Hiya!

I pulled out my old Network Media Tank device, an Egreat EG-M34A and it seems to be bricked!

There used to be firmware around for the device (I have found one version) and also a couple of recovery files that would bring the box back from a failed firmware update.
All of the googled links are long dead - and the device is not supported.

I don't suppose that anyone might have the recovery files for this thing on an old hard drive?

Seems a shame to bin it!

CHEERS!
