Hey Dave. I just upgraded from 1.5 to firmware version 2.0 on my Sony PSP device and now all the games I grabbed off the net don’t work any more. That stinks. Is there a way I can roll back my unit to the 1.5 Sony PSP firmware?
First the bad news: no, as far as I am aware, there’s no legitimate method of backing up a firmware version, whether you’re going back from 2.0 to 1.5 or 2.5 to 1.5, or whatever. I’m sure that’s deliberate on Sony’s part with the PSP, but in general, no you can’t do that.
Now the really bad news: there are some sites that are claiming that they have firmware 1.5 downgrades you can run on your Sony PSP and have it magically go back from firmware 2.x to firmware 1.5.
Be Highly Suspicious of Sony PSP Firmware Downgraders!
They might well be cleverly disguised trojan horses, programs that are actually written to destroy your PSP unit. If you run one of these downgrade applications, it can actually remove some key files from your PSP and render it inoperable, which would definitely ruin your day.
As far as I have read, there’s also no way to send your PSP to Sony or otherwise have someone clone their OS onto your system as a recovery mechanism (though theoretically you should be able to accomplish this task with some simple programming). If you run this trojan, known in antivirus circles as Trojan.PSPBrick, you’ll have a dead, throw it away, nothing you can do to fix it Sony PSP unit.
Quoting from a ZDnet article on this subject: “Basically the (PSP) is completely inoperable, and you’ve lost your device,” said Eric Chien, the principal software engineer at Symantec Security Response. “It’s called ‘bricking.'”
If you’ve upgraded to the 2.x firmware release, I am afraid that you’re stuck with it. Just don’t get stung by this trojan while trying to fix your unit.
Update: To be fair, I have heard from a number of PSP owners that they have successfully downgraded their PSP firmware, from 2.6 back to 1.5, 2.5 back to 1.5, and so on. I imagine you could flip a coin and hope that a given PSP firmware site has a legit and trustworthy downgrader that you can run on your Sony PSP with good results, but to me this is still a pretty risky move because while the odds of success might be pretty good, the cost of failure is pretty darn high too.
As with anything to do with computing, you need to decide for yourself. If you can find a credible, trustworthy site and believe the postings from other folk that they’ve had success with the downgrade, go ahead and try it. Whether you succeed or fail, please do pop back here and let us know too, but, again, how will we know your posting is legit, not a trick intended to get others to download a “brick” application?
Round and round. You can see the basic dilemma here.
Good luck, whatever you choose to do.

You can downgrade a PSP, as a matter of fact you can hack a PSP like a computer using different RAR programs built for PSP’s, go to pspslimhacks.com for more info.
i have a psp but i need to know how to downgrade it.someone e-mail isaacartist07@yahoo.com..
Mine is very bad compared to all these complains i have read. Mine is a version 5.02 and i need to downgrade it urgently
I downloaded the driver detective, but when installing my security program quarantined several files following a virus check.
What now?
Theres a new way to downgrade ALL firmwares to 1.50 and unbrick ALL psp’s!!!
We call it the Pandora’s Battery. But after downgrading, you wont be able to use the battery you used to downgrade.If your PSP is bricked you will need another PSP to run the applications. It’s basic steps are:
1- Turn a PSP battery to a jigkick battery.
2- Add some files at the memory card and run an homebrew application at the PSP.
3- Insert the memory card and the battery to the bricked (or the psp you want to downgrade)PSP and open it. You will see a menu. Press x and follow the stuff shown. Advanced info can be found at:
http://www.noobz.eu/joomla/news/pandoras-battery.html
when I put the memory stick in my psp it says that is no memory stick and when I format it say the same ting
Ok, so I just thought I’d throw my 2 cents in here.
So, as someone has stated before, there is the Pandora Battery. This could be the greatest piece of reverse engineering in the PSP’s homebrew history.
Now, if you want to roll back firmware, that’s a difficult one. You can only downgrade a 2.0 and 2.71 without the use of a Pandora Battery or an unpatched game.
If you want to downgrade other versions, you will have to use either an unpatched copy of Grand Theft Auto: Liberty City Stories or an unpatched copy of Lumines, depending on what firmware you have.
Your best bet is to use the Pandora Battery.
Then, google Dark Alex and upgrade to 3.90 M33 firmware.
Also, download iR Shell after you get the M33 firmware. It’s extremely helpful.

I JUST BOUGHT A PSP WITH A 3.90 FIRMWARE.
I NEED TO KNOW IF I COULD EVER DOWNGRADE IT TO A LOWER FIRMWARE.
I NEED HELP!!!!!!!!!!
i downgraded my psp from 3.71 m33-2 to 1.5 using a guied found on youtube. worked like a charm, no problems
There is actually an unbricker for the PSP. It also downgrades the PSP to firmware 1.5, more info here http://www.noobz.eu/joomla/news/unbricker-for-all-firmwares.html
Umm you may now downgrade your psp from ANY and all firmware versions to 3.71m33 which is a custom firmware that allows you to play all your 1.5apps. but in order to do this you need help from a friend that has a psp under 3.52 i think and you have to kill a psp battery but after that you will be fine. I dont have time right now to explain it myself so you will just need to go to google and type in “pandora’s battery” also this will unbrick all your psp’s as well.
He can anyone tell me how to see what is my firmware version???
