Huawei has launched B310, which is currently available through Airtel carrier in Africa and India. You can also get Huawei B310 in Indonesia by Bolt and in Saudi Arabia by STC carrier. STC branded B310s-927 comes with hardware version: WL1B310TM and firmware / software version: 21.316.01.00.1304.  Our team has personally tested unlocking of B310 Airtel, it is same for other countries routers too, if the device is asking for unlock code.

If Huawei B310 device is not asking for unlock code then you have to change the firmware, and also if you want can use generic WebUI.

The procedure is risky and any mistake make your device dead, so be careful while unlocking.

Arrange one USB 2.0 cable; if not then you can also use cut wire of mouse or keyboard. Dismantle the Huawei B310s-927 and soldier wires as shown in below image. Solder the cables of opposite side of USB 2.0 port to the motherboard of the device.

Note : Don’t make any mistake. Use the corresponding cable to solder with the board as shown in above image.

If you have successfully done above steps then you are now ready for proceeding with next step.

  5. Hi Everyone,

    So i got my hands on to the latest Airtel Locked B310s-927 Bought in the month of June 2016. See below
    Some confidential details hidden

    Found modem : B310s-927
    Model : Huawei B310
    Firmware : 21.311.03.00.284
    Compile date / time : Jul 18 2015 08:54:14
    Hardware ver. : WL1B310TM
    Dashboard version :
    Web UI version : WEBUI_17.
    SIM Lock status : Locked (Card Lock)
    Wrong codes entered : 0 (unlock attempts left : 10)

    I followed the exact same guide to unlock as mentioned here until step 7.

    After Step 7
    1, Generated the unlock code
    2, In DC Unlocker i ran the command as AT^CARDLOCK=”NCK LOCK CODE”
    3, Received the input as OK. Voila !!!! my Vodafone Sim started working in here.
    4, Now i get the problem that i was unable to change the APN so i needed a universal WEB UiI
    5, Downloaded the Universal Web UI from
    6, Right Clicked and Ran the “Update_WEBUI_17.” as administrator it asked for DATA LOCK Code
    7, Went back to DC Unlocker and ran the command as AT^NVRDEX=50502,0,128
    8, Received the HEX Code and generated the OEM / Data Lock Code
    9, Entered the DataLock Code there in WebUI Set and HURRAY !!!! You have an unlocked B310s-927 with universal latest web Ui

    Honestly, The point where i failed was to downgrade the Firmware (Although i did not need that still for testing reasons).

    USB Was soldered and plugged in > LAN CABLE Plugged> GODLOAD mode was on > hardcoded the ip in network settings > Multicast tool kept running for 30 mins.
    I seek detailed help of someone in downgrading / updating the firmware for B310 or B315.

    • I have the same router as you.. ..after unlock I updated WEBUI with your “Update_WEBUI_17.”, so I can edit apn. just that, no firmware update. Problem now is my username and password keep saying incorrect. I reset router with pin, typed “admin”, “admin”, same thing.. ..Please Help.

        • I thought so myself.. ..that’s why this is really frustrating. Please is there a lower version of the “Update_WEBUI_17.” file? so I can try using it. thanks.

    • I am gonna try your method today and i hope you haven’t faced any network problems till yet? I have the same router and firmware as yours that was bought in Aug’16. I am trying to unlock it for Jio.

    • Thanks Jango for the wonderful guide. Successfully unlocked it for JIO with your steps. However, the who unlocking took less than 10 mins wonder how you guys were stuck on multicast for 30 mins. I just used the USB Cable. No LAN Cables and NO GODLOAD Mode and NO Hardcoding of the IP.
