Unlock Huawei E3531 4G USB Broadband Modem

Recently, I have provided Download link of Nokia PC Suite V 7.1 and Zune PC app for Nokia Lumia and Download link of Samsung Kies latest version for Samsung Mobile (Windows & MAC OS). I have also shared the Download link of Telstra Australian Broadband Software and Firmware Free. I generally write an article about unlocking as you can find the Unlocking solution of Huawei E5373T Telstra Australian WiFi MiFi Router.


Today, I have come with an unlocking solution of Huawei E3531 Modem. In this article, we are not talking about the only unlocking procedure of Huawei E3531 dongle, but I am also providing the firmware download link of Huawei E3531 Modem for both hilink and normal modem. Don’t update or normal modem with hilink modem firmware and vice-versa, otherwise, your modem may be dead.

  1. Make sure that the computer has all the drivers. (The easiest way to make sure that your computer meets this requirement is to connect the modem to the computer and connect to the internet.)
  2. Close any type of connection programs like Mobile Partner or Branded mobile software (Modem must not be connected to the internet, modem light must be blinking, the software must not be running)
Administration of Modemfiles shall not be liable in case of an unknowing change of the firmware update of your modem. Additionally, if you want any specific firmware related to  Huawei & ZTE modem, dongle, data card & router, then leave a comment, if it will be available then it will be published. All the firmware files which are posted at Modemfiles, are free of cost and there is no need to pay anyone.
