EM7455 Thinkpad T470 Debian Bookworm 12 Troubles

roburn · November 1, 2023, 2:56pm

Hello I am new here and don›t know where this questions belongs, I have a Refuhrbished Thinkpad T470 mit 4G LTE-A Qualcomm Snapdragon X7 LTE-A Sierra Wireless EM7455.

lsb_release -a; uname -a; lsusb

No LSB modules are available.
Distributor ID: Debian

I downloaded the files:
SierraLinuxQMIdriversS2.42N2.64.tar.bz2
GCF & PTCRB Approved—Release 27 (current unused)
GCF Approved—Release 29 (current unused)
modemmanager_1.20.4-1_amd64.deb

I installed pppconfig

Then I tried:
Root Shell
sudo mkdir -p /usr/src/SierraLinuxQMIdrivers-S2.42N2.64
sudo tar -C /usr/src/SierraLinuxQMIdrivers-S2.42N2.64 -xvf SierraLinuxQMIdriversS2.42N2.64.tar.bz2

The modem manager accepts the Pin, but the modem cannot be activated
How can this be repaired?

Root Shell:

mmcli -m 0 -e

error: couldn’t find the ModemManager process in the bus

Then I tried to make a installation with:
sudo dkms build --verbose -m SierraLinuxQMIdrivers -v S2.42N2.64
{ make -j4 KERNELRELEASE=6.1.0-13-amd64 -C GobiSerial && make -C GobiNet; } >> /var/lib/dkms/SierraLinuxQMIdrivers/S2.42N2.64/build/make.log 2>&1

disc_mutex is locked

unfortunately, i am not familiar with at!pcinfo Commands, but I have a backup before I tried to install EM7455, can also start from scratch again

I want to access the internet and work anywhere with my notebook

Please help me step by step.
Best regards Roburn

The gobi USB driver has been end of life.
you are using kernel 6.1.0, you can check the following MBPL USB driver:

Hi jyi jyi is your answer to my 2 posts 2 times the same?

and how do I solve this “Assuming disc_mutex is locked” ???

Best regards roburn

jyijyi · November 13, 2023, 1:20pm

why are you still compiling Gobi driver?
It should not be used anymore

pgsaris · November 14, 2023, 10:27am

Hi Roburn,
did you get it to work? I have the same problem with a Lenovo X260 using Debian 12. It worked flawlessly using Debian 11.7.
If I do not get it to work I’ll have to downgrade back to 11.7 and test live versions of 12 every now and then to check if it gets fixed.

roburn · November 14, 2023, 11:01am

Hi jyi jyi, I have downloaded everything from your link, please tell me what I have to clean up, and please give me an installation guide, otherwise I am lost. Thank you very much for your help.
Sincerely roburn

roburn · November 14, 2023, 11:12am

Hello Paul, no at the moment it doesn’t work yet, but I also had the
same experience as you, with Debian 11.
When using Debian 11 again, then only as a virtual machine.
Best regards roburn
