I'm having some trouble with a galaxy note 2 , N7100. This is a chinese phone, it came with a chinese version of JB, i think it was 4.2.
After some attempt i flash it to an european version. But now this happens, when i try to make a phone call using a mobile network the connection is established but i can't hear what the other person is saying on the other side and he cant hear me as well. If i try to make a call using voip (e.g. Skype) it works without any problem.
This situation happens with the european ROM, chinese ROM and a CyanogenMod ROM. Both the european and chinese ROM are official, i have made de download from sammobile.
Does anyone know how to resolve this?
Obs. When flashing the european ROM through any version of Odin it fails on the modem.bin, but that doesn't happened with the chinese rom.
I flash the european version using this method... Install a custom recovery, install a cyanogenmod rom already rooted, install mobile odin and flash the european rom through there
