Current latest firmware is 3.90-3 m33
1.50 kernel for 3.90 m33 released, only by manual updating, no network update thing for it.
Instructions listed here will reflect the most widely used Custom FirmWare (CFW). Other CFW exists with different authors, for example the HX series.
IMPORTANT NOTE
This forum, nor I, nor any of the other moderators will take responsibility for what you do to your PSP. Upgrade at your own risk. Great care has been taken in making sure instructions are correct. If you do brick, you are unlucky. Refer to the unbricking thread in this forum.

Upgrading to newer firmwares
Both the Phat and the Slim uses the same CFW, thus I will be listing instructions as though they are the same. I will make it clear when things are different. The Slim CANNOT use the 1.50 kernel.
Disable all plugins as a precaution before upgrading. If you don't know what plugins are, it is likely you have none, with none to worry about.
Charge your battery to at least 78%. Connect your PSP to the charger when upgrading.
There are several paths to take in upgrading your PSP, depending on its original state. To find out your PSP firmware version, go to System Settings > System Information.
1) Your PSP has official firmware, meaning it's firmware is untouched except by Sony's hands. Your firmware version should be a number without any extra tags like m33, OE, IE, LE or HX.
2) You have a PSP thats CFW-enabled, but not the latest firmware.

Upgrading to 3.71 m33-4
Refer to this guide if you are on official firmware: Unbricking your PSP
It will work on unbricked PSPs too.
You have a Phat with firmware lower than 3.52 m33-4
You need to at least be on 3.52 m33-3 or 3.52 m33-4 to upgrade to 3.71 m33-4. If you have a CFW that is not from the SE/OE/m33 series, recover to 1.50 first. I'm not sure if there will be any conflicts during upgrading.
1) Download 3.52 m33. Extract all the files.
Readme file in folder:
PSP 3.52 M33 Installation
1 - If you are under official 1.50 PSP firmware, copy kxploitpatcher and kxploitpatcher% folders from "1.50only/" of this download to your "ms0:/PSP/GAME/ " and use it.
2 - Once done it, or if you are under any Special/Open Edition/M33, copy M33CREATOR folder to your "ms0:/PSP/GAME " (1.50fw) or "ms0:/PSP/GAME150 " (SE/OE)
3 - Download official 3.52 eboot, rename it to 352.PBP and place it on "ms0:/PSP/GAME/M33CREATOR/" or "ms0:/PSP/GAME150/M33CREATOR/"
4 - Download official 1.50 eboot, rename it to 150.PBP and place it on "ms0:/PSP/GAME/M33CREATOR/" or "ms0:/PSP/GAME150/M33CREATOR/"
5 - Go to Games/Memory Stick on your PSP, and execute "3.52 M33 CREATOR". Once finished, it will go back to the XMB.
6 - Go again to Games/Memory Stick on your PSP, and execute "3.52 M33UPDATE". You'll have to press X to agree to the installation.
7 - When finished, press X to shut down and reboot manually.
8 - Enjoy your 3.52 M33
2) Download 3.52 m33-4 update and extract the files.
3) Copy the PSP folder to your memory stick, merging the folders.
4) Run the update and follow instructions onscreen.
5) Congratulations being halfway there !
You have a Phat with 3.52 m33-3/4 or a Slim with a CFW lower than 3.71 m33
1) Download 3.71 m33 and extract.
Readme file in folder:
- Copy the UPDATE directory into /PSP/GAME/UPDATE and copy the EBOOT.PBP of the 3.71 Sony updater
there but with name "371.PBP". Note: the program will not even show if you copy it to a different folder than that.
- If you are in the fat psp, make sure you have configured the psp to run the game folder in the 3.XX kernel.
- Execute the program, it requires 78% of battery. If you have idstorage corrupted due to a downgrader, the program
will ask you to correct it automatically so the update can continue.
- Press X, and the Sony updater will begin. Sit and enjoy while Sony code installs 3.71 M33
- When finished, the updater will ask you to reboot (pressing X or O). DO IT. Do not skip this step
shutting down the psp by yourself, or you'll end with a brick.
- You should be now in 3.71 M332) Download 3.71 m33-4 update and extract.
3) Copy the UPDATE directory to /PSP/GAME/
4) If your PSP is a Phat, make sure the kernel is set to 3.71 in the recovery menu.
5) Run the update, follow instructions onscreen.
6) Congratulations on 3.71 m33-4 !
Adding the 1.50 kernel to your Phat
THIS WILL NOT WORK ON THE SLIM, HOWEVER HARD YOU TRY.
This update adds the 1.50 kernel to your Phat, since the 3.71 m33 update does not do so due incompatibility with the slim. (Phat users, curse the Slim
)
You can decide not to do the addon, if you don't use 1.50 homebrew, but a bugfix regarding returning from sleep mode is included in the update. Not sure if it's in the 3.71 m33-4 update though. I recommend doing this update, unless you need that precious flash0 space for your themes/experiments.
1) Download 1.50 kernel addon v2 and extract.
2) Copy the eboot.pbp file to /PSP/GAME/UPDATE/.
3) Download the 1.50 eboot, name it 150.PBP and place it in the root of your memory stick.
4) Make sure your kernel is set at 3.71 in the recovery menu.
5) Run the update.[/b]Edited by FrozernFire 16 Jan `08, 5:27PM
