Comment 1 Tao Jin 2022-10-12 20:52:56 UTC
Description of problem:
A new firmware release of this modem through fwupd introduced a new fcc unlock sequence for this modem. Thus a version bump is required to support the device. See [1]. There is a F37 beta user experiencing the same issue. Compiled 1.18.10 with relevant libqmi make it work.

Version-Release number of selected component (if applicable):
Firmware used
https://fwupd.org/lvfs/devices/com.lenovo.t99w175.at.firmware

How reproducible:
Everytime.

Steps to Reproduce:
1. Insert a known working sim card
2. Boot the machine
3. install package, start systemd service


Actual results:
mmcli -m 0 shown modem not in working state

Expected results:
modem should work. A version bump of MM and libqmi is suggested.

Hi Tao J and others,
A work around for this is to install the offending packages from rawhide with the below commands (tested on fc36 but should also work on fc37). This will install libqmi-1.32.2-1.fc38, ModemManager-1.20.2-1.fc38, and a couple of dependencies.

sudo dnf install fedora-repos-rawhide
sudo dnf --enablerepo=rawhide update libqmi ModemManager

Thanks,
Nick.

Yes, in this way. It should work.

Thanks for the reminder. It seems that it was updated 7 days ago by the maintainer. Waiting it to be committed into update-testing fc37.
