I have a Samsung SGH-T589 (Gravity Smart), originally from T-Mobile, but now unlocked. Since I'm in Brazil, tha 3G connection doesn't work. After some (and for some I mean months) time of research, I figured out that T-Mobile Works on a diferent 3G frequency than brazilian ops. But, I've also figured out that maybe (and just maybe) could be possible fix this by flashing the SGH-T589W (Gravity Smart/Galaxy Q) or SGH-T589R firmware on this phone. There were no problems related until now... but I'm having trouble to find this firmware. Tryied Samfirmware, Sampro, and many others...
Anyone have this file or I should just retire this phone once and forever?
Well, it wouldn't be helped by the t589W because that also uses the weird 1700/2100 AWS bands for 3G service. The R would be the way to go, if it were possible, but even if it did flash successfully, the phone still has a hardware limitation where it just doesn't support other bands, despite what radio/modem you could install.
If you wanna try though, just for the heck of it (at your OWN risk - I do not think this will work. Not likely to hard brick it, but will probably need to restock with the correct firmware if it fails):
And you'll want the official firmware flashing Odin version for the phone, because for some reason it doesn't work with the regular Odin ones:
