GUIDE: Universal Unbricker V3 Using Official Firmware FAT/SLIM PSP.

But you have tried using the magic stick as a normal one and its ok? And whered you get the 8gb card and how much did that run you?

 

Yes, the memstick works fine in normal mode. My 1GB stick had 880MB left after installing all of the various update information. I bought the 8GB stick at Buy.com for $112.

 

does this only require one slim psp, a battery and a memory stick

 

Requires:
1x PSP Fat or Slime
1x 512 Or more memory stick.
1x Normal Battery
1x Pandora (Datel TOOL or make your own) Just spend the $32 and get the Datel TOOL it works great.

 

Thanks for the heads up. The Part2 link is fixed now.

 

i didnt understand good your add may be i am not so good in psp as well i just buy it from 1 week ago and as well i wan to downgrade my psp 3.71 mss-3 to 1.5 because knew i cant use any game or play any iso files in psp until i downgrade it yes ??? or i am wrong and what i suppose to exactly because your add is perfect but i think its so hard for me to understand it because i am not so good like u in the psp software and tools so i wil need more explain if u mind please

Thank you

 

I can't explain it any more clearer then what has been given. Plus it has images to follow. If your still confused on what to do then I would suggest getting someone that would understand it better or don't mod the PSP at all.

 

Hi guys,

I'm having a problem after following the tutorial. After everything is done installing and I try to start up my psp slim normally, I just see a black screen for about 5 seconds and my psp shuts off after. I've tried going through the tutorial more than once and the same thing always happens.

 

When you turn it on and get a black screen try pushing the display button if that doesn't work shut it off and hold the right trigger and turn it on see if it'll go into recovery mode, if it does just exit and you should hear the opening sound if still no picture hit the display button one more time. If none of this helps I would re-install the cfw.

 

Hey all, I just got my custom firmware installed, and I wanted to let you know what I did to get it working, just in case going through this guide verbatim isn't cutting it (as it didn't for me).

First off, the part that didn't work for me is similar to what others have stated, which is that it copies the files, but then goes straight to the credits. For those who don't know, this means it did NOT install the custom bootloader properly (in other words, your memstick will not boot and you'll be staring at a blank screen). No amount of swapping of battery or memory stick is going to fix this, if that's the problem you're having.

So now you're probably wondering how to fix it, right? Well, I can help you there, also. The good news is the download you got does contain most of what you need. The only problem you're having is getting the memory stick formatted properly, which will then allow it to accept the custom bootloader, which will install 3.71 M33, and then allow you to do the other upgrades. I could not find a solid consensus on how this should be done, but I'll tell you what I did. I should let you know now, I was using WinXP SP2, and no matter what method of formatting I tried, I could not get the bootloader to work. The only method of formatting that did work for me was using mspformat.exe, which I believe was designed specifically to format a memory stick properly to accept a modified bootloader. So, go ahead and find that program (Google is your friend!), as well as another program called msinst.exe (the bootloader installation executable), and we'll get started.

So here's what you do:

1) Format your memory stick using mspformat.exe
2) Extract all the files from uniunbr.rar to your memory stick, and also copy the ADD_ON contents to the memory stick - these are all the files you will need to install your custom firmware.
3) Copy msinst.exe and msipl.bin (located on the memory stick in the root directory) to an easy location (c:/ would work, for instance)
4) Up to this point, I'm assuming you have the PSP connected to the PC in USB mode, so go ahead and quit out of that mode, or unplug the USB cable.
5) Open a command window and get to the directory those two files are located and type: "msinst msipl.bin" (no quotes, just as I typed it, and don't get confused and think you need to put a drive letter in there, you don't!) and hit Enter
6) It will now wait for you to reconnect your PSP (Saying "Connect target MsProDuo" on the very last line), so go ahead and put it back into USB mode or reconnect the USB cable.
7) The expected text will be displayed (that was skipped on your installation before), so hit Y and the memory stick will be set up as a Pandora memory stick (meaning it will boot when you put a Pandora battery in).
8) Now you can follow the rest of the guide as stated, hitting X to install the custom firmware at the menu that shows up, etc.

Note: This method SHOULD work with any version of Windows, because of the use of the custom formatting tool, and because the custom installer is not used.

Hope that helps anyone else keep from going through the frustration I did trying to figure out what was going wrong.

Edit: Wording changes for clarity

 

After I put the Datel TOOL battery in and the menu comes up do I first install 3.71 ofw then 3.71 m33-2 or do i just install whatever one i want?

 

Ok, this is a universal unbricker you've created, so what it's allowing you to do is return to a "stable state" through an unconventional method. If you want to try custom firmware, do the M33, and then follow the rest of the guide to get you to the latest version (380 M33-5). The official firmware is included to "uncustomize" your PSP, should you so desire.

 

Oh ok good looks man

 

Ok when I dragged and dropped 150.PBP into my PSP Root folder no overwriting files came up, is that bad..? >_>

 

No only the PSP folder will be overwritten.

 

ok thanks man ^^ Its working now~

Edit- Hmm... It says that it can't extract Kernel Subset 3.40 or w/e.

 

You are probably running the despertar del cementerio which there is no need to run that.

Follow the guide as is. Does it say any where in the guide to run despertar del cementerio? Matter of fact it tells you to delete it becuase it is not needed.

 

Hi,

THANK YOU SO MUCH ^_^ your guide really Great & Easy.

I done downgrading my FW 3.80 to 3.71 M33-2 then I update to 3.80 M33

And then I update to 3.80 M33-4. My QUESTION: is ok I did not update to 3.80 M33-2 and M33-3? After 3.80 M33 ---> I update 3.80 M33-4 without update to M33-2 & 3.

One more Question ^_^ "How can I update to 3.80 M33-5?" Btw, do I need UMD to play ISO games with FW 3.80 M33-4?

THANK YOU SOOOO MUCH ^_^

my email: removed

 

Let's see... I think I heard that you can update via the internet now, with the custom updates, but I just downloaded it off of a website. If you Google the revision 3.80 M33-5, you'll find a site easily. As for using a UMD, I typically keep one in there, and did find that when I wasn't using one, it would error out. With one in, things have worked fine. I don't think a UMD is required for homebrew software, though, in most cases.
