I received my Helix today from GC. Attempted to run the firmware updater from a Windows 7 desktop and it failed during the update. I tried all the usual reboots, power down, reinstalls, etc. No dice. Screen was stuck on the latest firmware number but then indicates boot failure. I was sure it was bricked. Luckily I also have a Mac pre Yosemite. The update did succeed on the Mac first try and Helix app also seems fine. I feel lucky to have had an alternative install method.
