[Q] Only finds AT&T network

PLEASE HELP
My Galaxy Note 2 (SGH-T889) has been flashed with mr Robinson's "root66_TMO_T889UVUCMK7_2.7z" (baseband T889UVUCMK7)
The phone boots fine to version 4.3. I have a T mobile sim card in it
Device info is
Kernel version 3..031-2085660
Build #: JSS15J.T889UVUCMK7
Network mode is set to LTE/WCDMA/GSM (auto connect)
When I search for all available networks i only get AT&T (I need T mobile)
I have another Galaxy Note 2 (SGH-T889) flashed with the same mr Robinson's. Same settings, when I search networks it finds them all (T mobile, AT&T)
Is the phone that only get's AT&T network locked to AT&T? or could there be other reasons (it is an SGH-T889)
I was reading that if you flash T889UVALJ1 (4.1.1) you can unlock the phone (although I don't know if it is locked, how can you find out?)
I tried loading it but I think the 4.3 boot loader stopped it from working.
Should I get a custom boot loader on the phone? is so how do I do this (I read something about goo manager?)
Please provide details as I am a newbie.
is there something else I should be looking at or doing?

If it were an att note 2 it would not be the SGH-T889 it would be i317. What does your APN settings show? if you are on the 4.3 bootloader I don't think you can use odin to go back to uvalj1. if you want to unlock I have heard of people only flashing the uvalj1 modem and having success. Custom bootloader? Do you mean custom recovery? you can download that from goo manager. Do you not have a recovery installed (CWM, TWRP)?

APN = T-Mobile US LTE fast.t-mobile.com
I do not have a recovery installed (only Note 2 standard recovery?)
How would I download custom recovery from goo manager?
Can you lock an SGH-T889 to AT&T? (if so, how do I flash uvalj1 modem(?
Could anything else be causing it to only recognize AT&T network (and not T-mobile)?

Install the app and open it. Tap menu then hit Install OpenRecoveryScript. Tap Yes. Verify that the filename displays your device's code name and hit Yes. The file will download and your device will reboot and install the recovery automatically. source: http://teamw.in/project/twrp2/123
once you have the recovery you can flash the modem
I have not heard of locking a tmobile phone to att but I could be wrong. Are you not getting service at all?

Since AT&T is the only network recognized and I have t-mobile service I have no voice or data service on this phone. My other SGH-T899 which is flashed exactly the exact same recognizes other networks as well as AT&T

Not to be goofy, what is the model number printed on the sticker under the battery?
When you boot into download mode, what model does it show on the screen?
Edit:
Go into the dialer. Dial *#2263# and tell us what setting the asterisk is next to, automatic is the preferred one. Check and see if you can tell which bands are selected in the various GSM/WCDMA/LTE selections. I don't think you can, but it couldn't hurt to look.
Hastily spouted for your befuddlement

By Sim unlock, do you mean you want to use an AT&T phone on another carrier? If that's what you are looking for, give me a few minutes to test something.

Yes, of course.
But I am fairly new to the note 2 so I don't have much stored up information. I now see a post that indicates that flashing a certain 4.1.1 modem, MJ2 I think, gives the user a service menu where you can change the unlock setting. So now the OP's question makes sense. Only he should have been able to find the same post I did.
In a minute, as soon as my wife lets me borrow her phone, I'm going to test an unlock tool I know about to see if it works on 4.4.2 stock.

The dialer codes that worked on 4.1.1 to unlock the phone via the hidden menu. Does not work on 4.4.2 anymore. And being you took the ota update, there's no way of downgrading you firmware...
Sorry to tell you..
Another way is to contact AT&T by email, about unlocking the phone. Can't remember what the exact name is, but goggle search it. They'll send you the SIM code, if the phone is out of contact!!! Takes about 2-3 days when I did my skyrocket to run on TMO.

