6.35/6.31 -> 6.20 Downgrader By Davee

[What does it do?]
Allows users who are incontent with their firmware to downgrade to 6.20 using the Sony Updater.

[How do I use it?]
Copy the "PSP" folder to your PSP. The downgrader is "signed" and can be launched from OFW XMB. You need to copy the 6.20 update to PSP/GAME/UPDATE/EBOOT.PBP and for PSPgo it must be the eflash it is placed on. After setup run the downgrader and follow the onscreen instructions.

[What does it technically do?]
It uses the utility/power exploit to gain kernel access and reboots into the updater with a special PRX running. This PRX uses the pspdecrypt functionality to decrypt the updater PRX when needed. This allows the updater to boot in the newer firmwares.

[I'm a dev, sup?]
The source is in the SRC folder... if you even read this. Use the source for referencing, updating, snipping etc, remember where you got it from. Also, there is a HBL Sukkiri version, see the "Makefile" for info on the various modes, etc

I know this is probably the wrong section but less people visit the downgrader section and i really want to get the news to people who are on 6.35/6.31

I hope the mods Understand
