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.

But, to unlock STC E5172s-920 Huawei WiFi router, neither Huawei modem code writer nor CardLock Unlock tool software will work.Huawei E5172s-920 WiFi router can not be unlocked with FMC unlocker software.
