i am on rogers network in Canada, but i bought AT&T S3 from USA can i put rogers stock ROM on AT&T phone? any concerns i have already bricked 2 S3 by flashing wrong rom i used i9300 on SGH i747 learnt my lesson the hard way. Any issues if i put rogers stock rom on ATT phone
Thanks
should have no problem
dont flash the rogers modem on att s3..
you risk losing your imei...
can't i put Imei no back on manually and also if i do lose the imei what am i losing ?
Thanks
if you lose your imei number you will have trouble connecting to network...if you can get connected at all.
I flashed the att modem on my telus s3 awhile back and emei was 0, modem was unknown,, had no cell or data connection.
( used to do the with my old galaxy s1 and got better reception )
I nevered try to manually get my imei number back ,,, I flash back my telus modem and all was good.
I have an AT&T Galaxy S3 (Model SGH-i747) that I have unlocked and am using on Tmobile. Since it was originally an AT&T device, am I able to use Odin and simply replace the ROM with the Tmobile version (t999 I believe)? The phone is totally stock with the exception of being unlocked with a code from AT&T. It is running Android 4.1.2 Kernel Version 3.0.31-1300972. I downloaded a ROM for the Tmobile t999 with Android 4.3 and when I tried to install it Odin gave me an error: Secure check fail sbl2. I really don't like the AT&T boot screen and AT&T bloatware, and I'd like to run the factory Tmobile setup. Is this doable or are the 2 models of Galaxy S3 different enough to prevent it?
Flashing a stock T999 ROM will also try to flash a bootloader and modem that are not compatible with your i747 and may hard brick your phone.
Thank you, I appreciate the help. Do you know what options are available if I want to get rid of the AT&T boot screen and bloatware (Specifically the AT&T contacts book) while maintaining all the functionality of the device? I have been searching around on this site and google and I've been having a hard time finding information specific to this situation.
You could try a custom ROM but before flashing anything, it's a good idea to verify your bootloader and modem version.
If you are running an old bootloader and modem, you'll have to decide if you want to upgrade to use the latest custom ROMs or stick with your current bootloader and modem.
So I'm currently in Europe and I will be here for 2 more months and I would like to unlock my phone because $4.19 a minute is ridiculous. However tmobile support is being, let's say very smart. The first representative said "just visit you're nearest tmobile store and we'll help you out there." After I had already told them I was in a country without tmobile. So I was wondering if there was any way to do this for free? I really don't want to have to spend any more money right now. I'm currently running liquidsmooth lollipops latest build. And I really don't want to have to revert to stock because I currently have Internet speeds of 85kb/s and that would take ages to download and then reset up my phone. All help is greatly appreciated.

Which version should i downgrade to, and could you give me a like to a method of unlocking it?
Before flashing any TW ROMs via Odin, confirm the bootloader and modem on your phone.
I'm not sure but if the T999 is like the i747 (ATT s3 version), you cannot downgrade the bootloader from 4.3 to a lower version. Doing so may brick the phone.
If you are on a 4.1.1 or 4.1.2 bootloader, you should be able to downgrade to stock 4.1.1 and you may be able to unlock for free using this method: http://forum.xda-developers.com/showthread.php?t=2014982
If you cannot downgrade to stock 4.1.1, you'll need to buy an unlock code and enter it using a stock Samsung dialler.
Hey guy I just unlocked an old SGS3 for AT&T SGH-I747. Now i plan on giving the phone to my mom for her to use since her current phone is a POS... how would i go about getting tmobile firmware on it for her without bricking. I know i have to root first and then Recovery then Rom, but is it safe and stable to run TMO rom on the att model of the S3. I just want to make sure that i go about this the rite way.
Thanks in advance
Will she be using T-Mobile data? The i747 does not natively support aws frequencies so that may be a problem. Voice calls would probably work.
You can't flash the t999 modem and bootloader to the i747 so forget about flashing a T-Mobile rom to i747.
Pray tell: How did you Un-Lock it?
I haven't been able to get past the debug screen?
Any info is appreciated, Thanks!
