I bought the T889 on release to unlock and use on straight talk, with the straight talk AT&T micro sim. (I'm not cutting down a straight talk T-mobile sim) I rooted my phone using these steps. (galaxynote2root.com/galaxy-note-2-root/how-to-root-galaxy-note-2-easiest-method/) ((I'm too new to post links)) The phone rooted like a charm. I tried a sim unlock app that needed root to use, but apparently the app only works with certain chipsets. Contacted support for the sim unlock app and they told me I'd have to pay a service to unlock the phone for me. T-mobile only gives you the unlock if you've been a customer for over 60 days. Playing with the CWM I was able to unroot the phone. I am unable to figure out how to get rid of CWM to have the phone get OTA updates. Any assistance would be greatly appreciated. Mr. or Mrs. moderator, I apologize if i put this in the wrong place, I'm new to the forum scene.
This is interesting.
Does this mean I can take my note 2 and unlock it, then give it to my cousin on at&t and she can use Lte?

my understanding is that the t-mobile version was made with LTE locked, but I'm clearly not an expert. I've read that the phone includes the radio to pick up LTE bands, but that you would have to do something to unlock the feature. However, the phone should work exactly the same as it would on T-mobile, with no other changes, aside from unlocking the sim.

It does have a radio for the LTE bands. It is locked upon purchase. I am not certain, but perharps using the USSD codes to get into radio choices may be simple enough... but I am by no means an expert. Try *#*#4636#*#* to change cellular radios

You can flash Chainfire's CF-Auto-Root. It installs SuperSU and stock recovery. Then you can just use the Superuser app to unroot.

Everything I've read implies it would take a serious firmware update to enable LTE, so I don't think I'd count on a solution soon. That sure would be cool though.
Hello XDA and Happy New Year!
I have a rooted Note II sgh-i317m locked to Bell Mobility. I would like to use it with another carrier. I have asked one source for an unlock code, and verified that he received the correct IMEI for the phone, but he said he was unable to get one. I have tried "00000000" but that doesn't work.
I rooted it to try GalaxSim Unlock from the Play store. GalaxSim says it is incompatible with this device. When I click "show details" I get "undefined" for IMEI, Sim Lock status, Product code, Serial Number, and all the rest of the fields. (I believe the app is using the android SDK to query the device for these settings and getting nulls.)
Rooting was a piece of cake with Odin, but how do I unlock my phone?

My root method was from galaxynote2root.com; it apparently doesn't touch the firmware.

HELP! I have a note 2 from rogers, i recently tried to do the service mode unlock. (#*197328640#) followed the instructions but i was missing the option 4 nv data. found out later that it was 4.1.1 i had 4.1.2. So got impatient took it to the local cell unlocker fella. He ran into trouble with entering the unlock code then attempted a process that reversed what i did and entered the code, this seemed to work the unlock with the code was successful. Or so it seemed until i inserted my telus sim card then my $780 dollar phone that i just paid cash 2 days ago wont accept the sim or any other including rogers. I tried rooting and i put 4.1.1 back on this got me to the point where it will accept a rogers sim but data will only run edge and call out if i set it to gsm only in network settings this is the only way it will accept a rogers sim only
unlocked
me too , i can not unlock my note 2 canada sgh-í7m

No.
i know it a little late but if there are still people reading this today, well... this worked for me, and you need to be on 4.1.x variant of the note 2 i317/m rom.
I was initially on a 4.4.2 Koodo variant and downgraded it to a 4.1.1 Bell variant before i was able to successfully unlock the phone, since anything after 4.1.x that method is blocked/unavailable/patched. After i was done, my Videotron sim card was accepted and LTE is working flawlessly. Flashing Bells 4.4.2 rom posed no issues and phone was back to normal. Software updates were being checked normally (even tho no official lollipop will ever come from Samsung... but just saying) and nothing was acting out of the ordinary.
only problem is (but shouldn't really be anymore) that your KNOX counter will trip and will stay stuck at 1 due to some hardware thingy being physically changed. This is because of the Security enhancements being violated when downgrading from 4.4.x to 4.1.x. (kitkat to jellybean is a big nono to the SE, but the other way around or kitkat to kitkat is fine)
if any issues or questing feel free to ask GL
Here's the issue. I purchased the At&t s3 (SGH-I747) last year. Long story short, I wanted to go to T-Mobile prepaid with the same phone.
I purchased the SIM activation kit for $10, popped my SIM in and it worked!
Before I put the SIM in it though, I paid for an unlock code. I still have the code.
No 'Network Unlock' screen.
No prompt for my unlock code.
I am getting H+ speeds with the at&t s3 on T-Mobile prepaid without doing ANYTHING.
My question is:
Why cant I get to the unlock screen? I have tried to dial "#7465625*638*# for the prompt to popup and NOTHING.
Can someone tell me...
1. Can I flash a T-mobile rom to this phone? (every time i try I get a build.prop error, even after changing the model to the T999 and all that jazz),
so I can't install a T-Mo rom?
2. Do I have to flash a modem/radio or anything else like that?
3. Or, should I just continue to flash At&t Roms with the t-mo prepaid sim?
I have searched for a while now, and noone has my problem. I never expected to just switch sim's and it would work, so ANY help would be appreciated.
Thanks!

since your device is still an AT&T branded Galaxy S III (SGH-i747), you must keep with ROMs designed for that phone. flashing T-Mobile branded Galaxy S III (SGH-T999) ROMs will brick your device, same thing goes for flashing modems.
just because your SIM and Carrier is now T-Mobile, doesn't mean your phone is.

