Hi just a noob question, I have bought an imported mazda 3 from Japan and came with an OS Ver. 59.00.448 JP M. I have been reading a lot on how to change the firmware to ADR version. Will it be safe just to directly convert it to 59.00.502A? or do I need to install the lower version of ADR OS first prior moving to version 59? Any tips will be greatly appreciated, specially if there would just be a tweak with how to change region without reinstalling the whole firmware. TIA.
