I am pretty sure we have not solved the matter of file transfer, when Desktop Operating Systems are not involved, so especially portable device to Onyx device.

With Desktop Operating Systems we are fully set, as expected:
-- USB cable plus MTP protocol;
-- USB connection and ADB command set (`adb push`, `adb pull`);
-- other methods, probably more convoluted.

Mass storage device to Onyx device, it seems patched but not something one generally recommends as practical while on-the-go:
-- special cables and external power sources are required (I have at this moment no time to check the posts).

Mobile device (e.g. Android) to Onyx device, I am not sure it was done:
-- the most straightforward and promising way looks one via a Bluetooth connection, but I have not yet managed to try.

Has anyone tried wireless file transfer between e.g. one's phone and a Max2 or Note?
