As of right now, the roms for your S3 are not meant to be used on other S3 variants. Bricks might happens or a soft one might happen. Before flashing a Rom make sure you are in the right development section an you read the entire op, twice. Until other devs or experienced users find a way to make them cross compatible, please refrain from using other carriers S3 roms.
Also wind mobile an Tmobile are interchangeable, just don't flash the modems.
ONLY FLASH THE ROMS IN THIS FORUM!

I second this, guys PLEASE don't risk it. It is not worth it. Right now I think most devs are working on their own ROMs, but we should have a patch soon to allow cross-compatibility.
think some peeps are confused by whats before tmo development. (AT&T, T-Mobile, Sprint, Verizon Samsung Galaxy S III) just my opinion but good idea on thread.
Mr Highway:
Could you start another thread for Windmobile Android Development?
In the past all Windmobile phones are just T-mobile phone rebadge.
In this case, it does not in terms of kernels....(and may be baseband)
I am working on this so that all roms will work on all carriers

AMEN!! Some fool I know ALREADY called me with a bricked gs3! I'm gonna sit back and let the pros do their thing, and that's DEFINITELY the safest bet!
thanks for the reminder and jsut to make sure ....
i have rogers sgh-i747
i want to be in this AT&T, T-Mobile, Sprint, Verizon Samsung Galaxy S III - xda-developers thread for everything correct ?
and not in the Samsung Galaxy S III I9300 thread ?
I keep seeing posts about ROMs that can work on these variants of galaxy S3s. Now correct me if I'm wrong, but aren't the ROMs supposed to be specific to GSM or CDMA? When I flashed windows based roms on my touch pro II, that was one of the things to look out for. Is it possible to create a ROM for all carriers?

Yes and no.
With the use of aroma-installer, we could set it up to detect your phone type (well, not we....I don't know that much about it but I saw the thread discussing this) and aroma would be able to install the necessary files based on your phone.
As of now, for instance, mine works across all GSM carriers. clark44 is current working to get everything switched up so it also works for Sprint (mostly appears to be the apk files and XML files) that are specific to the phone. As of now, he has it booting and working fine except there is a large rush of FCs on initial bootup but then everything runs fine.
I wasn't even aware you could make a patch to allow cross-compatibility! XDA never fails to surprise
Just a thought, but maybe they could do it like the SlimROM on multiple devices. He has a common base ROM and another flashable for each device supported. It works out perfectly and multiple ROMs for multiple carriers.
I figure it will be easier than doing it for different devices since I read that all the US variants are essentially the same. Not sure but worth a look.

Will there ever be any SGH-T999V development?
Does anyone think that someone with a SGH-T999V Wind Mobile variant will ever be able to root their phone so they can overclock the cpu, etc?
Why not? I am using a custom rom and overclocked to 1890 at the moment.
Just use the windows way to root. I knbow it works
I have not tried the toolkit.
If you are going to flash a custom rom just make sure it does not contain the boot, modem and amss file in the rom that you are flashing.

What about using i9300 themes and mods? Will this cause constant FCs or other issues?

I am curious of this too. I have the wind mobile galaxy s 3 and I was hoping to put cyanogenmod on it. Is this possible? Let me know, any help would be appreciated.

I'm more curious as to what exactly the differences are between the 2 variants (i.e. t999 vs t999v). What could possibly make them so different from each other that ROMs from tmobile wouldn't work on wind GS3?
What if you accidentally tried to flash i9300 rom and your phone is not turning on.
With the forums changed I accidentally flashed the wrong version rom on my phone. :crying:

Thanks for the link, unfortunately the phone will not go into download mode for odin, it won't even turn on.
After doing some research it looks like I have to fix it through jtag.
I think I could do it, but you need some expensive jtag box that connects to the computer(It's called the Riff Box), but it would be cheaper if I just sent my phone into here it costs $60. Not ideal, but not a complete disaster either. Unless there is some other way to JTAG I am out of options.

Is there any skilled developers that can port the pre-release 4.2 rom released by Samsung for the S3 I9300 so it can be flashed on to my Telus I747M S3.

You don't want to flash a international version of the firmware to your canadian S3.. That will brick it.
Also, if you searched a little, you'd know that we have 4.2.2 ROMs all over here. Please take a couple hours and go read the stickies.

Ok and when I bought my phone I did try flashing the other i9300 rom, but it only soft bricked the phone. I easily unbricked it by flashing the stock rom. It's just that I noticed that some developers ported some roms from sprint to AT&T. What I really wanted was multi-window. But thanks anyways.

Should've been clearer with your question. Either way, don't flash a I9300 ROM
As for multi-window, some ROMs offer that feature but you'll have to search for them as I don't use it myself. Sorry I can't be of more help.
Good luck!

Its easier to go to and from AT&T, Verizon, Sprint and T-Mobile because of the similar hardware. I'd you need a port its pretty simple.
Unfortunately the international ROM has different hardware (quad core CPU, 1gb ram) which makes it very difficult to port over to our ROMs. Most devs don't even bother.

