Hi.

I have a mk3 nav i want to edit and install a new os in.

I downloaded the os found here:


If i burn the file as is using imgburn, everything is fine and there are no errors reported when verifying disk..

If i open the iso file with magiciso, extract the usw_load file and sw_rel.tbl, which are the ones i want to edit. I edit usw_load using navtweak 2,7 and sw_rel.tbl using free hex editor..

After the files are edited, i drag them over to the magiciso window which is still open, and replace the original files.

Then i choose save..

When i then try to burn the iso file, still using imgburn, i get loads of errors when i get to the verify files.. It says something like "comparison failed at lba something"....

After all the errors have been shown, the software claims that the operation was successful, but im not sure i want to trust it..

I discoverd also that if i open the original iso file with magiciso, and save it, without editing any files, i also get the errors during files verify....

Any thoughts.??
