The current firmware update for the Pioneer BDP-05FD is available from Pioneer: http://www.pioneerelectronics.com/PUSA/Home/Blu-ray-Disc-and-DVD/Elite-Blu-ray-Disc-Players/BDP-05FD
. Click on the Firmware tab then download the .zip file (titled firmware upgrade). Extract the contents of the file.
Burn the .ISO file that is inside the .zip file to a new CD-R (or CD-RW) using your burning software. (If you have Win7, you can use the included burning software to do this. Just right-click on the iso in the file explorer and choose Burn Disc Image.)
Then check that the disc has the needed files and that the files are the correct size: DLfile.pkg 95.3Mbyte (99,942,480byte), .DLdiscidentifier.txt 93byte, DLdiscidentifier.txt 93byte (for v1.71)
Then put the upgrade disc into the player (work with the controls on the front of the player instead of the remote). Then wait until the disc ejects (do not power the unit off or unplug it). Remove the disc and then turn the unit back on. You should see various information show up on the screen that will indicate that the upgrade is in progress. If it doesn't give the prompts, then you may have an unreadable CD. Try burning a new disc at a different write speed (lower); try using a different burner/computer if problems persist.
I hope this helps.
