Just like the headers says,
I unlocked my tmobile phone a few days ago, I had to downgrade from 4.1.2 to 4.1.1 in order to do so. Problem is that although it shows att on my lock screen, when i try to upgrade back to 4.1.2 it tries to go to tmobile's servers instead of going to att and upgrading to their software. I also get an invalid sim error when i turn on wifi calling and i have no 4GLTE....just 4G. I setup and saved a couple of APN's but it still tries to upgrade from tmobile. Texting and MMS work good and i have tried all of the standard settings on the phone with no luck as well. Am i correct in guessing that it is not the hardware but instead is the software trying to phone back to tmobile. I want a simple factory image from att,BUT my phone is an 889 and i am not sure what image to flash to it. It is also at the moment rooted but if it unroots after the flash i will just re-root it afterwards.
What i am hoping for is that if i get att's software on it ,it will upgrade from att.
Thanks.
Sounds of your trying to upgrade from the phone it self. don't
Dude just flash a stock Rom, clean Rom is what most use. You'll find it in the development section. That way you don't have all the bloat that AT&T adds in the firmware.. JUST make sure it has no modem, cuz that you don't want to do!!.
You don't want to flash a AT&T modem on a T-Mobile GN2. Would just give you boot loops..
Your IN the same boat my buddy was in. He has the same phone you do. So I flashed a AT&T custom Rom on his phone after the unlock process. Then after a few days told him to upgrade back to the newest modem from TMO.
As a side note I changed his model in his build prop to a I317. Just too c what would happen. But lo and behold I had his phone next to mine the other day. LTE area, checked mine and his we're both on AT&T LTE network. LTE 14
Oh yeah let me state that I did no AWS bands unlocking thing. Was just kinda amazed that he was getting LTE from att, on a TMO GN2.

So I've read thru many threads on here and found people that seemed to have flashed their tmobile ROM onto their AT&T device in order to get proper 3G+ speeds.
1) Does this actually work?
2) Is it better to flash the other way (if possible, AT&T rom onto Tmobile) in order to get maximum service from both phones? What is the best/better phone to purchase for future LTE future proofing?

I am also on the t-mobile Q&A section looking for answers... the best phone for future proof and LTE is the AT&T version... no doubt... now... I am waiting for an AT&T Stock Rooted WITH MODEM included in the same flash zip before I begin testing myself... I already ordered from ebay a dual sim card adapter for the Note 2, and the Note 2 is already unlocked... so... any news on this would be great...
I just flashed Tmobile Jedi X3 with my att note 2...all working perfectly....the steps I took was just to flash rom and one of our att kernels and youll be fine...didnt have to flash modem....just put my straight talk apn in done....Everything perfect...btw jedi X3 is super fast....:good::highfive:

Sounds like you might be in the same boat as me. Anxious to get a Note II but not sure which network to commit to with it. Your comment about needing to get a TMo ROM to get "proper 3G+ speeds" is disconcerting. It also pushes me a bit towards TMo since it's got the LTE radio promised for future update.
What exactly is wrong with the stock device's 3G+ speeds on AT&T?
Where I live and work (Los Angeles area - San Fernando & Santa Clarita valleys), LTE's not activated, and no firm date when it will come our way. AT&T's HSPA data speeds here aren't anything to write home about, but neither are TMo's when I tested one of their devices in the local shop. My AT&T phone is lucky to get 4Mb/s down, 0.2Mb/s up, and generally only about 2-3Mb/s down. The TMo Galaxy SIII I tested got 4MB/s down. Hard numbers to swallow when I've got an SIII on VZW LTE pulling down 20Mb/s in the same area.

