I've a 32GB SD card, each time after i tried to change the partition size, it would not boot anyway.
As I posted in this blog: http://craigerrington.com/blog/installi ... hromebook/ you have to mark the partitions as clean after resizing to be able to boot:
20. The last step is to mark the kernel partitions as known to be god so that the firmware will attempt to use them when you boot up. This marks both partitions as successful, and gives the first partition a priority of 10 and the second a priority of 5. Technically both creating a label and marking as successful aren’t needed but it is good practice.
cgpt add -i 1 -S 1 -T 5 -P 10 -l KERN-A /dev/mmcblk1
cgpt add -i 2 -S 1 -T 5 -P 5 -l KERN-B /dev/mmcblk1

I'd really prefer not to disable write protection, or overwrite the stock BIOS. But also not sure how to get it working otherwise, as the process is pretty vague in that page.
