Contacted the Tech Desk, jumped through all their hoops, and they replaced it with a NEW Kindle Fire HD 7, March 13, 2015. My second Kindle HD 7 has now failed, and after 5 phone calls over several weeks, and many many hoops to jump through, I’m told they won’t replace it, and I will have to purchase another.
