Hey guys, noob to rooting and pretty much anything with android that's custom here,
Just bought a korean version g2 the f320k version. Phone works for making calls and sending text messages, but will not connect to their data network. Not sure if its because I do not have the 700 (lte) band range for an option on the phone when I enter the WCDMA service menu. I work for a subcontractor for AT&T and am somewhat familiar with the equipment they use. the LTE radios run off 700. UMTS and GSM is most common 850 and in higher priority areas 1900. doesn't appear that the phone supports UMTS bands either which might be part of the issue. I have done all sorts of tweaking with the frequency bands and that kind of stuff when you enter "5457#*320#" but none of my combinations seem to be working. Ive tried rooting the phone following the exact instructions on the rootjunkie videos, install seemed to have gone good, but root checker tells me i do not have root access, superuser installed during the root process, but something else must be out of date or something. Was hoping to be able to flash the phone with AT&Ts rom or something and maybe that would work. I live in the Minneapolis, St. Paul MN area...has anyone else had any luck with this version of the g2 working on US carriers? I really don't want to, but pretty much ready to give up on this phone, I've scoured this website for the past few days and cannot seem to find any solutions.
Can anyone confirm this phone, flat out, will not completely work in the US market? Please help android gurus!!! :fingers-crossed:
I'm reading through alot of the posts about rooting pertaining to the galaxy note 3 but haven't come accross this particular. I keep fiding a clue here and there but nothing with the dead on answer...if there is one.
so, i have a GN3 from verizon and I moved to T-mobil. You might see where this is going already. Actually... I was always with T- mobil and got ahold of the note 3 afterwards. I really like it but it was from Verizon. So i unlocked it and set the proper network, to GSM/UMTS (whatever that stands for)... I turned off the annoying set up wizard that keeps giving me foreign sim card alerts...which turns back on after a restart...so I want to find that bugger and delete it if I can...but thats for another thread maybe...
the phone works and messaging... at home I get my wifi BUT....
I'm st gill not getting the 4g or even the 3g signal.... barely gets though the "H" band? Not sure about the vocabulary..... You can tell I'm new at this but i have no problem tinkering around...
I tried setting it to global which does bring up the 4Glte symbol in the status bar, but it never lights up... like saying its there...but your just not catching it. that's frustrating.
I DID ROOT THE PHONE using Kingo which worked like a breeze.... I only did that thiking I could get some other options to get the 4g. I'm not a developer so i'mnot worried about getting some secret apps or anything.
And thats where I'm at. so, IS THERE or ISN"T THERE a way to get the higher bandwidth. and if it depends on the phone, how would I check. AND, why can I not get into the service menu I keep seeing on youtube. *#XXXXXXXXXXXX#
I put the code in but the phone does nothing. I haven't tried it since I rooted it though...I'll give that a go in a second...
Any help I would appreciate... keep learning one thing at a time
Thanks

Sounds like you need correct APN set for T-Mobile. In your case that will be FAST.T-MOBILE.COM
For T-Mo, the signal will Fluctuate between H+ and 3G. That's expected and depends on your area and coverage there.
Long Story Short H+ = 4G. T-Mo is deploying something equivalant to 4GLTE. Please see #3 on [Baseband] ALL T999, T999L, T999V, T999N Modems! w/ MAP and Data Tweaks! Although the thread is for the wrong device, that specific post clearly explains T-Mobile Coverage rollout and Signal map.
To your device, you may wish to review SpeedTest - Post your LTE speeds and where to tell you speeds to expect.
Since your device really is a Verizon Variant, please carefully review VZW Note 3 N900V Fully Functional on T-Mobile 4G lte (band 4) If you still have issues, please post on this thread.
Thread Closed. Thank you.
I've been scouring the internet trying to find a solution. I've been wanting this for a while. I did my research to figure out which model of the G pro2 worked with AT&T. It arrives and now nothing. I'm only getting G not 3g or LTE. I am a bit new to smart phones. I've tried everything I can think of. Am I using the wrong apn settings? Is there something in the band selection menu I'm missing. I'm at a complete loss what am I doing wrong?
In Dialer 5754#*350# and activate your Bands or 5457#*350#
Still no dice
I've gone into the menu and specifically selected the required bands but still not dice. I went into the lte band selection menu. Is there another menu I should go into?

