I wanted to give these phones to the kids with free freedompop 200MB data, and restrict the cellular data with AFWall to Hangouts for calls, Whatsapp (zero rated data free on freedompop) and the freedompop apps required by this SIM.
Here is the phone. You can get it cheaper than this, I got mine for 30 bucks each off eBay. They come GSM unlocked so the freedompop's UK SIM will work out of the box and allow you to roam in 30+ countries all around the world for free. HERE
The service is FREE and you can get the SIM card for 99 cents to 5 bucks depending on the promotions they are running, HERE
Next you will need a good link to Kingoroot, HERE
Install kingoroot, your ADB drivers and attach you Sky 4.0 to windows and make sure the drivers are properly installed.
Open Kingoroot and Press root, after some time you will see successful.
Now you should be rooted and have Kingoroot superuser and a few other apps installed. We need to get rid of the bloatware installed and swap out kingoroot superuser for SuperSU.
Next install SuperSU from the play store HERE
Open SuperSU and it will complain about the binary being out of date, you can try to update it, but odds are it will fail.
Next you need to install System App Remover HERE
Open it, find Kingoroot Superuser and delete it, then reboot the phone.
Once rebooted, open SuperSU and allow it to update your SU binary, then reboot.
First delete the kingo battery app
Now you should test SuperSU is working with any root checker from the play store.
If anyone is interested in my AFWall settings I can add them to this guide.
