[Fire TV General] Skel40:
I made a list of packages that are safe to disable for as much performance and stability as possible for the version, 7.6.1.3/3701. Please let me know if 7.6.4.6 is working since I'm staying on 7.6.1.3/3701. I'm also running Wolf Launcher so com.amazon.tv.launcher and com.amazon.firehomestarter are disabled. Feel free to enable those if you would want the Amazon Launcher back up.

The thread for rooting 7.6.1.3/3701 can be found here: https://xdaforums.com/t/temp-root-b...e-gazelle-ps7613.4574609/page-4#post-88687053

The thread for rooting 7.6.4.6 can be found here: https://xdaforums.com/t/temp-root-firetv-3rd-gen-cube-gazelle-ps7646.4596733/page-2#post-88710101

Once you gain temp root come back to this guide and go to settings, my fire tv, developer options and enable adb debugging and make adb permissions and allow connections, adb devices. If you really want to really debloat this thing BE SURE to have a USB A to A adapter and ADB Debugging always enabled. It's better safe than sorry and having to unbrick the device with little to no recovery options!!!

From here these packages are completely safe to disable be careful which apps you disable outside of this list by preference because many applications can result in bricks, loss of remote pairings with the mobile app, casting (to not be confused with screencasting) , etc, etc which this list does disable those functionalities for faster performance. This list may be updated as time goes on when we know for sure what other apps are completely safe to disable without bricking, losing access to apps, not being able to login anymore, Prime crashing, and video crashing.

That's basically it for now. Let me know if there's other packages that are worth disabling. The ultimate goal with this guide is for stability, max performance without breaking the overall functionality of our device, apps, settings, and so on. It's still super weird how system apps work and how each of them does either make or break performance. A slow timely process for sure. I got another working Cube this time so operations are resuming. Keep this debloat list in reference and you're warned if a wrong package(s) does in fact bootloop the Cube forever.