I need clarification on this. Just because the ROM flashed worked, doesn't necessarily mean the proper AWS radio's were activated to attain 4G speeds that are required on T-mobile (this is nothing to do with LTE).
Are you saying that by flashing the tmobile ROM onto your at&t note 2, you are able to attain all connections (not just Edge, but HSPA+ 4G) with your AT&T device to tmobile using AWS? I know Tmobile has begun refarming out to 4G on a different band that is compatible with more handsets, so you might just be in an area where they have already done so, which mistakes you into believing that you are actually connecting via the old school AWS Tmobile bands, when you aren't.
I really need to decide which phone I want to take the risk on - The tmobile LTE is locked apparently, doesn't seem to show as many capable bands as the AT&T version, and also, I'm not sure what to bank on in terms of there being a software vs hardware lock (Would be nice if the tmobile can be unlocked via software to fully operate on all LTE modes that the AT&T supports).
I'm actually in Canada, and would probably end up needing to purchase the Wind version in order to get what I'm looking for (since Wind operates on the same AWS frequencies as tmobile). But losing out on Bell/Rogers/Telus LTE in the process is just something I don't want to do either.
Going to have to see what can be unlocked via software on all these different phones................
I would also appreciate a response from someone if this is possible... using T-Mobile ROM and modem to work on At&t (with aws frequencies).... just like the S2 I717 mod which after flashing was working with aws frequencies....

Yes... it should... as soon as I get my dual sim card adapter for the Note 2... I will post a million results/combinations here on T-Mobile and AT&T forums... I just don't want to open the back cover 30 times a day and swap sims a bunch of times... with the adapter I just insert the 2 sim cards and done... testing all the way from that point on...

I have the SAMSUNG-SGH-I317 from AT&T, unlocked via unlock code from AT&T. No root, stock AT&T android 4.1.1. I got the t-mobile microSIM card with an unlimited talk and 2GB unlimited data plan, but I can not get tmobile 3G/4G working reliably. I get HSDPA/HSPAP/UMTS/EDGE randomly. 80% EDGE, 20% high speed between 4-8mbps down, 0.7-1.9mbps up. I am in Los Angeles, CA.
I know my SGH-I317 does not have the 1700MHz antenna needed for t-mobile 3G/4G data, but somehow I get 3G/4G 20% of the time. I have not adjusted any special settings on my phone, other than to reset the APN to default epc .tmobile .com. My guess I am getting 3G/4G via the 2100MHz antenna for download, but without the 1700MHz for fast upload, I get 0.7-1.9mbps only. But most of the time I am stuck at EDGE.
So has anyone gotten the AT&T Note II to reliably work on t-mobile 3G/4G? is there a special setting I need to enter on my phone? does flashing the t-mobile ROM on the AT&T phone solve any of the 3G/4G issue? or will I lose the unlock on my phone when I root or when I flash t-mobile ROM on my AT&T Note 2?
Any help greatly appreciated.

Hey I got a unlocked & Rooted At&t Note 2 on T-mobile running CleanRom with perfect 4g. Before I rooted my phone I changed my phones modem to T-mobiles because I only had edge. After that I have flashed several different At&t Roms and still have 4g. On speed test I get about 7-9mbs download and 2-3 mbs on upload not the best but way better than edge

I am actually using the CleanROM 4.5 (haven't flashed 4.6.1 as I do not see much new on that ROM). I am actually using it on the stock kernel because I am not a huge flasher like many of the members here. Since Note 2 is my daily driver, I don't want to keep updating it and customize it after each ROM flashing. I like the CleanROM 4.5 since it was the way I got it and I just updated to the new version. The battery life is pretty good as I can last a day or more with moderate use.

So you reflashed the LTE modem and it is running fine? or you went back to the HSPA+ one. Right now I am on T889UVALL4. To scared to flash back the LTE one. Maybe when I get more time to deal with a loss of imei again I will try the LTE one again.
Update: Flashed the Tmobile LTE modem again and is running fine thus far.

