The rooting method has been accidentally stumbled upon by an XDA developer senior member who repeatedly used the KingRoot universal one-click rooting tool out of frustration and it actually worked. We’ve heard similar stories from numerous people about using KingRoot a second or third time and it rooting the device, whereas the first time it failed. We don’t know exactly why that tends to happen, but if you want to give it a go on your Kindle Fire from 201, we think you will get the results you are hoping.
- The following guide is made to root the 4th generation of the Amazon Kindle Fire device running the current Android 5.1.1 Lollipop. We cannot be sure this root method works 100%, since it’s coming from a tip-off. But whatever you do, there is no harm in trying — you cannot brick your device with the KingRoot app.
BEFORE WE BEGIN
- You might want to unlock the Developer Options on your Amazon Kindle Fire device before trying to enable the USB Debugging Mode. You can do that by tapping on the Menu > Settings > About Device > Build Number.
- Now it’s time to enable your USB Debugging Mode on the Kindle Fire: Menu > Settings > Developer Options > USB Debugging Mode.
- Note that by choosing to root the Amazon Kindle Fire range of tablets, you are agreeing to void the warranty. You can always unroot the device and get the warranty working again, should you ever need to send it away for free repairs on the house.
HOW TO ROOT AMAZON KINDLE FIRE4TH GENERATION (2014) RUNNING ANDROID 5.1.1 LOLLIPOP
- Download the KingRoot 4.62 or above  directly to your Kindle Fire web browser and install the application.
- Open the KingRoot app from your Kindle Fire’s app drawer once it’s done.
- Tap on the large button that suggests it will root your Kindle Fire.
- Wait until the progress bar reaches 100% before you do advance to the next step. Anyone who does not get the KingRoot tool working the first time should exit the app and try again. Like we said, the original founder of this rooting method for the Kindle Fire says it didn’t work until he tried it several times.
- Once complete, you will get the ‘success!’ message coming from the app.
- Close your universal rooting application and then reboot your device from the Power menu.
In conclusion, that’s how to root the Amazon Kindle Fire 2014 using a universal rooting application called KingRoot. You should find the KingUser is available from your app drawer and it’s the app that is acting like your SuperSU. It’s essentially the Chinese version of SuperSU that does much of the same. It is possible to replace the KingUser for SuperSU on your Amazon devices if you ever want to install Chainfire’s gatekeeper instead. It isn’t necessary though, and KingUser has been around well before KingRoot and used as part as other popular one-click rooting method in the past.
