[Q] Unlocking Galaxy Note 2 (T889) on 4.3 - T-Mobile Samsung Galaxy Note II

Hello all; first post here. Very new into the android cracking scene. iPhone was stolen so a friend gave me her Note 2. I use AT&T and this phone is obviously Tmobile. I've been messing around with it and rooted the phone; using basic clockwork mod rom. Made a backup just in case things go wrong. From what I've read so far I have to downgrade the firmware to 4.1.1 or 4.1.2 then simply call that *#430... number to unlock. Before doing that I wanted to make sure I couldn't mess anything up. Do I have to change basebands/radios/frequencies/flashs/mods ANYTHING of the sort? Or do I just find the oldest t889 firmware, open up odin, (put firmware in pda) then flash it... Also, is there an easier way that I haven't stumbled across yet?
Thank you in advance for any kind of help!!

went through hours more threads. found out how to do it.
in case anyone stumbles on this thread...
downgrade to 4.2 then 4.1.1 then use the phone call method.

U can still do it on any android version. Go to serviceMode *#197328640#.
1. UMTS-1
2. DEBUG SCREEN-1
3. PHONE CONTROL -8
4. NETWORK LOCK-6
5. Perso Sha256 Info to check if its (1) meaning locked.
6. Perso Sha256 Off.
Now check step 5 again to c if its now (0) meaning Unlocked.

[Q] How to Network Unlock Galaxy S3 sgh-T999

I'm a bit of a noob, so apologies if this is in the wrong section. I've had a very difficult time finding threads that focus on those who have (stupidly!) applied the OTA 4.3 jellybean update, and what they can do to network unlock the phone. So here goes:
Samsung Galaxy SIII
SGH-T999
Android Version 4.3
Baseband Version T999UVUEMJC
Stock build. No root.
The closest step-by-step I've come across:
Remove T-Mobile SIM. Replace with ATT SIM. Reboot phone.
*#197328640# which successfully puts me into service mode.
This brings up the following menu:
MAIN MENU
[1]UMTS
[2]CDMA
[3]LTE
[4]SIM
From there its
[1]UMTS
[1] DEBUG SCREEN
[8]PHONE CONTROL
[6]NETWORK UNLOCK
[3]PERSO SHA256 OFF ...
Now, that's as far as I can get. The guide then says to go back to [6] and there should be an option, [4] NV INITIALIZZ.
This option is not there for me. (Note: at this point the PERSO SHA256 status is indeed set to SHA256_ENABLE_FLAG [0]).
Another guide suggested BACKing to the MAIN MENU and selecting option [5] run EFS SYNC() after selecting [3]PERSO SHA256 OFF.
I have done this and the screen reads: SYNC success. please reboot.
I do so, heart aflutter... only to be met with a SIM unlock PIN code entry screen.
Unlock fail.
Other threads have suggested downgrading to 4.1.1 in order for this to work and the necessary options be made available. Most of what I have read has said that attempts to downgrade from OTA 4.3 (with big brother KNOX) will result in a hard brick.
So, if you've made it this far... Has anyone figured out how to SIM unlock this particular phone running OTA 4.3 without rooting/downgrading?
If there is a more suitable thread discussing SIII's that are running 4.3 please direct me there.
Many thanks!
You could try and flash a 4.1.1 Modem. After that, try the above process.
Note - In that process, you are required to be super patient at each step.

Appreciate the response.
Yes, most of what I have come across has indicated that I would need to get 4.1.1 by hook or by crook in order to network unlock the phone, having upgraded to 4.3.
I have some experience fiddling with such things, but many posts have also indicated that, with the new KNOX package in tow, backing down from 4.3 will hard brick this device. I am hoping that, with access to Service Mode, someone will discover a way to network unlock without root/flashing.
Thanks again!
Are you Rooted ? If so flashing the LJC modem from Doc's thread won't brick your device.

The phone is not currently rooted, no. Most rooting instructions I've seen are for 4.1.1 or 4.1.2. My guess is I'm going to have to root to unlock...
Could you direct me to instructions for rooting OTA 4.3?
Again, many thanks for taking the time to help.

Follow these. Effectively Flash Custom Rom using ODIN then flash SuperUser Zip.

