Hint needed; cannot register...

[nlincke]

Hey,

i know that this repo will no longer be developed. But i would like to get it working on my x1g7 before i try the pci driver....

You would realy make me very happy if one of you could help me get it working...

I got the modem up...

mmcli -m 0                                                                                       :(

Looks like the fdd lock is still active: https://github.com/xmm7360/xmm7360-usb-modeswitch#fcc-lock

[nlincke]

Thanks fpr the replay. I did what was described there. I run at@nvm:fix_cat_fcclock.fcclock_mode=0 and now i am able to change CFUN etc. Anyway, it does not change anything....

[nlincke]

Do you have any idea what could went wrong. Is it possible to check if the FCC Lock is successfully removed?

[nlincke]

In case anyone finds this. I yould get it to work. I had to use the modem once under windows. After this I was able to use it under linux (Arch on an Lenovo Thinkpad X1 gen7) as well. In preparation of the PCI driver, I also disable the pin of the SIM...

So I guess the FCC hack did not work for me?!? Or i did something wrong...
