Install Signed 6.20 TN-C Hen + Prometheus ISO loader on your PSP

Total_Noob has released an update to 6.20 TN-A (and TN-B) fixing bugs and pushing quite a few features that merit an update.  What’s more interesting is that 6.20 TN-C is now signed, meaning it no longer needs to be run through the Half-Byte Loader and Patapon 2 demo exploit but rather it can be run on your XMB directly.

Now if you don’t understand the mumbo-jumbo indicated above, it simply means you can now easily run homebrew on your PSP by running a simple piece of software on your PlayStation Portable – at least as long as you’re on 6.20 OFW 🙂

If you’re already on 6.20 TN-A Hen, you can also follow the instructions below to upgrade to 6.20 TN-C.


  • A PSP-3000, PSP-2000 with TA-v88v3 motherboard or PSP Go with official firmware 6.20 installed. If you have a hackable PSP, I would recommend to install a permanent CFW like 5.50 GEN-D3.  If you’re not on 6.20, follow the upgrade guide for your PlayStation Portable on the troubleshooting part of the guide
  • Signed 6.20 TN-C Hen
  • Prometheus ISO loader | Mirror

Installing Signed 6.20 TN-C Hen and Prometheus ISO loader on your PSP

  • Extract the Signed 6.20 TN-C Hen file to your computer
  • Copy the PSP folder directly onto your memory stick or the storage of your PSP Go.
  • Go to your XMB, run the 6.20 TN-C Hen installer.  It will install then reboot to your XMB.  At this point, if you check your system’s current firmware version, it should give you 6.20 TN-C Hen
  • Once you’re back on the XMB, press “select” to make sure the TN Hen menu displays correctly.
  • Follow this guide: Installing the Prometheus ISO loader on your PSP.
  • Enjoy your Free PSP Games :).
