Here is a step by step guide for installing the newly released 3.90 M33. Please note that you must be running 3.52 M33-3, or higher to begin this installation. Do note that if you're already running 3.80 M33 and have a WiFi connection, you can simply update to 3.90 M33 by selecting Network Update from the PSP XMB.

Installation Guide

First grab the 3.90 M33 files and extract them.

1. Copy the UPDATE folder contained in the archive to X:/PSP/GAME

2. Download the 3.90 EBOOT, and then place it in X:/PSP/GAME/UPDATE

3. Navigate to the Game menu on the PSP and execute the program, it will not run unless there is 78 percent battery free.

4. Press X and the update process will start. Yes it may look similar to a regular Sony update but don't worry!

5. Once finished, the updater will ask you to press X or O to reboot. You MUST do this, otherwise you'll end up with a brick.

6. You've successfully installed 3.90 M33!.

Sony have disabled the Skype function for Japan region units, since the microphones aren't available there yet.

But custom firmware has an option to change region in the recovery menu, so that may work.

Mine PSP is 2000 japan as well.
Which means if i want to use skype, i just have to change the region to other country, then the skype will be available? I just bought my PSP Slim and feel sad when Sony announced that japan model not supported with skype:(

Yes it should work. Can't tell you for sure since I don't have a Japanese unit. But if I change my region to Japan, then the Skype icon goes away. So that's likely the only setting preventing it from showing.

U mean u want to format after update to 3.90m33?
Hold R when u boot up your psp, then simply go to advance > format flash1 and reset, wait for a while then everything will be reset. :smile:

No he meant that if he bricks it he want to reflash it. I have no idea, but try downgrade to 1.5 (WARNING!!: Change your language to ENGLISH before downgrade, or it'll be brick anyway when downgraded)then update to 3.52 M33 then a patch. After that you can upgrade to 3.90 M33 again. If you use pandora you don't have to worry about changing the language.

But if you are PSP slim, do not downgrade to 1.5 as Slim doesnt have 1.5 kernel (future time maybe, if Tima Machine by DA complete :p). Use pandora v4 to update to 3.80m33-5 and upgrade to 3.90m33.

Is it a new function so you dont have to download those update? Please explain

If you hold R during bootup and enter the configuration mode "Use M33 Network Update" should be enabled. What this does is download the latest M33 update from dark-alex.org when you select the Network Update option.

You can create a Pandora battery on 3.80 M33-5. Here's a guide on how to do it:

Though I recommend you buy an extra battery just for Pandora, so that you can always restore your PSP's firmware if something goes wrong.

do i have to put a new memory stick?
No, all it does is install some files to your memory stick. So, after you create a Pandora, the files can stay on there and you can continue using the MS as normal.

It write on the readme that we must use 3.80 SoNY E.Boot and rename it with 3.90.PBP

is that correct to use 3.80 EBOOT? or 3.90 EBOOT was available.. thx:blushing:
no, use the 3.90 EBOOT.
