I had this "no images and texts" mode some days ago when playing around with the partitions on emmc.
It means the partition /dev/mmcblk0p2 (/home) is not accessible because of failed mount, changed filesystem, deleted files, etc..

I've read about this Hex-Editor approach first time today, and i don't know if it helps, but this was my way to a bigger /home partition.

- Boot into backupmenu and mount EMMC
- Connect to USB PC and repartition with a tool of your choice (me used gparted Ubuntu 11.11)
- reboot and flash combined image or restore backupmenu backup (worked both for me, after shrinking MyDocs /dev/mmcblk0p1 and growing /dev/mmcblk0p2 from 2 to 6 Gb)

Mainly followed parts of this How-to:
