Lenovo x230: split .rom for the 2 chips

[quanticracker]

wassup, was wondering how to split the final built 16M .rom into two 8MB and 4MB .rom for the two bios chips in the lenovo x230.
Currently using : dd if=heads-x230-maximized-....rom of=spi1.rom bs=1M count=8
dd if=heads-x230-maximized-....rom of=spi2.rom bs=1M skip=8 count=4
which is wrong, it bricks my shit everytime and i have to flash old image back.

thanks,

Sorry just saw this (discussions don't appear in matrix channel and are buried in my emails).

The rom is 12mb, and already split into top (4mb) and bottom (8mb) images per targets/xx30 recipe

I also saw you closed as resolved.
