Reference Picture of BOOT pin.
Connect USB Male to Male Cable to the Modem and to your Computer, It should show a COM PORT of HUAWEI Mobile Connect - 3G PC UI Interface.
Run commitblocks.cmd, and select option number 1.
Fastboot should respond to the Command Prompt with "OK" status, if it respond with a "FAIL" status. Repeat the steps.
After deleting nvram image of your modem, turn it off then repeat the first step above for jumping BOOT and GND pins.
Once you get to work the BOOT and GND pin again and it shows a HUAWEI Mobile Connect - 3G PC UI Interface COM PORT at Device Manager.
Run load_usbdloader.cmd. The script will automatically load usbdloader to the modem, once finished it will show a new COM PORT named HUAWEI Mobile Connect - 3G Application Interface on Device Manager.
Run B315s-22_Update_21.311.05.00.00_M_01.01_nvr.exe and click Start. When the Firmware Upgrader Program found the COM PORT of your device, device LED lights will lit up. Wait until the Firmware Upgrader completes downloading the software to your modem, and also wait for the modem to reboot itself.
Once you finish flashing the firmware to your modem, unplug the USB Male to Male cable then do a power cycle to your device (Unplug and replug the power adapter)
Plug LAN Cable to your modem and go to 192.168.8.1, if a Generic WEBUI of Huawei shows up. Congratulations, you've just successfully revived your modem from "death".