Not much of a guide really out there. I flashed the tmobile modem for lte, lost my imei, managed to restore it and now have lte. Although I am now stuck with a tmobile modem. If I flash a t889v modem I go into a boot loop. Think it would be best to wait until there is a proper way of getting it done.

are you on a canadian carrier? I want LTE for bell on this phone.... it doesnt matter if i lose the wind, videtron and moblicity compatability as only videotron is available where i live, and they're no good for me.
Yes im on Telus. Check your pm.
You don't even have to lose AWS DC-HSPA as I found out last December after dropping by a Videotron kiosk. This was further confirmed by Sjravi's tutorial to enable AWS on the I317.
i have just 1 question, is your battery life the same after you enabled LTE? now i can go about 1-2 days with heavy usage on my phone without having to charge it. just wondering before i jump in....
I've modded my phone early enough that I don't have much basis for comparison, but I have no issue going through a heavy usage day with plenty to spare. Trying two might be pushing it, but I've done it with low usage days. YMMV.

and it shows LTE next to the signal bars?
No I dont have the lte icon, not included in this rom. But when I go to about phone status It shows lte. Getting 42mbps down and 21 up
First of all i wanna say, you all do an amazing job with all of this. So ive been looking around the forums and i cant find an answer to my question, so i will post and wait for replay. i have the at&t version (i747) of the gs3 and had updated to 4.1.1 via kies. early march i found a post on your forums about sim/carrier unlocking and tried it out. it worked w/o any problems, so i headed to t-mobile to jump on their monthly unlimited 4g plan. installed sim and had no problems. all functions work: calls, im, sms, mms, data (edge, 3g, and HSPA+), everything. on march 17th, i decided to try out a custom rom. i odin rooted my phone with cwm then tried out [ROM][4.2.2][STABLE] LiquidSmooth v2.1 - d2att - 3|16|13. works absolutely fine. sorry for the long wind but i just want to make sure i give all info before posting my question as i may prevent unness replies. having an at&t phone using tmobile as the carrier, can i use roms intended for t-mobile only, or do i have to stick to at&t/multi-carrier roms only?
Honestly making sure you have a T-Mobile put in is all that matters. Other than that they are fairly interchangeable.

I have been making roms, from Canada claro i747m, and tmobile t999 and att 747 and they all work as they should. no problems at all, using stock att modem i747ucdlk3 without any issues...
all I did was change the build prop to represent d2att..
I have simplemobile which is a tmobile company.. except for now I just used up my 4g.. I usually get 3g, but for some reason im getting an E which speed is like 2g edge.. slow at the moment.. never seen that in 3 months..
check my signature, for my roms... they r all stock original roms..
I'm in the same situation as the op. I have at&t i747 unlocked to use with tmobile. My question is, if I flash a multi-rom What carrier do I choose during the aroma install? do I pick tmobile because thats what network im using now or do I pick at&t because its originally an at&t device? any help or advice would be greatly aprecciated.
during the install of liquidsmooth i chose att since i do have the branded phone. i cant use the lte settings for network cause tmob doesnt have their lte out yet (soon to drop), but i am wanting to try the tmobile install and see if i get any difference in data speeds. other than that, liquidsmooth is a pretty solid build. this is the only rom i have tried on my gs3 so far. id like to try others to maybe help give feedback for builders, i just wasnt sure if i could use tmobile or had to stick to att roms. thanks for the info.
on a side note, the rom unlocked a 1080p video record and i like showing ppl the OC ability. 1.9Ghz. YAY!!!
when I first made my Canada Claro rom d2can everything worked out the box. the only thing was it was showing me info of I747m, everything was still working, same when I made my tmobile rom, it was showing d2tmo, everything worked out the box, just that it showed me info of T999, so both of the roms worked, all I did was change the build prop to represent d2att ATT info..
So the answer is yes, u can use other roms... just be careful not to install the modem. I never changed that. I remove them from the rom.
Danger,, I tried making the international GT I9300 and removed the modem, changed the build prop.. almost bricked my phone, played with it to try to make it work, It would hang and sometimes not boot up... so stay away from international one.
so if u try Canada or tmobile u should be safe, its the same phones... or if someone post roms that are ported to att i747.
I am using i747 for T-Mobile.
Can somebody tell me what ROM i should use in order to get WIFI Calling on it ?
Thank you.
So I'm trading with my mother her T-Mobile sim for mine. She's going to take over my contact from Att and I'll take hers. Reason is her job well pay her bill but they want Att for some weird reason Lol. And i want the unlimited data with T-Mobile. So my question is once I unlock both phones, well I still be able to use my current rom? witch is avatar latest with KKO kennel. Would I just use an T-Mobile modem and radio or just stick with the Att radio/modem?

yea ROM shouldnt matter. Its all about the baseband or modem. Might want to hop over to the T mobile forums and ask them. Another thing you want to do with your AT&T Note is hack it so you can use T Mobiles AWS bands. The Chip in our phones is disabled right now but we have the hardware to use the T mobile bands.

