Coldbird: Coldbird: Downgrading is not possible with 6.35
[Image: psp-downgrader-logo-425.jpg]
Coldbird said that Downgrading wit Firmware 6.35 isn't possible because Sony removed the possibility to run old updaters in firmware 6.35.

Quote:No you can’t downgrade. In fact this isn’t even a problem with 6.35 PRO, but with Sony.

Sony removed Updater Kernel Module Support for old Kernel Updaters in 6.35, so… once you go 6.35 – you don’t go back.

That’s it basically.

Downgrading may not even be needed anymore, once devs start making things using sony's private psp keys.

Then what about 6.31 ? Any chance of a downgrader since 6.20 TN-B is more stable right now ?

Well, i bet that if you litterally forced it to downgrade (ie, creating a flasher) it might be possible, unless i totally missed the point

100% correct, there is no need for a downgrader. But, For the PSP they only have the user mode keys, most homebrew is kernel mode. So, to make things work like they do now, create a good exploit and sign it. It shouldn't be hard to make a CFW this way. Simply singing homebrew on the PSP will not work for most homebrew.

Couldn't future firmwares just patch the exploit then?

If the UPDATE folder is treated specially, maybe a homebrew launcher which runs in the UPDATE folder, which can then run homebrews in kernel mode?
IDK much about how the PSP works internally though.
