Ya man 1.4 firmware update managed to brick 500GB shield TV consoles.
Nvidia advised users to rma their set.
I was lucky I was 25Mb away to complete the download and then my spidy sense told me to check the net for any info on the new 1.4 updates
and the sad thing is the 1.4 updates is still there for users to update ? wtf pull the damn thing off the net already
I was tempted to update it because my shield TV just simply refuse to see my PC and I cannot stream PC games. Very frustrated it worked before , uninstall / reinstall GE force experience did not help.
Crap last resort , will reset to factory and start all over again
