Here is the debug mode of modemmanager.

$ sudo /usr/sbin/ModemManager --debug --test-low-power-suspend-resume --test-quick-suspend-resume modem.log

[nitinexclusively]

This issue was not reproduced in our environment . Already tested with OEM image as well .

[binli]

@nitinexclusively the X1 2-in-1 in my side still could not work with the same OEM image, could you share your firmware revision of the modem and BIOS? Could you share what's the possible reasons for FCC unlock failed? Thanks!

Hello Binli,

We've tested OEM image 1004 in Mersey with Em160R. EM160 FW used was EM160RGLAPR02A10M4G_01.211.01.211.

Please try by updating this via LVFS directly first.

Thanks!

[binli]

@Queztion yes, there is a new version, but it's failed to upgrade. It sounds that this is a bug of LVFS package of EM160RGLAPR02A10M4G_01.211.01.211, do you have any ideas how does it detach using modem_manager?

@binli I can see below in your logs:

primary port: wwan0at0

Primary port should be wwan0mbim0. Are you using OEM image ?

Just in case - >In order to debug , can you stop below SAR config service and reboot machine and see if you can see this issue or not ? https://github.com/lenovo/lenovo-wwan-unlock/blob/ubuntu-oem/lenovo-cfgservice.service Thanks

@Queztion Please update your BIOS version? Thank you!

[binli]

@Queztion @nitinexclusively I did update successfuly at the 3rd times. BIOS is 71W now. EC is 50W.

Devices that have been updated successfully:

• System Firmware (0.1.34 → 0.1.36) • EM160R GL (EM160RGLAPR02A10M4G_01.210.01.210 → EM160RGLAPR02A10M4G_01.211.01.211)

After upgrading the firmware, now the FCC unlock is success fromthe log, but the modem could not work, now it's the same issue with x1 Carbon, has the same log 'SIM inserted is of non-USA'

Hello @binli Thanks for update

has the same log 'SIM inserted is of non-USA'

This is OK and as expected . Can you please give below command and reboot machine: mmcli -m 0 --3gpp-set-initial-eps-bearer-settings=apn=xxxx,ip-type=IPV4V6,allowed-auth=chap,user=xxxx,password=xxxx

you can keep username and passowrd as empty but please give correct apn information

Thank you !

hi @nitinexclusively , I did reinstall the OEM image again, now I could connect it successfuly, it needs click the 'Connect' and then in a dialog window select 3gnet as 'Access Point'. So after upgrading the firmware, this issue is fixed.

EM160R GL (EM160RGLAPR02A10M4G_01.210.01.210 → EM160RGLAPR02A10M4G_01.211.01.211)

[binli]

Thanks all.
