I have already covered the unlocking of Huawei E5377 and E5330 PTCL Pakistani 4G LTE MiFi hotspot router. But, with new devices, this trick does not work anymore. PTCL has put customized webUI and the device does not prompt for entering unlock code.

I tried to unlock it using Huawei HiLink (Mobile WiFi) tool since the Huawei HiLink (Mobile WiFi) software is created by Huawei itself for managing the devices through smartphones, but no luck with E5377u-872. Hilink Huawei modems are built of HiSilicon chip and it works on RNDIS technology, which does not require any drivers installation, and so it does not create COM port on PC when you connect it to PC with USB cable.

Now, problem is that, since it does not have any COM port, and all AT commands works with the only COM port. Means, you can not use any Huawei code writer / send tool.

But, finally, it could be unlocked using some freeware tools. I used Huawei HiSilicon Firmware WriterDC unlocker, and Huawei Hilink drivers.

How to Unlock Customized Huawei E5377u-872 PTCL Pakistani 4G MiFi Router ?

1. First download all three freeware’s, which are mentioned above (Huawei HiSilicon Firmware Writer, DC unlocker, and Huawei Hilink drivers).

2. Now, run Huawei HiSilicon Firmware Writer and detect the Huawei E5377u-872.

3. In this process, one COM port will be enabled and will be marked in yellow color. Now, download hilink drivers and update it.

COM port4. Now, detect the device under DC unlocker, which you have already downloaded.

DC unlocker - unlocking5. Detect the device under, DC unlocker. It will show the Application and Diagnostic port. Means, you have correctly done above all the procedures.

6. Issue the following command :

AT^CARDLOCK=”UNLOCK CODE”

Note : Replace UNLOCK CODE with your code corresponding to the IMEI.

If you get OK on the screen, then start dancing around the room. It is unlocked forever.

Above mentioned tricks can be used with all Huawei devices which do not have any COM ports and does not ask you for unlock code / NCK.

Unlock code is not free, you have to pay 6 USD. Interested then pay 6 USD in PayPal  and mention model with IMEI in the transaction.

A very big thanks to Ali Adnan Khan and Muhammad Nadeem Danish for testing and sharing the tips.

  3. Bhai, I am unable to get my PTCL E5377 unlocked. When I enter unlock code I am getting +CME ERROR: 50, may be because
    diagnostic port is not enabled by HiSilicon Firmware. Can you provide a
    solution for my unlocking problem, I am using Windows 7. I am getting following logs from Huawei HiSilicon Firmware Writer & DC Unlocker.

      • As you asked I tried it with UAC off, plus I also disabled Antivirus before trying it but I am still unable to unlock it.

        Also… There is Application port and a PC-UI port showing in device manager. The DC-Unlocker selects the PC-UI port as the application port so I tried using the application port mentioned in device manager as diagnostic port…. It gave the CM+50 or something like that error when Unlockcode was entered.
        Can you help me about how to sort out this issue as I cant unlock till the Diagnostic port is opened. Also please mention the exact format of entering the code.. is it with ” ” or without these??

    • As the details of DC unlocker log, your device has 0 attempts to enter the NCK. Means, it has customized firmware and without changing the firmware it is not possible. So better purchase DC unlocker credits and unlock. I don’t have EC5377u-872 modem firmware.

  16. DC Unlocker credit and unlock…it will flash it via dc unlocker….I think even DC Unlocker …payment via paypal…..I think ….any other method do you know for the payment please confirm.
