Just hack the URL and you can go back in time:"Notice:
Users are advised to update the firmware version to v1.1.9, otherwise future firmware will not be able to install"
WTF!!!....So, if I can't upgrade from v1.1.8 to v1.1.9, say because I am out of town and DJi releases v1.1.10., I am stuck forever on v1.1.8?????
What kind of sinister 'hook' is DJi putting in v1.1.19?
