I know this post is very much too late but it’s like obligatory to post the instructions on how to install the latest update. We’ll here it is (taken from DA’s instructions):

This update is a try to fix memory stick low speed since 3.80.

Instructions: Copy UPDATE folder /PSP/GAME/ and run.

If you come from a version prior to 5.00 M33, put sony update as 500.PBP in same folder, or let the program download it for you using a wifi connection.

Changes in 5.00 M33-5:

- A setting has been added to recovery, that, when enabled it may increase memory stick reading speed. (only on the psp, not in the pc).
By default it is disabled. If you installed 3.71 fatmsmod, do not use this setting, as its perfomance with 3.71 driver has not been tested.
Instead, reinstall 5.00 m33-4 using dc8 and update to 5.00 m33-5

Changes in 5.00 M33-6:

- Fixed a bug that made unbootable psp without memory stick or with a bad one.

The included file fat_comparison.html contains a comparison of perfomance between the 5.00 fat driver, the 3.71 one, and the 5.00 one with the speed up hack during the read of an iso.
The test was done on the game Valkyrie Profile in cso format in march33 mode. Other games, modes and applications different than iso reading showed similar results.

• Speed selected for umd/iso was not properly locked in some new games that used scePower_EBD177D6 instead of scePowerSetClockFrequency to change speed.
• UMD/ISO speed settings now apply to PSN games too.
• Fixed libupdown.prx connecting to dark-alex.org instead of sony when npsignin_plugin checks for a new version and m33 update is enabled.
• Iso file descriptor was not closed in driver deletion
• Added a shutdown command to vshmenu.

Requirements:

• Fat or Slim PSP installed with 5.00 M33-3 or lower. If you don’t have a 5.00 M33 yet, here’s a 5.00 M33 installation guide.
• USB Cable
• Computer

Instructions

1. Download the update via rapidshare or megaupload.
2. Unzip the file anywhere on your computer. Connect your PSP to your computer then copy the contents of the UPDATE folder to ms0:/PSP/GAME/
3. Go to XMB menu and then go to GAME>Memory Stick then run the Update
4. Wait for 5 seconds. Voila! You now have a 5.00 M33-4 PSP.

Got it? Enjoy.

• A bug was introduced in 5.00 M33-2 that made some games and homebrew not to work
• PSN version check is now automatically bypassed without need of touching any setting

So basically, 5.00 M33-3 is better and less buggy. And now onto the very easy installation guide.

The Requirements

• Your PSP installed with 5.00 M33-2 or 5.00 M33. Follow the 5.00 M33 here.
• USB cable
• Wifi - If you have wifi connection at home, you could do the update in one step. Just go the the Network Update on the Settings Menu and follow your instructions and your done.

The Guide

1. Download the update package from any of the following mirrors:
   Mirror1: http://rapidshare.com/files/156743814/500m33_3.rar
   Mirror2: http://www.megaupload.com/?d=J2B220F8
2. Extract the archived file to your computer.
3. Connect the PSP to your computer and copy the UPDATE folder to ms0:/PSP/GAME/
4. Go to your XMB and run the update
5. Follow on screen instructions and wait.

Although you could install this update directly from previous versions (3.71 M33 to 4.01 M33-2), I did write this guide for noobs.

Thanks to Dark Alex for the custom firmware.

So you went out successful from the bathroom. You are excited to return to your game when you find out that your brother is tinkering with your PSP and he just exited the game! What to do? You load your game but you have to go to all those monsters again, all thanks to your brother. But is he to blame? Good thing there’s PSPStates! You don’t have to worry about those things now. With PSPStates, you can save your game whenever you want.

PSPStates copies the data in the PSP’s memory to a save state image on your Memory Stick. You can then load that saved state back to memory and continue from it at any point like a Saved Game. And you don’t even need to use a save point. PSPStates was created by Dark Alex and you can download the plugin for 5.00 M33 at the following mirrors below:

Mirror1: http://rapidshare.com/files/154982316/p … s2_500.rar
Mirror2: http://www.megaupload.com/?d=HVZI6HRZ

You can read the installation guide from the readme.txt that comes with the package above. PSPStates only supports the PSP Slim with 5.00 M33 custom firmware installed.

If you have questions, you can leave a message at the comments.

5.00 M33 + 1.50 Kernel = Killing Machine, illustration by DL

Enough with the introduction. Read the guide after the jump.

