FWIW, I tried to upgrade to the 1.06 firmware with the 1.02 app and it did not go well at all. Failed in fact. The Helix indicated that the update failed. Weh I rebooted the Helix, the welcome screen showed firmware 1.06 but then crashed; the Helix tried to reperform the update--which it could never complete. It was a brick.
I installed the 1.03 app and tried the upgrade again and it worked. Don't know if this is your issue, but I was in a panic for a short time...
