[Fire TV Themes and Apps] petermg:
Enable ADB DEBUGGING on your Fire TV.

Find the IP address of your Fire TV.

Install adb on your windows machine.

Type

adb connect 192.168.1.115

(Just replace the IP I listed with your IP address)

then to confirm it connected type

adb devices

You should get an output like this:

192.168.1.115:5555 device

then do

adb shell

then run

pm list packages -3 -f

You will get an output that looks similar to mine:

Now copy and past that into notepad and go to Edit, then Replace... and under "Find what" put "package:", and under "replace with" put "adb pull " (make sure there is a space after the word 'pull')

Now click on Replace all, then you will have an output similar to this:

adb pull /data/app/com.zenstudios.ZenPinball.amazon-1.apk=com.zenstudios.ZenPinball.amazon
adb pull /data/app/org.chromium.youtube_apk-1.apk=org.chromium.youtube_apk

Now on each line just delete everything after apk, for exmaple:

adb pull /data/app/org.chromium.youtube_apk-1.apk=org.chromium.youtube_apk

becomes

adb pull /data/app/org.chromium.youtube_apk-1.apk

Now just save that file as a bat file and run it from whichever directory you want the files stored in on your PC and it will copy all your apks from your Fire TV (Stick) to your PC. It may take a few minutes.