Below are notes from Dark Alex himself.

because even deleting LFTV and korean font there was not enough space this time, this version will delete also flash0:/dic/apotp.dic

I’m unsure about what this file is for (maybe for japanese text predicition?) but system works fine with it.

IF you want to keep some of the things deleted by the 150k_installer do following things.

- Install DC7. Use the Format flash options in nand operations menu. Make flash1 size like around 1 MB smaller, make flash3 the smallest possible, and make flash2 a bit smaller (not too much, or you won’t be able to download games and demos from psstore). Then, make flash0 as big as possible and continue.

- Install 4.01 M33, update to 5.00 M33.

- Install 1.50 addon. Dump 5.00 using the latest psardumper, and flash the deleted files you want back.

Warning: You must do the following at your own risk. I won’t be held responsible for any damage it may do to your device.

The Requirements

• A Fat PSP (a.k.a. PSP-1000) installed with the latest custom firmware 5.00 M33.
• Enough battery so your PSP wouldn’t accidentally turn off in the middle of the flashing.
• USB Cable

The Guide

1. Connect your PSP to your computer and put it in USB mode.
2. Download the official 1.50 firmware and copy it to the root of your PSP’s memory stick. You can get the 1.50 firmware here.
3. Download the 1.50 Kernel Add-on for 5.00 M33 installer, extract it anywhere on your computer and copy it to /PSP/GAME5XX.
4. Go to your XMB and scroll to GAME>Memory Stick then run the 1.50 Kernel Add on update. Follow the onscreen instructions and wait. The PSP will restart automatically after the update has been installed.
5. Congratulations, you now have a full homebrew enabled PSP.

Again, thanks to Dark Alex for providing us homebrew goodness.

• Sleep Timer
• USB Auto-Connect

Don’t thank me for the guide, thank Dark Alex because without his hacking abilities, this wouldn’t even be here. And don’t forget to thank Sony for bringing us a cool handheld device.

UPDATE: For PSP-1000 a.k.a Fat PSP owners out there, 1.50 kernel add-on is already out. Read the installation guide here.

Below are notes about the custom firmware:

• Popsloader does not work (due to some changes on modules that sony did). UPDATE: There is a patch for this but it would require you to flash files which is dangerous if you don’t know what you are doing. Will write a post on this later.
• 1.50k addon not yet supported but will be soon

5.00 M33 Please

Instructions on how to install 5.0 M33 custom firmware will follow soon. Meanwhile, relax at the new colors of the site.

The other good thing is Dark Alex has started working on hacking the 5.00 firmware. So what will it be? A custom firmware with a new name? Let’s hope he does it in no time so we could enjoy the new firmware with the capability of running homebrew programs.

Thanks to darwin v. for sending out the good news.

Anyway, I’m real excited on what Sony is about to release next week. It’s the new firmware 5.0 for the PSP. Below are the new features added on the firmware.

PSP Firmware 5.00:

• Direct PSN access. PSN stands for PlayStation Network. If you don’t have a PSN account yet, create one now. This is like the App Store on the iPhone/iPod Touch, IMO.
• Sleep timer option. A feature that should have been there long ago.
• Full screen keyboard.
• Redesigned XMB background.

So how to do it? I’m not gonna rewrite the guide that I followed so I’m just gonna redirect you to it. But I’m here to give you some tips though, because some parts of the guide aren’t too clear. So let’s start.

You can follow the steps of this nice detailed guide. You must follow each step carefully. Here are some of the additional stuff that I did. They are numbered according to the guide/link I gave you.

On step number 9 from the guide titled 1st tab, Applications: The screenshot in this step is not updated. The latest WinPwn version has 3 checkboxes on the first tab, you must check them all, since you are on iPod Touch.

The rest of the steps are well clear enough for you guys to follow. If you are afraid that you might brick your iPod, don’t be. There have been no reports of bricked iPod yet.

To those having problems on how to get to DFU mode, here are the steps I did to have a successful DFU mode. You will need a speaker or headset for this one. And you must not be deaf.

1. Connect your iPod Touch to a USB cable.
2. Press and hold the home and power buttons until you hear the disconnect sound. When you hear the sound, release the power button and keep holding the home button.
3. Do not release the home button yet until you hear another sound. That’s the time you release the home button.
4. The screen on the iPod should be black. If you see a graphic on the iPod Touch telling you to connect to iTunes then you are on restore mode and not on DFU mode.

I hope the instructions are crystal clear for you guys. If you’ve got any questions or you need help, just leave your comment below.
