Add this to your Linux_for_Tegra/p3701.conf.common:

# update_local_cfgfile
update_local_cfgfile()
{
	# Update "num_sectors" in local cfgfile for the device
	# with FAB=501 and BOARDSKU=0004/0005
	local local_cfgfile="${1}"
	if [ "${board_FAB}" == "501" ] && [[ "${board_sku}" == "0004" || "${board_sku}" == "0005" ]]; then
		sed -i 's/num_sectors=\"124321792\"/num_sectors=\"124190720\"/' "${local_cfgfile}"
	fi
}

, and remember to call update_local_cfgfile() in flash.sh.
