Phantom II Will Not Start - Perpetual Blinking White Light

[jvoki]

I have the same, after updating me one Reactor still flashes white light.  The wireless module does not work.  After about 5 minutes, the Reactor will operate the optical and aux input.  Ethernet is also active, but the web interface is still waiting to boot.  Reset or any key combination does not work.  I contacted Devialet, a lot of bad advice, I sent a video, but I ended up not having the invoice they wanted for a guarantee.  Reactor was under warranty but I bought them second-hand without an invoice.  The second Reactor works great.  Now I work in stereo via a mono L + R cable from the iPod headphone output.
