hm plus the maintenance ramdisk seems strangely devoid of anything useful.
the other kernel, recovery, etc. dumps either look like "data" (e.g. mtd 8, 9, 10, 11, 12 - could be hashed or encoded?) or else "dos executable" (e.g. mtd 0, 1, 4 - weird but they actually only contain FF repeated and nothing else - possibly that means there's some hardware trigger that is required to read them properly? that or just they are in fact garbage)
