Don't update Nighthawk X10 R9000 to Fireware V1.0.4.28 or you'll brick your router.

I did the FW update a few days after it was released, and while I have been following along this thread with folks that had the same issues or similiar issues I have found, posst upgrade, I have concerns, and wanted to share my horrifying experience with all.  First, I insured that I had a backup config of my router, which I did about a year ago when I got this router set up and configured.  I was on the .26 FW prior to this update of 10.0.4.28.  I ran the FW update and it seemed odd that it said it completed quicker than I am used to, I then received a message that my router wanted me to manually set it up, or use the setup wizard. Being alarmed by this, I quickly discovered one of my TVs streaming live TV at the time was DOA.  I quickly realized my router config was wiped out!  I was able to restore my saved config properly and get all WiFi networks working as expected.  Then, insured I turned off auto-update, which "was" turned off prior to this update.  While the router says I am on the latest FW now, (1.0.4.28), the QOS database did "not" update as shown in the release notes of the latest FW.  I also cannot manually, or automatically update it.  It simply does nothing.  After reading these posts, I have yielded from rebooting my router from the admin console, and HOPE, that "if" it requires a reboot or I lose power, this router does not wipe out its' config, or becomes a brick.  I am shocked that NetGear has NOT released a bulletin of known problems, or adequately updated this posting of threads.  I sure hope "when" they release the next FW update, that it works, takes away my concerns, and the QOS DB updates accordingly.  Incidentally, my 1-year warranty ran out less than a week after I performed the update.  Lovely.
