Speeds could be better, and the signal indicator doesn't change from 3G to H+, but these are definitely at least HSPA speeds on the 1700MHz AWS band

After flashing the 4 files in Odin, the data only showed E on the touchwiz "lte test" ROM, I then flashed a t999 twrp via Odin and then flashed a t999 ROM, now I'm here.

i have done it and have cwm recovery on stock rooted 4.0.4 roma and while its only hspa+ in oklahoma city cause theres no tmo lte here yet i get 5-13mbps down and 1-3up so id say yes it works very well. rooting doesnt affect anything however installing another rom im not gonna try cause i dont wanna loose the 1700mhz as ive heard nothing to that result yet.

And FYI i Did this to 3 other I747's for friends with the same result.

Not to be so damn picky....BUT....now that we've got that settled....at least the 747 guys....any way to give 1900 preference over 1700? When I leave my office I'm pretty much always in a 1900 area buy stay on the 1700 band because I never lose the 1700 signal. (I pick it up when I go into the office and lose 1900). Any ideas? Other than toggling airplane mode after leaving the office???

Dude if you can do that a nice prize is waiting for you.....
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] tmokeith:
I cant speak for all markets, but where I am 1700 has preference because there is more capacity there. It’s a set in the RNC and not much you can do from your phone. It should be faster on 1700. In my market 1900 is only 24Mbps and 1700 is 42Mbps.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] HumanXv2:

About the same in Fort Worth, but there are areas where 1700MHz has coverage where 1900 does not.

I tried to just flash a stock rooted ATT 4.1.1 over the top of what I had working from Keith.. It loaded fine but I lost my 1700mhz and my *#2263# controls no longer functioned.

After this I went back and flashed all 4 files again except I replaced the PLATFORM file with the same exact stock rooted ATT 4.1.1 ROM. This actually worked perfectly and I have 1700mhz again, I'm rooted on stock ATT 4.1.1 and not stuck on 4.0.4.

I did previously try this with a TMO T999 stock rooted ROM and it was a no go that failed in ODIN.

So I'm assuming any legit stock/custom ATT i747 ROM can be flashed an retain 1700mhz as long as you use the other 3 files Keith provided..However ymmv..
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] ysr84:

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] fmllc:
Youre making it way too complicated...just flash the 4 files....then a recovery for T999....then you can download ANY rom in the T999 forum and flash through recovery.....ive done it on 3 phones now 2 running liquid smooth and one running wicked

---------- Post added at 08:06 AM ---------- Previous post was at 07:50 AM ----------

Fyi wicked rom has an option through its aroma installer to install the rom as a T999 or an I747. Choosing the later will set all build prop data to an 747 and you will still maintain use of 1700 band
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] HumanXv2:

Not a dum questions but I am placing it in the right spot ;).... I have tried to flash CWM modems (At&t based), you can flash them but they would give you a null imei and no reception....

For the Note 2 (which has a Qualcomm modem, like the US S3's), the way it was done was by taking a QCN backup from a T889 (T-Mobile Note 2), stripping out the IMEI from that backup, and then flashing it to an i317 (AT&T Note 2). That enabled AWS (1700 MHz) HSPA+ perfectly.

Has anyone tried that?

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] milan03:
There is no hardware support for 1700/2100Mhz AWS band 4 for WCDMA on AT&T's Samsung Galaxy SIII.

The phone can't magically start working on T-Mobile's AWS by flashing the rom/firmware as there isn't a single antenna, filter, amplifier tuned to 1700/2100Mhz on the WCDMA portion of that phone. LTE has 2x2 MIMO support for Band 4, but that ain't gonna work for WCDMA.

It's as simple as that.

I have tried to put the sim card in the ROGERS SGS3 and it shows the wind mobile Access points however does not register....Is that something good or bad???
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] TLS2000:
How sure are you about that? The Rogers S3 supports the AWS spectrum for LTE since that's what Rogers uses for LTE.

Every indication shows that the Rogers and at&t S3s are the same phone hardware wise.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] milan03:
Sure, but neither one of them support AWS on WCDMA. The MIMO antenna setup, and the rest of the LTE hardware is useless for HSPA network access on that same band.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] TLS2000:
Again, how sure are you that the phone doesn't have the hardware to support AWS on WCDMA? Are you saying so because you have intimate knowledge of the hardware or are you just saying that because that's what you think?

The Skyrocket supported it if you just changed out the modem file.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] milan03:
Yes I do. Look at the FCC report.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] george241312:
This has to be possible just unlocked my s3 from tmobile popped in an at&t sim card and got hspa+ .,.......
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] milan03:
T-Mobile's version has support for both AT&T WCDMA bands. Unfortunately not the other way around.

As I said, read FCC filings for both phones if you don't feel like listening to me.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SwervFusion:
Because the Tmo version has all of the bands except for LTE. The AT&T version is the one missing the 1700 band.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] george241312:
Is at&t network so slow that they need an lte chip in the device to reach 20 megabits and more?? Wow I easily get more than 20 megabits per second on tmobile hspa+
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] SwervFusion:
Its off topic so I won't get into the argument, but it depends on where you live. I have an active Tmo and at&t sim and I'm done with tmo for good reason.

If this is possible shouldn't it be possible to get the Korean Quad-Core LTE model working on ATT?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] milan03:
As far as I know, Korean market is using LTE on 800Mhz and 1800Mhz, so korean SGS3 will only work on AT&T's WCDMA. At that point, I'd just get international Exynos version available today.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Product F(RED):
I'm on ST AT&T. I used to be able pull up to 5 down, but they've been throttling me to 256 kbps because AT&T doesn't let them sell SIM cards anymore. So basically in exchange for being allowed to continue using AT&T, I get throttled like hell. I wanna switch to T-Mobile's $30 plan, but their coverage is spotty as hell here. My campus is half EDGE, and I only get one bar of service in my house. But I know their data is fast as hell. Hopefully it's fixed when they roll out LTE here in NYC.

I was on st att and I ran like hell from them. Tmo has strong data around here in places but their voice coverage blows, but I never talk on my phone at all. I was on net10 for a while and they suck just as bad.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Product F(RED):
Tracfone owns Net10 and Straight Talk, so understandable. They don't even try to hide that they're throttling me: I get 256 kbps down but like 2 Mbps up. I pay $49 after taxes, so I don't wanna pay more than that. I'm considering going with T-Mobile's $30 plan, but I heard that after you use your 100 minutes, you can't make or receive calls. Like you can't just pay by the minute. I'm considering Solavei's $49 unlimited talk and text and 4GB plan (with LTE). But like I said lack of good data signal is an issue.

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] Product F(RED):
Dude, T-Mobile's latest CEO is friggin awesome. He straight out called the other carriers bullsh!ters. The reason their coverage is lacking is because they use higher frequencies. AT&T uses 850/1900 MHz. T-Mobile is 1700/1900/2100 MHz. That's why they don't penetrate as well. Their LTE will probably have half the reach of AT&T's and Verizon's too. They just need to double up on towers and repeaters to compensate.

Actually for whatever reason, Sprint and T-Mobile in my house only get a few bars. Although testing with my N2 just now with an unactivated T-Mobile SIM, I pulled like 1-4 out of 5 bars depending on where I was. So they improved or my phone just gets much better signal. Sprint on the other hand is like 1 bar in my house, but as soon as you walk out, you get full service.

Verizon and AT&T get 5/5 bars in my house with LTE and everything. Nothing less.
