This is probably a stupid question but hey, can't hurt to get some input.
I have recently found myself in possession of an AT&T Galaxy Mega. I have T-Mobile as my carrier so have no intention of using the built in 4G from AT&T. Can I flash a T Mobile rom and baseband to it? I assume this will brick it and I am better off just leaving it be and using it as a plain wifi-only tablet but want to verify with the experts.
I am no novice to flashing/roming and the occasional brick recovery
Sorry, but you can't flash ANY rom to the ATT Mega. No one has been able to unlock the bootloader.
But, I'm sure, if you search, you will find folks are using a t-mobile sim in the ATT version.

Yeah, was hoping a stock rom from another carrier wouldn't need an unlocked loader. Ah well,, am rooted and just waiting for the official 4.4 then.
Thanks for the input!

What should I do to get it on the AT&T network?
I have already purchased the phone and the sim card from AT&T is already on its way here.
I have tried searching but I only find threads on rooting and flash custom roms but I havent found one that states which rom would work for International phone on ATT's network
Any help would be appreciated. Cause I am now worried I bought a $700 paper weight I cant use.

The international one WILL work on at&t, I think the op was kind of misleading.
It seems slim thought you were asking if international roms will work on US S3.
Tbh I thought the same.
Any rom in the development section here will work on your phone. No problem.
Just as long as its the international model, GT-I9300.

My bad. Yeah, it's one of those confusing sentences. If you have I9300 then whatever is in this board will work.

Sorry for the poorly phrased sentence, I am a product of NYC public school system. And thanks to you both for your replies.
I recently bought my galaxy note i717m from Bell in Canada and unlocked it with network unlock code purchased on internet. Then, I got someone from kijiji to root my phone and upgraded from ics to jb and made the phone to work with wind/mobilicity. I am now using a wind sim card on my phone but i found out that the jb system is very buggy and crashed too often, Anyone knows how to downgrade jb to ics or recommend a more stable jb rom? Does downgrading to ics or changing to a new rom will make my phone not supporting wind/mobilicity anymore? I dont know anything about android btw, anyone kind enough to write me a simple guide? Thanks a lot!

how to check?
Okay restart the phone by pressing power+ volume up and down at the same time until you see the first Samsung logo tht will take you to recovery that's is how you will see. Seems like you are new to this. Most of all the jb roms out there are good but buggy and also battery drainers I speak of past experience long story short if you want stability keep stock ics until jb is officially released...

Im now using Wind mobile, it is using the same frequency as tmobile. I just want to downgrade to ICS without touching on other things so that my phone can still support the AWS 1700 frequency.

Nice guide, thanks so much! However, my phone was bought from BELL store in Canada,does it the same stock rom as AT&T? When it was bought, it was locked to bell, unrooted and only support 1900/PCS frequency, does not support 1700/AWS frequency till I got someone from kijiji to help me turn on the AWS radio frequency support in the phone by flashing rom, rooting and stuff. If I follow your guide, would my phone get locked and lost support to AWS frequency?

This one you have to Odin it but ur ain't hard just make sure you back up all of your internal sdcard stuff since this Odin will wipe the crap out of the system lol happened to me luckily the external SD didn't got wiped. By the way
By doing this you will loose root and also clockworkmod you have to re root the phone

That means the phone would not support wind sim card and its AWS frequency just like when it was bought at the bell store, locked?

That is all you can do when you "unlock" your phone. You remove sim card based carrier restrictions. Once unlocked you can take an att phone and put in a tmobile sim and it might work! But that's all it can do.
You might be thinking of giving your phone "root access" if you want to do more. Once you root a phone you can remove preinstalled software or bloat. You can install custom roms. You can enable tethering when you might not of before... and so on.....
Rooting and unlocking are two different things. I hope this answers your question.

I figured you knew what rooting was because you have a decent amount of posts. I just wrote it so anyone uneducated would understand a lil better.
Hi guys, I'm thinking about trading my Galaxy S4 for an AT&T branded HTC One. I was curious if I were to put a Tmobile Rom on it with a Tmobile sim card would wifi calling be functional? I absolutely need wifi calling because I don't get great service at home or work. Thanks for your time!

If the rom supports wifi calling then you're golden.
If you put a T-mobile ROM on your AT&T device, you run a serious risk of bricking the unit. You can get a T-mobile SIM working on it by doing a GSM unlock, and you can flash any AT&T ROM you want, but Wi-Fi calling won't work with the AT&T ROMs.

Negra,
No offense but I'm sorry to say you're not right that he'll brick his device, I have an AT&T HTC One, unlocked using a code, and root it myself following the easy to follow guide available on XDA for AT&T HTC One. Also I have tried almost all 4.3 Rooted T-Mobile ROMs including Stock as well as Custom ones and have not yet bricked the device.
I appreciate all the hard work and support provided by XDA devs and mods and other users.
I installed these roms in order to get the wifi calling on my device.
FIX:
UPDATE THE RADIO TO 4A.21.3263.03_10.38m.1157.04L AND FLASH AN ADNROID 4.3 T-MOBILE WIFI CALLING SUPPORTED ROM, it worked on my HTC AT&T ONE, I hope it work for others.
TIP for noobs like me, ALWAYS WIPE before flashing a different ROM/Firmware and "READ the INSTRUCTIONS".

Eyezayah, can you please change the subject to TMOBILE WIFI CALLING ON AT&T UNLOCKED PHONE. There are too many wifi calling threads floating around.
I recently unlocked an S3 for a friend, I did the whole downgrade to 4.1.1 method then the *#197338640# now my question is this, if she upgrades the phone when she's on the new network back to 4.1.2 will it ruin the phone being unlocked? Thanks, first time I've ever done this.

gt i9300 international SIII has no locked bootloader (only one I know is verizon one). so either you are in the wrong SIII forum or you have done something unnecessary...
Your right, sorry. Like I said I did this for a friend I don't own an S3 so I didn't know where to post. Thanks

No, SIM unlock is permanent and can not be reverted by flashing OTA.