At one time, there was a free app on XDA called GalaxSim Unlock. For some reason, the developer pulled the free app download, and the only version then available was the paid version on Play. I have a copy of the free one from before it was pulled, and it works on the Captivate and the Galaxy S II, and some other galaxy phones, not sure which ones. So I tried it tonight on my wife's Note 2 which is running Stock NE5 with TWRP recovery and has the MC3 boot loader. However, the unlock failed, saying unable to read nvdata. So it's apparently a no go on this phone.

That only works if the contract the phone was in was not defaulted, and or you are the original owner of the phone.

re: sim unlock
I recently bought a soft bricked SGH-I317 (stuck on "firmware upgrade encountered and issue"). I tried flashing LJ2 firmware and got it to change to being hung on the "Samsung Note II" logo. I think this is when it changed as I was trying all sorts of flashing trying to get off the "firmware upgrade encountered an issue" screen (also Kies would not recognize that the phone was connected). Tried different recoveries and firmware without making any progress until I flashed the 4.4.2 (I317UCUCNE5) bootloader. The phone booted into Philz recovery after that. I then flashed the stock LJ2 firmware w/ LJ2 modem, sim unlocked the phone and then flashed Skynote Air 4.3 along with the 4.4.2 (NE5) modem. This is the setup that I am using on T-Mobile now with no problems except that the Knox counter is tripped. Hope this helps shed some light on the problem.
I discovered a problem with Skynote 4.3 with the 4.4.2 bootloader. If I try to charge it with the phone turned off, the phone will freeze at the empty battery symbol and requires a battery pull to get the phone to turn on. Everything else seems to work okay.

My sister sell her note 2 to me because she's gonna upgrade to samsung galaxy S5. It was an att and I'm using T-mobile.
I did check the baseband ver and It was i317UCUCNE5 (4.4.2 OTA). the question is it is safe to flash base band ver i317UCALJ2 using ODIN?
Can you do the step by step process and also links of the files and software did you use please? thanks

It's a network unlock, so you are free to use any GSM carrier. You can lock your sim card -- then a pin is required for your phone to connect to your carrier. It's the old skool method to stop unauthorized use, from the days before a lock screen pin.

I bought a SGH-I317M today off someone. It was locked to Bell Canada. I did the dumb thing by letting Kies update the firmware. And as i've read I'm pretty screwed for downgrading it. I tried unlocking it but the hidden menu didn't give me the 4th option in the network lock path. So i tried bunch of things which at one point required me installing Kies for drivers and thats when I i let it slip and update. So now I'm still searching for a method to unlock my phone. I've gotten philstouch recovery on and Skynote working. I just tried flashing the rogers_j2 modem.. hoping this will work.. you think I should just pay one of those sites or a retailer for the sim unlock ccode?

Please let me know if it works. mine is galaxy note 2 4.4.2 NE5 baseband and I've done some research and they said that if you upload your firmware thru OTA there is a possibility that it will soft brick you phone due to unknown security reason.
I'm just waiting for conformation from some one that it's safe to flash J2 modem on a NE5 OTA

in the US, if your phone is more than 6 months old and your contract is in good standing you can ask for the unlock code. I don't know if Canada is similar.

I was going to post the same question about unlocking I317 4.4.2, and found this post which is similar to what I'm looking for so just want to add to pump the question.
It's been a while but I have done unlocking for other At&t models (S3, S4) and learned that later versions don't with the option in hidden menu to unlock, and the work around is to downgrade. However with devices that have OTA updates, it's not possible to downgrade the bootloader.
Is this the same for Note 2 I317? If so, any other method available to unlock this device to use it on other GSM networks? (I just bought one and it's on Kitkat 4.4.2 UCUCNE5, and looking for unlock...)

It's only the modem that needs to be flashed. So whatever bootloader you're on doesn't matter.

I wanted to unlock my phone today. ATT website wouldn't let me do it until my contract was fufilled, so I did some web searching.
Started with 4.4.2 and NE5 baseband. Loaded original baseband via recovery, and used the debug menu to unlock the sim. After that, updated the baseband back to the latest. Tmobile sim seems to be working just fine.

