I’m ready to debloat (with universal-android-debloater), but before I do that Id like to backup the OS in the device to my computer.

If I want to backup with the stock ROM, Im redirected to a commercial service Im not going to use.

If I want to backup with twrp, it won’t let me backup via usb cable to the computer.

There must be a way to backup from the computer to the computer via usb, correct?

ETA: Can I backup with universal-android-debloater?
