Droidhen Defender Hack

Droidhen Defender is an free Android game.

Prerequisites:

• Root your device. Do not how to root your device? google + root
• Install a root file manager app: super manager (free) or root explorer (non-free)

The save file is in the following format:

<?xml version='1.0' encoding='utf-8' standalone='yes' ?>

   <map>
   <int name="magicStone" value="100000000" />
   <string name="magicStonecheckValue">4293191e6b63499927db54f204f7eb30</string>
   <int name="singleRetry" value="0" />
