[Q]How to flash other S3 ROMs to the Tmobile S3

Hello, I was curious if you can flash ROMs from the S3's from other carriers besides T-Mobile and also flash ROMs from the international forums. I remeber back when i had my Vibrant all you would have to do is flash the correct boot.img and also replace the keylayout file. Is it as simple as flashing a tmobile boot.img since the keys are all the same? Thank you in advance.

don't do it.

There is a possibility of sharing ROMs with the AT&T model. If you go check out their forum, there are a couple of ROMs which people have successfully flashed on the T-Mobile model. Search the threads and flash at your own risk!

That is totally true. On the Hercules you could flash the skyrocket roms. But the T-Mobile ones are usually better. The att ones are really only better when att leaks first.
Don't do it was an oversimplification, however.
Just heard about too many people flashing the international roms.

Nope, the hardware internally is too different. I doubt there'll be an easy method to port the ROMs either.
The AT&T ROMs on the other hand should be fairly easy to port and I think there is a group working towards this goal.

You will lose your insurance.
Just to let you know, you will lose your phone's insurance, this is not the same as the 90 day warranty. I remember I had flashed my vibrant to a rom using the international model, about six months later I got a letter in the mail saying assurion would no longer insure my phone, because it wasn't the right model. I might have been able to add the text file that adds the correct model number, but I don't know if that really works or how to I it.

In this case they could have seen the flashing being done and the changing of the build.prop file. That would make the most sense to me.

You obviously haven't been reading...heck go for it.
You CAN NOT do other roms, as was stated, the hardware is different.

Not that hard to search. Do it and report back with results.

AT&T ROMs and even Sprint ROMs work just fine if you configure APN settings.

why? why would anyone need to flash a ROM from a completely different carrier?

Apparently Sprint's do, but Verizon's a no-go right now because they have some additional SIM verification.

Risky is an i9300 rom because the SoC is 100% different. We all have the same SoC so it's not as big of a deal.

Hey,
How do you configure the apn settings? I'm on an att rom and love it, on wifi it is fine but when it says 4g away from wifi no luck with service. I can get edge, but that is it.

Ok I figured it out but I cant get the att apn to stick does the phone have to be unlocked?

International N7105 firmware confirmed working on i317!!!

For any of you who want to have your cake and eat it too, you can now flash the international N7105 firmware onto your AT&T branded i317!
What does this mean? It means that you can give AT&T the middle finger by having unlocked firmware with none of the restrictions and bloatware. By extension, this also means that you can benefit from the development going on for the international devices.
Finally, this also means that you can reap all those benefits without sacrificing LTE access in North America!
Now that this has been confirmed to work with the i317, I wonder if the T889 is next...
Check out the main thread over here.

This is nothing new.
Well known information.

We tried flashing the international N7105 firmware onto the i317 using Odin, but that didn't work. However, the procedure seems to be working if, instead of using Odin, you flash a re-packaged stock N7105 firmware using a custom recovery like CWM or TWRP, just like flashing any other custom ROM. Once that's done, just flash the AT&T modem/kernel, and you're all set!
Unfortunately, there hasn't been much development for the N7105 yet. Root, CWM, deodexing and all the other basics are there, but that's all for the moment. Devs are still trying to work out N7100/N7105 inter-compatibility. N7100 firmware will flash to an N7105, but the modem won't work, so that's pretty useless, and that's what we're all trying to fix.
At least, in the mean time, you can enjoy a stock N7105 experience in North America without AT&T/Rogers sticking their fingers in the pie

Is the 7100 the non LTE version and 7105 LTE? If this allows us to get FM Radio on our North American Note 2s, I'm going to be very happy!

Very nice.
Upon thinking about it. I believe there is a way to use this method to give us international firmware and also retain our NA CSC's so we keep carrier specific settings such as Wi-Fi access, Fast dormancy and the like too.
Currently working on it and will get back to people once I am finished.
Glad to see someone else was working on this as it was something I wanted to get around to messing with but have been busy poking into Bootloaders and dialer codes.

Agreed however, no one knows for sure it isn't present in our devices and that Samsung just removed the driver at the request of the greedy NA companies. They don't want us listening to something for free when they can force us to connect and use data. Maybe the driver is in the 7105 firmware...

My phone is rooted, what is so good/different about the international version?

