it explains HEND in the read me i think but not very clearly:


Start the 2.71_TA-082_-_1.50.exe. Install the Files to the PSP)

- Run HEN-D if you are not already running it.

to run HEND goto photo on your psp and run HEND from the memory stick.

i think it reboots then. after that execute the idstoragechange from the game/memory stick.

then it reboots again.

then you run the downgrader from game/memory stick.
make sure your psp has 75% charge or above.

you can put in a new one then format it and it will create the game folders and so on on the card

and to be safe when the battery is charged leave the charger in aswell when you are downgrading and upgrading

you dont run the installer to the psp/game folder mate.

run the installer and just select the path of your psp. mine is F:\

this will install the downgrader to all the correct folders.

formatt the memory stick mate and run the installer again and just choose the psp's correct path.
