Really dont know how to do the "dmesg | paste" sorry.
You managed to type "dmesg" and hit enter. All you had to do was type "dmesg | paste" and hit enter.
Code
[ 1.543265] mmc1: Card stuck being busy! __mmc_poll_for_busy
[ 1.544665] mmc1: Failed to initialize a non-removable card
The eMMC storage fails to init ^ and thus isn't visible to the OS, so cannot be addressed. No idea what the underlying issue is, but normally the issue with Android boxes (not specifically WP2) is the chips go bad and throw errors. On the upside, it's failed but still allows SD card boot, which is better than starting to boot and not being able to continue (which can also happen).
