Nexus 7 2013 - adb shell dmesg | grep mmc0

*This is what starting really making sense to me, the emmc card is recognized and everything works until the device tries to initialize it. That is what made me think that maybe it was wiped and is actually unallocated memory instead of being formatted. The error -110 is a timeout. It could also potentially not be wiped and still contain all the data but one of the bootloaders isn’t initializing it on startup.
