  1. good evening sir my router already the latest firmware 21.316.01.20.1304 but i did not check if its locked because its newly bought in store with my network is STC GO they said the sale boy do not remove the sim or else it will block the internet if in remove… any idea how can i know if its lock or not my device without removing the simcard…..

  2. Hi, my device already unlock and i forgot admin user name and password, because already change by me previously.

    If i reset this device, it will be lock again or not? And user name and password will be back to default (admin ; admin)?

    Please help me. Thx.

    • Once the device is unlocked, reset will not lock it again. So without any worry you can reset it and the user name and password will change back to admin

    • Without LAN Port the process is complicated and requires to open and solder the USB cable on the board. So, we don’t recommend that process as it is risky. If you still want to do that way on your risk, kindly pay 6 USD. We will send you the detailed instructions.

    • No tested on b310s-925. If you want you can test it on your own risk. For testing purposes the code is free. If you want to test, send us an email with the complete system information of your router.

    • You don’t need a PayPal account to pay.

      After entering the name and the rest of the details click ‘Place order’.
      You will be directed to paypal login page. There you will find an option to pay using credit card without creating an account.

      if the option is not there, click on create an account and you will get the option on the next page

  3. Hello , I did all the steps . But when I clicked the start button nothing happened.
    I unplugged the power cable and returned back but still nothing happened. Any suggestions?

    • Is it showing only one LED?
      If yes, all is OK, except you are not selecting the correct network card in the multicast tool. Select the correct network card in the multicast tool and click start.

  4. My router is unlocked already.

    I want to use the latest firmware of Huawei not any other operator firmware. I checked in your website only old firmware was available.

    On this link (link removed) i noticed same b310s-927 model with all features they are showing in that picture.. Pls scroll for all picture. There are may feature available on that firmware like USSD, SIM toolkit, LTE band selection, Voip, Ethernet, etc.

    Please tell the version of this firmware.

    Currently i am on this firmware 22 21.311.05.02.55.

    I can ready for any experiments with solder via USB.

    Waiting for positive response.

    • The link which you have shared is using customized firmware with the modified WebUI. You can look for it on the google. We are sorry, we don’t support it as the chances of getting the router dead are high.

  5. hi admin

  6. ok thanks a lot i unlocked my router with your good help and i inserted zain telecom is showing but the problem now my GO telecom sim is not working

    • Just speak to the Go telecom Customer Care and tell them the issue. It is related to the Network Provider. The GO company might be blocking the services in the unlocked router. Tell them that you want to use your SIM in a company unlocked router.

    IMEI : 866175025513352

    please send me the code asap.

    • The uploading via multicast tool might not take more than 10 minutes. You will have to tell the exact situation of the router which is there at present. How many led are ON?
      I am assuming that only power LED is ON, in that case you might be doing either one of the following mistakes.
      1 – You might have not selected the correct LAN adapter from the List in the Network card list box of multicast upgrade tool.
      2- You might have not restarted the router after clicking the start button of Multicast upgrade tool.

      Kindly provide the complete information so that we can suggest you the most appropriate solution.

  12. This was the issue:
    “You might have not restarted the router after clicking the start button of Multicast upgrade tool”
    I repeated the process again and it’s unlocked now and working properly.
    Thanks for your help.

  13. Dear Admin
