Installing extra files outside of Play Store

Extra binary files are necessary to deodex an Android Device. At this time, it is strictly prohibited for an Android app on Play Store to downlod binary files (.dex, .jar or APKs) outside of Play Store or to contain code capable of modifying other apps (which is what deodex'ing does). 


Please download this file and place it on your internal storage Downloads folder, /sdcard/Downloads or /sdcard/Download often works and retry deodex'ing your device.

Using 3C Toolbox 1.9.8.x or below, please use this file.


Here is the extract from Google Play Developer Program Policy, as updated on May 18th 2017:


The following are explicitly prohibited:

  • ...
  • Apps or SDKs that download executable code, such as dex files or native code, from a source other than Google Play.
