As your device has already installed a DFL61_HARMATTAN_40.2012.21-3_PR_006
you cannot install anything that has a lower version number, and that includes also the country variant (as it would be seen as 'downgrade').
Probably best option is to stick with same version (which I think it's the Middle East generic version)

You cannot use 'Rest of World' version (version name ends with _001) and all operator specific which you probably want to avoid have a ending number >100.

I don't know what f/w version 059L4M9 uses, but if the flasher cannot proceed, it's because you tried a 'downgrade'. No risk to brick your phone, if you just follow the instructions.
