You'd only need to side step the map SD card authorisation if your map card was corrupted and you couldn't buy another one in your country. In the EU we just buy them off ebay saves the hassle of modding the firmware. The map workaround methods of shifting the overall.nds file defeats mapcare. Only if you wanted specific extras from the toolbox that its worth doing.
As for moving off your train I recall now that defects in the jumped to update were the reason why the poster was trying to get off that version but the defects might have been due to the Turkish firmware sold, so they had bought a mess why they were told to revert. Thus if the firmware works fine stay on it but if the reason to upgrade is that it's not working well, is that you have been sold a pig in a poke. An English expression.
