Raw Kernel Commands
Get the internal kernel size:
xxd -ps -s 2092 -l 4 /dev/mtd3 | sed 's/\(..\)\(..\)\(..\)\(..\)/0x\4\3\2\1/'
Dump the internal kernel:
dd if=/dev/mtd3 of=vmlinuz-`uname -r` bs=1 skip=2048 count=$((`xxd -ps -s 2092 -l 4 /dev/mtd3ro | sed 's/\(..\)\(..\)\(..\)\(..\)/0x\4\3\2\1/'`))
Reflash a dumped kernel: dd if=vmlinuz-xxx of=/dev/mtd3 bs=2048 seek=1
