Possibly dysfunctional as a cell phone

[tckosvic]

i do not recomend firmware update, at least not directly.

https://github.com/Biktorgj/pinephone_mo.../tag/0.5.5 and see notes.

NOTES:

• When using a Pinephone Pro, make sure you enable USB persist:
  • In
    
    Code:

    /usr/lib/udev/rules.d/80-modem-eg25.rules
  • ACTION=="add", SUBSYSTEM=="usb", DRIVERS=="usb", ENV{DEVTYPE}=="usb_device", ATTRS{idVendor}=="2c7c", ATTRS{idProduct}=="0125", ATTR{power/persist}="1"
    

this might be related to call problems.

I looked at the file that you suggested.  The only change I can see to make is:  ATTR{power/persist}="0"  --->  ATTR{power/persist}="1"
All the other items are already as you listed.   Is that the change you suggested to make?
Also, briefly, what am I changing from and to and why?.

thanks,   tom kosvic