Oh I see now, thanks for the info.
I am trying to understand that porting process as well. Could you not flash a bootloader and a kernel to make the i9300 rom launch on the i747? Sorry I was just wanting a touchwiz rom that was later than 4.1.1 for the i747. Sorry I am sure this is a ridiculous question but I just want to understand the portion of this that makes it so difficult. Thank you.

You can indeed use either of these. Your model (747m) is identical to the ATT model(747) Any ROM that works on the ATT model will be compatible. One thing worth noting is that there is no longer update support for the De-tmobilized ROM.

thnaks for your answer..
Im new to this part of XDA, I just recently purchased a Galaxy S3 T999L.
Purchasing this phone, I had no idea there was a non LTE Model which leads me in a bit of confusion when looking for a custom Rom
Im no rookie when it comes to flashing. If you look Below in my sig you can see the devices I currently have and have flashed different roms many times in the past. My question is what ROMs will work with my T999L? Ive looked and to my confusion have seen more for the T999 than anything since its been around much longer.. I've been looking and the forum here is a bit fragmented and its hard to see which ROM will go to which device. Please forgive me for my ignorance, Im just trying to play catch up, and perhaps contribute in the future in some way.
Edit: Im more familiar with flashing Tablets than phones, I dont have much experience with flashing radios and other phone related stuff...Is there a Difference with T999 and T999L other than the Radio?
edit 2: No comments? I guess either i said the wrong thing, or I posted in the wrong forum..
Thank you in advance
The t-999 ROMs will work with your t-999l, except the 4.3 touchwiz ROMs for the moment. 4.3 aosp/cm/aokp is fine.. There's really not much difference between the two, except the t-999l was updated to support lte.. Do not flash a t-999 modem to your t-999l, it won't brick but it won't pick up service at all. I suggest looking at the t-999l and t-999n q&a thread for further info

I did just that.... And u didn't have to be rude about it..
Thanks for your input
Don't mean to hi-jack this thread but it kind of pertains the the question. I have the T999L as well. I've read Doc's informational thread about the T999L and T999N.
In terms of this part:
"ONLY flash T999L firmware to a T999L and T999N firmware to a T999N!!!!
If it does not match your model EXACTLY, it will almost certainly brick your device!!!"
I keep reading I can safely flash T999 roms, kernels, etc. But it's the firmware process that confuses me. Should I only stick to 4.1.2 roms (can I even flash Jamison's 4.1.1 rom for example), or can I flash a 4.3 TW rom in the future, assuming the leaked builds get LTE support when the official update comes out?
Thanks in advance.

If that's true then how come the T999L wasn't updated to 4.3 alongside the T999? The 4.1.2 software wasn't even the same. No multi-window, no Note 2 photo gallery, still rockin the old "My Files" app on the T999L 4.1.2 software.....At first I thought it was just the "LTE Radio" difference but I guess there's more to it seeing the differences in software.

Firmware refers to the files used in Odin, so for those, make sure you use the ones for your device only. You can flash any ROM, even 4.1.1 I believe.. And yes once there's a leaked 4.3 firmware for the t999l you should be able to just flash the modem and then flash a 4.3 tw ROM, based on what we experienced with the t999

Thanks a lot for this. Been bugging me for a while now. I'll probably take the plunge soon and use "The Recovery Way." Rooted my first S3 using motochopper back in June or July when I first got it, but problems arose and exchanged it at Costco (just got it and WiFi wouldn't connect after a factory reset). Been scared since lol. Also scared me that I wouldn't receive official updates anymore as it said it was modified, but that doesn't bug me anymore reading all the complaints about the whole no turning back.
Thanks again!
I'm looking into flashing a custom ROM onto my T999L for the first time as well...have any of you guys taken the plunge yet, and have any feedback on specific ROMS? I think I will try with AOKP
Can you flash a d2tmo rom on the i747 d2lte/d2att?
I am not 110% sure, it might be possible.
I figured, should I try porting?

depends on the Rom.......such as

CyanideL is compatible to both.
Not to mention some of the replies on this thread sounds like a bunch of kids, sorry to be rude.
Some ROMS are fine for either phone. You may be able to get a Tmo ROM to work on the ATT s3 if you flash the Tmo ROM and immediately flash a compatible i747 kernel. I do this with my ATT note 3.

Ported ROMs should work, just make sure whatever ROM you want to boot works with the dt2Lte. I am coming from the GS2 and just got a GS4 not long ago, so my knowledge of ROMs on the GS3 here is limited due to the fact that my GS3 is just stock rooted.

infamous last words to a flasher,lol.......That Rom is for the galaxy s3 neo......worst case scenario is you brick and I have bricked a few, its not easy to recover and some have never recovered their device.
VERY first thing you need to do is find out what bootloader,modem,recovery,etc. and find a Rom that meets the criteria of YOUR device. Post your info and I will shoot you a list of compatible Roms that I can verify works.
I hope I helped

being as you are on the latest NJ1 I can tell you from reading forums that you can run almost every 4.4.4 or 5.0.x Rom on the front page of..... http://forum.xda-developers.com/galaxy-s3-att/development
I am on NE4 and have ran every Rom on that page plus a bunch more. I cant tell you which ones I like more because they are all the same base, some have added features, but they are all great in their own way.
