Upgrading a PSP from the legendary 3.52 M33 firmware to 6.60 is like waking a time traveler. In the late 2000s, 3.52 M33 (created by the famous developer Dark_AleX) was the gold standard for homebrew. Today, 6.60 is the preferred destination because it offers the best balance of modern game compatibility and plugin support. Why Make the Jump?

For many PSP enthusiasts, custom firmware 3.52 M33 (released by the legendary Team M33 back in 2007) represents the golden age of PSP hacking. It was stable, efficient, and opened the doors to homebrew, ISO loading, and plugins. However, time marches on. The PSP’s official firmware evolved significantly from 3.52 to 6.60, adding features like PlayStation Network integration, improved video playback, better security patches, and—most importantly—compatibility with modern homebrew and plugins.

If you are still running 3.52 M33, you are likely facing frustrating limitations:

• Incompatibility with newer games: Many later UMD releases require at least firmware 5.00 or higher.
• Outdated homebrew support: Most modern emulators (like DaedalusX64 for N64) and utilities require 6.60 or 6.61.
• No permanent patch options: Newer custom firmware (CFW) like 6.60 PRO-C or 6.60 LME offer permanent patches on all motherboard models (except the PSP Go and certain 09g models).

This guide will walk you safely, step-by-step, from the vintage 3.52 M33 to the modern standard: 6.60 PRO-C2 (or 6.60 LME). We’ll cover everything from backing up your data to troubleshooting common errors.
