[Prerequisites]
  • A Rooted Chromecast (I recommend tvall's image..Here).
  • PuTTY or another Telnet Client
  • Android SDK
  • Active internet connection
  • Chromecast's IP Address

[How To]

Assuming you already have a rooted Chromecast and it is ON;

  1. Open your preferred Telnet client, I prefer PuTTY.

  2. Type in your Chromecast's IP Address and choose telnet as the connection type (I won't tell you how to get this, hint: check your router).

  3. Click open and you should now see a black terminal window.

  4. Type:
    Code:
    mount -o rw,remount /
    and press enter
  5. Then type:
    Code:
    setprop service.adb.tcp.port 5555
    and press enter

  6. Next type:
    Code:
    busybox vi default.prop
  7. Press the letter 'i' on the keyboard for 'insert'
  8. Use the arrow keys on your keyboard to navigate.

  9. Change:
    Code:
    ro.secure=1
    to
    Code:
    ro.secure=0
  10. Change:
    Code:
    ro.debuggable=0
    to
    Code:
    ro.debuggable=1
  11. Press the 'ESC' key on your keyboard so VI goes back to accepting commands
  12. Type ':wq' without the quotes and with the colon....Press enter.

  13. You should now be back at the / # prompt..
  14. Type
    Code:
    busybox wget http://goo.gl/TnbG99 -O adbd
    and press enter

    s45qSia.png

  15. Type
    Code:
    chmod 777 adbd
    and press enter

    9rKyPPk.png

  16. Type
    Code:
    ./adbd &

    It may not say anything and drop back to the prompt, this is normal

    vX6xTc7.png

  17. Type
    Code:
    ps | grep 'adbd'
    and press enter to make sure adbd is running

  18. Open a command prompt and cd to the SDK's platform-tools folder

    Your path will be different than mine.

  19. Type
    Code:
    adb devices
    and press enter

    It will probably not list any devices; this is normal. We just need to tell adb what device to connect to over wifi.

  20. Type
    Code:
    adb connect X.X.X.X
    where X.X.X.X is the IP Address of your Chromecast
  21. Press Enter

    Should say

    Code:
    Connected to X.X.X.X:5555
    where X.X.X.X is the IP of your chromecast.

  22. Type:
    Code:
    adb devices
    and press enter

    It should list your chromecast by its IP Address.

  23. Type:
    Code:
    adb shell
    and press enter
You should be greeted with a # prompt.

Congratulations! You now have ADB access to your chromecast.

Please note that this DOES NOT survive across reboots.

Just to clarify, this really doesn't do much yet.

As of right now you can't make persistent changes to the filesystem, because they revert after a reboot.

Heck you can't even remount the /system partition as RW at this point. Not sure why, but not too worried about it at the moment

/system is squashfs, a compressed readonly fs. Not difficult to modify, but requires reflashing the while partition (like gtvhackers image)

Awesome. I'm assuming it just unpacks the system after every reboot, I mean since the system seems to revert to not having any added items unless its in the image tahat was flashed?

You can't modify the filesystem without reflashing it. Squashfs is read only.
