[Kindle Fire HDX 7" & 8.9" General] galearned:
Good evening: I have an Apollo HDX that is an continuous gray and yellow splash screen when booted.

I have no idea what OS version it is running since it has been a long while setting in my junk pile.

I also do not know the history of the HDX since I acquired the unit second hand.

It sounds like there is some hope for recovery?

Can someone point me in the right direction for getting this unit resurrected?

On my LINUX workstation I do not see any logging when plugged in using a standard USB cable:

However, when a Kindle fire HD factory cable (2012 HD Fastboot cable) is used to connect to the HDX, I receive this logging:

Is the factory cable mentioned in this post the same factory cable used on the 2012 Kindle Fire HD?

I have worked on hundreds of the 2012 HD fires but, don't do anything with the HDX devices since they can't be bootloader unlocked. However, I would like to bring the HDX back to life it is possible. The tools for the HDX I see in this and other posts are for windows I presume and not LINUX?

Any help and direction would be helpful:::