I have yet to root my phone I am a bit of a newb when it comes to things like this. I do plan on rooting it and giving it a Skin that has a lot more english. I have done this I selected bands 17 and 5 for lte and 850, 1900 for wcdma and gsm. In the Band Selection Menu. Should I be doing anything with WCDMA Channel, LTE Channel, WCDMA Security, RAT mode, RRC Version, SMS MO Domain, Service Domain, any specific APN setting what is it on your wife's phone, EF file edit, HSPDA category, HSUPA category, GCF Test, OEM RAD Settings, SKT Auto Test, IRS Setting, CA Setting, LTE 3GPP Rel. VER. or anything else I am missing?
I've determined that my phone is a very good fake
IDK if this is real issue but if some does have this problem and comes up with a solution. Please post it here I was beyond frustrated and hope this problem can be solved for someone.
Try going back to 4.4 and using LTE
Try taking your phone to an AT&T store and explain it to them. They will install a new SIM card and associate it with your IMEI #. Then you will have LTE!

I'm sitting in front of a Tmo store waiting for them to open and see where that goes. Hey guys how's battery life with this device. For what ever reason when I did put a Tmo sim in this phone it got only 3g now the chip was a nano from my nexus 6 using a quality adapter but holy crap I've never seen a phone eat a better like Godzilla. Hell it killed the device in like 3hrs. Although when removing the sim it seems to go normal using just WiFi connection. Very strange device behavior. Does this phone have bad battery life in its normal state? Since I am a huge "Big Screen" fanatic I would probably just get the extended battery from the Japan guys on amazon. Your thoughts?

1. You Should have an LTE Sim
2. LTE Data service Should be enabled on It.
3. You have correct APN settings From your Carrier
4. You should be in LTE Coverage Area
Now go to Hidden Menu of the Phone. 5457#*350#
in WCDMA Service Menu
1. Slecect WCDMA Channel and Slecect Full
2. In LTE Channel Select your Preffered band ( You should Knew your LTE band or ask from Carrier)
3. In Band Selection Select your bands or select automatic
4. In RAT Mode select automatic
5. Check mar APN Edit Function.
You can also increase RRC Version, HSDPA Category, HSUPA Category and LTE 3GPP Rel. Ver. if your carrier supports you can get higher speeds.
Reboot Again
Press the Thanx Button
@ Murshad007

I'm having a hard time finding a definitive answer about which LTE band I'll lose using the tmobile variant on att.
I don't think any, I think both are identical. I am using the N920T with AT&t. I would suggest you consider using DarthStalkers ROM, he was able to pull the AT&T carrier files.
The N920T & A are the same. If you had bought the N920I you might lose bands.
Does anyone know where I can get a band 12 coverage map? I can only find the LTE coverage map which doesn't specify if band 12 is used there

17 and 30 (I don't think the 920t's band 12 will work with AT&T's B17 - even though 12 is a subset of 17 (or do I have that backwards?) Possibly 29 (downlink only for AT&T) - but there's very little documentation on B29, so I'm not sure if the N920A supports it or not.

Band 29 is rarely used by AT&T (only as a downlink in heavily congested areas.) This shouldn't be a problem.
Band 30 (WCS band) is something AT&T _just_ started deploying, but I've never seen it in actual use. In fact, until very recently, none of AT&T's own phones supported it. B30 is really of limited value for general use due to it's propagation (or lack thereof.) Like 29, its probably only used as a supplement to other bands. I wouldn't worry about B30.
B17, however, is a Big Deal for AT&T. That's AT&T's primary "lower frequency" LTE band. Because of the low frequency, it has excellent propagation (meaning it moves farther and through trees, buildings, etc.) They use this band to cover large geographical areas with minimal towers. If you will be using your phone in a non-urban area, B17 is almost essential for AT&T. (My phone spends the majority of the time at my home on B17.)
I haven't heard of anyone with a TMO Note 5 device (without explicit B17 support) attaching to AT&T's B17, but that doesn't mean it won't work. However, Unless someone confirms B17 functionality on the n290T from actual use (and not just what they think), I'd suggest assuming that it won't work.

