Coldbird may be wrong, or it should be possible to add the missing support directly in the HEN.
Anyway I'd like to know what exactly TOcean did.

I tried to do that in a PSP in 6.31 to 6.20 but it didn't work, when i load the update, it just shuts down
does this only works on 6.36?

I'm sorry, I don't really understand what to do here...
Should I put the downloaded EBOOT.PBP file from the first post onto my PSP to downgrade?
Or do I just run the Sukkiri exploit and run the 6.35 updater from the XMB?
(I'm kind of a noob at hacking PSP's...)

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.

[/quote]Sony, being as sneaky as they are decided to do a rather interesting move. As researched by Coyotebean, Sony started enforcing using a public key method of verifying KIRK data and removing the ability to load the old types of data. As they did this, firmware 6.30+ cannot decrypt the updater and the PRX inside and therefore cannot use the index.dat spoofing to downgrade.

This application does the simple job of rebooting into the updater with a PRX that allows the updater to decrypt. A PRX that uses the pspdecrypt source and index.dat spoofing, nothing fancy.[/quote]
The best thing about this signature is that by the time you realise it doesn't say anything worthwhile it's too late to stop reading it.
