How to Unlock STC E5172 4G LTE CPE E5172s-920 Huawei WiFi Router?

Recently, I had written the article about unlocking of Saudi Arabia Zain E5172AS-22 WiFi router. Like other Huawei FMC routers, as I had mentioned in the unlocking of Huawei B683 (Orange Uganda), STC E5172s-920 (Saudi Telecom company) can not be unlocked. Other routers which come with USB port like E5331, E5332, E5776s, E5830, E583x, E585U-82, E585, E586, E587, E612/E618 and various other R series routers like R201, R210, etc can also be unlocked easily. But, to unlock STC E5172s-920 Huawei WiFi router, neither Huawei modem code writer nor CardLock Unlock tool software will work.