An informative post if ever there was one indeed.
What app do you use to determine which hand your phone is connected thru? I have found this app "LTE discovery", and it seems my att note 3 stays connected to 5 mostly, or 4 for lte. But then for GSM is doesn't list a band, but appears connected. On her t-mobile note 4 connected to att, she stays on 5, but the GSM doesn't appear to be connected to anything..
We will be almost exclusively in the middle of a city, but as with anything that could change or in the event of a road trip..
Is there a place I can sit and study this information? Perhaps a website with all of this data? Or do you happen to work in the field?
In a sea of noobs, an informed person is a real diamond in the rough - I appreciate your time.

That's a good app to use. I also use my phone's diagnostic menu's, but I doubt AT&T left those enabled on the 'a' variant.[/QUOTE]

Is that with "lte discovery" that she doesn't appear to have any GSM side connection? She most likely does, as that's where voice calls will take place...

Google. Then google some more. If you run out of pages from google, use another search engine. All the information is readily available - it just takes time to find it all.

so i got through all the hoops.. don't have LTE ;-(
it connects to band 4 or 5 when i first come out of airplane mode, but it jumps right back off. stuck on 4g. called at&t for an hour, they said initially it wasn't provisioned on my sim card, but then afterwards they determined it was a problem on my end, walked my thru APN settings and then ended the call.. still no LTE.
do you have an opinion of what i could do?

Quoting me in a thread was enough... didn't have to also PM me...
@TEKHD has a firmware that might work for you. Check it out over here: http://forum.xda-developers.com/tmo...h6-tekxodus-n5-urv1-00-00-lollipop-5-t3201869
He has apparently provided a mechanism that is working for other AT&T users... (probably via loading the AT&T RIL libs.)
I haven't tried this (and I don't even have a 't' variant myself.) On the other hand, a quick search of that thread seems to show that other people are having successes with AT&T sim's on 't' variant devices.
Good luck!

Apparently, you already found it: http://forum.xda-developers.com/tmo...on-1-aroma-t3212091/post63516726#post63516726
This has AT&T RIL's in the update.zip, and from a quick look at the first post in that thread, they are installed based on an aroma installer. Others in that thread claim it works for them. You're using a TMO device on ATT, so you have to expect some level of incompatibility. There are AT&T LTE bands that the TMO device simply doesn't support. It doesn't matter what happens with your Note 4. Different device and different modem.
So, if you want to use a TMO device on ATT, you'll have to make some sacrifices. Most people will find the sacrifices are less drastic using an international version of the phone. For some reason, US carriers go out of their way to ensure their devices are incompatible with each other.

ok this is where i started, by flashing the ATT option for this rom. but that doesn't solve the problem. i'm in the process of clean flashing the tmobile choice like he suggested.
thanks for all your help.
i'm afraid this isn't going to work either. i realize the wife's note 4 may have different hardware, and isn't a good reference.
i can see the thing connect to band 5, then band 4, lte .. but it's in "emergency calls only" mode, then it gives up on that, connects to HSUPA or HSPA+ and that's the last of an LTE connection.
i feel like it would connect if it could, and that i'm having a software issue.
problem solved guys sorry for the large headache..
Solution:
AT&T did not recognize my IMEI as being LTE capable. Because of that, they decline to allow my phone to connect to LTE. My phone would connect to an LTE tower (as in the screen shots a few pages back), but wouldn't receive anything back from AT&T, so it would say "emergency calls only" and then give up after about 10 seconds, and then never go back. Crap data all around at this time.
What you'll need to do is walk into an AT&T store, take a picture of the IMEI off an LTE phone, and then call in and change your IMEI to the phone you found. This will cause the system to recognize your phone as LTE capable, and like magic, you'll have LTE.
I can confirm that I have a tmobile branded unit that attaches to band 17. It isn't as frequently as on my note 4, I'm generally on band 2. With that said I've had virtually no trouble with service. I was initially worried about the b17 issue, but it hasn't seemed to make any difference.

