PSP Firmware 5.51 Released

greg | June 11, 2009

Sony acting suspicious with a [minor] firmware bump… PSP Firmware 5.51 just hit Network Update; you can also grab it below.

So what’s new? Apparently the same ol’ nonsense — improved system software stability during the use of some features. That’s it.

I wouldn’t recommend updating if you’re the hacked but Pandoraless, PSP-3000, or TA-088v3 type.

As sony, with there little updates here and there… attempting (but failing) with all their might to squash homebrew on the PSP.

The new patch does the PSN thing and allows for account set up, haven’t noticed anything else yet thats new but will keep posted.

I just wish the new hack would come soon, got like 10 games i wanna backup and play with my bro without having doubles of everything.

So you’re saying that most of the system updates for psp have something to keep users from hacking?

PSP Go is what they’re up to. I’m interested to see if it is unhackable. Or what they have done to prevent hacks. Obviously someone will find something to make it say ‘Hello World’

Maybe Sony discovered an exploit in 5.50 which no-one in the homebrew community did……..

Comment by Xavis
2009-06-11 17:29:21

ya probobly, there thinking like the hackers to beat them, aculy thats kinda smart, but still need one baddass feature to make it worth hacking hence why DAX said he wasent making the 5.50 into a cfw

Thats a nice way to think. Although there was that LIBTIFF thing that they may have patched.

I think their trying some PSN store features to see how well it would be on the Go so then they can make ajustments and such to find the best running stuff on the PSP go

SCEA have small patches to stop cfw, but it can be patch again by dax if he wanted to.

I don’t get why anyone needs to update firmware until their is a hole version ahead even then not much point is anyone making custom firmware anymore?

Comment by Suijen
2009-06-13 10:24:08

Lol, I thought that was funny as hell. But no I rarely, even look at the PSN. If I had the money to afford their overly priced stuff there then I probably wouldn’t be here looking for free / homebrewed materials right.

2009-06-13 16:04:27

ether some kid trying to be like the idiot company or is sony trying to tell us to update and hope we do just because they tell us to,

when you guys get an update out, im sure lots of people say “kiss my ass”
the only time we update is when a new m33 comes out

Dax,you gotta release the 5.51 m33 cause my psp ofw is 5.50 and I can’t update it to 5.50 gen-a and i need cfw for my psp 5.50.

 
Comment by MPT
2009-06-22 13:46:14

1. To dude: even if DAX made another M33, you still need a pandora battery.
2. DAX probably wont make an M33 for his firmware coz its not significant enough.
3. Edison Carter needs to update LCS cheatdevice coz it doesnt work on higher M33 versions such as 5.00 M33 or higher.
4.By 2011 sony will have probably stopped prducing UMDs because the PSP Go doesn’t need them, which means, unless the digital downloads get hacked, which is very unlikely, an end to free ISOs/CSOs for us.
Could this be the end of the PSP-Homebrew Scene?

hey i was wondering if the is any hacks for a psp running on firmware 5.51 such as games or like any hacks for firmware 5.51

 
Comment by Riki
2009-06-23 18:45:13

Same question as a lot of people have, I hacked the Wii so decided to try the PSP as Im sick of the slow release of any decent PSN PSOne Games. With the hacks I can put CC or FF games on the PSP.

But I updated to 5.51 so now when i try the custom firmware it says “corrupt data” blah blah..is there anything I can do?

Please advise

Oh and its an original UK PSP 1000 never modded or customed in anyway

i dont understand most of you people all know that sony pushes out these updates to stop the hackers out there from hacking there device. U should all know NEVER TO UPDATE your PSP device. this was rule #1 since firmware 1.51 came out that only patched the TIFF problem that hackers found in the system.
so lets see less then 1 week after the psp was rls a tiff was rls to hack it. what did sony do patched it and rls 1.51 on there server so all the dumb tarts in the world would go HEY THERE IS A NEW UPDATE it must have some cool stuff in it. ( BUT DOES NOT HAVE ANYTHING BUT A PATCH OF THE TIFF )
So how many people out there downloaded the 1.51 because they had no cule and just thought it was a new update of new feats. MANY is the word. the only people that dont update anything are people waiting for hacks and stuff like that.