I317m sim relocked after flashing 6.0.1

The problem was resolved after flashing stock, reunlock, then restore. I will report if problems comeback.
Hello,
My phone was unlocked (not sure how, bought it second hand years ago) and used it fine on 4.4 custom rom. Ive updated it onthursday to the revolution 6.0.1 (with 3.0.2 twrp, nano open gappsa) and used it fine without problems on thursday.
However, yesterday, it lost cell signal and would not reconnect. So i rebooted the phone and now it is asking me to put sim unlock pin. What is the best course of action to get unlocked 6.0.1? I couldn't find an unlock method for 6.0.1. Should i backup rom, go back to 4.4, unlock, then restore?
Thank you.

It's asking for the sim pin or network unlock pin?

SIM Network unlock pin. My modem/bootloader is I317MVLBMA3. Do you think i can safely load a 4.1.1 rom and unlock again?
If i install phone info+ and look under secret codes, it does list the code for unlocking, but if i click on it, it gives me a blank page titled "service mode" but doesn't do anything (none of the three methods of entering work under the app). Probably because it is not stock ROM?
I tried searching for stock I317MVLALJ2 ROM to downgrade easily, but it seems like the link is down. I guess ill have to use ODIN.
EDIT:
Can I use TWRP to flash http://stockroms.net/file/GalaxyNote2/SGH-I317M/I317MVLALJ2_I317MOYAALJ2_RWC.zip stock ROM? Or do I have to use ODIN? I am assuming I can as it is a zip rather than img, and as long as I flash recovery right after flashing rom, I shouldn't lose recovery either?
Thank you.

The easiest way would be to flash a stock 4.1.1 rom in Odin. I am fairly certain you can downgrade as I think I downgraded from 4.3 or 4.4.2 on a Koodo note 2 so I could use it on Rogers. If it's not possible to downgrade, Odin will stop.

Thank you for the reply. I am currently on 6.0.1, but since modem is 4.4.2 ish, i hope that's okay. I will try ODIN. The zip i mentioned above is not a TWRP flashable zip, so I guess I have to use ODIN. The thing that worries me, though, is the fact that I cannot get to the recovery mode from off. I press and hold the volume up-power- home combo, but it keeps on resetting without entering TWRP. The only way for me to enter recovery right now is using a custom rom restart menu. If I go to stock ROM, I won't be able to access the recovery .
EDIT: If I let go of the power button at a certain time while booting, it seems to go into recovery just fine.. The problem is, that timing is tricky.

For flashing a stock rom, you need download mode so don't worry about getting into recovery.
To enter stock recovery, power off and try holding power, volume up, and home. Once the phone boots, let go of power but keep holding home and volume up until you see the dead android, then let go of all buttons.

Thank you. Flashed stock using ODIN, rebooted, showed samsung logo with music (stock boot animation), then the phone is stuck on SAMSUNG logo changing colors. Stuck there for the last 10 minutes... Not sure where to go from here ..

Success. Thank you very much. So I've done the factory reset and successfully rebooted the phone. Then applied the unlock method, which seemed to have worked. Does not ask for SIM unlock pin. However, it does not seem to actually lock cellular signal. It still says 'Emergency Calls Only'. I am on Mobilicity, which used to be AWS, but now I believe is under Rogers. I know mobilicity used to take a while to connect, but I doubt that is the same now. This may be due to the old modem, so I will try updating the modem back to the 4.4 one... wish me luck
EDIT:
Without the modem update, it just connected to mobilicity !
Now the issue is, whether this phone will re-lock again once I flash 6.0.1...
Thank you very much audit13 for your live help!!
I will post back in a week or so (hopefully I remember...) whether this unlock sticks.

The 317m does not natively support was frequencies. You'll have to software enable was support.
You mean it doesn't ask for network unlock pin?

Yup. It unlocked for sure. But that is no different than what I had before updating to 6.0.1. I've used the phone without problems on Mobilicity for 2-3 years.
Mobilicity is no longer AWS, so it has no problems connecting to the network. It just takes a while, especially with the 4.1.1 modem...
Now I'm just restoring the TWRP backup that I have made on 6.0.1 to see if the unlock sticks.

