Upgrading Your PSP from 3.52 M33 to 6.60: A Complete Modern Guide
If you have a PlayStation Portable (PSP) still running the legendary 3.52 M33 custom firmware, you are holding a piece of handheld history. Released by Team M33 nearly two decades ago, it was the gold standard for its time. However, to play modern homebrew, enjoy better PS1 compatibility, or use the latest plugins, upgrading to Official Firmware (OFW) 6.60 (and subsequently a modern custom firmware like PRO or ME) is essential.
Updating from such an old version requires specific steps to avoid common "version spoofing" errors or "DADADADADA" update failures. 1. Preparation: The Hardware Checklist
Before touching any software, ensure you have the following:
A Charged Battery: Your PSP must have at least 78% charge. If it dies during a firmware flash, you will brick the console.
AC Adapter: Keep the PSP plugged into a wall outlet throughout the process.
Memory Stick: A Pro Duo stick or a MicroSD to Pro Duo adapter with at least 64MB of free space. Mini-USB Cable: To transfer files from your PC. 2. Step 1: Cleaning Up 3.52 M33
Old M33 firmwares sometimes had "version.txt" files that tricked the PSP into thinking it was on version 9.90, which blocks official updates.
Check for Spoofing: Completely shut down your PSP (hold power for 3 seconds). Hold the R-Trigger and turn it back on to enter the Recovery Menu.
Configuration: Go to Configuration and ensure "Use version.txt" is set to Disabled. Exit: Select Back and then Exit. 3. Step 2: Updating to Official Firmware 6.60
You cannot jump directly to modern custom firmware from 3.52 M33; you must first return to official Sony software.
Download OFW 6.60: Find the official Sony 6.60 EBOOT.PBP from reputable archives like ConsoleMods. Transfer Files: Connect your PSP to your PC via USB. Navigate to the PSP folder, then the GAME folder. Create a new folder named UPDATE (all caps). Place the EBOOT.PBP inside: ms0:/PSP/GAME/UPDATE/EBOOT.PBP. Run the Update:
Disconnect from the PC. On your PSP XMB, go to Game > Memory Stick. Launch the PSP™ Update ver 6.60.
Follow the prompts to install. Once finished, your PSP will reboot into official version 6.60. 4. Step 3: Installing Modern Custom Firmware (PRO-C or ME)
Now that you are on 6.60, you can install a modern, "portable" (temporary) or permanent CFW. PRO-C2 is highly recommended for its compatibility. How To Update Your PSP TO 6.61 Official Firmware
The PSP-1000 and PSP-2000 models running 3.52 M33 are currently on a "legacy" custom firmware (CFW). Upgrading to 6.60 (or 6.61) provides modern game compatibility, better plugin support, and access to the PlayStation Network (PSN) infrastructure. 🛠️ Prerequisites Hardware: A PSP-1000 or PSP-2000 (Non-v3 motherboard). Battery: At least 78% charge (or plugged into AC power). Storage: A Memory Stick Pro Duo with at least 100MB free. Files: Official Firmware (OFW) 6.60 EBOOT.PBP. M33-4 Update (if currently below 3.52 M33-3). 6.60 ME-2.3 (Minimum Edition) or 6.60 PRO-C2 installers. 📈 Phase 1: The Bridge Update (3.52 M33-4)
You cannot jump directly from 3.52 M33 to 6.60 because the internal updater lacks the necessary keys to recognize newer firmware. You must first ensure you are on 3.52 M33-4. Check your "System Settings" -> "System Information." If it says "3.52 M33," you must install the M33-4 update. Place the update files in PSP/GAME/UPDATE. Run the update from the XMB (Cross Media Bar). 🔄 Phase 2: Installing Official Firmware 6.60 Upgrading Your PSP 352 to M33 6
Once on M33-4, you must return to a clean official base before applying the modern CFW. Download the 6.60 OFW EBOOT. Rename it to EBOOT.PBP if it isn't already. Place it in ms0:/PSP/GAME/UPDATE/. Run the update.
Note: If you get a "Version 9.90" error, go to the VSH Menu (press Select), change "USB Device" to "Flash 0," connect to a PC, open vsh/etc/version.txt, and change "9.90" to "3.52". 🚀 Phase 3: Installing 6.60 ME-2.3 (Permanent CFW)
Since your device is already running M33, it is a "fully hackable" model. The ME (Minimum Edition) firmware is the best choice for permanent installation. Download the 6.60 ME-2.3 (or 6.61) installer. Place the UPDATE folder into ms0:/PSP/GAME/. Launch the installer from the Game menu. Follow the on-screen prompts to flash the firmware. The PSP will reboot into a permanent 6.60 ME state. ✨ Benefits of the Upgrade
Game Support: Plays all late-cycle UMDs and ISOs without patching.
Homebrew: High compatibility with modern emulators (SNES, GBA, PS1). Stability: Improved Wi-Fi security protocols (WPA).
Recovery: Access to an advanced Recovery Menu by holding R on boot. If you'd like to proceed, I can help you:
Identify if your PSP is a 1000, 2000, or 3000 model to ensure you use the right files. Find the specific download links for the 6.60 ME-2.3 files.
Troubleshoot the "Version 9.90" error if you encounter it during the process.
