I recently provided you with the download link of various network providers of different countries Huawei E3276 Hi-link modem and normal modem firmware. Today, I share a firmware update of the Huawei E3276 dongle, which can convert the Huawei E3276 Hi-link modem to the normal dongle. Huawei hi-link is different than a normal modem as it gets connected to the internet through a dial-up connection, but the hi-link data card gets connected to the internet using a web page.
Huawei hi-link modem firmware starts from 22 series, wherein Huawei normal dongle firmware starts with 21. Some users are happy with Huawei hi-link modems, and same time some users are not happy with the Hi-link modem, and some of the Huawei hi-link users want to convert their Hi-link modem to a normal modem.
To switch Huawei E303 and Huawei E3131 Hi-link modem to its normal state, go to the browser and type the following (make sure automatic connection to the internet is disabled):
http://192.168.1.1/html/switchProjectMode.html
Now your modem will be disconnected and switch to the serial port. Now a new device will have appeared in the device manager.
To enable GSM mode to execute the following command using DC Unlocker:
AT^U2DIAG=0
To switch back to Hi-Link, execute the following code:
AT^U2DIAG=119
Remove the modem and plug it again to take effect.
To issue AT command into DC-Unlocker software (Refer to this article).
You can use the same commands to switch Hi-Link Huawei E3276 to normal model mode. Might this command will work on Huawei E3276 hi-link modem also.
Additionally, I have found a firmware on ofmodemsandmen.com that download link is provided at the end of the article, converting Huawei E3276 hi-link modem to normal Huawei E3276 (I have not checked this firmware, it might damage your modem, do it at your own risk).
