Glo unable to do a facotry reset after disk image copy

What I did to brick my Glo.
Copied across a earlier firmware as per instructions.
Didn't delete upgrade file in root.
Switched Glo on, get to the wifi screen, enter router code, "success" but a few seconds later it says "connection error".
Restart, same thing.
Factory reset it hangs at the same place.

Connected Glo to pc for desktop activation, when I clicked on Kobo desktop for activation it also gave "network error" and froze windows, I had to do a forced pc shutdown.

Removed SD card and re-imaged it, It hangs at exactly the same place.
Factory reset with new image, hangs at the same place.
Disconnect battery and reconnect, same problem.

I have successfully imaged the card twice previously with no issues.

If I connect the Glo to my pc (not Kobo desktop) the Glo appears as a drive and I can see the files on the Glo. Would it help if I placed the "upgrade" folder and a firmware in the Glo's directory to force it to upgrade ?.

any ideas ?. before I bin the thing.

I read in another post that its possible to bypass the registration process, is this still possible with the Glo ?.
