Furthermore, I would like to know if it is possible to unbrick/demo the device with the rootfs.img from let's say a hypothetical 3.2.1 image of a certain torrent.

Thanks in advance for the clarifications!
The adapter you linked to can be set to either 3.3v or 5v I/O.
Either setting should only be used with a level shifter setting.

Only a 1.8v serial adapter should be used without a level shifter.

The rootfs question: No.

When you read the tread(s) and directions for running version 3 firmware on a firmware version 2 device, you will find that what is actually used is a mixture of v-2 and v-3.
