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.

omg! YES please say can get emulators and loaders on 2.7 ... i updated like a day before the 2.6 exploit was found... lol

I did the same as you (except a week before, you got pwned more than me ) and ended up buying a new psp and downgraded it, you may be able to get an exchange, I couldnt because I bought mine from the US and they wont exchange them in the UK.

Anyhow, no not just yet, although this opens the door for a potential downgrader or emulator, but more likely a downgrader, which is preferable so sit tight. Do not upgrade above what you are already. I say this incase Sony brings out any suprise updates in sight of this new exploit.

Soon you should be in the world of 1.50 or now even 1.00 which is already possible for people with 1.50.

But I will only going to 1.00 on my currently 2.71 PSP Since there is always a slight risk - AS WITH ANY DOWNGRADER, of bricking your system. (If a downgrader comes out that is.)

damn my RSOD'd PSP

Slight problem: you can't put the PSP into standby with this running.
In fact, you can't actually turn the damn thing off!

2.80 firmware.

* RaceProUK goes to remove battery

That wasn't my initial reaction. It started off with 'Fuck, I crashed it!', followed shortly by 'Holy shit! This actually works!'

* RaceProUK might start looking for homebrew now

I got a weird flickering with it though.

I removed the battery while updating and still not working

While updating what, this is just a proofe of concept, its not a downgrader, and doesn't mean that you can start running homebrew, just means that doors have been opened and MAYBE soon you will be able to play homebrew on newer firmware, or downgrade. But at the minute this is NOT possible guys.

of course its possible, they just haven't coded any loader for it yet.

So what happens next? This shows that we can run code via this exploit. It won't be too hard to develop an eLoader that can use this exploit on v2.0 - v2.6. v2.7+ will be harder, due to extra security, but will happen a little later. Kernel mode is unavailable on v2.8, but it is likely that a downgrader is possible on all other firmwares. But then, with the possibility of kernel homebrew running without the need for a game UMD, why would you need to downgrade?

Full credit is given in the Hello World, but repeated here: Thanks to NOPx86 for the initial proof of concept on the x86 processor, and psp250, Skylark, Joek2100, CSwindle, JimP and Fanjita for the PSP work. Thanks also to Ditlew, HarleyG and our families for general support during this work.
