Prerequrements

Assumed what you do it on linux machine and you advanced linux user.

You will need in your system:

• keytool - for generating new key
• jarsigner - for signing APK
• zip, unzip and zipinfo - for unpacking/repacking APK
• zipalign - optional, get it from Android SDK
• ffmpeg - for repacking sound (must be compiled with MP3 support)
• convert - tool from package ImageMagick
• optipng - convert and optimize PNG images

All this tools was in my system, so I used them. You can freely modify script to use other tools.

How to...

Step 1: Getting APK

Download APK via any service like apk-dl, evozi downloader or use apps like Raccoon.

You can also extract APK from your device:

    # adb shell pm list packages | grep someapp
    package:com.somecompany.someapp
    # adb shell pm path com.somecompany.someapp
    package:/data/app/com.somecompany.someapp-1.apk
    # adb pull /data/app/com.somecompany.someapp-1.apk
    3806 KB/s (5538818 bytes in 1.421s)

Step 2: repacking

Save shit.sh to EMPTY directory and then just type:

bash shit.sh your_apk_file.apk

Thats all!

WARNING: don't use it inside directory with other files!

Step 3: Backup your data

If in your APP have some sensive data (opened levels and top scores), you will lost all data during uninstall. So, PLEASE DO BACKUP now.

Step 4: Uninstall original app

    # adb uninstall com.somecompany.someapp
    Success

Step 5: Install repacked version

Result will be saved in shit_oldfague.apk, so install it

    # adb install shit_oldfague.apk
    4073 KB/s (5457196 bytes in 1.308s)
            pkg: /data/local/tmp/shit_oldfague.apk
    Success

And now enjoy new game!
