[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

[READ]
You run the application at your OWN risk.
If you're too lazy to read it then basically, you copy over the PSP folder to your PSP and put the 6.20 update to "PSP/GAME/UPDATE/EBOOT.PBP".
