fixed it; had to use a WINDOWS tool provided by comebuy: Open_C_upgrade_Tool worked like a charm.

Linux section did not work for me; (https://developer.mozilla.org/en-US/docs/Mozilla/Firefox_OS/Phone_guide/ZTE_OPEN_C#I_bricked_my_phone)

BUT: The software update provided over the air, that is available immediately is NOT working!!!! Broke it instantly again; had to repeat the windows upgrade
