Downgrader for FW 6.31/6.35 to Firmware 6.20 Released!


Davee's 6.31 & 6.35 to 6.20 Fw downgrader.

Davee has released a signed 6.31 & 6.35 to Firmware 6.20 downgrader for those that want to switch from 6.31 HEN or 6.35 HEN to use Total_Noob’s 6.20 TN HEN. Downgrading is risky business, so remember if you do decide to take this path and downgrade. We’re not responsible if you brick your PSP!

One thing to remember 6.20 TN-D is on the way, this will have POP’s support (PSX) 6.3x HEN developers may or may not be adding PSX support in later releases…

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.
