Downgrader For PSP Firmware 3.50 Released

by Mike Bendel on June 26, 2007 @ 3:27 pm

There’s a saying – good things come to those who wait. And it’s true, our friends over at Noobz have released what countless PSP owners have been anxiously waiting for – a firmware 3.50 downgrader! Coupled with the downgrader files below and a Lumines UMD disc, any PSP unit available on the market can now be downgraded to firmware 1.5.

Once on 1.5, you can run many of the freely available homebrew applications. Or even upgrade to Dark_AleX’s 3.40 OE-A – a souped up version of Sony’s 3.40 firmware – featuring support for homebrew, various plugins that enhance your PSP experience, and original PSone games (not limited to just the PS Store titles).

In a nutshell: Homebrew is now accessible to all PSP owners! As always, refer to the readme for detailed instructions on how to downgrade.

Please note Noobz cannot be responsible if you brick, and be forewarned if you use this downgrader on a previously downgraded TA-082/86 PSP, you will lock yourself out from running any official Sony updates (don’t worry, OE still works). However, Noobz plans to release a tool that will allow you to return to an official firmware in the future.

very nice....i'm sure a few of my mates would be delighted to hear this :D

TimTiger says:

WOO HOO!!!!!

MenaceInc says:

i'm tempted to upgrade my PSP to official 3.5 just to downgrade it... XD

shadowthor says:

You shouldn't upgrade and downgrade, it might brick your psp. At least you can help out your mates.

Tenshigami says:

Just out of curiousity, this "locked out" if you try to upgrade to official firmware after downgrading (assuming 1.5 and not OE)... what does it do when you run the update? brick the PSP or just refuse to upgrade your firmware? I'm aware of the OE firmware "DADADADADADA" Error, but what does the 3.30+ firmware updates do if it detects that you've messed with your PSP?

The flood gates are open, bring on the water...:biggrin:

x3sphere says:

I talked to Mathieulh about it.

So you'll just get the standard error message basically.

shadowthor says:

While some psps say hello to homebrew other will say goodbye.

Acerthief says:

i don't get this, kinda. it means i can't do this:

3.XX OE -> 1.5 -> 3.5(Locked)

or does it mean something else.

KAV32 says:

Yes! This Rules! I need to buy me a copy of Lumines so I can downgrade my brother's PSP and also my friends PSP for a price! heh j/k I will probably help them for free! :)

Roe says:

Yes now I can downgrade my 4 friends psp's....

RJC4LIFE says:

This is great news but I'm getting another PSP just for running games that require 350 to play. My 340 OeA PSP is good enough for everything else. Besides, as of yet, I can't play my demo of Fireteam Bravo (Socom) on 340 OEA..

Roe says:

Yo man 3.50oe is coming out soon. Dont waste your money on another psp

x3sphere says:

say you were previously on OE, then went to firmware 3.30 - 3.50 official. if you downgrade, you won't be able to run official updates. meh doesn't really matter though, like I said Noobz is working on a tool to fix it.

Chilly Willy says:

3.30+ examines the keys before upgrading. If they aren't valid, it refuses to upgrade (it doesn't brick, it simply won't update). The way to update is to fix the keys first. Someone (with my help) has already documented how to do this (over on MC). It's basically this:

Update to 2.71 official.

Fix the keys.

Update to 3.30+.

It's that simple. Sort of. After you update to 2.71 official, you have to use the 2.71 HEN to run homebrew to fix the keys. If you've done the corruption-free downgrade, this means just fixing key 5. Otherwise, you use KeyCleaner to fix all the keys but 5, THEN fix key 5. If you've used MY method of setting key 5, you can use 1.5 Enabler to revert it. KeyCleaner will change other methods of patching key 5 into mine, so that's not much of an issue.

TimTiger says:

It's damn hard to find a copy of lumines now. Maybe if I check in a couple of weeks I may find one.

shadowthor says:

It will be even harder to find it then it is right now if you wait for a few weeks.

Roe says:

Just look around the stores and they have loads.

TimTiger says:

The problem is that around here the stores dont carry them anymore since they are an "old game" maybe I can find one at walmart or somethin.

Roe says:

yeah or look in the preowned section of game stores thats were i got mine

TimTiger says:

I tried that and all the preowned places sold out of that game in the first 20 min after the store opened. The word got around way too fast. :glare:

Roe says:

I guess im just lucky I live in Ireland where hardly anybody nows anything about this stuff

TimTiger says:

Well it happens, I'm sure there will be a flood of returns once people downgrade and want to return the game. But thanks for the help anyway 8)

RJC4LIFE says:

I got mine at Gamestop yesterday for 12.99 US.

Roe says:

Well i'll see if i can sell you mine as soon as i finish downgrading my friends psps

RJC4LIFE says:

Ok then, 350 OEA is worth waiting for I guess, so thanks for saving my $170 on another PSP.

dennis96411 says:

Yeah man!!Don't waste your money on another psp!!Besides,it's just a stupid demo.

Any way,the 3.50 OE was canceled and the 3.51 OE was on it's way,it supports your demo.

So just wait...

TimTiger says:

Thanks, but the shipping costs would be too much for the both of us since It looks like over seas shipping. but thank you anyway.:biggrin:

RJC4LIFE says:

Well guess I will be buying a new psp if I want to play God Of War..now that OE is no more..

TimTiger says:

You dont need to do that, you can always install devhooks when they come out and also there will be others who will pickup after DAX. :)
