[Q] GALAXY S3 i9300 Unlock GSM - Android Q&A, Help & Troubleshooting

Hi guys , i need your important help.I have Samsung Galaxy S3 (i9300) ''Live Demo'' (It's a promo code).It works great but GSM is locked for every operator.
I almost rooted and i flashed OMEGA custom rom from xda.How i unlock gsm ???

Does it have an IMEI? If so you should be able to purchase one of of ebay. If they aren't available yet, they will be soon.
Edit: By "purchase one" I meant an unlock code...if you have an IMEI.

It works for every operator ?
You mean something like that cellunlocker service ?
I have an IMEI but the device its only for promo..doesn't read any network simcard.
So, this unlocker it works for every operator.Is anyway to rooted or flash custom ROM to unlock GSM function ?

Depending on how you got the custom rom installed it may already be unlocked.
no it is not unlocked.
the phone shows .... hmm how can i describe with my english
it shows in the upper line (status bar) a simcard sign with a "!" and the five strips for network receiving are empty. (when normal network reciving a part of the stripes are green)

UK galaxy ace in Brazil - Unlocking Process

Erhm, hi, i'm new in the forum and i hope i can explain properly what i have done so far and what i want to achieve posting my question here.
Basicaly i bought an used samsung galaxy ace s5830 in London it was a ''3'' locked phone. I am now in Brazil and after searching a little i was able to root the phone, get the unlock code but when i take the sim card out of the cellphone and insert the new one it doesn't ask for the unlock code, after searching in this post : http://forum.xda-developers.com/showthread.php?t=1192122 i read something about changing the rom in my cellphone, one that has the unlock screen. Ok, now i have some questions :
1- I looked around for some firmwares, like this site http://www.samfirmware.com/ in the galaxy ace section the firmwares were divided in regions, europe, america, asia, i know brazil is in america but it was writen usagalaxy, basicaly i want to know if i have to use the europe firmware only to get the unlock screen and then switch to a brazil firmware or if i can go to a ''brazilian area firmware'' directly
2- The posts about roms dont usualy talk about this, do you know a rom that is samasung ace compatible and has the unlock screen in it?
Thank you so far
I think you need some version of Latin America...I'm from Costa Rica...try a stock ROM for s5830L...

OK, so here's what i done by now. I managed to go back to a 4.1.2 version that has MG4 baseband (efs v2). afaik, on 4.1.1 you could unlock the phone through the service menu (#197328640#) method. Is it possible to downgrade to 4.1.1 with MG4 baseband and unlock the phone through the service menu?
