How to Flash a Huawei 4G Modem (USB) for All SIM Cards

The realization that the time has come to flash a 4G modem for all SIM cards comes at the moment when the Internet tariff of your cellular operator, no matter which one - Megafon, MTS, Beeline or Tele2 - ceases to suit you. Then the fact is discovered that other SIM cards do not work with it. Today we will continue this topic - in this article I will show a universal way to flash a Huawei USB modem for all SIM cards of any cellular operator. It is suitable for most models sold in showrooms today, except ZTE, which requires separate instructions.

Existing firmware methods

Depending on which provider you used previously and whose modem you still have, you need to make a starting point when choosing a modem firmware method. For example, if before this you were a client of Beeline, then you can use special software running under Windows. In just a couple of minutes, you can reflash the device so that it receives signals not only from your own, but also from other operators. Due to the fact that the application can be found on the official website, Beeline is responsible for the safety of the work done.

There is also an option in which the user will not need to flash the phone again, because in order to give him access to other SIM cards, he will need to simply unlock the modem. But most often it is flashed with an already unlocked version of the software. So, now let’s figure out how to install new firmware on a Beeline modem that would be compatible with all operators.

What is modem firmware: why do subscribers need it?

Reflashing devices to access the Internet involves installing new software. If malfunctions occur in the software, then it is enough to reflash the equipment, replacing the software with new one. This process allows:

Increase the speed of the modem.
Adapt the device for different SIM cards.
Open access to additional functions.

Due to the fact that most 3G/4G modems support only one operator, this needs to be dealt with somehow. After all, you won’t be able to install a SIM card from MTS into a Beeline modem; it won’t work in this combination. The solution is either to buy a new modem, adapted for the current operator, or to reflash the old one. After completing this procedure, your USB modem will become universal.

How to reflash a Beeline modem for all operators

At the moment, the Beeline company uses the services of other manufacturers who provide them with their equipment, and Beeline employees sell modems with their software. The most popular modems at the moment are models from Huawei and ZTE. If you have a modem from the first manufacturer, then you can breathe a sigh of relief, because the process itself will not take much of your time, and you won’t have to understand much about anything. If you are the owner of a modem from the Chinese company ZTE, then you have to work a little before the device is ready to accept other people's SIM cards. In this article we will show the firmware options for both ZTE and Huawei devices.

A universal flashing method for most modem models

DC-unlocker client is easy to use and suitable for downloading and installing software. Its only drawback is that some of the functions are paid and require prior replenishment of the account linked to the program.

The program works according to the following algorithm:

installation and launch of the program;
resetting the modem to factory settings;
installing a new SIM card and opening the program (you need to click “Unlock”);
restarting the modem.

How to unlock modems from Huawei

We download an application that will independently select codes for certain models from Huawei. It is best to search for this application using the phrase “code calculator for Huawei”.
Download the application, unpack the archive and run the exe file. There is no need to install the program, since it works independently and without additional entries in the registry.
Notice the box highlighted in red with the text “IMEI”. This is the field for entering your model identification code. Enter your identification code and click Calc.
Finding the code from is quite simple, since it is located on the underside of the case. You can also find the code that you need to enter in the IMEI field that can be stuck on the box in which your device was packaged.
The remaining fields will be filled with information we do not need. You need to copy the numbers that appeared in v201 code to a separate text file or just to the clipboard. This is the combination that is needed for the modem to be ready to accept SIM cards from another manufacturer.
Next, we connect the modem with the new SIM card already inserted to the computer. Models from Huawei require a special code when the user tries to connect a “foreign” SIM card to their device, so we will need to enter the unlock code that you copied earlier into a special form. The form will appear immediately after connecting the modem.

This method is simple and convenient due to the fact that the user is not required to completely reflash the device. All you need is to unlock it using software, which can be found quite easily on the Internet. Now let's look at how to unlock or unlock a modem from ZTE.

Firmware for 4G USB modem for all SIM cards

First, for convenience, install the Russian language in it. After that, set it as , and either indicate the model number yourself or leave auto-detection.

Click the icon with a magnifying glass, after which the program will determine all the current data about the state of the modem firmware. We are interested in two points:

SIM blocking status - if it is blocked, then it is our client.
Code entry attempts - the remaining number of flashing attempts. Initially there are 10 of them, if there are fewer, it means someone has already tried to flash this modem.

If the device is blocked and there are still attempts to flash the firmware, then we return to the site and go to the “Buy Credits” section to pay for the program.

This will be both payment and registration - you need to select a payment method, enter your data and the number of credits to be purchased for the firmware. You can find out how many credits are needed for our operation by following the link “How much do I need?”

Since our model is already old, in this situation, to unlock it, you will need the “Generate Huawei modem unlock code by IMEI” item - at the time of writing, it costs 4 euros. For new models, we look at the option “Generate Huawei modem unlock code (AuthVer 3) by IMEI”, it is a little more expensive.

Select the desired item and return to the page to make a payment. Once the funds transfer is confirmed, you will be redirected to the next page. where the login and password will be indicated to connect to the site through the program. We return to the application and enter them in the “Server” section

You can also click on “Check login” to ensure that the entered data is correct and the balance of credits in your account is correct.

Next, open the “Unlock” tab, set the checkbox to automatic mode and click the “Run” button.

We wait for some time - and voila, an inscription about the successful firmware of the modem for SIM cards of all operators will appear in the program message window.

I will answer all questions in the comments!

How to unlock a modem from ZTE

Now Beeline produces only one device from ZTE as its models - this is a model called MF180. Despite the fact that it is quite difficult to reflash it, the minimum number of problems arise with this device. So, what do you need to unlock a branded Beeline modem made by ZTE?

