3.80 M33 Ultimate Thread!!

Okay, this must be installed from atleast 3.52 M33. 3.52 M33 can only be installed from an existing CFW, which can only be installed from 1.50 or using a Pandora. IF YOU HAVE AN UNMODIFIED PSP WITH OVER 3.50, THEN SOL!!!!! For more details READ STICKIES!!!!

Downloading File

Download from Mirror

CRC:78874AED

Preparing Files

Unzip the archive. WinXP, Vista and most Linux (Including (K, G,X)Ubuntu have built in ZIP support. For Win98 and older use 7-Zip File Manager. Take the 3.80 M33 Eazy Installer - MPG187 folder and put it on let's say the desktop.

Upgrading to 3.80 M33

From the folder we copied extract the "1 3.80 M33" folder and make your Memory Stick's Root Folder match it. So there should be PSP/GAME/UPDATE and the files in that folder.

Exit USB or Take Card out of Card Reader and put back in PSP. In xMB goto memory stick game. Run the update. It will have a black screen with White Writing and then goto the Sony 3.80 M33 updater. From here act like installing OFW. IT WILL STILL INSTALL M33 AND NOT OFFICIAL FIRMWARE!!

1.50 Homebrew

As of 3.60 M33 there is no 1.50 kernel. The reason is at the current time it cannot be ran on Slim PSPs. So phat PSP users have to install it seperate. Slim users upgrade Homebrew to the new kernel (makes use of Slim's extra memory!) or use Noobz team eLoader which is a program that runs under the new kernel (including slim) which attempt to run 1.50 in user mode which runs most homebrew (things that emulate UMD/ISO dont work).

If you own a slim or dont intend to use 1.5 homebrew skip this section. Other wise:

Make the "2 1.50 Kernel" folder reflect the root just like in the previous step. Once again from the xMB run the file. This will remove Korean Font and Location free player (Oh no the most commonly used features, no thing that increases homebrew compatibility is worth that!) to free space so it can add the 1.5 kernel.

Upgrade to 3.80 M33-4

At the time I am making this the latest version is 3.80 M33-4 (3.80 M33-2 and 3 were made but I wasnt around, they are skipped, if you need them goto dark-alex.org).

Once again make the folder to the root, this time use the "3 M33-4 Update" folder. In that folder is PSP/GAME/UPDATE so we have to delete the UPDATE folder from the first section/3.80 M33 upgrade.

Save Time

Since the 3.80 M33 upgrade and M33-4 upgrade use PSP/GAME/UPDATE once has to use the first one, delete the folder and put the M33-4 files in, you can put on the 3.80 M33-4 update and the 1.50 kernel on the MS while on USB and then run them both, come back and then apply the M33-4 files and upgrade then.

Follow the same directions as 3.80 M33 except use "1 3.90 M33 Update" instead of "1 3.80 M33" and "2 150 Kernel" instead of "2 1.50 Kernel" (I guess I used the decimal that time!...)

As of now there are no updates so there is no "3 3.90 M22-x" folder!
