Hi there,
I just got a new Lenovo X1 Extreme Gen 4 that comes with a Snapdragon X55
WWAN modem by Foxconn. I'm running Arch Linux w/ kernel 5.15.5,
ModemManager 1.18.4, libmbim 1.26.2 and libqmi 1.30.2.
The X55 seems to be supported for older firmware versions (<= v48?) after
setting up the FCC u

Fortunately, I can downgrade (via a Windows installation I have on a USB

Hi there,
Lenovo just published a new firmware for the T99W175 / Foxconn SDX55
5G modem on LVFS [1] that effectively soft-bricks the modem under
Linux as the FCC unlock no longer works.
I can boot up Windows and downgrade the firmware, but would be
interested in a more permanent fix.
What would

Hi Bjørn,
thanks for your reply! I don't think that the lenovo-wwan-dpr snap
implements the OTP unlocking mechanism.
Lenovo also just posted in their forum [1] that the new firmware
deliberately broke the unlock used by ModemManager. So that was
probably my last Lenovo laptop...

understand (using static analysis only) what is actually sent to the
modem.

Hi there,
as Lenovo couldn't fix my ThinkPad X1E4 (featuring an SDX55) I got a P1G5
as a replacement, that, however, comes with a FM350-GL as WWAN modem. I
guess we need to play the FCC unlock game again (as it does not work out of
the box), but first wanted to ask if anyone has any experience wit
Hello everyone,
meanwhile I have an idea how the FCC unlock for the FM350-GL works:
1. Retrieve radio state (only continue iff locked [== 0])
2. Get challenge from modem
via mbim_message_intel_mutual_authentication_fcc_lock_set_new
3. Compute a SHA256 hash
4. Unlock the modem
using mbim_message_i
Just noticed that I did not reply to the list... Next try...

Hello again,
I got a prototype working that successfully unlocks my modem via
/dev/wwan0at0. Currently I have that device name hardcoded. Is there a way
to infer it from the mbim device name?
Thanks,
Thilo
Problem solved. Just submitted a MR [1] for the unlock script.
Thanks,
Thilo
