At&t galaxy s3 to T-Mobile help

I got my unlocked s3 so I can use it on T-Mobile and hate edge so I was wondering if flashing the blaze modem would allow me to get 4g like the at&t galaxy note did.

Blaze is a .gs2, it would probably brick. I wouldn't risk it. If anything I'd try the t-mobile .gs3 radio.

I need to know if someone has done this and gotten it to work the tmo gs3 modem if the blaze doesnt

I been thinking...instead of messing with all that and end up with a brick, why just not sell it on ebay and buy an actual Tmobile one or maybe trade with someone willing to. I would look at the selling price for an AT&T GS3 on ebay and how much would a Tmobile run and if it's not that much difference then pay the difference than end up with a possible brick. Plus I have read some forums where if you flash some things that are not meant for your phone you can even mess up the IME on your phone with no way to flash it back at the moment until someone comes up with a solution for it.

Not trying to be a jerk. Just a friendly reminder that this is not development related and needs to be in general or QA. I would repost there and report your thread to a moderator before the pitch forks come out.

When I put my friends note to t mobile it was the modem you had to flash , if your set on doing it , read a bunch on ways to do the note WITHOUT a custom Rom then find the same files you use in that ( the modem and if I remember right there was one other thing ) then go to the t mobile section in the sgs 3 thread and ask for help finding those files , but do a lot of reading first cause it would be a shame to brick your awesome phone

buy the t-mobile version. it doesn't work hardware not supported

im looking into this as well, i had the att note and flashed the tmobile modem worked like a charm so now im looking to do same with s3. if i find anything ill let you know

I don't thonk it will work at all. Att's S3 is LTE, correct. Tmobiles is not. Two different hw radios used.
If you do try it please post your results for others!

I seriously wouldnt count on it. The two networks run on different technologies. Im pretty sure the hw is different due to this.
Sent from my SGH-T999 using xda app-developers app

Have you guys tried the radios in the dev section by wildchld? I'm not sure it will work either but maybe worth a try. It has a script that backs up current radio and you can revert back. Atleast on T-Mobile s3 it does. Just need to reflash the restore zip to go back to previous radio. Again try at your own risk. There's a huge chance you can brick your device.

I don't think it matters if the Gs3 from T-Mobile doesn't have LTE, I used to have my Galaxy s2 skyrocket with LTE running on T-Mobile 3G/4G off a GS2 Hercules Modem.

Then by all means, give it a shot. I have no problem being proven wrong on stuff like this!
Just remember that was a different phone. And tmobiles radio Im pretty sure was confirmed to NOT support LTE. So they are different.
I'm definately looking forward to hearing someones results after trying! Just do some research on the two radios, and make sure the sw modem is on the same partition for each phone. (I think it will be. But if its not you could end up with serious problems)
Good luck to whomever tries it!

Probably won't, the T-Mobile phone is pentaband so it will run 3/4G on AT&T, but their version isn't. Try it though.

GS3 Tmobile LTE capable?

So I was in a tmobile store today and was told that both the note II and Gs3 will receive a software patch to enable the lte radio. Asked the question like 10 different ways as I've read online that the gs3 will NOT be let cab able.
the internal phone workings are a little above my head...but i was told that the tmobile sg3 is the same as say the att model which does have the lte radio,
So, does that sound right that the SG3 is future proof and will be able to enable LTE?

The question I should have asked is if they are shipping different GS3's for tmobile now? But regardless they were so confident that it will (LTE) be enabled...wanted to ask the experts thx

and that was from day 1? Obviously there has been debate about this on this forum and people much smarter than I have agued that it will never get LTE...
do you remember if there is something that has to be enabled? Or if say where I live they activate the LTE tower, boom it will work?

Its been a while so I dont remember the details, but I am convinced that
1. We will NOTget LTE one our GS3.
2. It doesn't really matter. By the time the majority of us get LTE in our market, we will have moved on to an even better phone! Also, most of us will get hspa+42 soon which for now is more than sufficient for almost everyones needs.

I think these threads need to be shut down. There are a number of other threads exactly like this that holds the correct information. Thanks Doc

I agree with Doc, we'll probably be on better phones by the time we have decent LTE reception -- and I'm happy enough with the DC-HSPA+ modem.
IMHO, they will likely release a Galaxy S3 [4G] LTE as an interm between the S3 and the S4. WRT LTE, all I know is what I see on Wikipedia's snapdragon article. Which isn't very clear on details. Also numerous MSM8960 phones /w LTE exist but do we even know if it's on die, let along bothering to crack open an AT&T and T-Mobile GS3 for a little hardware compare?

