How to Unlock Huawei E8372h Locked to Mascom Botswana?

  1. First, install the WinRAR in your PC.

2. Unzip all the other files.

3. Install Huawei Mobile Partner in PC.

4. Dismantle / unscrew the E8372H.

5. With a small wire, touch the ground and boot PIN, as shown in the below image.

6. In the same condition, connect the device to PC.

Note: If your PC / laptop has Sound-card, then you will hear some sound. Same time you will see some drivers are getting installed in your PC. Means, you have successfully shot the boot pin of the device.

7. Run the balong tool which you have already downloaded.

8. Click on Detect button, it will automatically select the BOOT COM port.

9. Under Loader select the usbloader.bin file.

10. Now click “Load” button.

After a few second you will hear another sound and some drivers will be again installed in your PC.

8. Click on Search button of DC unlocker.

Note: Check the IMEI in the result of DC unlocker log. If it is showing 00000000 in front of IMEI text, then stop it. It needs to be fixed, which I will do remotely. Unlock code of Huawei E8372h is not free, you need to pay 6 USD through PayPal button of this website. While paying plz mention model with IMEI in the transaction or can also email with details. It will be fixed within 8 hrs.

  1. Hi,

    I am following this guide on my Huaweii e8372h-153 locked to O2 UK and running firmware version 21.210.07.01.405.

    Everything runs fine up to step 11, however step 11 returns “Download Failed – Error 19”.

    Do you have any idea why?

  2. I have followed the above steps and managed to install 21.110.99.03.00 on my E8372h successfully. I then opened DC Unlocker and noticed my IMEI and Serial were zeroed out and my device now said unlocked. So I corrected the IMEI and Serial using AT commands and set my Datalock code to 12345678.

    Then I updated my wingle to 21.210.09.00.00 and also installed the WEBUI_17.100.12.00.03_RE5. My device updated successfully and still shows unlocked in DC Unlocker. If I insert an O2 sim the device works perfectly, but when inserting another network I just get no service. It appears as though the device is not actually unlocked although DC Unlocker says it is…

    Please can you help me?

  3. It seems that after doing the boot pin short and downgrading the firmware, my nv hash is zeroed out along with the IMEI and Serial number. How can I repair the nv hash?

  4. I have fixed the serial number and IMEI. They are correct. I am wondering about the NV Hash, it is showing all zeroes:

    AT^NVRDEX=50503,0,128

    ^NVRDEX: 50503,0,128,00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
