Correct way to downgrade Pioneer A03 firmware!!!

[Antonio S.]

I succesfully downgrade the firmware of my Pioneer A03 using this method:

It is very simple:

1-Download Pioneer firmware 2.0
2-Remove installer (UPGDVD.exe) and place it in a folder with the firmware that you want to use to downgrade the firmware of your burner.
3-Make a shortcut of UPGDVD.exe to your desktop
4-Rightclick your new created shortcut. Go to properties and change the target from .../UPGDVD.exe to .../UPGDVD.exe /F
(carefully check the space after ".exe", and the letter "F" must be a capital letter).
5-Double click your shortcut. Wait until process is DONE!

I had some troubles since I upgrade the Pioneer A03 firmware to 2.0. Then when I tried to go back to firmware 1.9 it was impossible. Even using UPGDVD.exe or from a DOS bootable floppy disk. I lost about 4 hours trying to go back to 1.9. Then, making this simple steps, I succesfully download from firmware 2.0 to 1.90...

Well, Thank you.

I just tested it and it works great !
The /F works like a charm !
So simple ! I cannot believe. I wonder why pioneer did not tell about that. Grrrr.

AlexNoe, perhaps you can add thisinfo to your sticky Pioneer FAQ.

Thx again Antonio.

Please is there any chance of a copy of the firmware you used, both new and old as I can't seem toget anything to work :( Even the hardware hack.

Please!!! :)

TIA!
