I have struggle with 3G/4G connection and therefore think of replacing the antenna. The antenna is a small part of the core module.
This might be interesting for people with a broken core module. You could either send me the broken core module or disconnect the antenna from it. It’s easy.
I live in Germany. Please leave me a message if you got something to sell me.
Hey, thanks for your nice suggestion. I have done everythink I can think of. Both, on software and hardware side
So yes, I have disconnected the antenna and cleaned the connectors. Also, it’s definetly a hardware problem, as different versions of the OS and different sim cards have no effect on it. I hope it’s the antenna. If not, it’s a problem on the core module.
Do you have any other ideas?
BTW: 2g works perfectly, 3G works sometimes for about 10 minutes after I enable it. Afterwards i get no signal at all. If I switch to 2G only mode, i get signal again.