seems that with this new update sony is trying there best to stop the newer units from not doing this anymore. but guess what sonys team of people are just not as smart as the hackers in the scene.

its just a big cat and mouse game and we are winning the game so the cat is just mad and needs to get that little mouse because its staving right now

if it still has warranty you may have a chance to purposley brick it
Sony will get you a new one and you can update to 5.00m33 and alls well

Dammit! I updated my PSP 3000 to 5.51, then found out about stuff like the HEN. Anyway, does anyone agree with me on this? Here goes: Sony should make an OFW that downgrades the PSP itself. I mean look at all the stuff the iPhone can do! Do the above so WE can put homebrew apps on the PSP. We worked for our money. I’m gonna spend it on an iPhone. F |_| € ]< the PSP go. You say you can’t hack it anyway. Sony, one lost sale unless you do the above. And you need my money because you guys are losing money…

xD the iphone isnt made to play games like the psp.
The PSP isnt made just for selling consoles but games too. So SONY would not benefit from the feature described above.
i have been searching for months to find an exploit for the 5.00FW and i found it last month.My PSP’s version was 3.71. Because i foresaw the hacks coming, i did not update it. Now its time for all of you to wait…

Hi all !

Me too, upgraded my PSP to 5.51… Been reading all I could find about hacking it on the web. So I got my hopes back up when I read about about ChickHEN R3, but now it seems that R3 release won’t be made to hack 5.51 firmware, but 5.50 firmware, so what am I supposed to do ?

Is there no way to hack my psp ? No way to downgrade it ?

If anyone has valuable information about hacking the psp once it’s running FW 5.51, please share.

Idea: Don’t update until PSP Go! comes out. Then more hackers will arise. If the Go! runs the same OFW as a 3000, there will be more hackers that will arise, allowing more progress in hacking to be made on the 3000, as well as the Go!

ChickenHEN R4 for a future version of OFW? (Whenever the fuck that’ll be…)

Hello, Gentlemen.
As many of you, I was one of those people who had no idea about the hacking world when I first purchased my PSP 3000. Like a kid with a brand new toy, I wanted everything to be updated and to the best performance….So I also updated the PSP 3000 to 5.51 and later came to notice that it could hacked. I love the PSP and would love so very much to customize it to it’s full potential. As many of you I would like a Customized Firmware for 5.51 or a way to downgrade it without being “bricked.” I know sooner or later that dream will come true, but I think we all need to wait patiently for the hack team to do their magic. Hopefully someone is out there right now putting their PSP at risk for our sakes.

Been a console gamer 4 ever and finally got a psp. Needless to say I fell in love. BUT, I had no idea what this thing could do with homebrew.

Too bad I didnt figure it out before i updated to 5.51

Im a music producer, and I’d love to start making homebrew music production roms and apps, but I dont know how to downgrade. Any ideas?

I feel sorry for you guys who upgraded to the new FW…NOT! What did yall expect? “Oh ima upgrade and see what the new OFW has and Dark alex and the hack team is gonna come out with a patch to save me!” Idiots! Why not just spend the time waiting for an m33 version by just havin fun with your ISO’s and homebrew apps? Ha im laughing at u all xD

Comment by EndlessMike
2009-07-26 19:44:32

Well excuse some of us for being new to the homebrew scene -_-”"

A friend of mine hacked my psp for me a month ago and forgot to tell me to update. Found out the hard way that that is the worse thing a hacked psp should do. Now I’m just like all the others who are holding their breath for 5.51m33…
Ah well. In the meantime it’s given me an excuse to show my wii more love instead of collecting dust. For all I know, Punch Out might keep me busy until the the day the cfw finally arrives! At least here’s hoping…

quite a few people with custom firmware have updated, and are now stuck. That seems like a win to be honest…
