AT&T D950 confusion.. - LG G Flex

First. yep I'm trying to learn what I am doing lol I have only messed with a HTC Sensation a couple years ago. Now with A AT&T Flex D950, from what I read is the Flex1. mine is Ver 4.4.2, Kernel 3.4.0, Build KOT49I.D95020g.. What I have done is fire AT&T, unlocked sim, went back to T-Mobile, and rooted.. I have no LTE but all else seems to be fine.
I started looking in to fixing the LTE issue, de-bloat, see if I can get the other T-Mo functions to work like WIFI calling and so forth, maybe do more. Needs to be good for my daily device.
The more I have read, the more I am confusing myself about what I can get away with. Like what works across flex models, radio drivers that work with what I need and so forth. Need some advice/help to get me on the right track. I would like to stick with my flex so any help would be greatly appreciated..
Please keep in mind I am learning as I go here

You should do some research on what LTE bands in your area that T-Mobile supports. Maybe the at&t model/radio doesn't support those bands.
What Sim unlock method did you [email protected]_XV6700 has some experience with cross Dll and radios. I would point you to his thread..... But its been deleted

Thanks for the post!
I unlocked with the code number. I will look in to dll and radio mods by trying to PM.
I could be wrong but I'm thinking LTE is another problem, unless T-Mobile is not using a band we have in common in Calif. I travel a lot and have not seen LTE anywhere to include Bay Area, So Cal, and the central valley. I could be wrong about that tho. Maybe I'll get lucky and find out about a radio mod that helps. My Samsung's have LTE band options, and this Flex has no such options to be found..

D950 also has LTE band options through the secret menu.
Use 3845#*950# from dialpad to access the secret menu, got to LTE only menu and you have the bands there

I use the "Network" app from the playstore to switch bands. The reason I asked is because I unlocked my sprint branded g flex to use with cricket, and the sprint radio does not have the LTE bands for at&t/cricket. But H+ works just as well in my are as LTE.
Here is the supported model bands, but not sure of usable bands in your area:

That's not working on mine,well it works just shows nul.. I went into build.prop file last night, changed att to open. I now have LTE with 39mbps down speed ? thinking I need to go back in that file and change any "att" to open or tmo? Was also wondering if I change model # to tmo flex # would that open up stuff on network like wifi calling?? I don't want to go too far with the build.prop file lol I know if I screw up that file I'll have to wipe and start over, if not brick this thing..

LTE is working now, went in to build.prop file and changed att to open. That opened up bands on it's own. Seems that's what had it locked to att band's only. Do ya know what else I can get away with modifying build.prop?

Make a nandroid backup, backup your EFS partition. Save it on your computer, and you can save your phone from most bricks. There is a couple of band mods on the g flex 2 section of XDA that use "shortcut master" from the play store, check it out.
Also check out xposed, its awesome.

There's a thread in the AT&T G2 section where a T-Mobile rom was ported to the AT&T variant:http://forum.xda-developers.com/att-g2/development/rom-t-mobile-4-4-2-stock-d80120e-wi-fi-t2819587
I only have satellite Internet service, so I haven't downloaded it to try and dig through to figure out how he did it.
Looking at porting guides, it looks easy except that the WiFi calling is in the Framework folder, or so they say. Maybe someone here who knows what they're doing would be willing to embark on this journey for those of us who could use it.

[Q] Does a rooted T-Mo N1 work on AT&T?

Hello community,
I couldn't find any info through the Search, so I was hoping someone could let me know if a rooted Nexus One for T-Mobile would work on AT&T. I have the unlocked bootloader, custom recovery image and ROM, the whole 9 yards, but what I don't have is the understanding about GSM networks and how the modifications I made to my phone affect the cross-network compatibility.
Any help is greatly appreciated. Thanks guys.
The two models operate on different gsm bands. An unrooted t-mobile n1 will work on att, but only on edge..

Rooting should have no affect on it.
And if its the TMO version of the phone you will only have 2g (edge) on ATT. Seeing as both networks use different frequencies. And the cellular antenna will only be tuned to pick up 3g+ signals from TMOs frequencies.

But AT&T doesn't allow apps to be installed via apk files. So no 3rd party stuff.

You are so painfully incorrect. At&t has no presence on this phone. Get your facts right before you post here.

[Q] Unlocking xt860 for USA

So i'm travelling to the states for 5 days and someone suggested to me instead of paying for a bunch of roaming add-ons from Bell, i may be better off to unlock my phone and get a sim card on a pay as you go plan. Is this possible and more importantly is it worth it?
Any advice is appreciated
I would personally bite the bullet. It'll probably cost you about $20 to unlock the phone and then you will have to get an AT&T SIM card or pay as you go, probably won't have data on it, etc etc... Last time I went down to the US I spent about $50 on roaming. You're only down there for 5 days, how much time do u want to spend screwing with your phone?
Another thing you could do is turn on airplane mode but keep the wifi turn on, and get a google voice number. Pair that with GrooVe IP, and you have a $5 wi-fi only solution.
The data is what I'm more interested in. My phone will double as my GPS unit, and Google search to find stuff to do. Bell charges 30 bucks for 10 MB.
I'm probably gonna e doing 4-5 trips a year to the states, on a pay as you go I could probably just reload everytime I go down, once I have the sim
Sent from my rooted xt860
Just go to Crackberry, go to the SIM unlocking section, find a site that allows you to unlock for free, then yeah T-Mobile has prepaid service, or maybe AT&T I don't know. Anyway, you get the idea.

would this work with tmobile's 4g/3g network?
Stanley,
AFIAK the 3G frequencies used by T-Mobile is AWS, which the XT860 is not compatible with.
Hey guys sorry just a quick question...
Would the Bell XT860 work on Rogers/Fido once it was unlocked? Has anyone actually tried it?
The reason I ask is because I've read that apparently the Verizon Droid 3 was not compatible with Fido/Rogers even after being unlocked.
Thanks
Bell XT860 definitely works on Rogers when unlocked. I'm using one right now on Rogers. (Just running the Chinese ME863 ROM on it right now). When i was on the stock Bell ROM it also worked fine.