Wrong. Flashing an rom meant for the AT&T variant of the S3 on a T-Mobile variant S3 and vice versa will not brick the device. APN setting may get messed up and you have to enter them manually but it will not brick the device. Flashing a ROM for the international S3 on a U.S. variant of the S3 and vice versa will brick the device.
I wouldn't recommend flashing modems between the variants of S3s, that may or may not brick the device but wouldn't try it.

Hello.
If you have signal then why are you trying to use the code? It is unlocked already!
im not an expert but this is what i know from reading a lot:
1.- I installed a t-mobile (t999) rom modified to work in a att s3 (i747), i think you can flash a any rom from the t999 section (i am not sure about this)
2.- Do NOT try to install a modem from t-mobile or you will hard brick your phone.
3.- Thats a good idea, do it and let me know if it works.
I used this files to convert an i747 to a t999 http://forum.xda-developers.com/showthread.php?t=1771021&page=25 (read from post #246) so now i use customs roms for the t999 i did it because where i live do not have good signal, was stuck at edge and with those files now i have 3g signal.
Btw, i am in the $30 prepaid t mo plan.

That is not true. Before following these instructions ( http://forum.xda-developers.com/showthread.php?t=1771021&page=25 ) I could NOT install any t-mo rom as CWM verifies the make/model before installing the rom.
Hence, me having the 'installation cannot continue' build.prop=d2att.
So, now AFTER flashing the 4 files, I was able to install 3 different T-Mobile ROMS. XTREMEPERIA ( http://forum.xda-developers.com/showthread.php?t=2199018 ) was the only one that is giving me 4G. I know, I know, its all in the APN settings, but this is the only one that gave me truly 4G speeds with a T-Mo sim.

You are right, clockworkmod (Rom Manager) does verify, however if you select
and flash the Tmobile T999 recovery image when flashing clockworkmod recovery
all is fine.
Another thing, if you have a unlocked i747 and flash any Tmobile cwm zip file rom as
soon as it reboots and you check the network in the phones settings it will display
"T-Mobile US" and will work properly without the need of any other files or conversions.
However the Unlocked I747 will never work with Tmobile's 3G or 4G networks.

You need to specify that you are using an engineering image that T-Mobile used on the 747 before the T-999 was available to test the device. In general if you flash a T-Mobile radio image to a 747, you risk losing calls and data at minimum and a hard brick at worst. It is imperative to make sure to point out that it only works with THAT engineering set.

Ahh...gotcha. Thats what it states in THAT OP, I just thought that once that build was on the phone, from that point on, any T-Mo anything would work. I did have the watermark on my wallpaper, but everything else said 't-mobile'.
But, yes in general, if you flash TMO onto AT&T, there be dragons.
Thanks all, and happy flashing!
Even with that configuration, the only thing T-Mobile you can flash is recovery and custom ROMs. A T-999 baseband or boot loader could very well cause a brick. Its a dangerous hack because it has everyone confused. For all intents and purposes, it is 747 software with T-Mobile's AWS capability. In fact it doesn't even seem to have DC-HSPA, only HSPA+ (21mbps versus 42). It has the benefit of supporting T-Mo LTE though.
Awesome

It doesn't make sense for T-Mobile to refarm their LTE. The 1700 AWS band is the most efficient spectrum they currently own and the AWS spectrum is going to be the most compatible across LTE networks. T-Mobile has pretty much no chance of ever getting the 700MHz that at&t and Verizon are using.

The Sprint variant is a CDMA phone. I don't think it will work on GSM networks, if that's what you're trying to.

im looking to sim unlock the S4 mini L520 (sprint).
after i follow one of the unlocking guide i can access gsm,umts network setting, apn setting and many other settings.
so i think it just need a software like S4 L720 to unlock it.
i try the same software but shows DONE AND REBOOTS THE PHONE BUT THE PHONE SHOWS INVALID SIM.
BECAUSE THE SOFTWARE WORK WITH FIRST MODEMS NOT WITH THE LAST NE3 OF THE L520 BUT IM NOT FINDING ANY MODEM.
I'd be surprised if it's possible to get a GSM SIM to be recognized in a CDMA phone.
There are firmwares with old modem on sammobile, but unfortunately since the phone is already running kitkat, downgrading is impossible afaik.

but there is just the mk2,the phone was released on may 2013, so there is an older modem a think,
so i just flash the modem, maybe i can unlock it and than reflash the new modem again.

Do you have any news about downgrading?
