Hi! I have successfully update my S90-A, but no pop-up menu shows after dialing ####5993#. It only shows the internal version (i.e., S90A_S229_150428_ROW_Notset). Can you help me with this? And what is the purpose of the region code? Thanks in advance.

if ####5993# dont show anything try to using ####59930#
it for do factory reset and give country code to your device, it use for OTA update to recognize your device.

Go to recovery mode or system setting find the factory reset button and do factory reset so it will format all data and sd card on your device, backup sd card first
