I just installed e 0.18 os on two LG G5 H850 and neither are recognizing sim. Sometimes “invalid Sim” displays but in any case no service. Otherwise install seems fine. A little reading says that now the devices are on ‘android 10’ the last factory modem firmware ( for android 8.1) is a likely culprit. Device is not asking me for a sim code.
I don’t think LG supported firmware past android 8.1 if they did I don’t know how to find it.
Any suggestions on what firmware to try? It may be also a different issue - this is just a guess and I am not versed in these things.
Appreciate any advice and please excuse my technical inexperience.
