Breaking News: Full Kernal Access for 2.5/2.6 users Via New exploit

[mr_nick666]

Well sure I could upgrade my 1.50 to 2.60. But its not like the mod chip. You would still need some way (eLoader) to load the homebrew. Unless custom firmwares can be created to upgrade to without a mod chip, it may not be as simple as it is with 1.50. (Just select your homebrew app, press X and your all set)...

Its just my own opinion but I'm skeptical that maybe not ALL 1.50 homebrew would work after upgrading.

And about the web browser and codecs. I have all of that with my 1.50. 2.50 can be fully emulated and actually the web browser works better now for 1.50 users because we can overclock the PSP which makes the PSP browser CRAZY fast. Much faster than it is on 2.00+ (I have compared) 1.50 PSP's can have all video codecs of 2.50 & 2.60 and THEN SOME. 2.60 PSP's are limited to AVC 320x240 resolution. But PMP on a 1.50 can play videos at full 480x272 resolution.

So in closing I really think 1.50 will remain the superior firmware as far as homebrew goes. And I would very much prefer being able to load higher firmwares or features of higher firmwares at will while maintaining 100% homebrew capable 1.50 firmware.

As a 1.5 user I say sage words my friend
Im interested to see how this pans out though...

and the worst part about it, its called ****in kernel with an E not kernal, that just pisses me off!

anyway, seems like a nice exploit, can't wait to use it

I still won't upgrade my 1.5 :-)
It's nice to see that people with higher firmware will be able to have kernel access ;-)

Ok my thoughts after reading this thread, (may be late)
those of you who said they would not want to load up gta everytime, iRShell can help, load up gta one time and rund your eboots, umd's and such from that. put psp to sleep and continue next time in iRshell. ]
2 Second no downgrader, don't remeber what it was called but they locked something in 2.5 that would make it "impossible" i will research the name of what the file is that locks it, if it is that serious to anyone.

so am i to assume that even though kernal mode is accessible (or at least in theory right now) the flash will still not be accessible through this?

Why wouldn't this let us access the flash?
As far as I know, if you have full kernel access then you will be able to access the flash.

Hopefully we can access flash, otherwise my previous idea for 1.0/1.5 users won't work:

With 0okm's Diehard Firmware 1.00 Backup & Restore program it should be posible to go from fw 1.00 to ANY firmware up to 2.60, and still be able to restore 1.00 again!
(It won't work with current program, but could if 0okm modifies it)

If you are on firmware 1.5, you might not want to upgrade just yet...
For people that haven't upgraded yet and are on fw 1.50, they should back up their flash first!
If for any reason you might want to return to 1.5, it should be possible!

If kernel mode can be accessed, and flash can be written/read then it should be possible to backup: 1.00, 1.50, 2.50 & 2.60.
If so, the following should also be possible:

1. Backup fw 1.00/1.50
2. Upgrade to whatever firmware you want (up to 2.60)
3. Upgrade to either 2.50 or 2.60
4. Run the restore program to go back to fw 1.00/1.50!

This will not work yet (especially if this exploit is fake of course), but it should be easy for 0okm to change his program to do that.
Or someone else should be able to create a program to do that.

As long as we can use the kernel functions in pspnand_driver.h this should be possible.
We should be able to read and write the flash using kernel functions:
- sceNandReadPages to read from flash
- sceNandWritePages to write to flash

ZX-81 asys he intends to add "me" features to his gba emu once the new eloaders out.
This is truely a great day for all psp users 1.00 to 2.60. I think everyone will benfit from this.

[counterwise]

yesssss
yesssss
yesssss
MODCHIP **** YOU!
i actually went jumping around after reading it phoned my brother and drank 1,5 liters of ice tea at the tempature 2 degrees celcius...now im cold
this is what ive been whaiting for for allmost half a year since i bought my psp and got a freaking 2.01!

[plasmaballs]

Very nice work indeed, top marks to hitchikr lets just hope a downgrader is possible or at least full intigration in to .97 eloader, either way good to have Fanjita back on the case. Good luck guys...!

As far as I know, if you have full kernel access then you will be able to access the flash.

Excuse me if I have got this wrong but I thought the way Sony "patched" it was that you could no longer access flash0 even with full kernel access after the 1.5 firmware.
You can still access flash1 AFAIK but this doesn't obviously give you the sort of options that you'd really want.

You may well be right, I haven't really researched about it much.
This is a shame because it was such a nice idea -- being able to go to any firmware between 1.00 and 2.60 whenever I wanted.
It was a bit too good to be true...

I would test out my idea trying to access flash, but I only have one PSP and that has firmware 1.00.
I'm not going to risk updating to 2.60 just to test it with a high possibility that I'm wrong and I won't be able to return to fw 1.00.
