Hello I read your post I guess am the only one here in the forum that solves psp issues oh well no problem I iwll put you through the process but what firmware do you want to downgrade too?

thanks for your help, actually i would like to downgrade it to custom firware 3.52 then step it up later. so can you show me how i would be gratefull. thanks

Ok, no wahala lets meet here tomorrow and we will start our little tutorial of mine ok later

Yea here is a simple tutorial how to go about downgrading from officail firmware to custom firmware but I must warn you do ask your own risk. Follow the instructions on the weblink I ve posted below and finally this method is for both downgrading and unbricking yea also creating pandora and memory magic stick is going to be a bit confusing make sure u read first b4 doing anything at all. If you ve any problem or question to ask feel free ok.

Note: You will need a psp using a customfirware to make a pandora battery.

all softwares and procedures you need is all in the link goodluck

yea i have seen what the site has to say, but my psp cannot go to the recovery mode since it is no longer running on a custom firmware so both cannot take place, but is there any way i can upgrade an official firware 3.71 to a custom firmware 3.80m33-3 because a friend of mine is currently runnin on an ofw 3.71 that will make it possible for me to use his own that will be upgraded to cfw to make both a pandora and a mms so mine can be downgraded. thanks

You need a psp running on a custom firware to create pandora battery and magic memorytic before u can downgrade to any firmware
