Straight to the point here we go. You will need:

• Android phone with at least 1.5ghz quad core (Qualcomm CPU no MediaTEK crap)
• 1GB of ram
• A ethernet connection of at least 50kb/s
• Google account
• Android 4.4.4 SDK api 21+

Let's begin >=')

Take your phone, unlock it and install Cyanogenmod on it or any other OS, or simply ROOT your device if it's not already. Search on XDA for a tutorial.

Download and install the following software:

Exposed framework modules:

http://repo.xposed.info/module/tw.fatminmin.xposed.minminguard

When all installed go to ru.gavrikov.hidemocklocations and check pokemon go apk.
In minminguard select PokemonGo Joystick and And Cheat Droid.

Open Cheat Droid and select "Mock Locations", Now you see Save.XML, press on it and add a value [int], Name it : "IFV", put "1" in value (without quotes). Save it and exit Cheat Droid, you can now try Mock Locations and it should be "paid" aka cracked. Now get rid of Cheat Droid.

Now open developer options
Stock Android: Settings > About phone > Build number

Once you’ve found the Build number section of the settings, tap on the section 7 times. After two taps, a small pop up notification should appear saying "you are now X steps away from being a developer" with a number that counts down with every additional tap.

Enable the development option "Allow mock location".

Now once all software is installed accordingly you should be able to open up PokemonGo Joystick without ads or Mock Locations(which is cracked now) and carry out the game play from within your lazy chair at home.

Have fun botting ;)
