<![CDATA[Bug two sim cards only one is working perfect]]>Hello all,

I'm not shure if you have the same bug. When i have one simcard in everything works fine with and without WLAN.

When i put the second sim card in everything works fine, when WLAN is on. When I put off WLAN only sim card slot 2 is available and i can only phone with sim card 2 sim card 1 is off. When I put WLAN in again sim card 1 is back again and i'm reachable and can call with sim 1.

I have changed the simcards to the other slot, but same result. Slot 2 is Working fine slot 1 not.

Thanks for your feedback

Don't you think, that it's rather the sim-slot than the fact, that the card is "foreign"?

Without data and WLAN only the sim card in my country is working. Foreign sim cards run only with data and WLAN.

Its fins for me. Put data on and its okay.

I did it also!
I format after every step the data with twrp and now FP3 is running with the newest image.
Crazy, that the old images are running without formatting data and since End of January only with formatting over twrp.

thanks to both of you

@FP2andFP3-User not surewhy it does not work with fastboot.
Did you try it with twrp already?

I think, the problem is maybe the data wiping.....
@Luksus
Now E foundation is flashed, because after testing no Android and no old Image was running....e foundation is running now with android 10....Do you have an idea?

Today i tried again some new builds, same result (also the last build from yesterday does not work).

What is also tried is to connect per ssh to 10.15.19.82 after booting the phone, but fails with:

Connection refused

Output of lsusb contains the line where the ssh connection should work:

  iSerial                 3 GNU/Linux Device on rndis0 10.15.19.82

Any (new) ideas for debugging?
