If You have QCN backup from the same devcie with working 3G/4G, You can try to write it into your device. Unfortunately, at the moment, we don't have QCN for this device model.

What option You have selected in "*#0808#" menu? And which COM ports or devices has been appeared in Windows Device Managers after this? Have You tried to reboot the device after selecting option?
