2.80 must have kernal!

**benh** · September 3rd, 2006, 13:01

Hi

I was thinking about downgrading and how we could exploit different features, then it hit me!

2.80 must have kernal otherwise how do sony write there firmware updates to the nand flash memory, so there must be some kind of kernal access to the nand flash memory.

Maybe dark_alex and his team could exploit the way sony writes to the nand flash and make it so that a downgrader could write to the nand flash the same way.

what are your thoughts?

every firmware has kernel...it's only a matter if coders can bypass the security checks in place to be able to have access in kernel mode. It'll only be a matter of time though, be patient

why has everyone been saying that there isnt kernel access on firmware 2.80? is it the fact that there isnt kernel access on 2.80 because it hasnt been cracked yet?

ok cause the 2.71 downgrader hasnt worked for me even though it should work so i was waiting untill a 2.80 downgrader came out then i was gonna try that

couldnt people like fanjita or dark alex and so on not like look at the firmware updates eboots and see if there is a code that manages to bypass the security. so they would have to look at the version 3.0 eboot to be able to crack the 2.80 security.

so in theory all firmwares from now on should be crackable but it will just be a lot harder each time and i mean a whole lot harder.

interesting theroy

all firmwares have kernel access, all the games released by sony run in kernel mode.

i think the security on the update EBOOT is broken when you extract the files.

sony dont write to the flash with an exploit, they have the security code to allow their applications to run from the memory stick.