So afye reading this I have a question.... if you guys are saying that our phones arent capable then why on my phone (running frosty jb v7) are there 2 system apps called LTESettings.apk and LTETest.apk??? Are these not for our phone and are just ther e due to it being a port? And if so can I safely remove them so they are taking away ram and battery? Thanks in advanced

They serve no purpose to our devices so yes you can remove them. Just in case, make a backup first. Like move them to memory card or something.

Samsung would only fail if they didn't include lte hardware in the new galaxy s4 especially because it's being released after tmobile starts rolling out lte which is February 2013

Maybe I am the only one. LTE is not very efficient. I am happy with 3g+++.Tmo 3g super sized is a very good system. My company provided LTE hot spot sucks bandwidth like no other. Be careful what you ask for.

T-Mobile will launch refreshed Galaxy S III with LTE support

Source: http://www.theverge.com/2013/1/8/38...aunch-refreshed-galaxy-s-iii-with-lte-support
At a CES briefing today, T-Mobile CTO Neville Ray revealed to The Verge that the company will launch a refreshed version of Samsung's wildly popular Galaxy S III that features support for its upcoming LTE network — a network that has now been confirmed to launch commercially any week now. It's not yet known whether the phone will be marketed as a new, distinct model or as a silent and unadvertised swap on store shelves.
Though the Galaxy S III that's presently being offered by T-Mobile does not support LTE, the slightly newer Galaxy Note II does; Ray tells us that it'll require a "small" software update to enable it once it's available. No other LTE-capable phones have been announced by T-Mobile yet, but it's likely that we'll see some announcements as the first markets go live across the first and second quarter of the year.

What are the chances that this is really just the T999? If its really a brand new model (T999LTE / T1000 / T:silly::silly::silly, how many of you would sell your current T999 and upgrade?

T999L - We've been hearing bits and pieces about it (Mostly speculation) for a little while now. Nice to have some confirmation though.
Edit: And if the LTE happens to cover my area, you can bet that I'll sell my T999 and get a T999L

for what? lte consumes more power and isnt any faster than what youre already using. in fact, some would argue it is slower...

...and the Vibrant story repeats itself. T-mobile sure loves doing this. At least my unlocked T999 is ready to switch when I get the money to do so.

But seriously, that's why I said "If it happens to cover my area". I know it likely wont, but hey, who knows. I can already almost throw a rock and hit an HSPA+ 42 coverage area.

This is exactly what turns me off about the galaxy line in the US. I thought maybe they'd change with all the carriers having similar phones now, but no. Ill keep my s3 until its paid off then I'm probably going tontrybsomething else.

I dont think its that simple, I believe you need the hardware as well as the modem firmware, just flashing the modem could potentially brick your phone.

I get like 1.6 megs down already. It's more than fast enough.

I think I'm good.
Sent from my SGH-T999 using Tapatalk 2

I'm good with mine. I get almost 20 megs in the dallas metro plex. Tmobile could had the lte turned off like the note 2 and they turn it on when it was available. But they decided to make more money with a new release like the vibrant.

Sent from a galaxy far away!

I guess once this phone is released, there needs to be a detailed teardown (anandtech / ifixit) that compares the old T999 with the new T999L.
Hopefully there are no hardware differences, and everything is firmware/rom related.
If there are hardware differences, maybe we can start frankensteining a broken T999L (i.e. cracked screens etc) with a working T999 LOL

Noob question

I have a really quick and easy question. Im planning to buy an at&t gs3 phone from craiglist but im planning to use it on a different carrier, gosmart, what are the things I have to look for? Im sorry this sounds very elemental but I have always used sprint and I really dont know much about sim card.

At&t phones operate on gsm. Make sure gosmart is a gsm carrier. Also, depending on the carrier, you may not see LTE speeds

Well i assume you would have to unlock it which is now illegal without carrier permission so you would have to call at&t and have them unlock if it doesn't already come unlocked

Gosmart uses a sim card( tmobile) but im not worried about lte speeds. What im worried is at&t claiming back their phone. Now this guya in craiglist says he bought the gs3 and then his job gave him the iphone, so he has no use for it. Will at&t will automatically unlock it when he got the iphone?

Flash for Verizon?

I'm sorry if this is in the forum somewhere but I couldn't fine it. Is there a way to flash a LS970 to verizon? Not 4g since I am not going to solder on a sim tray but for just 3g service?

You might be able to get it to work on page plus but certainly not Verizon without doing something illegal I think. Search around, I'm sure you'll find your answer

I'm guessing you can ESN Swap, Or "ESN Clone" with an active Verizon phone. But Verizon LTE operates on the 700mhz Spectrum, This phone is programmed only for 1900mhz LTE.

I dont care about verizon or page plus or who ever...
I just would like to learn how so when and if the time comes i put this to rest i can flash it to something else and dump it off....
