Its just been posted in the forums about a new exploit uncovered by Yoshihiro and the wab team, heres some of it:

How To :

!!! HOW use it !!!
Put your two folders on your games folders and run it .your game boot
and freeze your psps on white screen .after your psps shutdown it's
because your second eboot.pbp like on kxploit "From pspsdev team for psp 1.5"
is corrupted juste find teh 02000800 and replace the 08 by 01 for test in
the header of your elf it's easy but it's proof concept the psp 2.0 can read
the elf but in another format .

This post would have made more sense if a Jawa wrote it.

OK Run homebrew games on 2.0! It's easy but... It's proof of concept.

Well it's thanks for your efforts but... easier for white screen maken, explanation.

So does this mean if youse update your bios and convert your exploited folder it runs?
Anyone tried it yet? Any Videos? Sorry for being so skeptical but I'm itchin to use 2.0 but I am not willing to trade my PSP1.5 for proof of concept and a white screen.

Title: JAP 2.0 Firmware Contains Overflow?
From: "http://www.psp-spot.com"

As we all know we were the first to report about the V2.0 firmware being released in North America, but there was still a couple of things I had on my mind. Even though we did recieve the 2.0 North American firmware tonight, the question why was it delayed is still on my head. Personally, I think the original V2.0 firmware was exploitable, and that patched it up in the North American release. Also interesting enough, the download link now to the JAP 2.0 firmware has changed. Check out the MD5 On Them

MD5 For USV200_EBOOT.PBP = 50c7032754835b588319c1a6c652cdc0
MD5 For JAPV200_EBOOT.PBP = 62f6d3d18038f463092e3d6653fae195

The original link to the JAP 2.0 Firmware was
http://dj01.psp.update.playstation.o...e195/EBOOT.PBP

And Now IS

http://dj01.psp.update.playstation.o...cdc0/EBOOT.PBP

as you can see they are trying to hide something here.

So calling all crackers and hackers and coders and wannabe's! Let's find what they are hiding in JAP2.0!

ok, for all you idiots that didnt click the link that said
"More info on this news here --> http://www.dcemu.co.uk/vbulletin/showthread.php?t=9716"

No, it dosnt run homebrew.. in fact, its not really anything at all as far as some of you are concerned. If anyone has tried to launch homebrew on a 2.0 they know that the file is INSTANTLY corrupted. It wont even try to begin to launch the file. By simply replacing a 1 with an 8 in a hex editor, you can actually allow it to try to launch.

THIS DOES NOT LAUNCH THE ACTUAL PROGRAM AT ALL. All this does is get it started. There is no reason to be skeptical. Its might not seem like an important progress, but it is a step in the direction of launching the file.

as for what they are hiding in the japanese firm update, i think that there is an exploit hidden in the japanese firmware as well. why else would they take so long releasing it to the states?

well if they are hiding somthing in the j2.0 then its something to look for. But you should crack the newer version first that way everyone can update and play homebrew. Then go back to see what its hideing. I think that the last minute they added some sercurity to it and went back and added it to j2.0.
