For those who stupidly Factory Reset the device and lost Root (like me) you will have to install and run Kingroot in adb first, then run these commands.
1. Skip through Google Setup and setup your Wifi connection.
2. Enable ADB in Developer Options
3. Install and run KingRoot apk from ADB
a. Download from
http://www.kingroot.net/wap/download; should be RushRoot-CafeUser-release-nolog-sdk-lc5F16405FCD186348-b220-svn373799-201609072045_signed_krsigned.apk
b. Move to your adb directory and rename to RushRoot.apk
c. Run these commands from command prompt
adb install -r RushRoot.apk
adb shell monkey -p com.cafeteam.installer 1
This should startup the KingRoot app and allow you to root your Kindle. Mine failed on the first try, so I rebooted and tried again with success.
You can now run these commands to disable the setup:
adb shell "su -c 'mount -o rw,remount /system'"
adb shell "su -c 'mv /system/priv-app/SetupWizard.apk /system/priv-app/SetupWizard.apk.old'"
adb shell "su -c 'mount -o ro,remount /system'"
