How to Downgrade Your PSP from 2.71 to 1.5

Before you attempt to downgrade a PSP 2.71 (meaning PlayStation Portable 2.71 version) into a PSP 1.5 firmware version, techies on the net have cautioned PSP 2.71 owners about the dangers of downgrading. One risk is that you will wind up with a pretty useless PSP if something goes wrong. Now that's a pretty big risk to take. To prevent problems from developing, you should examine your PSP to see if it has a modern TA-082 motherboard first, because they say the downgrade doesn't work on these types of PSP motherboards.

To find out if you have a TA-082 motherboard, open the UMD and look at the upper right-hand side – if it gives this info "ic-1003", bingo, you have a TA-082 motherboard. Meaning, sorry, you cannot downgrade your PSP.

You should also know what the term "homebrew" means. Homebrew refers to video games which are created by members of the video game playing public, based on non-user programmable game platforms or stored on proprietary hardware. It may also cover video games which are marketed for commercial use but lack an official license from the console manufacturer for development. Homebrew video games are made by small teams or even an individual programmer, but are not necessarily illegal. Their production is made possible because the game platforms may be quite simple that even one person can create a homebrew program. A homebrew may also be known as a freeware software application.

The downgrade you use may be considered a form of homebrew actually. One source says the downgrade process from a 2.71 firmware into a 1.5 firmware goes like this:

Get the easy installer from http://www.sendspace.com/file/0mob1d via download.

Look for the archive where you should secure the files named:
2.71_TA-082_-_1.50.exe
README_DE
README_ENG_ORIGINAL_DARK_ALEX
TA-082_Downgrader.pngfile.

You may then format your memstick then change the PSP to its default settings.

Initiate the installer so that all that needs to be installed will go to your MS (inclusive of HEND)

At completion, you should check if you have a UMD inserted first (if you do, remove it) so you may move to the XMB area called PHOTO so HEND can be loaded. If it doesn't load during your first attempt, restart then make a second attempt.

Your PSP ought to restart on its own if the HEND has been loaded properly.

You may then visit GAME in your XMB to initiate load/start idstoragechange so that you can alter certain keys.

After the program is finished and your XMB is loaded again, you may return to GAME menu where you will spot the "Update X.YX" Generic downgrader. Proceed to load/start this downgrader.

The 1.5 firmware should proceed to be installed into your PSP. If it fails to do so, look for the command to press "x" so that you can restart your PSP. A BSOD should result. - - - Press "o", and punch in your data.

You now have a fully-functional PSP 1.5 firmware version. The same source on the net showed that some people with a PSP 2.5 may opt to upgrade first to a 2.71 before downgrading to a 1.5 version.

How to downgrade PSP 2.80 to 1.5

The steps in downgrading PSP 2.50 are easy to understand and to follow. All you have to remember is to strictly follow the procedures to have a successful downgrade.

There are certain requirements that you need to consider before starting. One is to check for the motherboard. If the unit has a TA-082 motherboard, then do not downgrade. This model does not accept downgrade. For those who have no problem with these requirements and are still eager to proceed then do the following steps:

You will need to install programs such as eLoader and xLoader. This is an auto-installation, meaning you will just insert the USB connector from your PSP to the computer and it will be automatically downloaded to your PSP. PatchSFO Tool, on the other hand, needs to be manually transferred to the GAME folder. These programs are needed to acquire another program, the Easy Downgrader.

Download Easy Downgrader from www.homebrewpsp.iphpbb.com to your desktop and extract the files. Open the Easy Downgrader folder and click the ‘2.80-1.50’. Send it to your PSP by clicking browse and search for the location of your PSP; click ok then install.

Disconnect the USB cable that connects the PSP to the computer. Make sure that the needed programs are already installed in the Photo section of your gadget. Hold start on eLoader and open PatchSFO Tool to patch the memory stick and the downgrader. After you have completely patched the program, restart the PSP.

Activate the xLoader to be able to use the downgrader from the PSP’s menu. Remember that the eLoader and xLoader are two different programs. Do not interchange them. Using eloader in this step can cause the bricking of your unit.

Restart your PSP by holding the power button for 5 to 10 seconds or until the unit turns off. Switch on again and this time, go to ‘Photo’ and look for the xLoader file and highlight it. Press the start button for a few seconds and wait until the screen turns white. If this happens, then you are doing the steps correctly but if the memory stick continues to blink and the screen does not show any error, try to reboot the gadget and retry.

The error means that the xLoader is already active. The next step is to go to “Game’ folder and look for the easy downgrader again and press X to remove it. Confirmation will come out and press O to start the unit.

Message stating ‘Downdate starting’ will appear on the screen and the memory stick will blink for a few minutes. After that a message stating that the procedure is already finished and that the unit should be restarted again will appear. Press the power button for the unit to restart and you will see an error window. Just press O and enter the settings.
You can now use the new firmware 1.50. Remember, the key to having a successful download is to make sure to follow the proper procedure. Skipping the procedure or wrong pushing of buttons might cause bricking in your PSP. You should also make sure that you fully charged your batteries or it has at least 70% life because it is also another factor that causes bricking of the system.

How to downgrade PSP 3.03 to 1.5

When downgrading PSP 3.03 to PSP 1.5, you will need the following items: your PSP 3.05, battery that is at least 70% full or a charger, Grand Theft Auto: Liberty City Stories, the unpatched version which contains the 2.0 update version. You will also need the 3.03 Downgrade files – Mirror and the 1.50 Update, the 3.03 update files are optional. This downgrade does not require any specific motherboard for the PSPs.

