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...

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 ?

Possible you can read the rules .
This is not the forum you want you do not have I9300/ I9305

Hum… I’m not quite sure. Have you tried contacting your service provider or Samsung directly? Sometimes (especially with legal issues these days) your service provider can be the best place to ask about unlocking your device.

s3 not registered on network

Hi all ,
i bought s3 i9300 it was a european model with region lock my sim in egypt worked on it , i tried to flash another stock rom after that my sim didn't work and if i try to make any call it tells me not registered on network i tried many apps root every thing on internet that didn't work , i gave it to a guy who used z3x samsung tool and some boxes and cables and he couldn't lock it on 4.1.2 so he downgraded it to ICS 4.0.4 and he managed to make my sim work , is there any way to get back to 4.1.2 and make this network problem go away ? thanks in advance .
Unlikely, if it is network (not region) locked then 4.1 and later will cause it to lock again.
Without the genuine unlock code from the original network you cannot unlock at present, 4.0 will cause SDS to your emmc chip.
Most network registration issues at the moment are caused by people not reading about the efs change, before flashing to EMG rom. This might be your problem as well, read sticky thread in general forum: efs 'know this stuff'.
