Unlocking the Beeline Huawei E3370 4G modem network

Huawei E3370 - old revision. Instructions for unlocking for all SIM cards.

Huawei E3370 of an old revision is very easy to identify and also easy to unlock: if the S/N of your modem does not begin with the characters “ G4P ”, then you have a device of an old revision.

Such a modem is blocked by an algorithm and is unlocked by entering the network unlock code (NCK). You can get such a code via the link https://www.plati.market/asp/pay.asp?idd=1819619 by simply entering the IMEI number of the modem in the form provided after payment. Entering the received code into the modem removes all restrictions on SIM cards from third-party operators and the modem becomes universal.

How do the firmware differ?

2 firmwares with code names Stick and HiLink have been developed for this modem. They differ in that the device will operate in different modes. When using the HiLink E3370(3372) firmware, it will be detected in the system as an Ethernet network card. In addition, this firmware is more stable and flexibly managed via a web interface. In the case of Stick, the modem is controlled by AT commands.

For H series

A special feature of the firmware for this series is the version number, which starts with 22 or 21. It is possible to replace HiLink with Stick. Management is available both through the web interface and through the application.

For Huawei E3370S modem

The difference between HiLink firmware for the S-series is the ability to display ID and network signal strength. The information will only be available after installing the web user interface.

Huawei E3370S can display the network signal strength.

For other series

You can install modified firmware on this modem. It allows you to eliminate problems with compatibility and data transfer speed. The modified firmware differs from the standard firmware in that it has a different digital signature and additional functions, such as a base station identifier.

Huawei E3370H - new revision. Instructions for unlocking for all SIM cards.

Devices of the new revision, on the contrary, have an S/N starting with the characters “ G4P ”. They are blocked by an algorithm, after which information about our device should appear in the log window, and the Hash 1 and Hash 2 fields should be filled with data:

Press the button “2. Calculate Encrypted Block" and wait for the data processing process to complete (depending on the power of your PC, its duration takes on average from 2 to 20 minutes). The result of the process completion is IMEI and Encrypted Block, in the log window:

Save the IMEI and Encrypted Block, we will need this information to receive the unlock code.

Go to the page - Unlock code for Huawei modems 2015. V4 Algo. The process of receiving the code takes 3-5 minutes at most, i.e. We select a payment method that is convenient for us, enter Encrypted Block in the appropriate field, click the “Buy Now” button and follow the instructions on the screen. Depending on the chosen payment method, you may see a “Return to seller” or “Return to store” button, do not forget to click it. After successfully placing your order, a registration form with the “Device Model” and “IMEI” fields will appear on your screen. We fill in the fields with the appropriate values, after which your unlock code will automatically appear in the “Paid for item” column.

If for some reason the form for filling out IMEI and Encrypted Block does not appear for you, go to the Oplata.info website using your e-mail specified during payment and select your purchase.

After we have received the unlock code, insert a SIM card from another operator into the Huawei E3370H, go to the web interface and enter the unlock code we received. In most cases, the unlock code request - “Enter NCK code” appears automatically (you can also enter it on the page https://192.168.8.1/html/simlockrequired.html):

After successfully entering the network unlock code, the modem will be unlocked and will begin to accept SIM cards from any operators. The screenshot below shows the modem's performance on the MTS RUS LTE network:

Inappropriate code: methods to solve the problem

If you cannot find a code suitable for unlocking, the only solution to the problem is to replace the firmware with a custom one. The software required for this procedure depends on the manufacturer. For gadgets based on the MTK chipset, you will need the SP Flash Tool or Droid Tools . If the locked smartphone runs on the Qualcomm platform, then you should use the QFIL .

Before performing a flashing that removes the blocking, you must, if possible, insert a Beeline SIM card into the device for which the smartphone or tablet is intended. This allows you to copy user-created files. After this, you will need to install any firmware, for example, AOSP or Lineage.

When the operation is completed, you should insert a card from another operator (not Beeline) and check the functionality of the mobile device. To flash and unlock Samsung smartphones you should use the Windows application Odin , and for Xiaomi - MiFlash . Another universal unlocking method is to change Android system files. The method also requires superuser rights and the presence of a SIM card from the operator for which the device is blocked.

Unlocking using the needle method

To remove the protection in this way, you need to remove the modem cover and find a special contact in the SIM card tray.

After this, insert the modem into the port. The service contact is not opened until the device is initialized.
