Baseband Unknown Xperia Z1

[afer31]

Hi,

I keep on having this issue with my phone running 14.4.A.0.157 (Kitkat), Baseband unknown appearing in About Phone. That cause my Wifi not to work neither the Bluetooth or NFC and SIM is not detected. I send it to a center to fixed it, and it work for some weeks, then it came back. I tried repairing with Pc Companion and Bridge, also using flashtools but the error is present. Does anybody know how to fix it and what cause it?

It could be a third party app, when you repair your phone with PCC does it work for few days?

Hi, yes uliwooly, it works for a few days. Then the same problem occurs.

Then it's an app acting up that creates this issue.

It seems my phone is damaged, the board is not functioning properly, that's why I have this problem. No more phone