Yea I'm going to. I seen an thread bought the aws band witch I plan on doing. I'm actually kinda glad my mother wants to switch the 3gb data is kinda killing me Lol. But I think an Att radio/modem should be just fine or i could be wrong.
It's actually very easy to enable the AWS band on the AT&T Note 2. T-Mobile LTE works out of the box, but for 3G (HSPA+), you need to flash a file from your computer. You don't have to be rooted though. It shouldn't void your warranty either or trip the flash counter: http://forum.xda-developers.com/showthread.php?t=2068041

Flashing another Note 2's radio (as in another carrier's/model's) to your AT&T Note 2 can actually damage it. Not physically, but you'll lose your IMEI for example and probably get stuck in a bootloop. Stick with AT&T modems. You have to reapply that flash from your computer any time you flash or reflash a modem though. But seeing as how most custom ROMs don't come with a modem, you won't be doing that often anyways.

Yea that make perfect sense. If im understanding corectly, since im going to be sticking with this rom for awhile. Once i do the aws band mod all i got to do is put the sim card in and i should be good to go.

Yes. Although you can change ROMs freely. This mod will stick until you flash a different modem (which is separate from a ROM), at which point you just flash it again.

And what bought kernels? Could I also switch kernels freely also?

Yes. Modems rarely need to be changed and are in a separate file 99% of the time. Kernels and ROMs and anything else can be changed as many times as you want.
What area are you in? You might see how it works stock unlocked on the refarming first. I'm quite happy with how my i717 does in Chicago.

I live in north part of Phoenix az And my mother gets 4g just bought any of the surrounding area.
EDIT: turns out ATT used a 3g only sim car when they activated my account. LTE is up and running smooth on my phone now!
I ordered a Rogers i257m to use here on att in the states. After setting it up I only get hspa+ and no lte even with updated apn settins.
First thing I did was rooted it with vroot, updated superuser.
After that I threw on twrp through odin.
Then I used regionlock away app to unlock the phone. (this is the part im skeptical about)
All was well while I was playing with stock rooted rom, it shows me on 4g (h+) and I was happy with data speeds and getting used to everything. I never thought about questioning if I were on lte since it said 4g.
I flashed slimkat and carbon 4.4's and both get only HSPA no plus and no lte. bluetooth also does not work on those roms. I tried flashing both 4.4 aosp kernels with no luck there.
SO I figured id go to sammobile and download the stock 4.2.2 image from rogers and toss it through odin. rooted with the rootkit this time and flashed twrp back after, still same problems.
WHAT GIVES?? I feel like I have tried everything possible, does anyone know any tricks to get me up to at least 4g and bluetooth on aosp!?
hours on the phone with att and they give me the answer that if teh phone is not an att phone origianlly you cannot get lte as it is not recogfnized as being compatible in their sytem.. i call bs, anyone else getting lte?
I got an unlocked Telus SGH-I257M (I presume it was unlocked with a code) and it worked fine once I changed the APN. It could be a problem with regionlock away but I'm not sure.

yeah thats what im guessing, but I have no clue how to undo what that app did and how to unlock it any other way
you can confirm you get lte though?
Yes, it does get LTE for sure. I believe regionlock away has an option to revert the changes it made. In order to unlock your phone the normal way you'd need to buy an unlock code. As I said I bought the phone unlocked already so I can't really help with that..
EDIT: Also keep in mind I an talking about LTE on the stock ROM. Other ROMs for the I9195 could have issues with the I257 variant phones?

An update to the thread. I was able to get LTE after borrowing an ATT s3 from a friend to add to my account and take to the store. they narrowed it down to a 3g sim card and not an lte one... go figure.
