Hi all after wifi not working anymore I bought a refurbished motherboard for my 9505 LTE version. After replacing it wifi is working great but I can't seem to be able to connect to 3G. In info menu (*#*#4636#*#*) I read -voice network: GSM and -data network: EDGE, no matter what I set in preferred network type. I contacted phone company (3 Italy) and they say mi sim card is correctly registered on the network and I should get at least H+.
Tried all the latest modem/bootloader avaiable, now I am on I9505XXUHQC1 (GSM/NON-HLOS COMBINED).
Also tried manual network selection and I can only have signal if I set 2G as preferred network type in Settings-WiFi and Mobile-Mobile network.
