Requirements

• A PSP with the 2.80 Firmware
• You have above 75% battery left
• Find out if you have a TA-082 motherboard, see this photo

Instructions for downgrading from 2.80

1. Download the 2.80 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. Navigate to the Photo directory on your PSP, select the HEN_280 folder. If successful you will see a pale blue screen flash, if not - try again.

4. If you have a TA-082 PSP, execute the 1.5 Enabler program on your PSP. When prompted to alter an idstorage key, press X.

5. 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.

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. Congrats! When the process is completed, you'll have a 1.5 PSP.

did you copy over the downgrader files in MS_ROOT folder?

OK. So I copied all the files, then entered the HEN directory in the PHOTO's , the MS becomes very active and the PSP just turns off. Am I doing something wrong

no, 2.81 doesn't have a downgrader, you need to upgrade to 3.03 and use the 3.03 guide.
