PSP/ME CFW

Minimal Edition, neur0n's closed source custom firmware. It was written entirely from scratch, and comes in permanent (cIPL) and temporary forms. From neur0n's PSP Stuff.

Unique Features

Support for some legacy 1.50 homebrew using Dark ALeX's LEDA plugin.
Adds a built in Speed up MS access function, which improves performance when reading from the Memory Stick. Faster than Dark AleX's 3.71 Fatmsmod.

Install OFW 6.60

Method 1: Connect to Wi-Fi. From the XMB (main psp menu), run System -> Network Update to install OFW 6.60.

Method 2: Download OFW 6.60 from Sony's site, and extract the file. (There are two different versions for PSP and PSP Go!)
Copy EBOOT.PBP to PSP/GAME/UPDATE/
From the XMB (main psp menu) run the update from Game –> Memory Stick.
You have successfully installed OFW 6.60.

Minimal Edition Installation

ME CFW is a Permanent CFW. It only works on models capable of cIPL flashing.

Download ME 1.8, and extract it.
Copy the entire contents of the extracted folder to the root of the memory stick.
Go to Game -> Memory Stick and run the ME Installer for 660.
Press X to install. Your PSP will then restart.
6.60 ME is now installed on your PSP.

To uninstall ME CFW, run the ME Installer for 660 and press Square.

Light Minimal Edition Installation

LME CFW is a Temporary CFW that works on all PSP Models. Despite its name, it is functionally equivalent to Minimal Edition.

Download LME 1.8, and extract it.
Copy the entire contents of the extracted folder to the root of the memory stick.
Go to Game -> Memory Stick and run the LME Installer for 660.
Press X to install. Your PSP will then restart.
Go to Game -> Memory Stick and run the LME Launcher for 660. Your PSP will restart, again.
6.60 LME is now installed on your PSP.
Once your PSP completely runs out of power, custom firmware will be uninstalled.
Now just run LME Launcher for 660 to restore it.

- To uninstall LME CFW, run the LME Installer for 660 and press Square.
- If the LME Launcher 660 app displays Load error -> 0x80010002 and shuts down, run LME Installer for 660 again to restore the needed system files.

6.20 Permapatch

[[#ref_This method is only for people who absolutely cannot wait three seconds to recover CFW when the PSP runs out of power. Otherwise, we strongly recommend using LCFW, an easier method where there is no risk of bricking your PSP!|^]]

On the 6.20 firmware, there is a unique exploit that allows permapatching on some newer PSPs.

Don't worry about issues with using an older version; the features have mostly been backported, and 6.20 LME 2.3 uses a convenient exploit to run 6.60 ISOs.
