Hey guys.. I'm new to this forum and to flashing ROMs and all that so I need your help..
I used the search option and didn't find a clear answer to this..
I have bought about a month ago an at&t SGS3 SGH-i747 and I am not very happy with the current OS (android 4.1.1 at&t stock ROM) and I want to upgrade it to 4.1.2. After searching google a bit i found out that there IS an official 4.1.2 android from at&t for my device and wherever I go they say to go to settings, about device, software update and update my phone from there but it says that there is no update.
I have searched for a ROM on sammobile and only found a 4.0.4 ROM for my phone.
However, I found out that there is a 4.1.2 ROM for SGS3 SGH-i747M, and some people say that their ROMs will work on my device and some say they won't.
Can someone tell me, if I install a Rogers (for example) i747M ROM on my device will it work without problem? I don't want to stay with the at&t ROM because it has too many limitations on them.
I prefer not to install custom ROMs because they are all a bit unstable..
Sorry if I have bad English, tried my best..
First off an (att) rom will work with a (rogers) phone. I'm using one right now.
Secondly, if you do manage to install a (rogers) rom on your s3 it will probably be missing apn settings and you'll have rogers apps.
Lastly, through my experience with custom roms, I have found that they are far more stable then stock, if you're looking for a good custom touchwiz rom. Look at hyperdrive

What you are describing on Sammobile are the stock firmwares that are flashed through a program called Odin. If you tried flashing a Rogers image, you could potentially brick your phone, or as the user above said, there would be a lot of issues since that is not the firmware for AT&T. Are you rooted? If you are, that is what is causing the upgrade issue, since you have to be 100% stock.

Thanks for your answer. Well, if you say that custom roms are more stable than stock, I won't argue. Just some friends told me otherwise.
I'll try to find a good rom that suits me.
Btw, I don't care if ill have Rogers apps or AT&T apps, they are both useless to me. I just don't want to brick my phone.

I didn't flash a Rogers rom because I couldn't find a clear answer that says that it will not brick my phone. I just seen some people ask about it and didn't get an answer either. I have tried to unroot and flash a stock rom from "samsung-updates.com", a 4.1.1. Its the same as the one that I already had. Still, no update available.

If you flash a ODIN package for rogers on an AT&T phone you may brick it due to bootloader and modem
if you flash a custom zip based on an AT&T rom from XDA you won't brick since they don't contain bootloader or a modem
hope this helps

Hi there!
I have a Galaxy S3 SGH T999 version. It has Tmobile rom, but I am trying to install windmobile stock rom via odin (3.07 - tried other older versions) and it fails the secure check.
Is there way to resolve this? I really want to install the stock windmoile rom , and did lot of searching and couldn't really find a lot of info, except that someone with AT&T galaxy S3 had same issue when installing Rogers rom.
I would really appreciate it, thank you!

If you continue trying to ODIN flash firmware which is not intended for your specific phone
you will end up with a nice shiny brick sooner or later, in your case it will be sooner.
If you want the appearance of a windows phone, the best way to do it is to find themes and
launchers which make the phone look like a winmobile phone.
There are a lot of themes and launchers at the play store which do exactly what you are looking for.
Check it out B4 it's too late..
It's not a windows phone style, I think you misunderstood me.
I just don't like T-mobile rom and its bloatware. The windmobile rom is more clean.
Both phones models are same, exact. I don't see how it would be bricked. It's just a mismatch of bootloader, thus secure check fails. I've seen people with windmobile SGH T999V flash T-mobile rom, and it works perfectly.
It's just SGH T999 tmobile version isn't able to install SGH T999V (windmobile, mobilicity) canadian variant roms because of some block T-mobile setup. Some people had done this, but didn't specificy how though.
I would like to know that please.
If you don't like bloat, then remove it. Don't flash another carrier's rom.
I've galaxy s3 for tmobile and it is currently on 4.1.1 T999UVDLJA.
I followed this method to unlock it and right now I am using the phone on H2OWireless (MVNO on AT&T network), everything is working fine (not tested data plan yet).
http://forum.xda-developers.com/showpost.php?p=34661189&postcount=1
Now my question is if I upgrade the OS in future to say stock from TMO 4.1.2 (when they release) or non-stock 4.2.2 rom then will my unlock go away or it is factory unlocked now?

