I flashed my phone with a different region firmware since the latest one was not available for my region. Formerly it was "M_EST_N_AFR" which i flashed with "GENERIC_S_ASIA_LEVAN" so far it hasnt given me any problems. Recocnizes the operator fine which is expected in todays world of widespread GSM roaming. However under service menu, it still tells the region as "M_EST_N_AFR" dunno why but im not bothered as long I have the desired fw and phone works fine. You may also try at your OWN risk to flash with a different region fw if latest one is not available for your region.
