Pictor On my Mac I ran 'sudo dd if=~/Downloads/ASIAIR_PRO_V1.4.img of=/dev/disk3' and waited 24<48hours for the dd to complete.
To make life easy, just use ApplePie Baker, but make sure you ask ApplePie Baker to back up as raw IMG (disk image file) and not compress it.
ZWO's images on the Google drive are compressed with RAR format; uncompress them (using Unarchiver, for example) first into a IMG file, and restore from the IMG file.
ApplePie Baker also defaults to compressing, so you will need to specifically pick "IMG," or you might end up with a useless file.
The error most people have with ApplePie Baker is the auto compression/uncompression nonsense (which depends on open sourced libraries).
If ApplePie Baker v2 really does not work, go to their download site and look for the 64-bit version of the v1 application. With v1, you will have to give permission each time you run ApplePie Baker for it to get "full disk access." I have been using ApplePie Baker v1 before ASIAIR, and still use it with my M1 Macs (a MaBookPro and a Mac Mini) with zero problem.
I retired from Apple (algorithms development, MacOS X graphics and imaging) in 2005, and still prefer to use applications than Terminal. I'd used Unix from back in the version 6 days, and then bsd, and have even fixed i-nodes manually on a Sun workstation, so I am no stranger to the Unix command line.
The full ASIAIR 32 GB IMG file takes about 25 minutes to burn using the same microSD card that ZWO uses, and with a decent USB 3.2 card reader/writer. It can take substantially longer with a poor reader, but should never take much more than 45 minutes.
However, I had to leave the ASIAir Pro hard wired to my home network to be able to configure the Wireless networks, otherwise the ASIAir Pro would try to switch to the network I was asking to connect to...
ASIAIR is not changing the network, iOS/iPadOS is the one doing it, because the signal from the ASIAIR v2 is abysmal.
Go to the WiFi settings in iPadOS. Find your home network, and tap on the little inscribed "i", then turn Auto-Join of the home network off. Otherwise iPadOS will switch to the better (home) network when it finds a marginal connection with an existing (ASIAIR) network. When connecting to the ASIAIR SSID, make sure you are never more than a meter from it. Even at a distance of one meter, there are nulls in the radiation pattern that you can lose connection with the ASIAIR's WiFi radio.
Now on to dealing with the weak Wifi signal but that's another problem.
The v2 ASIAIR needs to be directly Ethernet connected. Its WiFi antenna is completely shielded by metal. You can connect by LAN to a router (or a travel router, if you want a battery powered router), or even directly connected to an iPad.
If you want the ultimate in download speeds (especially if you have a ASI6200 camera) and you have an iPad that uses a Lightning connector, look for an Ethernet adapter than can take Gigabit Ethernet (most of them are only good to 100 Mbps). Most USB-C Ethernet adapters for the iPad are Gigabit. This is one of the few Gigabit Lightning adapter (I use it with an old iPad pro):

I use this with my two newer USB-C iPad Pros:

Once you have used direct Ethernet connected ASIAIR, you will find it hard to go back to the ASIAIR WiFi speeds.
I have a dedicated eero 6 mesh router node sitting right next to the ASIAIR and even with the eero's separate wireless backhaul, I only manage about 600 Mbps with the mesh. With direct Ethernet to a Mac, I think I have timed over 900 Mbps through the ASIAIR Samba server.
