I tried again updating all my CL’s, this time with the new 220923 rom file, and I still can’t do it the way I used to. I’m getting the exact same result as mentioned above.
This is starting to scare me…

Anyone else has had that problem before?

Regards.

Yes, I have a similar issue, the update works but when I try to manually transfer a single ROM it fails. (both are running the same part of code)
It seems related to the Apple FTDI serial driver on macOS Monterey, I need to investigate further.
On the same machine, the update and single ROM file transfer works inside Windows running under Parallels VM using the same adapter, go figure.
It is on my todo list, sorry about that.
