Kindle Fire reboot loop problem – solved!

One day last week my Amazon Kindle Fire shut itself down because its battery was empty. I forgot about it for a few days but eventually I hooked it up to a USB charger and left it charging overnight. Next morning I found the Kindle Fire in a reboot loop. When connected to the USB charger, it would reboot itself every 5-10 seconds. When not connected to the USB charger it wouldn’t even turn on. It looked like the battery was so badly discharged that the Fire couldn’t even get to the point where it would start recharging the battery – even with the USB charger cable plugged in. I tried all suggestions I could find, including holding the power button for at least 20 seconds but the Fire still wouldn’t exit the reboot loop.

Sending it in for a replacement was no option since it displayed the yellow boot loader triangle for a few seconds while booting. A pretty obvious sign that this device had been rooted :-/

My plan B is to buy a so called factory cable on eBay in order to find out what’s going wrong with my Fire. Since it takes some time for the cable to arrive from Hongkong, I once again tried to get the Fire out of this cumbersome reboot loop. And guess what, this time it worked! Here’s what I did:

  1. Unplug the Kindle Fire from the USB charger cable
  2. Press and hold the power button (it should not turn on because the battery has run dry)
  3. While still holding the power button, plug the USB charger cable in (it should not turn on yet)
  4. Wait for at least 40 seconds while still holding the power button
  5. Once the kindle powers on, immediately let go of the power button and pray
In my case, the power light turned orange and the device started charging the battery. Problem solved! Most likely, this only works if the battery is completely discharged and not if there’s some other problem with the software on the device.