Hi folks,
I've got the US LTE original Shield tablet, which is the replacement that NVidia sent me for my original "pyro edition" tablet. Since ATT haven't released the Nougat (Android 7, software package 5.0 or 5.1) builds for this tablet, but the ROW tablets are able to get this update, I flashed my tablet using adb/fastboot with the full ROW 5.0 package downloaded from the NVidia site. I then connected to WIFI, and let it pull down the 5.1 update. Factory reset, flash TWRP, rooted with SuperSU. Easy peasy. Then I set up the tablet with my accounts and such.
Based on good info from user @Son-j I made two build.prop edits, changing ro.build.flavor to wx_na_do-user (was wx_un_do-user) and ro.product.name to wx_na_do (was wx_un_do). This changed the reported signal type from H+ to 4G. Unfortunately I'm having trouble finding the thread where he suggested doing this. I think it was on the geforce web forum.
The only problem I've found so far is that I'm not getting LTE speeds. I was in Chicago for a couple days, in an area with strong LTE signal, and my other devices were reporting LTE and getting ~20Mbps down / 10+ Mbps up. My Shield was pulling maybe 8 Mbps down at best , and 1-2 Mbps up. At home in my suburban location, the difference is negligible (most devices here do 5 Mbps down / 1 Mbps up, LTE or 4G).
Still, I'd like to fix this if possible. Are there further edits or flashings that will let my US device running the ROW build get LTE? I have gone in and verified that my APN settings are the recommended ones from ATT. These showed up automatically, and matched the ATT recommendations.
Thanks in advance!
Hi I'm not sure but I there was a thread here in XDA that says it's still difficult to change the LTE (RoW to US, and vice versa) bands because developers couldn't find yet which part of the code to modify... It's not also confirmed if it is indeed possible to change the LTE bands to support.
So basically, flashing RoW LTE on US LTE device will still result in US-LTE supported bands. That's what I understood.
But what you did is quite a revelation. Can anyone else confirm that modifying the build prop will work? Boy I'm excited!

Hi @Son-j -
Thanks! Do you happen to remember which thread had those two buildprop edits? I found them after seeing a post from you a few days ago, but now I can't find it at all. My google mojo has fled me.
I'd like to have a link there so others can see the original source.
It would be nice to get LTE speed, if someone knows how, but most places where I use the tablet don't have super fast LTE, so the difference for me isn't enough to make me downgrade to the marshmallow US LTE build. I'll stick with nougat for now, and hope eventually to get full speed. Who knows, maybe ATT will eventually release the 5.1 US LTE build...
For clarity here is the set of APN settings I'm using. I'm going with the column in the center at the bottom for Tablets:
https://www.att.com/esupport/article.html#!/wireless/KM1062162
All of this was correctly entered by default except I did need to edit two keys:
APN was listed as broadband instead of Broadband (yes, I'm picky, but wanted to match case)
APN type was listed as just default. I edited it to match the listed setting of: default,mms,supl,hipri,fota
Also I'm set to LTE for "Preferred network type"
Ok I think there's a misunderstanding. Uhm, I'm trying to look for the related posts here at the Nvidia threads but it seems to have disappeared.
Just to set something straight, LTE speed is influenced by:
1. LTE device with specific supported LTE bands
2. LTE sim
3. Location with LTE signals
I take it that for your specific device - US LTE Shield Tablet (just like mine) - you satisfy all 3.
For the record, flashing RoW LTE on our US device won't change the supported LTE bands (check baseband code in About Tablet section of settings). So if you used to have AT&T LTE speeds/signals using US LTE ROMs, it shouldn't change if you flashed RoW LTE ROM on the same device.
We are speculating though that there might be a way, software/firmware speaking. We are hoping it's not hardware-baked.

Thanks Son-j. It kind of freaks me out that just a week ago I found the thread that recommended those two changes in buildprop, but now I can't find it, and apparently neither can you! So maybe I'm not crazy, since it's more than just me having problems finding it.
Anyway, yes, I used to get the LTE indicator on the tablet, when in an area that has decent reception of those bands. At my workplace, which is a building built like a Faraday cage, we can get only ATT service, via repeaters spread throughout the building (I switched from Verizon in part due to this). Phones almost always report ~3 bars of LTE in places I usually find myself within the building. However, speeds tend to be <10 Mbps (tested using Speedtest.net from either my phone or tablet). So, despite getting "LTE service" there (prior to my software update), the speeds were nothing so great. For this reason, I'm not TOO worked up that my US tablet running ROW software isn't reporting LTE... most places where I use the tablet don't have blazing fast LTE, and the difference between the 4G service it actually gets and the LTE it "used to get" is not that great.
I would like to fix the problem if possible, but it's not a critical thing, and I may just put it on the back burner until the US LTE 5.1 image comes out, then flash back to that. I've got lots of other fish to fry these days.
Always interesting discussion. Thanks Son-j!

