So you have a PSP and you want to try out this thing called "homebrew" you've been hearing so much about. Problem is, you're still on official Sony firmware. What to do? Well, read this guide for starters. Today we'll be tackling how to install custom firmware on PSPs running anything from OFW 1.50 to OFW 3.50.

The first four tutorials below are about downgrading to 1.50. If you're already at firmware 1.50, skip to the end. If you're currently running Sony firmware not listed in the tutorials below, don't fret. Just update to the covered OFWs and follow the instructions we've outlined. For example, if you're on OFW 1.51, update to 2.00. If you're on 2.60, update to 2.80.

So, without further ado, let's get started.

OFW 2.00 and 2.01

Required downloads:

Optional download:

OFW 2.01 Update

Step 1: Extract the eLoader folder in eLoader_v1.zip to the GAME folder of your PSP.

Step 2: Extract the PSP folder in 201DG.zip to the root of your memory stick.

Step 3: Extract the 1.50 update to PSPGAMEUPDATE. Note that you might have to create the UPDATE folder yourself.

Step 4: Run the downgrader via eLoader. To downgrade, choose the v1.00 option.

Step 5: Once you've downgraded to v1.00, run the v1.50 update.

Alternative downgrading method for OFW 2.00:

Required downloads:

Step 1: Extract the MPH Downgrader to the root of your PSP's memory stick.

Step 2: Extract the 1.50 update to PSPGAMEUPDATE. Note that you might have to create the UPDATE folder yourself.

Step 3: Go to Photo -> Memory Stick. YouÂ’ll see a black screen with some numbers (see pic below). Wait 30 seconds then restart your PSP.

Step 4: Run the OFW 1.50 update. YouÂ’ll see an error (first pic below) at the end of the update, but this is normal. Restart the PSP manually. When you encounter another error (second pic below), press O to restart.

OFW 2.80

Required downloads:

Optional download:

OFW 2.80 Update

Step 1: Copy the contents of the MS_ROOT folder in ta82downgrader.zip to the root folder of your memory stick.

Step 2: Copy the 1.50 update eboot to PSPGAMEUPDATE. Make sure it's named UPDATE.PBP.

Step 3: Install and run HEN 2.80.

Copy all the files inside the MS_ROOT folder in hen280.zip to the root folder of your memory stick.
Go to the PHOTO viewer on the PSP XMB and enter the HEN_280 folder. If your PSP freezes, just reboot and try again.
When the program runs, you'll see either a red or blue screen.

A red screen means that the files couldn't be written to flash. If you get this result just try again.

Blue screen - Image 1

A pale blue screen means that the files were written successfully and HEN is active. The XMB will reboot afterwards. Note that the pale blue screen will appear again every time the PSP reboots with HEN active.
Test that HEN is working fine by running one of the bundled sample applications.

Step 5: If your PSP has a TA-082 motherboard run the 2.80 idstorage changer. Your PSP's battery has to have at least 75% charge for it to run.

Step 6: Run Update X.YX. Again, your PSP's battery has to be have at least 75% charge for the update to run.

Step 7: If all went fine, you'll receive a blue screen telling you to press O. Do it reenter your settings. You are now at 1.50.

OFW 3.03

Grand Theft Auto: Liberty City Stories - Image 1

Required UMD game and downloads:

an unpatched copy of Grand Theft Auto: Liberty City Stories
Noobz 3.03 to 1.50 downgrader
OFW 1.50 Update

Optional download:

OFW 3.03 Update

Step 1: Update to firmware 3.03. If already have this firmware then proceed to step 2.

Step 2: Open the 3.03 downgrade file and copy the contents of the MS_ROOT folder to the root of your memory stick.

Step 3: Open the 1.5 update and rename the EBOOT.PBP to UPDATE.PBP then copy it to PSPGAMEUPDATE. Make sure not to overwrite PSPGAMEUPDATEEBOOT.PBP

Step 4: Load your unpatched version of Grand Theft Auto: Liberty City Stories. It should get to loading save game, clear the screen, then the screen should fill with a light blue color and then reset the PSP. If this does not happen see below.

Check that HEN is running by going to system settings then System Information and it should show up as system version 303 HEN
If it is showing up as 3.03 HEN then go to the memory stick and run the X.YZ update

Step 5: Before the downgrader does anything to your PSP it will ask for you to agree to what it is doing. If you no longer want to continue press the Right Shoulder Button (R-TRIGGER). If you have agreed to start the downgrade do not unplug the PSP.

Note: If you have an unpatched TA-082 or higher motherboard, you will be prompted to allow the downgrader to patch your motherboard so it can be safely downgraded. The downgrader will not let you proceed without patching, if your motherboard requires it.

Step 6: Once finished the PSP will ask you to press X. After pressing it will reset it self.

Step 7: If a blue screen comes up saying that the settings are corrupt press X or O to continue.
