  1. in the E5172 updater tool, if we use “Force Update” option to forcefully load an unlocked FW on a similar device model of different number…e.g. push E5172As-22 on a E5172Bs-925 , will the update go through and ask for the firmware password to update it correctly?

      • From my past Huawei device FW updates, I knwo that whenever the FW updater tries to chnage the code, the inbuild autorization kicksin in the form of a FW update password ( based on IMEI number ). I think these devices use the newer algo v3 passwords , which I have for my Airtel E5172. I wanted to try pushing the Unlocked Megafone,RU code for E5172 to attemp a DC-Unlocker later on the Airtel router. By any chnace do you have the latest Airtel E5172 FW zip?

The package file send time got to as much as 25, but still nothing happens. Please how can I successfully get the universal firmware installed? Thanks in advance

    Can I flash E5172As-22 or E5172s-22 firmware in to E5172s-920 ? So I can use FDD 1800 network on E5172s-920.

  16. hi Kumar i have purchased the code and unlocked my Huawei E5172Bs-925 4G LTE CPE Router but when i put another sim card is showing no signal any help?

  17. Hi Kamalesh,

    I want to use this device as a wifi router for my broad band connection. What do i do??
    i have plugged in my broad band cable to the port in the router but only 1 device connects to internet while Other devices though are connected to wifi but are unable to access internet.

    • it is wifi router, not adsl
      You can’t connect a lan/broadband connection directly to it ,
      the lan port is for out connection only i.e. you can connect a lan cable from router to pc to get internet only.
      It shares connection of Sim network (airtel) only not broadband.
      To share broadband buy ADSL router
