Re: custom firmware for PSP 2001 slim model?

Hi Delita,

When I turn it up, only the green light comes and stays for about 10 seconds, no display or sound. what can i do?

I guess your PSP is bricked. Have you done either of the following;
1.) Update PSP Firmware and interrupted it before it finished 2.) Installed a Custom Firmware (CFW) to play homebrew (games in Memory Stick)
If yes, it's certain that your PSP is bricked. There are easy ways to unbrick your PSP depending on your PSP version and MotherBoard. If you need help in unbricking your PSP, please give the following detail;
1.) Slim or Phat 2.) PSP Version (1000, 2000, 3000) 3.) MotherBoard (if available)
If you have known your MoBo to be a TA088v3, consider bringing it back to S0ny for MoBo replacement or have it replaced if you can buy one. Consider a new MoBo that is not a TA088v3 like TA085 or TA088v2 because these boards have recovery menu when installed with CFW.

I wish can download and playing games on my psp 3005. would u help what kind of game file, where to save it, or what should I do? please n thanks a lot.

Unfortunately, you can't. Downloading games onto a PSP requires custom firmware, which cannot be installed onto PSP-2000's with a TA088V3 motherboard, and cannot be installed to ALL 3000 series PSPs. The problem lies in the way the board is built, and if you attempt to install custom firmware, you will irreversibly "brick" it. If you don't believe me, check the rest of the internet, they will tell you the same thing. Also, you cannot install custom firmware if your current firmware is above version 5.03, unless you have a Pandora's battery, or a Datel battery tool. If you want to download games, then buy a psp-1000 series. i sold my slim and replaced the screen on my old 1000, and now i'm playing grand theft auto without a disk:) Otherwise, the only way to do that on a 3000 would be to buy it off of PSN, but i have never done that. Leave a comment if you get a 1000 and want to put custom firmware on it..

Well my psp at first had a version of 3.71(i could play iso games)... then i updated it to 6.00 (i can't play iso games) i want to make it 3.71 is that possible?....could you tell me step by...

Hi There!
Honestly, downgrading the firmware is tedious compared to upgrading it. I would suggest you have someone who has the technical knowledge to do this. Failed downgrade could lead to a bricked psp. Which will render it useless. Some can be reflashed and will work back while some cannot.
However, you can purchase a Pandora battery for you PSP. Remember: You CANNOT downgrade your PSP with any firmware higher than 3.50 without a Pandora's Battery.
You may check this link for a self-help guide in making your own Pandora battery. This is for a PSP slim model.!
Hope that helps!

My psp can't detect my memory stick 8gb

8GB is not support for PSP Phat (3.40oe-a) which it appears that you have. To be able to use a 8GB memorystick you must update your firmware to 3.90m33+ (click on firmware link, download to PSP)
8gb is now compatible in 3.90 even if your psp is Phat\Slim

I hope this helps and good luck

Reloading the firmware into a psp what won't start is called 'unbricking.'

I know that a pandoras battery will unbrick the phat psp-1001 model, but I have heard that it may not work to unbrick a slim. Since it's a paperweight now, it can't hurt to try, right?

You can create a service (pandora) battery and the 'magic' memory stick from any psp already running custom firmware. You can also buy them online, and if you look in the local classified ads website where you live, you can probably find people offering what they will call a downgrading service.

I cannot run through the steps here to create your own, but tutorials are all over the net and sites like youtube.

Will the psp slim battery will work for the psp phat.

Here is some advice for using the Slim-Style Pandora battery on the Phat PSP:

"Actually, I've messed with the slim Pandora in the Phat PSP's. You don't need to trim anything, just slide the head first into the battery slot and you will have to hold it in while its installing.

Also, if you are trying to use a slim Pandora battery, you will need to plug the Phat PSP into the AC adapter for it to work. The slim battery will not boot the Phat PSP on its own."

This advice is from this thread.

I have psp 3004 and

well ur asking a lot here. 3004 arent that easy. sony is making sure people like me.. or us and my friends cant use the handy software provided by coders and hackers[thank them] well from my expertise i was lucky in that the person who first modded my psp 1001 had to turn my psp phat battery into a pandoras battery. His slim psp was already modded with a method he claimed and showed me that he cut one corner of a chip in the battery case which let him run the update software to mod it.. so with his software on his slimn psp and a computer program that installs pandora files threw usb connection he made my battery into a pandoras which i still have.

So know i can use it to mod psps!!!!!! and i have software that can turn phat psp batterys into pandoras no problem. i just put that batterty in mine phat psp 1001 and run the program pandora installer providedby ppdv1.0 and usedbattery options and hit pandorize battery. i tryed using a slim battery on my phat and that damaged the battery and had to buy my friend a new one..

So what im trying to get to is if you can get a pandoras battery then i can help you,.

my friend has a Slim psp 2001 and i put the same modded software and the same process with my phat and it worked! so as long as you get a pandoras battery then you can run the software!!! this site showed me how to mod a psp with a pandoras batterty i already had. its worked on every psp i have installed the software[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[[warning WHEN INTSALLING MODDED SOFTWARE OR ANY UPDATE SOFTWARE FROM SONY YOU MUST HAVE YOUR PSP PLUGED IN AND A FULL BATTERY IF YOU DONT THE PSP MAY DIE AND MAY HAVE NO BRIAN{BRICKED} YOUVE BEEN WARNED}}}}}}}}}}}}}}}} but also just start the update program

ok so i did this 1. got "net framework version 2.0" and run it! find it by using google! 2. I then installed the psp pandora deluxe version 1.0 like stated in the website 2. find the Officail firmwares OFW 1.50 OFW and 4.01 OFW.. there are plenty of good sites just google each firmware.

then start psp pamdora deluxe and make sure ur psp is connected threw usb connection and make sure you know the drive name of the psp and select the it and then go to 1.50 and chose the eboot file and then 4.01 eboot file and then check them and then check 1.50 noonz downgrader and the despertar cemtrenio v6 [4.01 mm33 2] and then set dcv6 to the left button and the others as you plz and then check format memory stick and then hit other options and check add 4.01 m33 1.50 addon and then check suppot tolls for pandora and then support for xmb and the chose to run and hit yes and wait and now you have a magic stick which now needs a pandoras battery like mine to use

so you need to find out how to make a slim battery into a pandoras batterty without help from a phat battery. try looking up ways to make a pandoras batterty using a program that runs while ur psp is in usb connection and then the program asks for what drive your psp is and you selct it and then run it accordling .. sorry so much info
