Well, the idea was to to get a foot in the door, not necessaerily to fix anything.
So, a while ago you had the regular boot getting to the boot animation. Since then this is no longer the case? Any idea what you did?
Unfortunately the toybox mount command is kind of screwed. It doesn't understand fstabs. So if you want to mount something you'll have to know all the details. Does "mount /system" in recovery work? Does this work:
Code:
# mount -t ext4 /dev/block/bootdevice/by-name/userdata /data
