Requirements

• A PSP with the 2.71 Firmware
• You have above 75% battery left
• Find out if you have a TA-082 motherboard, see this photo
• If you do not have a TA-082, follow the Generic Downgrader guide, otherwise make sure you follow the TA-082 downgrade guide

Instructions for TA-082 downgrade

1. Download the TA-082 Downgrader files.

2. Extract the archive and copy all files inside of "MS_ROOT" to your memory stick drive. If asked to overwrite any files, click yes.

3. Get the official 1.50 EBOOT, extract it, then rename the PBP file to UPDATE.PBP and copy it into the <pspdrive>:/PSP/GAME/UPDATE folder.

4. Navigate to the Photo directory on your PSP, select HEND folder. If successful you will see a blue then green screen flash, if not - try again.

5. Execute the 1.5 Enabler program on your PSP. When prompted to alter an idstorage key, press X.

6. The program will exit to the XMB. Now execute the generic downgrade, which will show in the PSP menu as "Update X.YZ".

7. When the downgrade is finished, you will be asked to press X to restart the PSP.

8. If all went fine, you’ll receive a blue screen telling you to press O. Do it, and re-enter your settings.

Instructions for Generic Downgrade (non-TA-082)

1. Download the Generic Downgrader files.

2. Copy the contents inside MS_ROOT to your memory stick drive.

3. Navigate to the Photo directory on your PSP, select the HEND folder. If successful you will see a blue screen flash, if not - try again.

4. Get the official 1.50 EBOOT, extract it, then rename the PBP file to UPDATE.PBP and copy it into the <pspdrive>:/PSP/GAME/UPDATE folder.

4. Run the Generic Downgrader

5. When the downgrade is finished, you will be asked to press X to restart the PSP.

6. If all went fine, you’ll receive a blue screen telling you to press O. Do it, and re-enter your settings.

Yeah, HEN is not active after a reboot.

ok, someone else had problems with HEN D so I recommend you try this. Download Hen C here: http://exophase.com/files/psp/hen_c.rar

start it up from the photo folder as normal, and now try starting the Generic downgrader.

i need help.

my psp turns off automatically when trying to run hend, not even showing a color screen.
my psp is TA-082 with 2.71 fw.
anyone can help me?

It's normal. The HEN startup is unstable, so you must try more times.

Normally it work's best for me if you restart the PSP without a disk inserted, and in the image wait for the icon to glow 3 times before hitting X to start the HEN.

Hi i have a psp with 2.71 and a TA-082.

While downgrading to 1.50 as explained above, when i ran idstoragechange, after reaching 100% and hitting X to restart my psp the screen just went black, and no matter what i do it wont budge, no matter what i press, and the power switch just wont manage to turn it off. I tried the screen brightness button just in case and its not that either... battery was at 100% and i didnt unplug it from the power at any moment... any ideas would be much appreciated

P.S. Ok i managed to turn it off without popping out the battery but when i turn it on i still just get a black screen with nada on it.. no logo, no purty sony sound... just a black screen that wont budge no matter what buttons i spam...
