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 long we need to wait for a Huawei unlock code?

The approximate delivery time for a Huawei unlock code is 10 minutes to 8 hrs.

The average response time for a Huawei unlock code is 30 minutes (based on last 100 orders).
