Today, I am sharing with you unlocking solution of Huawei EC315 Wingle Free via Firmware Update Process with the help of CDMA workshop tool. In this article, we mentioned three types of firmware. Out of three two firmware is in exe , which can be uploaded in Wingle simply by running the .exe file (Before running the firmware update, disconnect the internet and close the default software of modem). After a few minutes, your Huawei EC315 Wingle will be updated with new firmware.

In this article, one firmware is in APP extension. If you are unable to change the EC315 wingle with the .exe file then you can use app file. To run APP file, you need to download FWT Configuration tool V3.0 also.

  1. The FWT Software doesn’t open properly, It says “Failed to Serial Port.It was likely caused due to inadequate system resources or Collision with the software in Operation. Please Close other software using Serial interface, or modify the configuration”
    Now I don’t know what to do next.
    If I click OK on that window, the FWT window opens, but when I try Browse under Download Tool, it doesn’t find any AAP File and If I put APP in the search box,it says “Specified APP File is Illegal”
    What to do??? Please help.
