Hi! I need some help with upgrading firmware for RUT200. I have this one with RUT2M_R_00.07.01.3 firmware version. As I can see in wiki, it's first release for this model. When I try to upgrade to RUT2M_R_00.07.02.9 (Mass production) or RUT2M_R_00.07.03.2 (latest), modem cannot connect to mobile network. In status-network-mobile I can see IMEI, ICCID of sim-card and no any info about connection. In system-firmware-update firmware Internal modem firmware version version is "Ok" or "-".
