That makes sense (and I should have thought of it, aggh!) THe kernel is /mnt/initfs/linuxrc? So I need to have a copy of the 2007 kernel image available to 2008 and the 2008 image to 2007. Do they need to be in /mnt/initfs, or can they be elsewhere?
flasher-3.0 -u -F firmwareimagename.bin
Is there a kernel flasher for the tablet, or only one for the PC?
And which initfs? Presumably it does matter if it's a 2007 or 2008 one, where are they and how do I tell the difference?
