So it may really be that they've changed the unlock method already :/ Are you able to flash back v48, or is the downgrade path not possible? My firmware version in the SDX55 I have is T99W175.F0.0.0.5.8.TF.007. Could you run this just to confirm? $ sudo qmicli -d /dev/wwan0mbim0 -p --dms-foxconn-set-fcc-authentication=0 -v Regarding the lenovo-wwan-dpr in https://snapcraft.io/lenovo-wwan-dpr, does it help to unlock the module in the newer firmware versions? -- Aleksander https://aleksander.es
