I flashed SFOS version 4.4.0.64 and also version 4.4.0.68 several times without flashing back to Android.
I could not get the mobile IPv4 internet connection to work.
Interestingly, there were different behaviors.
Sometimes I didn’t get an IPv4 address at all.
ofono: 0x93c22e0 DUAL no IPv4 address set
(see log in bug report)
After the next flashing, I got an IPv4 address and the route was entered correctly, but no internet connection was possible.

I also tried the SIM switch, but in slot 2 my SIM card doesn’t work at all at first.
The SIM was recognized and the PIN was requested, but no connection could be established.
Neither telephony nor data (network search runs forever).
After further flash attempts, the card worked in Slot 2, but also without an IPv4 connection.
Also I tried restarting ofono but that didn’t change anything.
Only after I flashed Android 62.0.A.3.109 again with Emma, tested the IPv4 connection and flashed SFOS 4.4.0.64 from there did I have an IPv4 internet connection again.

Then I made an update to SFOS 4.4.0.68 via the GUI and after that no IPv4 connection is possible anymore.
ofono: 0x9a07b70 DUAL no IPv4 address set
(see log in bug report)
Maybe i have to Flash Android 62.0.A.3.109 again with Emma and then directly SFOS 4.4.0.68?
Maybe i need another Android Baseband Version for SFOS 4.4.0.68?
Maybe there is a bug in SFOS 4.4.0.68?
Does anyone have a hint?
I gave it one more try and it worked for me as follows:
I flashed Android 62.0.A.3.109 again with Emma,
tested the IPv4 connection on Android,
flashed directly to SFOS 4.4.0.68.
