  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?

    Kudos to you for the good work you’re doing here. I have a Spectranet E5172s-970 CPE Router, I have actually attempted to unlock it using code, it shows that its been unlocked, but it only detects 3g.
    I already have a universal firmware downloaded for it and I I have tried using the above method to upgrade the firmware to a universal one, but ut’s like it is not going through. 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

  14. I have airtel India e5172bs – 925, it’s not sim locked…. But when i insert another sim, it doesn’t work, i guess that is because of webui of Airtel, is there any way to change the webui?? If i flash the universal firmware or firmware of e5172bs-22 , will it work or it’ll be bricked??

  15. Hello,

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

    Or is that frequency limitations are based on hardware ?

    Thanks in advance.

  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
