The source is released under the gpl, unlike the previous generic flasher.

Violation of gpl of this program won't be tolerated. Thanks.


Introduction
------------
This is an application to downgrade a ta-082 unit running 2.80 firmware and HEN-D
to 1.50, although teoretically can downgrade to any version, but only 1.50 has been tested.

The application, at the moment of writing this readme was tested in 5 psp's, with 5 success.
As always, this kind of application have risks, this one in concrete write to idstorage area
of nand.

The authors don't get responsabilized of any damage that may happen by the use of this
unlicensed software. You are on your own when doing it.

The method of ta-082 downgrade is based on research on hardware-downgraded ta-082 selled in ebay.
We realized that the process was not very complex, and easy to imitate by software.

READ CAREFULLY THE INSTRUCTIONS AND DON'T SKIP ANY STEP


Instructions
------------
- Copy the contents of MS_ROOT into the root folder of your memory stick.

- Get the official sony 1.50 update eboot and put it in the /PSP/GAME/UPDATE folder with the name of
UPDATE.PBP

- Run 2.80 HEN if you are not already running it.

- If running a ta-082 PSP execute the 2.80 idstorage changer. It needs 75% battery.
It will change some keys of your idstorage needed to downgrade the ta-082.

- The program will exit to the XMB. Now execute the generic downgrade, which will show in the xmb
as "Update X.YX" in the psp language.

- The generic downgrader will also need 75% battery. IT will downgrade your psp to 1.50.

- At the end, it will ask you to press X to restart the psp. Do it.

- If all went fine, you'll receive a blue screen telling you to press O. Do it, and reenter your settings.
  Welcome to 1.50.

- If things didn't go that fine, you'll have a non-functional psp, aka brick.
  You accepted that risk, remember.

Many thanks to the betatesters
