I have a Memorex Blu-Ray player which apparently can use the firmware from a Dune BD player (which has a hack that enables you to watch other regions in it). Unfortunately the online instructions are extremely vague for a newbie like me...here's what the online poster said:
Dune Prime/Cetre firmware and Memorex 2510/2511
cut header from dune firmware
0x000 - 0x0ff - it's header
and replace chksum
I have the firmware they're talking about. I also have HxD to edit the Hex files, have opened it and taken a look.
The first part -- cut the header -- I assume means cutting out the first 16 rows or such (from the top 00000 row down to the row that has an "F") which comprises the header of the firmware.
The second part -- "replace chksum" -- I have no idea on.
Any help would be appreciated, if theres more info I need to provide please let me know that too.
