There was a time when rooting Android devices was super easy. Phones like the OG Droid, Droid X, and other older Android devices could be rooted by universal root apps. Many of you may remember the Z4 root app. It would root any Android device on froyo and earlier builds of android. All you had to do was install the app and press the "root me" button. The device would begin applying the proper exploit, reboot your phone, and then you would just enjoy your rooted device.
Android is much more secure these days, and it is becoming increasingly harder to root devices. Some carriers simply will not allow it on their phones, and force OEMs to lock down devices bootloader tight making it even harder to root them. The Verizon Galaxy Note 4 for example has still not been rooted even though developers have been working on root for more than 6 months for the device.
A new app called "Root Master" claims to root nearly any Android device. They claim an 80%-90% success rate. The creators of the app scour the web for root methods, updating their app with all the latest root methods as often as possible. I decided to give this app a go today on my Nexus 6 running Android 5.1. Unfortunately the app was not able to root my Nexus 6. I have a feeling that it has not been updated to support 5.1. Then again the 80-90% could be an overstatement. Head to the link below to give it a try on your device and be sure to report your results in the comments below!
