I have spent MANY hours on what to allow and what not to allow to provide you all the most reliable cross flashes while not locking you down needlessly.
IMO if you get a "wrong family" error and have to select bypass, you will brick your device. Its why I made clicking it not easy but everyone seems to want too!
The website matches this logic exactly, so if the website doesn't advertise a cross flash its because it can not yet be done.
Website says "21,838 crossflashes" as of right now, people always want more

We were at maybe what, 20 a month ago!?!
