Super! 

thank you very much for the new Firmware – worked like a charm-
the adapter is awesome UHD Deep Color at 60Hz – perfect. 
Really Great – i ve been waiting for this adapter long time.

small note: in the email i received (i also wrote this back in the email) it mentioned 

" most probably you need to set the Ultra HD Color to enabled manually in the setting of the TV for that HDMI2.0 port." -- in fact with this setting turned off the adapter does not need the update to work perfectly. Meaning you can use the adapter at 60Hz in a LG 4K if you do not turn on HDMI UHD Deep Color (i am yet to see the difference between deep color on and off), if however you want to use LG UHD Deep Color then the Firmware update is needed. 

Thank you again for great support and GREAT PRODUCT