Check your firmware’s version. Make sure that it is 3.03; update it if necessary. You can check the version of your PSP by checking the system information that includes the MAC Address, System Software and Nickname.

In order to update your firmware version you should download 3.03 firmware from the website. Transfer this file by connecting your PSP, with the use of the USB cable, to the computer. This is an automatic download but make sure to put it in its proper folders. Go to PSP>GAME, then make another folder named UPDATE. Put the 3.03 EBOOT here, together with other files. Remove the USB and run UPDATE to get the 3.03 version.

1) Download these files (http://www.noobz.eu/joomla/index.php...tartdown&id=12 and
http://dl.qj.net/PSP-Firmware-1.50-F.../163/catid/163) and save them on the desktop. Extract these after. Ensure that you change the name of 1.5 EBOOT.PBP to UPDATE.PBP

2) Add the 1.5 EBOOT/UPDATE.PBP file to extracted files. It should be added in this folder: MS-ROOT>PSP>GAME>UPDATE. Remember that you will not over right the folder.

3) Transfer the data correctly from the Downgrader file to the memory stick of the PSP. Ensure that the correct folder goes with the right name.

Load the GTA:LCS copy. The PSP will then turn blank and then light blue and will restart itself. This action means that the download is successful. You can check the version of your present firmware by repeating the process in step 1 but this time, it will show that the firmware is already 3.03 HEN. You can now continue with the next step. But if this incidence did not occur, you might have missed some steps. Restart the tutorial until you get the desired result.

4) Run x.yz update. The screen should be in black with writings on it. This process will take up to 10 minutes. Make sure that your batteries are fully charged to avoid losing power. Any mistake on this step might cause bricking on your PSP.

After the process is completed, the PSP will require you to press X and the PSP will restart. If the PSP did not restart, press O again. Blue screen will again appear with notes that the setting was already corrupted. Press either X or O to confirm. It will again restart and after that, you can now have the PSP 1.5 version.

The procedure is very simple but do not do this if you are in doubt. You can always ask an expert to do it for you. This will not only help you succeed but you will also avoid the risk of bricking your PSP.

How to downgrade your PSP from 2.5 - 2.6 to 1.5

Before we go into details about downgrading, it may be necessary to define first what we mean by PSP. When we talk about the PSP, we are actually referring to the PlayStation Portable system which is believed to be the first handheld video game gadget to rely on the Universal Media Disc.


When we say PSP 2.5, PSP 2.6 and PSP 1.5, we are talking now about the versions of the firmware that the PSP you are using relies on. Firmware is simply a computer program geared especially for the hardware it is embedded within. But firmware goes a little bit further than ordinary software in that it is sort of like a cross between software and hardware. When you use a certain firmware version, most of the time it cannot be used without the hardware it was originally designed for. The firmware for a PSP is officially called PSP System Software by its original manufacturer Sony Computer Entertainment.

The PSP was originally designed by Sony Computer Entertainment employee Shin'ichi Ogasawara, on behalf of that company.

LET'S TALK ABOUT THE DOWNGRADE;

A source on the net says to downgrade your PSP 2.5 and PSP 2.6 to the PSP 1.5 firmware version, you need to find someone first who actually owns a PSP 1.5 firmware model. Without that person and his PSP 1.5, you will find it impossible to downgrade. Another basic requirement is that your PSP unit should not be a TA-082 model.

There are now two sets of procedures to be followed – one for the PSP 1.5 owner and the other by the PSP 2.5-2.6 owner.

The PSP 1.5 person must copy certain folders into the /PSP/GAME/ section of his memstick. The folders to be copied are named downhelper and downhelper %. He should then try to secure the 1.50 update from the website of the Internet source, and the update should be placed in the memstick (in the /PSP/GAME/UPDATE area actually.) Next step is to initiate the downhelper program, which will result in certain files and the flash to be dumped out of the updater eboot straight into the memstick. You will then find that the program should exit, permitting you to delete the updater out of /PSP/GAME/UPDATE. What follows afterwards is that a new folder dubbed "DOWNDATER" should appear in the memstick's root. The PSP 1.5 owner will then send the "DOWNDATER" folder to the PSP 2.5-2.6 owner so that the latter person can try out the downgrade.

If you have PSP 2.5, the instructions are as follows:

1) Look for the folder labeled DOWNGRADER/2.50/DOWNDATERTEST so you can copy it into the /PSP/GAME/ area of the memstick.

2) The PSP 1.5 owner should then transfer the DOWNDATER folder to you so you can copy it into your memstick root.

3) You may then initiate both the GTA and the eLoader.

Look for the downdater test within the eLoader menu. Be careful because once you initiate that, no message will appear – rather the downgrader process will automatically start.

The memstick ought to start flashing right after, to show that the PSP in your memstick is being flashed out.

Wait at least one minute after your memstick quits flashing, before pressing on the power button to restart the PSP.

If the whole process went smoothly, you will wind up with a PSP 1.5 version. But the risk here is that if it didn’t, your PSP winds up into a bricked version.

You may rely on the Wab Version Changer to alter your PSP into a PSP v1.50 should it indicate that you have a PSP v2.01 instead.

For a PSP 2.6 firmware version, all the steps followed by a PSP 2.5 are to be followed, except for step 1 where a PSP 2.6 owner has to copy the folder labeled DOWNGRADER/2.60/DOWNDATERTEST into the memstick's /PSP/GAME/.

If all goes well, then you will wind up with a PSP 1.5 regardless of whether you originally had a PSP 2.5 or a PSP 2.6.
