The .bin does Not written to Device. The Tool find the Device, i choose the .bin ans click "load". It shows that it will make something with COM3 but nothing happens (the shown Log is shorter than in your Screenshot and ends after ... (COM3):

    So the ulocker does not work if only 1 device under COM-Devices is shown. Did i have to pay for the Unlocker?

    I have reinstalled the USB-Host on PC and used a second Windows 10 Machine, but nothing helps.

    Did anyone have an Idea?

    Many thanks

    Hey I've had the same issue using a telekom branded E557cs-321. My workaround was to use a Windows 7 computer instead of my windows 10 machine.

    Afterwards everything went fine as in #33 described. Just one minor addition:

    After flashing Huawei E5577s-321 Firmware version E5577s-321TCPU-V200R001B328D01SP0, I had to boot jump again and run the unlocker agin. Afterwards I was able to flash webui.

    If anyone else wonders how to connect to the hotspot afterwards (cause die SSID and so the WPA key changed) - you have to use the virtual cd rom provided when you connect the hotsport via usb.
