'unknown USB device' - sofia bricked after flashing

Hi!

I was using DownloadGUI for a firmware download tool Flashtool_E2 on my 4good t700i (Sofia 3G, 4GB/512MB)

After the device rebooted once during firmware change it now looks like a brick: does not turn on, nothing happens during charge, when powered off and connected to a PC - 'unknown USB device' appears after ~10 seconds.

How to make it back alive?

Thanks

kudos to my colleague, was able to restore the device - battery was detached and the device was finally usb-recognized.
