I seem to have bricked my unit :/
I did the following:
Downloaded LAG3355_upgrade_v1.bin from the link.
Pressed upload onto the controller (the miners were running while i did this).
I waited untill the "everything is okay" screen came up.
I went up and removed power from the controller, waited ~5 sec, and turned power on again.
Thought the same. Did you upload the second bin file after that?
