Points: 0.52 Donate | | | Another Downgrade Idea...
This will only work provided we have the public key!!!
What if we could unsolder PSP's flash, read the data on a PC, modify the firmware and then re-encode it? We could add our own exploit by just changing a few bits and then have it flashed again! Then use the exploit we inserted to downgrade and bla bla bla...
I think the firmware is decoded on the chip. If this is possible we could change the version number of an 1.5 firmware and reencode the whole thing again with the public key but I think this goes a little far from true...
Let someone who knows how to code answer on this... And PLEASE don't flame... I just dropped an idea!

and if we did we could downgrade anyway ad we would just make our own firmware and code it with the key.

Points: 1.02 Donate | | | ive given the greatest idea for right now and no one seems to notice... theres no use tearing open your psp and theres no use of the gta exploit to make a downgrader
you can simply make a downgrader with the update eboots...
i dont want to explain how to do it because ive done explained so many times and no one seems to notice |

2: open the psp
3: get an Eprom burner
4: carefully remove the flash mem
5: burn whatever you want on it
6: carefully put it back together

| Yeah,yaeh... It is that simple, what for that moment we haven`t even a bit of success with downgraders and all attemps was failed... Just try to make it by yourself, if you are saying what its THAT simple to do.
