I have K510. It was bought in England so there werent Baltic language. It had K510_R4EA031_MAIN_ORANGE_CO_RED50 and i fully flashed it to K510_R4EA031_FS_BALTIC_RED50 + K510_R4EA031_MAIN_GENERIC_CO_RED50. Now it says insert correct sim card. Is it possible to restore evertyhing back ? I have saved GDFS file.