No, once your phone is unlocked it stays that way regardless of flashing any roms.
Flashing roms has no effect on the locked or unlocked status of the phone.
Even a OTA update has no effect on the locked or unlocked status of the phone.

Are you sure? Because this is different method than entering an unlocked provider by service provider. I just want to make sure before I step out of 4.1.1. And again it's possible to move back to stock right? Is there anything like iphone where you must have SHA BLOBS to get back to a specific version? I am an iphone guy and getting first time handson android phone litterally!
I tried getting one from tmobile but since I am not a tmobile customer the refused.

Yes you can go back to the stock rom by Odin flashing your phone at any time.
Doing that has no effect on the phone's locked or unlocked status.
Sorry I have no idea about the iphone's BLOBS

Can you help or direct me to any link on this forum which lists all custom ROMs for TMO GS3 please.
And if possible in your opinion which would be the best? (I know it's wide scope question but if you can help that would be great )

Here is a link for a lot of Tmobile custom roms. Any of the custom roms there will work with a
Tmobile S3 locked or unlocked phone or a AT&T S3 unlocked phone: http://forum.xda-developers.com/forumdisplay.php?f=1645
My personal preference for custom rom is the "Wicked v9.1" rom.
In my opinion after flashing all other custom roms for Tmobile T999 phones the "Wicked v9.1"
custom rom is clearly the best rom which is currently available for our phones.
It's not only the most trouble free & reliable custom rom but cosmetically speaking it looks like a retail commercial product.
I would recommend that you flash that first, check out all it's features and options carefully then make a nandroid backup.
Here is the link to the Wicked v9.1 custom rom: http://forum.xda-developers.com/showthread.php?t=1804260
After doing that flash a lot of the other roms which are available and check those out so you can have a better idea
as to what the differences are after doing a lot of comparing.
Good Luck!
Hey guys so I decide to get the SGH-147 AT&T S3 off of ebay for MetroPCS which enabled me to get a 2 year squaretrade warranty. After looking back at it now, I feel it might have been a bad idea since Metro has a MIR 349.99 deal for their S3 version which would mean easier android update since it would be on Metro servers if I'm not mistaken. Anyway I can't return the ebay phone now unless there is some software or hardware problems within 30 days
So my problem
I am stuck on 4.1.1 on Kies and when I check for update, because the phone is based on AT&T servers, it won't work since I'm on Metro. I wanted to see if there is anyway for me to update my phone to 4.3 which is the current version. Although, I've heard some people have 4.3 problems?
If that's not advisable, could y'all tell me how I could atleast get to Android 4.1.2? Also is there a 4.4 update in the works?
I just got the phone today and would like to be running on something better than 4.1.1
should I flash the AT&T phone to a MetroPCS ROM lol, if any of those are actually available, or if I were to flash, should I flash it to Tmobile?
First off, if its I747, you MUST flash only those Roms. No others. Now, that's indeed a nice phone with LTE Antenna.
You really heard correct. The 4.3 upgrade from the carrier (ATT for you) /Samsung has a lot of issues. I wouldn't do it for any reason. Particularly on T-Mo network, you will have severe signal issues as reported by others. In addition, it now flashes an EFuse onto your phone along with locked bootloader and other scary stuff.I really would not do it.
Lastly, XDA is organized by devices. So even though you are a T-Mo/Metro PCS customer, you will have to post on AT&T SGS3 forum over there.
Speaking of Rom update, Please visit Root66 Thread for this device. You will find Rooted version of your Current Rom. Dunno why but he does not have 4.2.x for you. Please do your research someone else must have posted it.
Now speaking to 4.3, yes there is a way to get 4.3 on your phone without the issues I mentioned above. But first you will have to flash a Custom recovery such as CWM or TWRP with the help of ODIN on your phone. Again do your research well. Once those are in place, take a look at this thread. It will provide 4.3 experience without ANY concerns or issues. Read it carefully and then read some more. Good Luck.