If it's just a speed issue, that will be the provider's end. If it's a signal issue, that's device problem.
It's possible to get an LTE signal but with HSPA speed in some areas.
There is an app called LTE Discovery. It will tell you which band it is currently connected to. I've got it on my tablet on T-Mobile. I am having problems with it connecting to anything other than 3G. But I have read others with the Shield tablet having similar problems with T-Mobile.

Thanks @caseyatbt,
I was unaware of that app. I downloaded it on my phone (which gets LTE just fine at my house, most of the time) and it reports all kinds of fun stuff about the LTE signal it's connected to. On the US Shield tablet running ROW stock, this is what I get, which frankly makes me think the tablet is connecting via CDMA of all things, despite having chosen all the correct options in the Settings / Mobile section:
The fact that my radio seems to be connecting to WCDMA instead of GSM is kinda freaking me out, folks.
I'm tempted to try flashing the US LTE device Marshmallow recovery image, and see if that fixes it. I understand the flashes don't change the baseband, but since I flashed 5.0 and the the device did an OTA update to 5.1, that might have changed the baseband, eh?
So, if me flashing the marshmallow files doesn't fix it, I might reflash an earlier edition and let it OTA to latest edition, which presumably would install correct "latest" baseband for the model.
We'll see ... I'm still not committed to one direction or another.

OK, I just flashed the 4.4.0 version of Marshmallow. (full flash of all Nvidia recovery image files). After letting it reboot the first time, it checked for update and found none, as expected.
NO LTE. Downloded the LTE Discovery app, and it still only sees WCDMA signals. Uggh.
Now I'm going to install the 4.3, and let it OTA to 4.4, and hope that refreshes the modem/radio. If anybody is following this, wish me luck!
EDIT: OK, I'm in idiot mode. I downloaded what I thought was the 4.3 US LTE image and it was actually the 4.3 ROW image. I didn't notice this until after flashing, and seeing the H+ icon, and noticing lack of ATT usage tracking app. Oops.
I don't see the 4.3 US LTE image on the site; I'm now downloading the 4.1 image, and will do OTA updates from there, checking as I go how which signal my radio is getting.
No Joy.
I flashed US LTE 4.1 image. AFter the flash, LTE Discovery still reports just HSPA+ signal from WCDMA towers. I then let it take the OTA for 4.4... the latest available for the US LTE tablet, and after it ran through its update process, I'm still on WCDMA.
Uggh. I doubt there's any WCDMA signal where I work so I may have killed my tablet, at least as far as using it at work is concerned.
I'm sure there IS a path back, I just can't imagine what it might be, at the moment. I'll start a new thread to be more specific to this current problem.
Sigh.

Eventually found that thread with the buildprop changes, see here if interested or if you ever need to find it.
I just checked my Shield on T-Mobile. In the same area on LTE Discovery that yours says W-CDMA mine says the same thing (under Neighbor Cells). When you scroll to the bottom, what does it say for carrier?
Carrier: AT&T (310410)

Here are screen shots of my sim status (personal details redacted) and the LTE discovery window:
I am thinking that it is possible that W-CDMA doesn't mean what we think it means. It shows you connected to AT&T so you are not on someone elses network.

I talked to ATT. It's sort of their backup network, not available everywhere. My other devices definitely show LTE. Will post a screen so from my phone a bit later which shows that.

Here are some pictures taken from my phone, which is working properly. In settings, you can see the LTE network type and in the LTE Discovery app screen capture, all the LTE towers.
ATT maintains a "vestigial" WCDMA to allow some level of connectivity by devices that don't have GSM/LTE, but it's not everywhere and it's pretty slow.
The Shield used to show LTE in the Settings Cellular network type, as well as giving the LTE icon, when appropriate. Now it's just HSPA. Sigh.

My T-Mobile phone shows similar to your phone with LTE. T-Mobile must have a similar vestigial WCDMA that is showing up on my tablet. I still haven't found anyone that was able to get T-Mobile LTE working after it was only giving them 3G and HSPA. I have heard it either worked or it didn't.
