Install 6.20 TN-A Hen and Prometheus ISO loader on your PSP

Thanks to the efforts of Wololo and Liquidzigong, PSP-3000, PSP-2000 with TA-v88v3 motherboard or PSP Go owners can now have custom firmware (well it’s pseudo-cfw.. it’s actually HBL + ISO loader but let’s call it that for convenience’s sake) installed on their PSPs via 6.20 TN-A Hen and Prometheus ISO loader. With the 6.20 TN-A and Prometheus ISO loader, you can now run PSP games off your memory stick for free :).

Requirements for 6.20 TN-A Hen and Prometheus ISO

Update: Signed 6.20 TN-C Hen is out so if you want to update or are having troubles installing 6.20 TN-A Hen on your PSP, I recommend follow this guide.

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

  • Extract the Patapon 2 Demo onto your PC
  • Copy the folder (UCUS98734) into x:\PSP\GAME (x is your memory stick or the PSP Go‘s storage)
  • Extract the 6.20 TN-A Hen file onto your PC
  • Copy it’s contents directly onto your PSP.  This contains both the homebrew loader and the exploited save data.
  • On your XMB, Run the Patapon 2 Demo
  • If you see the screen below. Select ‘No’ to proceed
  • Select Yes at this screen to proceed
  • Select Continue
  • and load the save file. Do note that the icon may be different.
  • Once the game has loaded, Press [R Trigger] to load HBL Menu
  • Your PSP will now load the HBL menu as seen below. Select Hen to load the 6.20 TN-A HEN on your PSP. A bit of warning though, selecting this option will cause your PSP screen to be blank for a moment then reset to the XMB. This is normal so don’t panic.

    If you get a “Warning, memory leak!”, again don’t panic, this is normal.
  • Once you’re back on the XMB, press “select” to make sure the TN Hen menu displays correctly.
  • Follow this guide on how to install the Prometheus ISO loader on your PSP: Installing the Prometheus ISO loader on your PSP.
  • Enjoy your Free PSP Games :).

Important Note: Be sure to check the Prometheus ISO loader compatibility guide
Important Note: You need an ISO folder in your PSP’s memory.  Simply create one and dump your PSP ISOs/CSOs there.

Below is a video of the hack for skeptics out there:


If you’re not on 6.20 OFW and want to update your PlayStation Portable to accommodate 6.20 TN-C follow these instructions: HowTo: Upgrade your PSP to 6.20 OFW.

If you’re on a different firmware, you may want to take a look at other Hen installations:

    is it recommended to update from 5.03 using ChickHEN hack to this one

    • atmaxplorer sylv3rblade January 2, 2011 Reply

      If you’re still on 5.03, just use chickhen and install the cfw for that. 6.20 is still a work in progress

      In this case you upgrade, the link for the updater to 6.20 is within the post.

        but he says “1000”, meaning fat. he should instead use a pandora battery right?

    i have a question to ask you guy, i try to downgrade my psp 1000 using 6.20 TN-B. to downgrade to 5.03 they need 5.0 version.tx . if i am trying to downgrade to 1.5 what version.tx do i need.

    • atmaxplorer sylv3rblade January 15, 2011 Reply

      umm 1.5 OFW? Why would you want to do that?
      At the moment, since Hellcat’s recovery is still in the process of getting updated to support 6.xx firmware, you can downgrade via a Pandora battery.
