Seeking help for Unlocking Huawei B310s-927 Router

[Veekay]

Only flashcode is good for this model, since it has v4 lock.
You need to download program dc-unlocker, install huawei datacard drivers, connect router by usb cable to computer and run the program dc-unlocker. Press magnifying glass button to detect modem.
If router will be found then type commands:
AT^SFM=1
AT^RESET
wait for device to reboot
then go back to program and type:
AT ^ NVWREX = 8268,0,12,1,0,0,0,2,0,0,0, A, 0,0,0
AT^SFM=0
AT^RESET

Thanks for your help.
Do I need to solder the USB on the PCB in order to connect the PC to the Router?
