2.0-2.80 Firmware PSP's Say -'' Hello World'' as New Exploit is Found !!

Today hundreds of PSP's will say hello to the world as they run their first piece of homebrew - the "Hello World" application. This will be made possible by a new exploit found that does not require one to own a copy of Grand Theft Auto: Liberty City Stories, but rather load a simple image off of your memory stick. This remarkable demonstration can be executed on 2.0, 2.01, 2.50, 2.60, 2.70, 2.71, and 2.80 firmwares!



If you are stumbling while reading this sentence, I wouldn’t be surprised. I just told you that you are now able to execute a homebrew application on 2.0-2.80 firmware. Now that you know it is possible, you are probably wondering how. With the combined effort of several dedicated users – NOPx86 (provided the original x86 proof of concept), psp250, skylark, joek2100, jimp, cswindle and Fanjita, they have managed to execute the first piece of homebrew on all firmwares above (and including) 2.0!



Less than a week ago, Fanjita dropped by our forums to tell us that a newly discovered exploit is indeed genuine and a usable exploit. This “exploit” started off as a discovery by NOPx86 in libtiff. He managed to find vulnerability and as a result – alter it to crash the PSP and many other image viewers. Fanjita, NOPx86 and the rest of this exploit team have put their hearts and souls into this exploit, and as a result they were able to execute a Hello World application on all PSP’s with the ability to view tiff files (2.0+). This application runs in "User Mode", but kernel mode will be achievable on all firmwares except 2.80.

Nice find!!! Wont be long now until a downgrader comes out.

 

That's great..soon fw 2.0 to 2.8 users can run homebrew just like 1.50.

 

Three Different opinions

1) "For anyone and everyone wondering what this does: nothing is installed, nothing is downgraded, the onlything that happened is it displayed some moving text on the screen. this is a hello world app demonstrating the psp's vulnerability to run unsigned code (not sony's, 3rd party) through a specially crafted tif file. That is all it does and all it will ever do. Now we have to wait for someone to make another tif file through this same vulnerability to run homebrew."

2) "This is great, though I think it should have stayed quiet for a bit. If Sony has missed this for this long, then there is always the chance that they would miss it in the next version which is supposed to have a PS1 emulator. Now Sony will definatly notice it and fix the exploit. This could have waited for a couple months in my opinion."

3) "The only people who deserve this exploit are those who cannot afford/cannot get an unpatched GTA:LCS umd and those with the TA-082. Anybody who upgraded beyond 2.6 doesn't deserve this."

Yeah i'm gonna give it a go on my bro's factory 2.6...just wanted to know whether its usable with TA-082 mobo??

 

Harsh words. But another exploit found. Im begging to think that Sony really F***** up on this console.

 

sony are getting more screwed the longer the consoles out, no wonder they want to release a newer version

 

I have tested this on my TA-082 2.6 PSP and it works but this obviously doesnt mean it will be the same way for a downgrader. Also the last time we used a TIFF exploit the downgrader came out the same day

 

cool think i think they shud try running homebrew on other fw than finding a downgrader it not necessary that the homebrew psp game shud b in iso format they cud find another format to load it on other fw

 

so is it going to work?
is there any currect games we could run using hello world

 

dunno check other sites

 

Grr, why couldnt they have waited? Now sony are going to patch it for when the ps1 emulator comes out in 3.0... If it wasnt noticed then maybe it would have been left in for 3.0...

 

what i dont understand is that, the downgrader and showing .tiff images what do they have in common? anyway hoping this
will solve problems

 

this is very similiar to the exploit for 2.0. Its causes a buffer overflow giving the ram more than it can handle.(which on 2.0 allowed a 1.5 update to run and install on your 2.0 PSP)

 

This is verry verry cool cant wait to see what happens with this !!!!! and ibjaredu nice skullmonkey dude that game is great ha bringg on psone emu

 

@josh
Hello world is not the exploit. Hello world was the first homebrew that the exploit ran.

@ibjaredu
The buffer overflow with the tiff exploit on 2.0 didnt allow us to run the 1.5 update. It allowed us to flash the 2.0 with a new version of 1.0 which then allowed us to run the update. It's basically a version changer.

 

we all no the people who updated to fw 2.80 are really lucky but i think it will be a while for fw 2.80 downgrader

 

man i cant wait for the down grade after my gf updated my psp to 2.71 iv been waiting for the downgrader so does any 1 av a idea when it will be out??

 

anyway, i told you there would be something out in septembre!

 

if u cant wait that long then trade your psp for fw 2.80 or buy a fw 2.60 psp NOTEsp is now set to 2.60 preset wen bought new
