I have an MX5 and i can’t upgrade or downgrade for the international version. when I try to do it, it says to me: “Firmware Corrupt”.
When i recieved the smartphone I updated to 184.108.40.206A version, but this version doesn’t have Portuguese language, so in this moment I have 220.127.116.11A version, but doesn’t work with Google Play Services.
I am Portuguese and I need the language in PT. I bought the smartphone in Spain.
Someone can tell me why i can’t install the international version?
