I’ve upgraded my PSP 2000 just recently, from CFW 5.50PRO to 6.60-C PRO, successfully without using Pandora Battery and hellcat. But it’s safer to do this with a Pandora Battery in case you brick your PSP. This blog post will guide you how to install a custom firmware (CFW), specifically Prometheus, as I’ve never encountered any problems ever since. And as of now, the latest PSP firmware is 6.60.

Please take note that I will not be held responsible if you bricked your PSP. Do this at your own risk.

First let’s determine which PSP are you using:

PSP 1000

PSP 2000



PSP 3000



PSP Go (N-1000)



PSP Street (E-1000)


Is your PSP one of those? Then you can now proceed reading on the CFW guide. If you don’t see your PSP system listed above, then I’m afraid there’s no CFW available for it yet.

ATTENTION PSP 2000 owners:

Again, this is for PSP 2000 owners. If your PSP is other than PSP 2000, then please skip this guide to avoid confusion.

You need to check the DataCode of your PSP 2000, which can be found in your PSP’s battery compartment. Remove the battery, and you should see something like this:

If your PSP has 8C data code and above, your PSP is listed as PSP2000v3.

If your PSP is below 8C, your PSP is listed as PSP 2000.

If you can’t find your PSP’s datacode, use the LME CFW and check the motherboard by running PSPident 0.75–Just place it inside X:/PSP/GAME folder and run it on your PSP. You should be seeing something like this:

If the motherboard model isTA-088v3, you have to use the Fast Recovery app, not the CIPL Flasher (will be explained further below).

If PSPident indicates any other motherboard type, then it’s safe to use CIPL Flasher, which is a permanent cfw patch.

“Why?” You might ask. It’s becauseTA-088v3 is a new type of motherboard that is similar to the ones in PSP 3000 models. If you run CIPL_Flasher on a TA-088V3 motherboard, or in PSP 3000 models, your PSP will get bricked.

Still confused?

PSP 2000 series date codes:
  • 7C – Hackable
  • 7D – Hackable
  • 7(with any later letter) – Hackable
  • 8A – Hackable
  • 8B – Hackable
  • 8C – Unhackable
  • 8D -Unhackable


Make sure that your firmware is below 6.60.

Download the official Sony firmware 6.60 (OFW).

For PSP Go users, download firmware 6.60 for Go.

Unzip the file, then copy and paste the folder to the root of your PSP’s memory stick.

If you’ll run the OFW on 3.XX OE CFW, it will give you a DADADADA error.

CFW 5.50 ERROR “Its already version 9.90 installed, no ‘update’ necessary”

Upgrade to CFW 6.60 PRO-C Fix 3

From 6.60 B9 PRO, you can update to the latest fix from Prometheus. As of now, the latest is 6.60 PRO-C fix 3:

The process of installation is the same as the instructions above on how to install 6.60 B9 PRO, just download6.60 PRO-C fix 3.

Installing CFW 6.60 PRO-C Fix 3 for PSP 2000V3, 3000, PSP Go, and PSP Street:

You don’t need to install 6.60 B9 PRO. You can run the latest release from Promotheus, which is currently 6.60 PRO-C fix 3. However, there’s no permanent patch for the mentioned PSP models.


  1. Make sure you have downloaded the Official Sony 6.60 Firmware. Search for the download link above.
  2. Download this 6.60 PRO-C fix 3, again, for PSP 2000V3, 3000, PSP Go, and PSP Street.

*You can delete the PRO Updater, but keep the Fast Recovery.

*Again, there’s no permanent patch for PSP 2000V3, 3000, PSP Go, and PSP Street. Run the Fast Recovery toolONLY if you reboot/shutdown your console, not when you put it into sleep mode. Know the difference. Running the Fast Recovery tool only takes 5 seconds, fyi. The Fast Recovery tool will temporarily patch your PSP, allowing you to play your downloaded games.

So there you have it. Your PSP is now running the latest CFW 6.60 PRO-C Fix 3! Enjoy!
