[Q] Baseband and radio for TIM Brasil

Hello there
I have a LG Optimus 2X and i am having a problem, and really don´t understand about baseband, radio frequencies stuff
It works fine with Vivo (Sao Paulo, Brazil) and I tried to insert a TIM sim-card and it gets no service at all
I even could use a Claro sim-card here and it worked fine, since the device is not sim-locked
How do I fix it to work with all operators ? Since I bought it as an unlocked device that should work with all carriers ?
Tks

I had a O2X and I live in Minas Gerais. Here Tim has 3g only in 850mhz frequency. Only P990h has UMTS in 850mhz, so you have to know what model is your mobile. If I had bought the international P990 I would have problems with Tim. Do you know what version your mobile is?

Hi guys,
First of all sorry for my english, i know is not good but im doing my best.
Recently buyed an XT1058 (Iusacell - Mexico)... I dont know what is going on but works funny.
The active display works just sometimes and others not... I heard about this kind of problems whit the update that came from iusacell so... I want to change the firmware but i dont know whit one its compatible.
¿Somebody can help me whit this?
I read this thread: http://forum.xda-developers.com/moto-x/general/ref-how-to-root-4-4-links-guides-t2603358
But doesnt say anything about my xt1058 from iusacell.
Please..
EDIT: Any XT1058 is compatible... Tested.

Have you updated from 4.2.2 to 4.4.4?
I have the same XT1058 ftom Iusacell Mexico and i cant update the phone.
There is also no LTE signal, although my carrier and sim supports LTE.
