Modem firmware update

[antiX-Dave]

Well bugger. I did the update and lost the usages of calls. (SMS/Internet works)
Tried changing the various modem settings to what they were with no luck
Tried changing the modem settings as specified here: https://forum.pine64.org/showthread.php?...4#pid80714
Tried disabling the the VoLTE as mentioned here: https://forum.pine64.org/showthread.php?...1#pid85971
Also updated the kernel from 5.9 to 5.10 via the repo. Still no luck.

Anyone else have the loss of call function / may have another solution?

Edit:
tried going the other way and enabling the VoLTE via post https://forum.pine64.org/showthread.php?...8#pid85368 still no joy.
