Hey guys...Im doing a favor for a friend...he just got the I777 rooted ...but he wants to use it for Tmobile...what do i need to change for it to work with a custom rom...and then again can i port a rom from the tmobile S2 ...just modem?any input would be appreciated..
Edit:i have the E4GT on sprint...so i'm not really familiar with the gsm models...
While I should say use the search bar, all the information I've found is pretty outdated regarding this.
The simple answer is that you probably can't get it to work, at least not 3G/4G, if Edge is fine then you can unlock the phone with "Galaxy S Unlock" in the play store, just follow the directions listed, it's pretty simple.
The extended answer:
You might be able to depending on where you are. T-Mobile generally uses the 1700 MHz and 2100 MHz bands for 3G/4G, but the i777 doesn't use the 1700 MHz bands, instead it can use either 850, 1900, 2100 MHz bands for 3G/4G. However in preparation for LTE and just to increase bandwidth across 3G/4G they are starting to take some of their 1900 MHz spectrum from their edge networks and move it to 3G/4G/LTE. This has just started happening very recently and is currently in very few markets, however you may be in one of those, it is still expanding if you aren't but it may take a while. The only way you could know is if you took a T-Mobile sim card and put it in an unlocked i777 and if you get 3G/4G then you are good, otherwise you are stuck with Edge.

The S2 for ATT doesn't support 3g for T mobile and vice versa. There could be some weird instance as mentioned above where it could work but in most cases it won't.
Thank you very much for the update guys... I'll see what I can do...

Mostly true, T-Mobile's S2 should work with AT&T's network, you may have to flash a new radio but theoretically it should work.
You cannot port a T-Mobile ROM because T-Mobile does not have a similar gs2. The T-Mobile gs2 is the twin brother to the skyrocket

I have i777 working on tmobile with 4g. My wife has tmobile so when I upgraded to the GS3, I unlocked the phone using the code from AT&T and I get "4g" on T-Mobile. I did a speed test and was able to get good speeds.

Sorry for the late response, I haven't been on here much lately.I live out in Little Elm, slightly past Frisco close to Lewisville Lake and 380/University. I am about to upgrade my phone again and give my wife the GS3. haven't decided between the GS4 and Note 2 yet.
I am in So.Cal and got 4G out of Edge half of the time from Tmobile ofcourse. The speed is around 7-10Mb/s or so
is there a rom ported from att to T-mobile

If I purchase the sgs2 from Europe I know it should work with at&t and T-Mobile here in the USA. My question is will 3g or hspa + work or just 2g
The Herb Frees Your Mind
It's said to have AT&T's 3G, but that it should work with any other carrier, which pretty much means AT&T 3G(and HSPA+), T-Mobile 2G.

Check the bands. Google it. If they're the same then it will work. AT&T's 4G network will work with European and Canada's will also I believe.

that's the problem, I am new to this stuff and willing to learn. Let's start with what BAND is, and how do I check that BAND.
I am not 100% sure. But I believe that it well not work on T-Mobile USA 4G network. It uses different frequencies. If the SGS II ever comes out on Rogers then it will work on T-Mobile USA.

You are right. And once the merger goes through the T-Mobile 3 and 4g phones wont work on 3 or 4g. This was already stated by att and tmobile

By that time the Galaxy S III will come out lol. But I will definitely love the HSPA+ speeds on my SGS II.
If you really want it either:
1) Switch to AT&T, you will get 4G speeds
2) Wait for the Samsung Hercules to come out on T-Mobile (Should be this or next month)
In the end, all people who buy T-Mobile phones now will eventually suffer later on. ;D

Dude,
It works very well! I have the AT&T Note... I unlocked it ($25 on ebay, I prefer this method as the seller has a reputation to protect). I then had it rooted, then flashed over to T-Mobile (http://rootgalaxynote.com/).
I did a test on the $30 - 1,500 minute plan (only 30 megs of data) to see how it works. I did this before flashing the modem and the 2G/Edge doesn't work well at all for the Note. However, after flashing the modem, it screams on TMO's 4G.
Good luck to you, but flash it and don't look back!

But just as a heads up, the exynos chip in the international version is not LTE equipped. So, if you get the international model it won't work on Tmobile's 4g bands even if you flash/hack/pray to the cell gods or anything else to your phone.

I'm not totally sure but, I believe if you get the international it will work on tmobile's hspa+. You shouldn't have to get the AT&T version if you just want to use the phone on tmobile and, are ok without LTE. Hspa+ is still very fast.

T-Mobile doesn't even have LTE so it doesn't make a difference.
The AT&T Note is the only one that works with T-Mobile 4G which again, is not LTE.
Also, no the international version does NOT get T-Mobile hspa +.
The international version ONLY gets EDGE on T-Mobile.

I don't think the radio from the ATT LGOG works with TMO LTE.
Is there anyway to flash another radio that would let u get 3g or 4g something other than Edge.
Sent from my LG-E970 using xda app-developers app
I just ordered this phone today so I can't speak from experience, but T-mobile LTE should work with the right settings. From what I've read the AT&T Optimus G (E970) has support for LTE on frequencies 700mhz and 1700mhz, T-mobile also uses 1700mhz for their LTE. Some areas in the US might let it get HSPA as well. If everything is unlocked and you're using a T-mobile SIM card then you should just need the correct APN settings. This link should help:

Hey - just went through this for an ATT i747 (Samsung Galaxy S3). Someone in the forum provided the Tmobile bootloader, modem and platform and att CSC. It ended up being what T-mobile used to tested their LTE network using ATT i747. Works great get 4G LTE. Figure will need the same type of code for the LG-E970 bootloader, modem, and platform. Still having to use ATT CSC.
On the other forum they offered up a bounty to get it done.
Could do the same thing.
You're the millionth person to ask. No, it won't work. Not going to bother pointing out why anymore. No tmo version of the lgog exists.

I have an unlocked ATT branded i717 that I've been using on T-Mobile here in San Diego for about 2 months now...I'm using the modified T-Mo ICS Blaze radio. Due to the area of San Diego I'm in I am not in a refarmed network area so no LTE for me but my "4G" speeds are usually around 10megs down and 2 megs up at home which I'm pretty satisfied with.
Anyways to answer your question I'd refer to this thread.....

Yes you need to change your modem or else you you will be stuck using roaming on the 2G frequencies. I recommend the Blaze 4G UVMB1 modem on this page:

Of all the modems I have used, this one seems to be the best one. If something else works better let me know so I can try it for myself.

Its funny that I didn't need to change anything, all I did was, get the $30 dollar plan from wal mart, I call T-Mobile to help me out with activation and new number. And they ask me for my imei and that's it. My LTE runs right when it activated, everything is pure stock!

Refarmed are means tmobile is using same frequencies and towers as at&t, so the stock modem will work fine. Just input APN settings and go!
