If the code request window does not open, then:

Download the DC-Unlocker Client program, install it on your computer and launch it.
Click on the magnifying glass icon.
After the modem has been identified, enter the command AT^CARDLOCK = “Your unlock code” and press the Enter key.
If you receive an “OK” message in response, then the modem is unlocked.

Note

The number of attempts to enter the code is limited to 10 attempts. If the wrong code is entered 10 times, the modem blocks further attempts - the at^cardlock will not unblock it again, even if it is entered with the correct code. If you still managed to exhaust all input attempts, then it’s okay - they can be easily restored. This is done with the following commands: at^datalock=”unlock code” at^maxlcktms=10 10 is the new number of attempts (you can enter any number from 1 to 255). You can then enter the at^cardlock with the correct code and unlock the modem. This method may also work on other 4G modems from Huawei.

Don't rush to connect to the Internet right away. First, create an access point for your operator in the settings:

Modem firmware

The task of flashing the modem firmware is divided into 3 parts. Initially, you should download the transition firmware, which allows you to bypass the security mechanisms used by telecom operators to complicate unlocking or flashing the modem.

Before installing the transition firmware, you need to determine the current version of the firmware installed in the modem. To do this, you need to insert the modem into the USB port of your computer, launch dc-unlocker and click the round button with a magnifying glass in the window that opens. If everything is in order with the modem drivers, information about the modem should be displayed, including the firmware version in the Firmware line.

For older modems with firmware version 21.200 and lower or 22.200 and lower, you can use the universal transition firmware E3372h-607_Update_21.110.99.02.00

For newer ones, you need to select the transition firmware from those available in the archive in accordance with the last digits of the current firmware (161, 209, 391, 715, 778, 1441). For example, if the firmware version ends with 1441 (WIFIRE operator modem), transitional firmware E3372h-153_Update_21.329.05.00.00_M_01.10_for_.1441 is required

If the current firmware ends with 143 (MTS), the first stage can be skipped; transitional firmware is not required. If the final numbers do not match any of the seven options, you can try to download the universal firmware. If unsuccessful, another flashing method is required (for example, the needle method).

Next, you should download the modified firmware 22.323.01.00, which contains a number of useful features that allow you to unlock the modem and configure it to work with any SIM cards. The firmware is loaded using the executable file E3372h-153_Update_22.323.01.00.143_M_AT_05.10_nv

The modem's built-in web interface, through which you can control Internet connection parameters, is loaded separately from the Firmware using another executable file Update_WEBUI_17.100.13.01.03_HILINK_Mod1.11 This version of the web interface contains a number of additional functions for advanced control of the modem.

If the SIM card is not yet inserted into the modem, you need to remove it from the USB port, insert the card and plug the modem back in. It is better to use a card from an operator different from the brand under which the modem was released. This way you can immediately evaluate the success of the unlocking.

Firmware for Huawei E3372s

Complete set: firmware, interface and CDROM in one EXE file. Simplifies installation, simplifies recovery via needle. You can control TTL fixation for ipv4 and ipv6 with scripts that are suitable for other models, all drivers are included. Compatible with control scripts for E3372s. Works with almost all wifi routers out of the box. Efuse is missing, the online update is cut out, the local update via the web interface is saved. Works with virtually any SIM card. Tc speed cutter removed. Maximum stable interface.

What's new in the new firmware + Implemented an auto password for telnet, which is equal to IMSI when a SIM card is inserted. Without a SIM card, access to adb and telnet is carried out without a password. With the SIM card inserted, the login root and password are your unique password, which is impossible to forget. + there is no tc utility responsible for qos, restriction and prioritization of traffic from the modem, sysctl -p was added to startup because sysctl.conf did not work at startup, and it was necessary to manually activate it. + Added FIX TTL for IPV6 + Fix TTL v4 and v6 (After flashing, no shamanism with inclusion) + Entry is completely unlocked, all sections in RW + Removed from mlogserver startup. + Added FTP is started with the ftp start command - it listens only to the LAN interface, so penetration from outside is excluded. + Autorun has been optimized for better compatibility with entware, before this it was necessary to dance with a tambourine so that it would start correctly, tc_config (speed cutter) value was increased from 20.5 to 75, although I think it was worth setting it to 150 right away so that it wouldn’t cut at all when overheating, in general we’ll test it further Let's decide whether to raise it or not, as a rule, the speed often depends more on network limitations. To launch a web site for testing or debugging, use the command. Only HTML/JS/CSS/SH and without entware, otherwise the paths will need to be specified manually to the binaries. Also suitable for a personal page with a portfolio or homework for school. httpd -p 8000 -h /online/www If desired, you can place it on a flash drive httpd -p 8000 -h /sdcard/www Create the www folder in advance via FTP, for example.

Instead of 8000, you can use any unoccupied port. Port 80 is unfortunately occupied by the interface

To automate the launch, add these lines to the autorun. The site will become available at hi.link:8000 or via IP address wan and lan interface

E3372s_*.exe - for flashing using the standard method. E3372s_*.bin - for flashing firmware via the web interface.
