Upgrade firmware for 3G USB modems of Indian ISPs

Is it possible to upgrade the firmware for 3G USB modems from Epivalley, ZTE and Huawei, without contacting the authorised service centre? I have visited the service center for one USB dongle, but they are refusing to upgrade the firmware, by giving excuses. Is there any other third party in India, who offers these firmware upgrades to the owners of these 3G USB modems as the backdoors are exploited by well connected people to spy on laptop users?