I know nothing about this stuff, but google search tells me that t-mobile uses 1900 MHz GSM and 2100MHz UMTS which are both supported by the xt860. They also support HSPA+
does this not mean the xt860 should work on t-mobile?
The phone would need the phone to support the 1700mhz band as well.

Hey fireeater,
I just ordered an XT883 that will be unlocked and will be used with my T-mobile sim. T-Mobile uses 1700 & 2100 for their 3g while AT&T uses 850/1900. Do you know if the agreement between AT&T and T-mobile will allow the XT883 to get 3g with t-mobile?
Tmobile is refarming their 3g. So you will get 3g by the end of the year.

[q] how can i enable mms and lte for at&t?

I have a verizon note 3 sm-n900v that I want to use on AT&T. I have rooted it and accessed the service mode screen and enabled b4. I have set up the APN and I am able to send and receive texts and make and receive calls. My data works, but it is on H and H+. I can not get on LTE or send MMS messages....can someone please help me?!
I have read that AT&T runs on a different LTE band, so I am just checking to see if this is true and also ask that if I pay for a factory unlock if it will fix it so that it operates the way it is supposed to.
Thanks

Well Verizon is CDMA where att is GSM, totally different and not sure it is even possible.. Odd that you can even see it.. this is probably your issue. Only other provider I think you can fully work on is sprint (and other mini ones that are CDMA)

actually tmobile works fine on it. You can switch the APN to gsm and it works just fine. The verizon note 3 is the only one that came factory unlocked to run on any network...you just need to tweak the settings.

Moto X 1095 Pure Edition on Cricket LTE issues

I was having some slow data connection so decided to call this AM. To my surprise they are telling me that my phone is not compatible with the Cricket LTE towers. It even shows I have LTE on the status bar.
How is that possible other than them not wanting to give me LTE since I did not buy the phone through them?
I might as well switch to Straight Talk if that is the case.

They're flat wrong and just trying to get you off the phone. With the Lollipop update the Pure edition supports all of AT&T's LTE bands (2/3/4/5/7/17) so it also supports Cricket since they are an AT&T MVNO.
If you check out Howard Forums you'll see that you're not alone in experiencing slow LTE speeds.
http://www.howardforums.com/forumdisplay.php/336-Cricket-AIO
On the Cricket website there is a compatibility section where you enter the IMEI number it says the phone is only compatible with 3g not LTE. Makes no sense.
Just gonna keep it simple and switch to Net10 or Straight Talk instead of worrying about it. If they want my business they shouldn't be inaccurate!
I'm on cricket wireless and I have to build an APN for LTE to work.

I never send mms but I just tried it to make sure it worked and their pushed settings was wrong as well. I did the same as you. You would think that they would get the apn setting right. I've had LTE the entire time, just no mms.

My theory is this: for whatever reason cricket thinks our phone is 3G only (run your imei on cricket's compatibility checker) and therefore pushes apn settings meant for 3G phones.

Did you download and use the LTE Discovery App? It needs to reset your modem. Also double check to make sure you entered the apn exactly the same. No phantom spaces, etc. There should be no spaces in the "apn type".

I am using a T-Mobile Note 4 on ATT network and have no issues. First of all make sure LTE is enabled on your number/simcard. If not call the customer care and ask them to enable LTE on your line. They will ask your device IMEI number and then enable it. If not u will only get a 4G signal on your phone

I have tried that one already :/
The service rep said this "You are getting LTE on your other lines. Because the device that being use on the line is sync on your account. Since the device that is sync on the line that ends with 1521 is the iPhone 6 Plus. The Note 4 does not receive data service. Because it is registered on the iPhone 6 plus." how legit is that?
If u have a phone on contract on that line, then I use guess it is difficult. Or you can go to an ATT store and say that u lost your sim card. Ask for a new one and say that it is for an Android LTE smartphone.

According to this thread, you also have to go to settings, more networks, mobile networks, network mode and change to LTE/WCDMA/GSM.

I know people are successfully getting LTE on T-mobile Note 4 on AT&T service, though I am not sure which APN settings they're using. Looks like there are at least 3 in this thread to try... but it may be a block from AT&T ? I can't imagine that's the case, but I honestly don't know exactly how much control they (AT&T) have over what bands a given sim card can receive if its not matched to the imei on file in their system? I guess a lot?
OFF TOPIC: How much did you guys pay for the unlock codes? (curious)
LTE works great on this phone with AT&T service. Been using it without issue for months.
I don't know why this person is having issues. Only thing I can think is that the Sim card is bad.
Paid $30 for the unlock.
My AT&T account doesn't even show a smart phone. See the screen shot below. As long as it says LTE device then it's not AT&T causes the problem.

I don't know why I'm having issues honestly. I'm trying everything that's thrown at me , I even got a new Sim card yet no LTE. I don't even care if it shows LTE indicator , but it's that my speeds are so slow. 2-5mbps download while on my iPhone 6plus I would get 50mbps download.
