PSP Firmware 5.50 Savegame Vulnerability Found; Exploit Released


Perhaps this is the reason behind Sony issuing PSP Firmware Update 5.51... A German developer who goes by the name of Miche2245 has discovered a Save Game vulnerability in PSP Firmware 5.50. Currently the Japanese version of Monster Hunter Freedom 2 and the English version of Need for Speed: Underground work.

The exploit you may download below is for Monster Hunter 2. Once executed by loading the save game you can then utilize ChickHEN -- the homebrew enabler -- under PSP Firmware 5.50.

Props Miche2245. Nice work.

sweet! i don't have 5.50 but this will be great for those who do and aren't able to use homebrew!ps:first!

Its fake. Man PSP-hack suck cos its fake. Proven on PSP-GEN. Shame greg..posting fake news getting users hopes up.

pspgen never said it was fake? they posted the news too...

Sweet another one bites the dust.. firmware that is.

WOW! This is amazing! I haven't tried it because I already have a hacked psp, but this is seriously awesome! But I might try it with my cousin's 3000.

Dude, i'm nos expert, but you should wait to other people use it, or your cousin's psp will BRICK!!

how do u activate the exploit

Can CFWenabler be used with this?

but we need to buy those games D:NO?

Yes, you would in fact have to buy either of the 2 games to use this exploit.I had to ebay around for a unpatched original copy of gta liberty city stories to be the only way of hacking my psp back in the day.

kk but later someone will do this exploit whitout using this games :Pi hopeand i have to ask that if we buy a psp 3000 right now it will come whit ofw 5.50 or the 5.51 that is sony updating?

yea i used the gta exploit also but i didnt have 2 ebay for it i bought the game w/o knowing about the exploit until my friend got me into it

Need for speed is an EA game right? would EA do a re-release of that game to patch the exploit like Rockstar did with Liberty City. I think the company that made Lumines did the same thing and released a patched version of the game.

No, I don't think so because this game is not producing any more........

mhmm, these odd chances of figuring out stuff like this always amazes me, i wonder if it'll work for 5.51 the exploit may still exist, since the original post about the updates seem purely speculative

man i wish i had these games but gamestop dont sell them

Man just one step closer for a full exploit!!Why did I have to download 5.50 on my 3000 to go through all this trouble? LOL

keep in mind ppl that there may be more saves that this exploit will work with XD

Let me tell you Sony, that is much too late, to fix the exploits.

[Followed by an drum, then silence]

nice job.

sooooo... 1. how do you use this2. i have the game and i made a totally LEGAL backup of it in iso form and was wondering if that would work

As MR.T once said, i pity the fool.You don't need this if you have the ability to backup your games. How would you use this on a OFW PSP? You can't run isos.Something tells me it isn't a legit back up.

haha word. I smell a cheat

What's that? PIRATES ON A HACKING SITE!?!?1?one?

More info is needed here.1) Where is the savedata for the NFS?2) Which psp it works on? PSP1000,PSP 2000, TA-088v3, PSP 3000 or all PSPs with FW5.50???3) only works with MH2 Jap or other vers?4) Wat's the UMD code for the MH2?Who can clear these question? Well maybe the German site did explained, but sorry I do not understand German.Thanks in advance.

You can translate with "google translate"

I think what they are saying is that it is regular ChickHen R2, but it now works on 5.50 ofw with this new savegame exploit. so just download chickhen r2 and read the readme inside of it.

and if you dont have mh2 JAP, then look for it on ebay lol

It has too many steps for launch homebrew or play a back-up if possible.Open PSPLaunch UMDUse Exploit SaveThen use HENThen apply or activate CFEI think someone'll make a new exploit without UMD.

omfg how do you people find this stuff, this is unbelievable

are u saying that this works for 3000? :O if it does.. im going to cry :D

will this work on psp3k with ofw 5.50?can anyone teach me h0w?

Wow...nah fake...

How do you find an exploit?

by being a genius :)

Or just plain lucky.

Augh this sucks. One of the switches for the UMD drive on my PSP 3000 broke, so I have to send it in to get it fixed. However, they're going to upgrade it to an unhackable firmware. I guess I'll just download copies of all the games I have and load via ISO forever now.

so does it work and does it work with other games i heard silent hill origins worked

I checked with hex editor. In MHP2 savegame folder hw.bin is same as h.bin file which is used for ChickHEN R2.Maybe it can be apply to another UMDs.But I dont know how.

Ah man, I can't wait till there's an exploit found for 5.51 OFW, I got a used blue 2000 with it. I'll probably be waiting awhile till it happens though

Umm, unless your 2000 has a TA-083v2 mobo you should be able to go the pandora route. Are you really that unlucky?

Yes, I am : (

Unlucky no, uninformed yes. Whoever updated that PSP had no friggin clue what he/she was doing and now pays the dredful price of patience. Patience is a virtue after all. ;)

Nice find, but they should have only released an exploit for the more popular game, and kept the other a secret. Then once that gets patched, release the next one. On the off chance Sony patches both, still release the second one so at least those who didn't update can use it.Take a lesson from the Wii guys. Find several exploits, release one at a time as existing ones get patched.

Sucks 4 me tho got a psp-3000 with 5.51 ofw :(

Hope this works with other UMDs. I got 4 UMDs (Fifa 07, Nba 07, Moh and Vice City) but none of them is suitable with this exploit

Yea...The chances of an Exploit falling into your lap for a game you already have are very slim, you should just buy the exploitable UMD, it'd be worth it.

From what I hear, this exploit is BS.

Yeah, actually I looked up more articles regarding this exploit and apparently it's just a crash, also all the articles about this "exploit" was from May
