PSP Firmware 6.39 Downgrader 3.1

6.39/6.38/6.35/6.31 -> 6.20/6.35 Downgrader By Davee, ported to 6.38/6.39 by some1

v3.1: Fixed idiot bug for 6.38 I created when adding 6.39
Instructions:
If you have anything lower than an 07g place the 6.20 update in PSP/GAME/UPDATE.
If you have an 07g or an 09g, place the 6.35 update in PSP/GAME/UPDATE.
No screenshots added because it’s only text (splash screen as pic1).
Important note: You run the application at your OWN risk. I am not held accountable if you **** up your PSP.
Another important note: After you downgrade to 6.20, you will get a BSOD (saying that your system information is corrupted), this is OK, just click circle to reset your system information and you will be back to normal.

[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.
6.38/6.39: *add when source is released*

[READ]
You run the application at your OWN risk. I am not help accountable if you PSP ****s up.
