the right job to do this filesize is bdm with ktag (for example) i did many of this ttrs-rs3 via bdm opening the ecu (not bench mode and not obd mode) and i newer had one problem as p0601.

if yes write it back, make diagnosis and delete all errors in each module and car must work without problem.

connect the ecu to ktag and read all files selecting maps as option to readout.
the flash readout must be 2,5 mb...after this you have the original intact file on which to make the mod and wrote back in the same way (bdm with ktag).

if you dont need mod file then you need only original obd file to restore via obd and car must work normally after diagnosis and delete eventually errors present.

anyway, post here your readout with ktag selecting the option maps because in this first readout you read each single component and not full (flash+mpc together)