Did what Miscom had done and got the latest GT-I7105 Unbranded firmware release LJ5, with this one I injected the Canadian CSC's and everything seems to be working except a few carrier apps that check for the proper model number they would force close on me.
Going over this firmware, seems okay but doesn't seem to be any better then the stock LJ2 that came with the phone.
My main hope with using an international firmware would be unlocked dialer codes, and I was correct in my testing, any carrier locked dialer codes are controller within the firmware + check what CSC you have as well.
Got some working that I couldn't before hand, however the main one that I wanted to use was the *#7465625# to view network lock status, it was one that I couldn't get working, but I believe that it wasn't working because my phone is already a factory unlocked one so to really know for sure I'd half to have one that is known to be locked.
Anyways, glad this experiment worked, I will definitely be looking at this again in the future, however I know that the Samsung Canada is planning on releasing an updated firmware for the phone at the same time or soon after the Canadian S3's get their Jelly Bean updated, and it is also rumored that they will be 4.1.2 as well. So with this possibility I will be going back to Bell's Stock firmware and see what we get in a few weeks.

Not recommended. You still have the T-Mobile phone so all roms etc. should still be for T-Mobile.
The only thing that you might wanna do different, and one of you more knowledgeable people correct me if im wrong, is to flash a different radio so you can get better signal.
I go to Canada a lot and interchange often between T-Mobile and bell without much issue.

Can you use a Kernel for i9505 or I337 on M919?

Good day to all,
I am just checking to see the full flexibility of the S4 in terms of development.
I'm looking over the specs on all of the different variations that are out for the S4.. a little more then called for.. https://en.wikipedia.org/wiki/Samsung_Galaxy_S4
From my point of view.. the GT-I9505, SGH-I337, SGH-M919 are basicly the same.. only huge difference is the i9505 LTE bands compared to the M919 and I337.
I know if i flash the wrong kernel or mod, it can, and most likely would brick the phone..
i'm not smoking crack here.. but is it possible.. is there a way to use a I337 mod/kernel and flash over .. i guess the radio for the m919?

Can you? Maybe. Should you? No. Would it involve flashing the modem in any case? No.

I run at&t rom's and kernels on my S3 all the time. In fact I run nothing but AT&T versions of slim and kt kernel.
I plan on doing the same thing with my S4 once they get their b/l unlocked.

Exactly!
But, i came from the i9300... and it was a no no to run a i9305 on the phone with the hardware issues... but.. are the AT&T and T-Mobile phones the same?? hardware anyways??

T-Mobile and AT&T variants were next to identical on the GS3, i havent looked at specs for the S4, but i would definately NOT flash international S4 stuff to your US S4, no no no no no dont even think about it!

You probably cab but it will probably have bugs. For instance. On my s3 I can flash kernels from any other carriers and if I do sprint I get rotarion issues.
Sent from my SGH-T999 using Tapatalk 4 Beta

You can flash the ROMs for other models no problem as long as you flash a kernel made specifically for your device. I haven't experimented with kernels for other devices, but I can say that I have made the mistake of flashing both AT&T ROMs and i9505 ROMs and forgot to flash a TMO kernel and all I got was a nice failure to boot after the initial Galaxy S4 splash screen. Can't speak for the other carriers, but I just make it a point to flash KT kernel for the TMO device with each ROM I flash given the problems I've encountered with AT&T and i9505's models.

A brick waiting to happen. You should never flash a kernel that is NOT made for your device. Oh well going to be a good thread to watch a few days. Makes for some good reading, and good lessons for others.
Carry on!
Your welcome

As @lordcheeto03 stated I flashed i9505 rom on ATT and forgot to flash kernel and booted, it displayed a notice on boot that Non-AT&T software is detected, and didn't boot...
I also tested to flash i9505 Modem on i337 and it/ i.e. odin displayed notice, of a failure due to knox [sic] rejecting it...
I booted into recovery manually flashed i337 kernel and it successfully booted without any brick.

[Q] Can We Flash At&t Roms?

Like The Heading Can We Flash At&t Roms because we flash slimbean From At&t And I Have Read That Both types of phones are alike?

I never had to flash ROMs from other carrier coz we have all the best roms here... But u can flash ROMs from at&t as long as u flash a tmobile kernel rite after u flash ur ROM.....

Just thought I'd add a quick statement to that. Yes you can flash AT&T roms to our T999. But unless you consider yourself experienced with the S3 model T999, I would just stick with what we already have here. You can't just flash and have them work 100%. Often there are different tweaks or changes that need to be made.

But at least with the Dandroid ROM, built on S3Rx, you can flash the AT&T Stock MG2 kernel.

Yup, AT&T kernels are compatible with our T999. In fact, some of the custom ones are AT&T kernels just ported over here. At least they were at one time. Haven't looked in a while.

Hey doc Glad to see that you are still here.
I have flash several roms from att out of the box working. Like you said att kernels are compatible. Sprint, verizon roms have to do some tweaking as for to get data working etc but it still fun to do with.
Been a while since I really did something but slowly doing stuff when the time is right.
