PSP firmware 5.01 released
Sony were quick to release a bug fix firmware update for the PSP. Firmware 5.01 fixes the previously posted issue where downloads from the PSP store would state you didn’t have sufficient memory space if you had a 8gb or 16gb memory stick inserted.
This download is available via the network update from your PSP XMB. (We will also have a link to the firmware once Sony update it to there website)

there are no 5.01 custom firmware out yet. you must downgrade it to latest custom firmware like 4.01 m33-2 to play iso game . i just go to the store i bought the psp and ask them to downgrade it. poof.. now i can play iso game..
can i downgrade psp in any store?
how can i downgrade my psp if i have a 5.01 firmware?
i dont wanna fuck my batterey and so on .
is there any other ways do downgrade my psp?
ok a few questions for crashhh, is this guide for downgrading ofw 5.01 also? and i would need to hard mod it either way to play iso cso or even install cfw? correct me remove or add if i am wrong….options: 1.wait for new cfw, 2. hard mod and install latest cfw, 3. have someone downgrade for me.
Kaspar, if there was another [easier] way, do you think people will still do this MMS Pandora battery way?
Ps3r, yes it’s for any official firmware. I accidentally upgraded mine to 5.01, now I have a CFW since I followed the steps.
is theis pandora work?
and is it safe?
if it is than i have to to that.
i really need to downgrade my psp.
can somebody give me a simply steps how can i do this?
So they want less money, and since we can’t buy the game, then we go to pspiso.com and download the game instead to get it for free ^_^. real smart sony….
Uhh, no you dont need to wait for new cfw (DOWNGRADE) you go down to any cfw you want. Also you can hard mod, Or soft od if your friends have hacked or 1.50 PSP
the only other way is to buy a datel pandora battery @ $10.15 with free shipping around the world anywhere (Very Good BUY). Then you can do it.
i have the same scenario with you guys pls help me to downgrade it again or there is still a patch to use so that the iso/cso will work in 5.00 pls help
hey could anyone tell me how to run iso and cso files in psp with 5.01 firmware
Were you even reading previous posts on this thread?
You can’t run ISO/CSO games on an official firmware. 5.01 is one, and there’s no CFW for it yet. Either way you have to downgrade your psp firmware and don’t start asking HOW, I’ve already answered it several times on this thread. If you won’t then buy games in UMDs.
So there’s no other way but we must have a pandora’s battery,
so when will cfw for 5.01 released ?
crash, whats the guide that you follow? i want to know, my version is 5.01 , i want to downgrade it
can you give me your email crash, i need helpp
Follow this guide

i did follow everything, but when i put my datel battery tool in it, all i see is a green light and blank screen
i followed the instruction carefully, i did everything until till when i put my datel battery in the psp, it only lights up with green light, but black screen
And you followed this:
\/ Please Read The Following Instructions Carefully \/
1. Take out any battery and insert your magic memory stick in your psp
2. Connect your ac adaptor and insert your Pandora battery WHILE holding L (or whatever you assigned)
- If it doesn’t start automatically, just turn on the psp with the switch like normal.
