I have a dvd player that I use for my home use. I would like to change the background image in the firmware. I was successful in changing the image with the help of a software, but when I run the modified [url removed, login to view] on the DVD player, It displays a checksum error. I would like the candidate to locate the checksum alogarithm, and develop a simple application that I can use to fix the checksum error. The basic functionality of the application, will be to input a modified [url removed, login to view] and output the modified bank30rom with fixed checksum.
I have attached 2 versions of the original firmware, one is a 2009 version and the second is 2010 version. I hope this will assist in locating the checksum alogarithm.
Much more info regarding the model of the dvd player and software used to change the background image will be shared with candidates
