How I got my GSM GN to work with ATT / ROM and Radio

My current setup on my GSM GN on ATT in Chicago.
Rom - CM 9-20120319-nightly-maguro
Baseband - i9250ugkk7
Kernel - 3.0.23-cyanogenmod-03753
My ATT account is not provisioned for 4g. Took my microsim out of my iphone 4s and used an adapter in my GN.
APN set to wap.cingular. I did not set this.
I just loaded CM via rom manager. I did flash that radio, which I did try a few other radios, but that one, just plain works.
I have no data drops, can switch between wifi and 4g without issues.
Speeds during the day are normal. I can now use my GN :>
Thanks
Matt

Not to mention the 4s should be provisioned for 4g anyways

Yes good guide! My steps were also similar to yours:
1) Put in SIM
2) Turn phone on.
Make sure to do both steps, or it won't work.

[Guide] Sprint/Verizon Galaxy SIII Flash to Page Plus Cellular Tutorial [Video]

I No longer support this thread due to the lack of time I have lately. This video will show you how to get up and running on P+ with 1x data only.
This wil work for the Sprint, Verizon and US Cellular variant.
Yes I can get 3G but, the method is not allowed on this forum.
Please don't PM me asking how to get 3G as I will not reply.
Hit thanks if you watched this video please

Wow awesome Nevell. Thanks so much for this.
A few questions.
How different would it be to flash Straight Talk?
After flashing can I load ROMS like CyanogenMod and such without issue?

On the Sprint one yes but not on the VZW one. As far as flashing to ST you would need a donor phone. I won't go into details but that should be a start for you.

OP updated with new Verizon GS3 fully flashed with 3G youtube video demo.

I have been trying to flash verizon gs3 to sprint, and have talk and text but no data, I don't know what I am doing wrong. I have tried everything. Thanks for your videos and help is appreciated

Why not just trade your VZW GS3 for a Sprint GS3 on your local Craigslist?

I do have the sprint one, but I wanted the GSM capabilities of the Verizon one cause I travel over seas.

Can You Develop 4G LTE Only Option On Sprint Nexus?

I am posting here because it seams no one knows why some phones have LTE only options and some do not.
I was wondering if someone can develop this feature somehow if the user is rooted and has there MSL code that doesn't have the LTE only option by Default.
Is this possible via development and if not why?

The only problem with going to LTE only is, on Sprint, LTE only supports data service. So if you went to LTE only you would lose voice service.

I want to lose my voice services. I just want to use my phone as a Data access point.
So do you know if someone can develop this feature?

ah ok, wasnt really clear in your explanation. any of the custom roms i have used i don't ever remember seeing lte only. sorry man wish i could help a little better.

It's possible to have LTE only, yet not many people can develop radios that shut out normal service. Good idea
Though!
Sent from my Galaxy Nexus using xda premium

Ya what if some one developed a ROM feature to where you can at least disable 3G so the phone could only connect to LTE. This could bypass the possible hardware limitations.
Sent from my Galaxy Nexus using XDA Premium App

Probably won't work but use efrants return to stock guide and instead of flashing both radios try flashing the LTE radio only and see what that gets you
Bloods thicker than water

I wonder why this is not more popular and why more people are not working on this possibility.
Sent from my Galaxy Nexus using XDA Premium App

Search in the Play Store for "Network" by Philipp Mangelow. It is actually a shortcut to the phone's built in diagnostics mode. It doesn't work for stock or ROMs with stock kernels, but I have used it to put the phone into LTE-only mode for testing. You will see both GSM and CDMA settings, regardless of which one your phone is. Try them all, sometimes the setting is mislabeled (its a bug with the ROM, not the app).
So in short, even if your ROM doesn't support LTE-only, you have a good chance of this feature with this app.

Okay there was nine options under preferred network tab and all of them did not force LTE. I do not know if I have to reboot or not but if you know anything else that would be great or have any other ideas.
Also there was something about ims registration but I do not know anything about that.

The LTE option only appears on certain ROMs. I forgot which ones, and I can't check right now because I flashed back to stock so I can take my phone to Sprint for repairs (overheating). Try Eclipse, Maddoggin, Carbon, Rasbean, or Jellybro. One of those will have an LTE option I'm sure. What I do is set the LTE option, then below I turn off the radio, and then turn it back on. Oh and sometimes the 4G icon doesn't appear, depending on the ROM, but if you do a speedtest you'll obviously see you're connected to LTE.

Okay I have tried all of them by turning off the radio and turning them back on. Also did not pay attention to names. It still did not work so I guess I will have to try one of those Roms.
Do you know if I can install one of those ROMs with the sprint nexus toolkit? And which ROM would you suggests first.
Also im afraid it might be a hardware issue do you think that is possible? Maybe I got one of the first Sprint 4G LTE Nexuses that you can't split the LTE signal.

no he didnt need to. that is why i reported them.

It takes about the same time to answer a question than to b*tch about it...
ANSWER: Download and flash Eclipse 2.1 ROM (Android 4.1.2) :good:
It has the LTE ONLY option you want. It also has a fantastic array of options and tweaks, and 2-4 times the battery life of a 4.2 ROM or Stock OTA. :highfive:
If the LTE ONLY option doesn't work on the the first try, use the Network app posted above to turn off the radio and back on again. :victory:

No, it permanently unlocks those bands, just like carrier unlocking a phone. Once it's done its done.

No. The T-Mobile version, T-889, is a dual cell phone capable of supporting 42.2 Mbps data transfer. The AT&T version, i-317, is not and is limited to 21.1 Mbps. However the i-317 is capable of using more than one LTE band whereas the T-889 is limited to just one.

No, you can flash other carriers roms. The thing is you have to make damn sure what you're flashing isn't gonna brick you. From a software standpoint all Note 2's are the same, for the most part. You have to be careful not to flash another carriers modem or you'll have no signal. If that happens just flash an AT&T modem and you're good. The kernel is pretty much the same. There might be some minor differences but nothing to worry about. Just read read read. All the info is in the OP, and if it's not just ask in that thread.

Cannot lock on to a 4G signal on my SM-N900T

Hi
So I have a T-mobile unlocked SM-N900T that I'm currently using in London. I'm on Lycamobile and want to try their 4G network but for some reason my phone just will not connect to LTE. 3G works fine but that's as far as it will go.
I've been able to use 4G in India on the same phone so I know it does work, but for some reason it just wont connect here. I've tried the *#2263# service menu and selecting LTE -> ALL just gives me the no signal / network icon.
Have tried resetting, pulling out the battery and SIM but nothing seems to work.
Has anyone had these issues or any suggestions?
Oh - phone is Unrooted and running the latest KK update.
Any help or advice is graciously accepted. Cheers!

They just might be using a band for LTE that the phone doesn't have/support.

Thanks Andrew. I'll give that a go. They've called me a few times but keep reading from the same script. Was promised a call back on Sunday, but nothing and its Tuesday already!
They don't offer contracts as they are only PAYG but let me look up specs for O2, as they piggyback their network.
Sent from my SM-N900T using xda app-developers app

Ok. ..so it would seem that the tmobile phones operate on different lte bands. So I've attempted to flash an international rom on this phone and as the Eagle eyed will note, this was done successfully. I should therefore have an international modem etc now? But I still can't connect to 4G! So does this mean that this is a device (actual hardware) issue or can this be sorted by flashing a modem that allows me to connect to all bands?
