    1. Rename apktool.jar.rar to apktool.jar or remove the .rar, then copy apktool.jar and paste it to the apktool1.4.1 folder together with aapt.exe, apktool.bat, Command Prompt.bat, framework-if.bat, apktool.jar. then open apktool.bat. good luck!! :)

    3. Make sure you rename the apktool.jar.rar to apktool.jar and copy it, go to apktool1.4.1 folder where the aapt.exe, apktool.bat, Command Prompt.bat, framework-if.bat are there, then paste the apktool.jar.

      the tree must be

      apktool1.4.1/
      aapt.exe
      apktool.bat
      Command Prompt.bat
      framework-if.bat
      apktool.jar

      Delete
  5. done that I got them in the apktool1.4.1 folder apktool.jar.rar has been renamed to apktool.jar (still seen as rar file thought) should it be? but I am getting the 'java' is not recognized as an internal or external command, operable program or batch file, so whats the fix? read the comments and still have the problem!

    1. The Step 5 is the content of an apk after disassembled. you can edit it if you have knowledge about scripting like java or phyton. if you don't have knowledge about scripting, I only suggest to edit the photos.
