So I want to know if I am able to downgrade my radio. I heard that downgrading firmware itself WILL cause a brick but how about just flashing the radio? Ever since I would mess with stocks, when I updated to 4.4.4 radio updated and now I am no longer to roam (connect to movistar network at least) I used to have a sim for movistar (mexico) which worked perfectly fine at 4.2 but when I did the upgrade it started to slowly fail to a complete stop. It was funny because a movistar sim would roam to t-mobile or sometimes even at&t. Now that I moved to the united states I got tmobile since it offers free roaming in Mexico, but bad news, t-mobile roams to movistar and now I am unable to roam. Its like movistar doesn't want my phone at all.
So back to my question, will downgrading radio cause a brick?
