      I have a couple of older GPY working wiht no issues in LTE CAT-M. Since I received a new batch ( with the new firmware), im not able to attach to LTE, using the exact same code and sim card batch ( tested on multiple gpy).

      Can I roll-back the modem firmware to the 'working version', or is there anything I can do to troubleshoot?

      What I did so far :

      <<< Welcome to the SQN3330 firmware updater [1.2.6] >>>
      >>> GPy with firmware version 1.20.2.r6
      Your modem is in application mode. Here is the current version:
      UE5.4.0.2
      LR5.4.1.0-50523