The unlock stayed for my phone when I installed a custom rom.

Yes, that was the case yesterday as well. It stuck for a day, but after the cell lost the signal once (zero bars, emergency calls only), the phone got re-locked.
Now that I have restored the 6.0.1 backup, the phone is back up and running with it unlocked. Now ill will see how long this lasts.
Thank you very much for your continued support

I am having this issue now.. but the strange thing is that I've flashed to the Resurrection 6.0 rom a while back and it was working fine. Until a while ago I was pokemon hunting and all of a sudden my network died and its been asking me for a sim network pin... I was getting the intermittent network disconnect when I was on the Pokemon go app too long but it would reconnect back to the network after a short time.. not sure if it has something to do with the game app. Well, now I've downloaded the latest Resurrection rom and flashed it again doing a factory wipe but still nothing. I'm going to try and flash the modem and see if that helps.
EDIT: forgot to mention I'm on Koodo network which is also Telus, I believe. But now it wants to automatically connect to the rogers network hence I'm assuming its asking for the PIN.
(edited for grammar)

This is really strange that this happens. I've unlocked a few note 2 phones and none of them have relocked.
Did you change the csc in the phone settings to Koodo?

What's the csc you mentioned?

Csc is a carrier customization file. If you change the csc, which can be done using a stock rom, you can choose the carrier for whom the rom phone was intended. I choose Telus as a carrier because they have very little bloatware.

Provide more info, please, was your phone unlocked? When your phone was working, what firmware was you on and what service you using? Did you have Twrp installed and rooted?
Just going off what you provided, sounds like you lost unlock and possibly apns. And also use twrp to rename /system/priv-app/SprintSyncMLSvc/SprintSyncMLSvc.apk

Find full firmware from here and Odin back to full stock of whatever you had.. Reboot and try to see if the phone works.. If you have no servicve try ##72786# (SCRTN) choose yes and let it do it's thing.. This reactivates your phone and updates prl and profile. Worse case, you might have a bad sim, and need to order a new one, or see if a Sprint service center has any.. Do not go to Bestbuy as the ones they have for Sprint will not work on the Note 4. At least my local store did not have anymore for the Note 4.

If you have no servicve try ##72786# (SCRTN) choose yes and let it do it's thing.. This reactivates your phone and updates prl and profile. Worse case, you might have a bad sim, and need to order a new one, or see if a Sprint service center has any.. Do not go to Bestbuy as the ones they have for Sprint will not work on the Note 4. At least my local store did not have anymore for the Note 4.

+1 this solution.
Should take care of your problem.
Also if you get it working but still get that activation notice. If you install Twrp and use its file manager. Just rename the file i stated earlier.

By flashing stock n910p your network is get locked because you are not using sprint sim card.
Open dialer and dial ##72786# and press "yes" the phone will restart and unlock your network.then you have to make your APN settings manually.depending on your network and you will get only 3g maximum speed 4gLte will never work.
If this does not work you have to root the phone and unlock network by galaxytools app.

Does your phone shows "invalid sim" if not then your phone is already unlocked.
Follow the guide i made step by step in link below only if it shows invalid sim.
once you unlock it then you can flash any rom or stock the unlock will be permanent.

You claim LTE will not work but the N7 ports have LTE working as shown "Device Information" page. How is it that it works on the N7 port but not on stock?

Go to settings/about device/ mobile network type if it shows LTE here then it is getting real LTE signal if not then its fake LTE icon in status bar and its easy to fake it.
If you are in USA then you get high chances to get LTE work.

The "Device Information" page is a hidden setting page and accurately reflects the signal being received. The N7 ports are definitely able to receive the LTE signal on a GSM network as I am on Cricket Wireless. I have even received LTE on stock but it is very hard to do so. I've managed to play with the PRL on stock enough to get it once in a blue moon but have been unable to maintain it like the N7 ports allow me to.
