3g fail

[#1]

Hi, i sent my x8 to technical assistance and they reppair my problem and updated my phone. But now, my 3g doesn't work anymore.

I'm in brazil, using vivo operadora. I have a e15i model, with 2.1.1.A.0.6 version and 015baseband.

I want my 3g back!!!

Help me to do it!

Have you tried the following,

Menu > Settings > Sony Ericsson > Settings download > Choose your network provider > wait for it to download the settings.

Try the above and let me know if it works for you.
