So lets say you want to root your phone.. well there is an app where if it can it will root it automatically. It’s called towelroot.
Now there is a few tricks you need to do.
First. You need to go to the towelroot website. You will need to click/tap the lambda image. This will cause you to download the free apk.
Second, before you run it. You need to find your modstring for your device from https://towelroot.com/modstrings.html.
Then run the app, click the v3 symbol to bring up the input box. Put the string in this by replacing it with the string from the aforementioned page. Then hit the lambda symbol 3 times and look to see what it says.. If you get “unsupported” then try it again. Otherwise you should get that the app was successful in rooting your device.
