We previously discussed about what advantages and disadvantages of rooting were.
Rooting & Unrooting on A70 is very very easy compared to many other phones. It is done using the z4root app.
- Download Z4Root v1.3 from here.
- Install it using any other file manager.
- On your A70 goto settings>applications>development and enable usb debugging.
- Now start Z4Root and click on root.
Note: You can choose between complete root or soft root. A soft root is undone on reboot. A hard boot can be undone using the same app anytime.
You might want to install a custom bootanimation next.
Though the big step up in the evolution cycle will be to install ClockworkMod Recovery.
