6.20 TN-B HEN downgrading tutorials in video and text-only form


One of the big additions that Total_Noob introduced in 6.20 TN-B HEN is the ability to downgrade PSPs from OFW 6.20. Downgrading can be tricky, so to help those who aren't too familiar with how to do it here are a couple of tutorials.

Note: If you have a PSP Go, downgrading is not recommended.

This first one is a video tutorial from YouTube user kamenriderpsp. You'll need the following files for this:

6.20 TN-B HEN
HBL r109 for Patapon 2
Patapon 2 save game
Patapon 2 demo
5.00 version txt
Official PSP firmware 5.03

The 6.20 TN-B download already includes the first three items in the list above. You can get the Patapon 2 demo here, the 5.00 version txt here, and OFW 5.03 here.


If you'd rather go with a text-only tutorial instead of watching a video, here's one from PSP-Hacks. This involves using PSARDumper to make your own version.txt. You can download the latest PSARDumper release here. As with any downgrading tutorial, please be very careful when doing this as the possibility of bricking your PSP exists. If you're unsure of any of the steps, just stay on 6.20 TN.




  • Start 6.20 TN-B
  • Download the following files:
    • PSARDumper
    • The OFW (EBOOT.PBP) update that you want to downgrade to. PSP-Hacks has a comprehensive download list here.
  • Place PSARDumper in the PSP/GAME folder like you would any other homebrew and copy the OFW EBOOT.PBP to the root of your memory stick
  • Start PSARDumper and press circle
  • After the program finishes, connect the USB cable to your PSP and navigate to the folder F0, which should now be at the root of your memory stick
  • Copy /F0/vsh/etc/version.txt to /seplugins/version.txt
  • Go back to your PSP XMB and press select to bring up the VSH menu. Go to “Fake Index.dat” and change it to “enabled”. Next, select “restart vsh”
  • Copy the OFW EBOOT.PBP to “PSP/GAME/UPDATE/EBOOT.PBP”
  • On your PSP start the OFW installation as you would any other firmware update
  • After it finishes, the PSP will restart and a blue screen will appear saying that the PSP settings are invalid. Press circle and the PSP will restore default settings and restart. You now have OFW installed.
