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!

If a solution for this is found I'll definitely be buying a red GS3 soon.

I seriously wouldnt count on it. The two networks run on different technologies. Im pretty sure the hw is different due to this.

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.

T-Mobile doesn't have 4G. The iPhone will get HSPA.

Rom Flashing Problem SGH-T999

Hello everyone at XDA.
Recently I bought a T-Mobile Samsung Galaxy S3 T-999 (Base Model T999UVALEM ). Howerver I am curious if this phone can be patch with Mobilicity "Canada Carrier" Stock Rom (T999VVLALE6 )?

I wouldn't, I've heard mixing the Canadian and T-mobile ROMs is a one-way ticket to brick. Stick to ROMs designed specifically for the SGH-T999 (T-Mobile version).

We could port it. Why do you want that rom?

Don't mention it. I was so stupid and didn't look around before purchasing this phone.
I am a Canadian Mobilicity user, I usually buy T-Mobile phone, but this time i didn't realize Mobilicity carry GS3. With T-Mobile custom Rom there alot of junk apps. Such as T-Mobile Hot-Spot, Access T-Mobile else. Since I saw SGH-T999 and SGH-T999v are the same spec just wonder if I can load Mobilicity Rom to my T-Mobile GS3 phone. So that i can use their custom apps

You can jut copy their apps to /system/app/ and they should work.

That's what it appears he is saying.
Sent from my SGH-T999 using xda premium

Wouldn't be too surprising really. Aside from slightly different radios, aren't all the US variants (canadian too) virtually identical hardware-wise? It would stand to reason that they would carry the same partition layouts as well.
Though I wouldn't go flashing away without verification of that!
Sent from my SGH-T999 using xda app-developers app

My thoughts at least, I flashed a few at&t roms with no issues besides build.prop stuff. I'm with you on not flashing things though lol.
Sent from my SGH-T999 using xda premium

Yes the baseband stayd the same .I was pretty excited been using it for a week.battery life is good screen is on top of the list then system.so far beside using hiapn for apn settings it has been really stable one or two reeboots that I can remember from restoring youtube a delete and market install fixed that.

How did you bypass the verizon network verification?or did it not say registering on the verizon network? I have flashed many Att, Sprint, and verizon roms, but most(if not all) of the verizon roms have a built in verifyer for their specific network.

[Q] ROM Question

I have a quick question regarding which ROMs are available to me. I'm using a T-Mobile Galaxy Note 2 but there is very little development in that area (less that ten threads). I'd like to know if other GSM ROMs are flushable on the SGH-T889 (T-Mobile) device. I know that this has been the case with other devices in the past. Please advise. Thanks.
Sent from my SGH-T889 using xda premium

No, they are not suited for your device. Only for GT-N7100 HSPA+ version in this forum, not for LTE or Dual Core devices.

The T-Mobile version is HSPA+ and it's quad-core, not dual-core. It is technically LTE capable but it isn't used. It is basically the same as the international version.

[Q] 4G LTE compatibility?

I just saw in Miami that we're getting 4G LTE today and want to know if it's compatible with the T989 s2?

No. We don't have the right hardware needed.

Unless Tmo planned for 1.5 years ahead when they launched the Herc, I doubt we have the right hardware. Hopefully it does have support and Tmo did plan for the future but they're keeping it a secret . Because when they build the source for a ROM, they don't take out individual little things for certain devices.

Don't get your hopes up. I think the S3 and Note 2 are the only ones that are capable at the moment and they will need a software upgrade to unlock it.

Because firmwares are made by Samsung and the skyrocket has lte. The firmwares are designed for simplicity. Meaning, Samsung only has to make one firmware for all variants. That's why that option is there.

Actually the T-Mobile Samsung Galaxy S III (SGH-T999) is NOT capable of it period. I have one. But i did read rumors that they may be making another S3, one with the exact same specs, but adding an LTE capable chip. T-Mobile went on the cheap side with their S3 and used the same chip as the ATT and other variants, but cut out the LTE capabilities. Kinda dumb but hey im not the CEO. lol.
But you are right, the Note 2 just needs a firmware update to enable LTE, also, the only other phone capable of T-Mobile LTE is the Windows Phone 8X.

Yeah I feel you.. it is bull. But then again neither sprint nor Verizon have existing contracts holders an lte device when they rolled it out. Guess that's just how it goes.
