Hmm, it would seem my post including the link wasn’t approved by the mods, so I won’t include the link to the firmware.
CarPlay2Air support got back to me last night. Their suggestion was to flash a firmware from 6-17 (with a Google Drive download link) via USB, and then try to repeat the OTA update afterward. However, since I can’t get any response of any kind from the device and never got a chance to use a USB stick for flashing to make sure it works, I have no idea if that process is not working because the device is bricked or because my USB stick isn’t a good fit. (I don’t have anything smaller than 16 GB, so that might be a problem.)
No idea if I should be putting any stock in anything their support says, but maybe it will work for someone with a USB stick they’ve successfully used in the past?
