Simple step-by-step firmware for the Tianjie CPE 903 router modem. After the firmware, the Russian language is available in the router menu. The signal in decibels is also displayed for more precise antenna tuning. The USSD function becomes available, allowing you to check the balance on your SIM card directly from the router's web interface. You can also fix the TTL in the router and change the IMEI. You can download the firmware from the 4pda website or purchase the improved web interface from me with easy installation!
