If enabling the TTL option seems too daunting for you, I will help enable it over a TeamViewer (or similar) session. You will need to have the modem connected via USB, the drivers installed, and ideally have ADB installed. The device you're having me to connect to also should ideally be connected to the internet via a mechanism other than the modem. If it doesn't work out, I will refund you.
You do not need the ADB key in advance of requesting this.
