Quectel EM05-G not being unlocked

[Julian Andres Klode]

Despite support being in fcc-unlock.d

Bus 001 Device 003: ID 2c7c:030a Quectel Wireless Solutions Co., Ltd. Quectel EM05-G

the modem remains locked and enabling it fails:

jak@jak-t14-g3:~:master$ mmcli -m any -e
error: couldn't enable the modem: 'GDBus.Error:org.freedesktop.ModemManager1.Error.Core.Retry: Invalid transition'

Doing something like

# modprobe -r cdc_mbim
# modprobe cdc_mbim
# mbimcli --device-open-proxy --device="/dev/wwan0mbim0" --quectel-set-radio-state=on
# systemctl RestartModemManager
# mmcli -m any -e

makes it work.

Peculiar it seems that the mbim-proxy process that ModemManager started is hanging and causing the mbimcli command to time out (if I just run it manually).

Further investigation warranted, tips welcome.

Status changed to 'Confirmed' because the bug affects multiple users.

Works fine for me with Ubuntu 23.10.

Yes, correct, I no longer see the issue in mantic.
