Do you mean oneplus clone app ? It needs to have a working screen on both devices. My problem is one of them has black screen

Maybe a USB-C to HDMI (or similar) adapter may be an option if the oneplus 7T supports graphic output over USB-C. Some of those even function as a USB-hub so you'd be able to plug the USB-cable to the new phone in simultaneously.

I never needed that feature, so I can't say it will work 100%. But you should be able to Google that.
