menu

• tried resetting settings

• tried to skip straight to downloading ARK

I’m not knowledgeable on PSPs at all, any help is appreciated !!
