I wanted to try downgrading to 3.8 kernel to get more features working, but after the flashing of boot partition and rebooting it gave a kernel panic.
$this->bbcode_second_pass_code('', '
Kernel panic - not syncing: VFS: Unable to mount root fs on unknown block(8,2)
')
I created all the partitions using the method listed in here
