1. Download super_disk.iso
2. Extract the file and you get an ISO file
3. Burn the ISO file to a CD-R
4. Put the CD-R into the player
5. The player will load and then reject the CD-R
6. Try play a DVD from another region

The above worked for my player with the BDP83-40-0925 firmware. This is for DVD only. I have not found a way to change Blu-ray.

11/24/09 My player has firmware BDP83-40-0925. I tried it and the player will not recognize the ISO file. It does not autoplay it goes to a root file menu and shows the file as empty. I burned two different disks and used a thumb drive with no effect.

11/28/2009 My player has firmware BDP83-40-0925, recognize the ISO file, reject the CD-RW and bingo!! Works perfectly. Thanks!

12/10/2009 Yeah, I have the same result as the poster above from 11/24/2009. I checked my firmware version (BDP83-40-0925) and I get the Home Menu screen. Oh, well.

12/25/2009 My BDP83SE has firmware BDP83-46-1210. Does anybody know if the steps above work with it? If not, is there any other file for this newer firmware?

12/12/2009 For posted in 11/24/2009 and 12/10/2009, you need build a CD with this ISO (Image File of CD), no a CD with ISO file as a file!!!. I have firmware version (BDP83-40-0925) and works perfectly. Tested with DVD of Region 1, 2 and 4, Region 0, Region all and MultiRegion excluding 1.

01/08/2010 I upgraded my BDP-83 with new firmware (BDP83-48-1224), the bad new is the cracked previous has gone, but I insert this CD with new firmware and Voila!! Works with DVD's of Region 1, 2 and 4, Region 0, Region all and MultiRegion excluding 1. As I know, the BDP-83SE only difering with previous BDP-83 in Audio board and Power board, the video board is the same, the new firmware is for both player, You can Try, I think is crack work for you.

01/25/2010 Yes! This works with the latest firmware (BDP83-48-1224)
