LTE not attaching anymore
-
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 :

The cell provider see the device offline so Im thinking its not even trying?
thanks!
