2.80 Kernel Mode Exploit Found!

greg | December 21, 2006

Team C+D have shared a wonderful gift for 2.80 owners this holiday season. It’s a few bytes big and wrapped in a proof-of-concept package — *gives it a shake* — you guessed it, a kernel mode exploit! Its been confirmed by many reputable sources and seems to have true potential.

Nothing has developed from it yet; meaning no downgrader or functioning kernel mode apps. But, be patient! Rest assure the true hackers are working their voodoo magic.

The download below is proof-of-concept; only source code. End-users, sit tight — expect to see some progress in the near future. It’s only a matter of time.

Fantastic work Team C+D!

Yes! I got my brother a PSP and downgraded his to 1.5 and was having so much fun with it I was really considering selling my 2.8 for what I could get for it and getting a second hand 2.71 or lower PSP. Now, I don’t have to! Keep up the great work guys!

Comment by Shaddowknight
2006-12-21 07:50:21

you do not use this, this is a proof-of-concept
this does nothing for people who currently want to downgrade, this is a tool that shows developers how to access the kernal mode exploit

Comment by Shaddowknight
2006-12-21 07:57:56

let everyone be reminded this program does not downgrade, its just a proof-of-concept which MAY allow you to downgrade once someone uses the exploit (which this program shows how to access) to make one

TA-082 users can never downgrade below 2.5 or 2.6 without major problems and likely bricking (one of them… i cant remember) (this is due to a differnt motherboard configuration)

2006-12-21 09:50:24

I’m sorry, I’m VERY new to PSP and this whole hack/homebrew/downgrade discussion..

Does this only mean that you can downgrade your PSP firmware from 2.8 to 1.5, or does it mean that you can use homebrew on your PSP with 2.8 firmware?

Comment by Shaddowknight
2006-12-21 10:17:09

this could lead to both

Comment by Erik

Comment by Erik
2007-01-07 11:40:03

My mistake.. and a BIG one it was.
My firmware version is 2.81 and not 2.71.. No one is more disappointed than me.
I take it the kernel exploit was exclusive to 2.80 and not for any later versions. Am I correct. Please tell me I’m wrong.

(Comments wont nest below this level)

Comment by yourgrandma
2006-12-21 10:08:34

…no unless your useing iso’s or playing emulated games that you don’t own

 
Comment by Shaddowknight
2006-12-21 10:21:56

isos are legal if you back up your own game
roms are legal if you own the original game or delete it within 24 hours of download
emulators are legal- however some require a BIOS file that is illegal to distribute over the internet (yet its still done)

the thing is you likely wont get in major trouble for downloading a game or two- just downloading many or distributing them to others is what gets people in trouble

You’re a fool if you update to 3.03 right before a downgrader for 2.80 is released. Sit tight, you impatient little monkey.

 
 
Comment by KMFDM_Kid2000
2006-12-21 17:12:22

Bunch of TARDS I SWEAR, this isn’t a DOWNGRADER, it’s KERNEL mode, do a bit of reasearch will ya? Just means it’s an exploit that allows this version of firmware to be manipulated in ways it COULDN’T before which MAY lead to homebrew, and/or a downgrader. It doesn’t mean you can now go 2.80 –> 1.50.

I swear the general public was brought up on a steady diet of crunchy paint chips -.-

“Just means it’s an exploit that allows this version of firmware to be manipulated in ways it COULDN’T before which MAY lead to homebrew, and/or a downgrader.”

Actually, there is already homebrew lol.
well, I agree with the paint chip comment :P

Comment by The Matster
2006-12-21 17:52:06

it looks like there very well might be a downgrader I can’t be positive but it looks promising. So I say this once you get your 1.5 back or 2.71 custom don’t upgrade your psp’s unless you don’t care about iso’s and homebrew and some bitching emulators like neo geo and capcom sytems. Having said that even if you have 2.82 or 3.0 I say still don’t update unless u have to they’re even talking about a possible exploit for 3.0 firmware

could you play homebrew on it

Comment by nicko01
2006-12-21 20:57:12

yes you can play homebrew on 2.80.
not 2.81, 2.82, 3.00, 3.01, 3.02, or 3.03
Kernel mode apps are much better than user mode apps. like being able to use the ir port on the psp, and downgrading.

Thanks,Alex

Comment by Shaddowknight
2006-12-22 08:55:31

its not that simple
the programs like that need to be built around the exploit
they arent right now- and they need to be redone and rigorously tested for them to be re-released

its useless downloading this. you should wait tell a downgrader comes out and u have to extract the rar file using winrar [downloaded it from google ]

if you downloaded this and arent a programmer, delete it
this is for programmers to learn to make use of the kernal exploit, it is not for the normal homebrew user

(Comments wont nest below this level)

I THINK IS VERY GOOD , BECAUSE THE HOMEBREW IS AMAZING BUT WE MUST KEEP BUYING THE GOOD GAMES (LIKE METAL GEAR) ON ORIGINAL JUST THINK ABOUT IT IF WE DONT BUY FOR AT LEAST 1 GAME EVERY 4 MONTHS THE PSP IS GOING TO BE FUC.KED … ANYWAY GREAT WORK AND KEEP IT UP (BUY A WII AND THE POWERFUL PS3 THE XBOX IS A SH.IT!!!!)
