Modem test times out for me as well. I documented my issues and a workaround (atleast for modemmanager) in the thread at: https://forum.pine64.org/showthread.php?tid=9934I don't know what "screen" is, but I think it's the same for me.
I'm curious if you run `screen /dev/ttyS2` can you still issue AT commands? In my situation the USB connections on my BH died completely but the serial /dev/ttyS* devices are still operable. Dmesg prints some stuff on boot related to USB drivers I assume that isn't very pretty as well..
I think this is a hardware issue because it just happened randomly for me (and multiple images show the same issue). Very curious if this issue has been resolved on CE / 1.2 (I hope). Also by the way - my issues happened without any testing on crust / deep sleep; however what I will note is I did (and well... still do) have a habit of pulling the battery out of my pinephone to restart it - which maybe contributed..but then again most phones can handle this fine.. so this shouldn't break anything on the hardware-level from my perspective.
At least I see the /dev/ttyS* devices, and the dmesg USB errors.
Do you have the USB devices in /dev? Wonder if you might be able to post the output of `ls /dev/ttyS* /dev/ttyUSB*`; on a normal pinephone with a working modem I believe you should see entries for both serial & USB devices. On my Pinephone with the broken modem I only have serial devices.