Download the QPST package. In fact, this will be the main updated firmware file for your device. You can find it on the Internet, there will be no problems with it.
After this, you will need to download another important file that will unlock the modem from Beeline - PCUI.VN. Literally the first links that the search engine finds will lead you to the right decision. Download the “hacked” file and save it on your hard drive, it will be useful to us later.
We connect the modem to the USB port. When you first connect, a special application from Beeline will be installed on your PC, replacing which we can unlock the modem. However, now you just need to wait for the program to load.
The next step will be to check that all necessary virtual devices are loaded from our modem. To do this, go to Device Manager, and there we find the “Ports” tab. There should be different devices - ZTE Diagnostic Interface, NMEA Device and VoUSB Device.
We launch the QPST package that was downloaded earlier. Go to the Ports tab. There we click on the “Add New Port...” button and add a port from the ZTE Diagnostic Interface device. To find out the port number, you can return to the device manager: the name will indicate not only the name, but also the number.
Adding a port is easy: select the option that matches the number with the diagnostic interface from the device manager. We confirm.
Now launch the EFS Explorer application. It is through it that the user will be able to “penetrate” the modem software and change its contents. This software is installed together with the QPST package. When you first start it, a device selection window will open, but if you have a single modem connected, then you will just need to click “OK”.
In this file structure, you will need to find the PCUI.VN file, which will need to be replaced so that the modem can work with other SIM cards. To do this, simply change it to the one that was downloaded earlier, in step No. 2. Simply drag the file into the Explorer window.
After you have copied the PCUI.VN file, all that remains is to install new firmware from the provider whose services you want to use. The firmware can be found on both official and unofficial sources.

Possible difficulties

Problems often occur during the procedures described above. Therefore, I advise you to adhere to the following principles:

run programs as administrator. Absolutely all programs and utilities are very important;
follow the steps described correctly;
if something significantly diverges from the described process, then read about your model separately, consult on the forums;
if some step is done incorrectly, for example, you forgot to run the program in admin mode, and only if no processes are running, then you can restart the program and restart the device;
After everything worked out and you managed to change the modem to the smartphone, you should not use this smartphone in parallel with the modem, otherwise it will be blocked.

So, now you know different ways to flash a modem so that it is detected as a phone. I repeat once again that this process is not very simple from a technical point of view, and you must strictly follow the instructions, and if they differ for your model, then read about it separately on the forums.

Programs from the manufacturer

Huawei Modem is a universal tool that is great for a wide variety of modems, not just Huawei. The latest versions of this software work perfectly even with ZTE modems.

All that is needed for full operation is to enter the unlock code, which you can find out using the code calculator described above.

V201 is the right combination of numbers that does an excellent job of unlocking your device.

Problem

But there is one point that is worth considering in more detail. So you wanted to change the MTS operator for some reason. You look for a decent cellular service provider that can meet your needs, buy their SIM card, and that's it.

Nothing happens. After all, MTS does not want SIM cards from other operators to be used on their branded modems. And so they put a certain code so that you cannot use SIM cards other than the MTS operator. To unlock, you will have to spend a little time solving this issue yourself, or by asking your operator for help.

Beeline program

After uninstalling the software that is installed by default, you will need to install a more modern and convenient program, whose name is “Internet at Home”. What is her task? In just a couple of clicks you can change network settings, manually switching between one or another provider. The only catch is that not all SIM cards can be unlocked this way. “Internet at Home” from Beeline works great, but only with Megafon, MOTIV and MTS.

In order to “reflash” your modem, you just need to go to Settings, from there to “Network”, and then select the “Registration Mode” tab and set the value to “Manual search and registration”. There, in the drop-down list you can find the operator we need.

Using online services

To save time, you can use specialized online services that are capable of flashing no worse than the programs mentioned. To achieve the desired result, you should follow further instructions.

Calc.gmss.ru

This service is absolutely free and easy to use. The unlocking process will take a few minutes. What needs to be done: 1. Find the IMEI of your own modem. 2. Open a web resource. 3. Paste the found code into the appropriate field. 4. Click the “Generate” button.

Upon completion, the user will receive an 8-digit code to unlock the modem.

Speed-tester.info/

https://speed-tester.info/huawei_code_calculator.php

Another free resource where you can unlock your modem. However, the operation will take a little longer. The operating principle is similar to the previous method:

Open the site and find the time limit to enter.
Enter the appropriate combination in the “IMEI” field.
Wait until a suitable code is found.
Enter the element into the modem system.

Atyx.ru/huawei/

https://atyx.ru/huawei/

To implement this method, you will need more information, since in addition to IMEI you will need to enter the modem model. The action plan is as follows:

Open an online service.
In the “IMEI” line, indicate the identification code.
In the next field, enter the exact model of the device.
Click on the “Get code” button.

Beeline standard firmware update

To find the official firmware for your modem, you will need to visit the official Beeline website to find a page that lists the entire list of USB modem or router models. In the long list, you need to find your model and download the “Software Update File”. We connect our router. Next, unpack the archive, run the exe file and let the application update the software on its own, carefully following the instructions.

That's all the instructions on how to carry out the flashing process. As you can see from the instructions above, there is nothing complicated or dangerous about this, and the instructions that can be found in this article will help even inexperienced users who are worried about the safety of their own modem. Almost all modern software is automated, and the controls are clear and simple. All that is required from the user is, for the most part, to follow the instructions and select the correct firmware file.

Current update methods

In order to update the software, you must use a special program. You are allowed to use both the original program and its variations. One of the most accessible is the so-called Beeline. Its official name is “Internet at Home”.

You can download the program on the official page of the Beeline provider.

Please note that the original software largely depends on the model and manufacturer. That is why each manufacturer provides suitable software for download on its website.