THANK YOU! Looks like I got a lot of phone work to do over the weekend. SO do you think it was good/should I stick with this AT&T S3 or should I try to sell it for a discount and buy a Metro PCS S3? The ebay buyer won't take my phone back unless there is a hardware or software problem inherent to phone...unless I fake one ?
If it was me, I'd keep the phone. Metro's S3 does not have LTE Antenna. You'd have been stuck at lower speeds.

Metro's s3 does have lte
As for the OP you can flash at&t or T-Mobile ROMs it really doesn't matter because they are backwards compatible (I have done it) and you can flash 4.3 ROMs if you don't want to take the official 4.3 update which you can easily do with Odin without the need for kies or ota.. Now, I suggest the first thing you do is flash a custom recovery and then experiment with 4.3 ROMs, if you keep having problems flash 4.1.2 roms.. There are some things you need to do though to get 4.3 up and running so I suggest you read up on it first. Good luck my friend!

It was my impression he wanted Stock Touchwiz Roms not AOSP.
Thanks for letting me know Metro has T999L

Hey guys how are you all today? I have a quick question... I have rooted and installed MANY custom Roms on MANY different devices.... but never came across this problem yet. I live in Canada and I recently purchased yet another S3, but it is a US model i747 from AT&T.... now my question is, can I install stock rooted Bell or Rogers firmware on the device? Im currently running CM11 and it is a great ROM, however, when I had my S4 I was running Foxhound ROM and loved it as it was the best of both worlds. Now I would like to go back to a stock rooted ROM and use Xposed Framework so I can keep the stock Touchwiz functions, but would like to customize it to give it the AOSP look. So, am I able to flash stock rooted Bell firmware on an AT&T deviceÉ I know this is a newbie question but ive never owned a US device before so I never encountered this problem. Thank you all in advance for helping me clarify this.... Ive tried searching but didnt come up with a solid answer through search. Thanks again.
Jeff
Anybody
Do you have the 4.3 bootloader on your phone? If you do, flashing an older bootloader will brick the phone.
I would not try to flash a stock Canadian ROM as that may also brick your phone because the Canadian and US models appear to use different bootloaders.
Thank you for the reply dude.... no Im running cm11 4.4.2 but on MG2 bootloader... if this helps? I just figured that since the devices are basically the same and you can flash the same custom ROMS that you could POSSIBLY flash stock rooted ROMS from either country as well. You think its possible? Thanks again in advance for the reply!!
Jeff
Going along with what audit13 was saying, you should be safe as long as the ROM doesn't install a modem/baseband or bootloader.
Without the modem and bootloader the ROMs are interchangeable for the i747 and i747M.
If you install a Canadian bootloader there is an excellent chance you will brick your phone.

I hope this is the correct section for this question. I rooted my s3 installed a custom rom. more than once! switched recovery a few times. basically played with my phone. Well now i need the stock att rom. I have the stock recovery. Yes i did search for Stock recovery but there are no ATT apps with them? Im on ST right now and have a guy who wants it for his att account. but wants all the apps?? odd yeah. So where d i get the stock att apps that came with the phone originally?

Welcome to the forum! Would you recall what Android version you were on prior to flashing the custom ROM? Ideally you would want to return to the same version in order not to risk a brick. You can also check your phone settings and see what the firmware parameters are. If your baseband says UCUEMJB, then you would have to go to 4.3 but if it's UCDLK3, then you could go to 4.1.1 or 4.3. Flashing a complete stock image should install the basic AT&T apps and settings. Anything else, you can add from the Play Store
