grab a new sdcard and make a sdcard install for emergency recovery use.
i use a modified danielt debian installer.
if it doesnt boot, then the emmc bootloader is probably toast. switch off the emmc and test again.
if that works, then boot the sdcard again and switch on the emmc quickly at boot (at light).
use the unbind+bind script to enable the emmc in userspace. see wiki or pbp-run-reset-emmc in pbp-tools
backup data from emmc and write a new install to emmc.
