Modem firmware update

[dcinoz]

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.

Check my post as I've corrected a step that claimed to be Reboot the modem to apply the settings whereas it sets full functionality AND resets the modem (presume to default settings). AT+CFUN=1,1 should not be needed at all (and it resets to defaults).
This comes from Quectel BG96 AT command manual so presumably correct for EG25 too.
If anything you can do AT+CFUN=1,0 to set full functionality and keep other settings.

I don't have VoLTE support via Alidmobile but incoming calls ring, outgoing work, SMS also, haven't checked data but presume aok for me on firmware EG25GGBR07A08M2G_01.003.01.003.