Well, no luck. Followed all the directions I could (provided by some awesome contributors including Doc) including:
1)Rooting using the aforementioned method and installing 4.3 with SU and no KNOX. Then just flashing stock modem 4.1.1 UVDLJC, in order to reveal the [4] NV INITIALIZZ option that is not present in Servicemode on jellybean 4.3 firmware.
--- This resulted in very slowed down system with no WiFi capability and no startup or shutdown sounds. Logging into Servicemode just resulted in a blank screen that said Servicemode.
--- Ultimately had to emergency restore firmware via KIES. (Thanks to reading a post by Doc on another thread). This got me up and running again.
2) Rooting using aforementioned method. And searching for stock 4.1.1 firmware in order to downgrade...
--- This has proven to be impossible. I can not find stock 4.1.1 anywhere. All links that have turned up have either been dead hotfile.com links or corrupted .zip files.
--- Additionally, I have been informed that once you upgrade to 4.3 OTA it is IMPOSSIBLE to flash an earlier firmware using ODIN. (Is is possible using CWM perhaps?)
In the end, it appears that the jellybean 4.3 OTA update currently has the community stumped as to how to unlock the SGH-T999 for use on another network with your only option to either convince T-Mobile to give you an unlock code or ordering one online. (And I've read of too many folks getting bogus codes ordering online...)
Still having fun trying, and its very cool to see all the hard work and info that folks like Doc are compiling on here. Maybe somebody is on the way to cracking this nut!!!

So after all that, what is your current Rom and Firmware ? Can you try Root66 of 4.2 Rom ? Doc has Re-Hosted with mirrors.
I followed cLogic's guide that you linked to above and am running 4.3 rooted w/o Knox garbage.
Ended up getting phone network unlocked at a local hole in the wall phone shoppe. Figured it was worth a couple extra bucks to have it unlocked face to face in case code didn't work rather than fish out a reputable online source on my own.
Will be curious to compare its power usage to stock 4.3. Phone is working well, although it seems I will have to play with the APN settings as I am unable to send MMS messages... hmmm. Any advice off the top of your head?
I'd given root66 a try and also gave Doc's reposts another shot, but no dice.
So the sum of my endeavors are as follows:
1) If you want to network unlock your galaxy s3 on your own, DO NOT upgrade to jellybean 4.3 OTA until you do. It does not seem anyone has figured a way to ala ServiceMode in 4.1.1 yet.
2) If you have upgraded to 4.3 OTA you can use cLogic's guide linked to above to root your phone sans Knox.
3) If you have already upgraded to 4.3 OTA and want your phone network unlocked, you will have to pay to have it factory unlocked.
4) XDA is the bomb.
UPDATE:
Looks like the MMS messages I was trying to send finally went through... it just took an inordinately long time for them to do so.. not sure why yet.
Of dubious help to the OP, who had his phone commercially unlocked, but for others reading this thread or the OP's curiosity.. the 4.3 update has caused all kinds of grief. Amongst various bugs and battery drain issues, 4.3 has changed dialer codes or shuffled menus around. I can confirm the same results as the OP up to the point where he found that the initialize NV menu missing.
To progress further, I found that I needed:
An active SIM from a different carrier, with said SIM needing to be the phone throughout. This is in contrast to the previous method that worked without a SIM in the phone during the unlock procedure. I successfully unlocked a Note 2 with 4.3 using the steps in this techbeasts.com post.
And was successful with a 4.3 S4 using a slight variation (no NV initialize menu!.. back.. key input.. 1.. back). Both phones were M (Canadian) models.​
Reading between the lines of various reports in addition to first hand experience implies that there may be several different carrier specific dodges being employed here. Playing musical chairs with the missing menu items that now have different dialer codes, are now found on hidden sub menus (key input = 1) or in back up files.
The commercial unlock guys are using proprietary tools such as Samsung tool v 16.8. Which usually seem to be database based factory unlocks fetched (or calculated?) from their servers.
.
since this worked on a note2, would it work on a sgs3 t999 that is already on 4.3?

well i dont know if it will work for me because my t999 is running cyanogenmod 12.1
The phone must be running stock 4.1.1 in order to sim unlock using the free method. Once the phone is on a 4.3 or newer bootloader, sim unlocking must be done using a code specific to the phone's imei. In order to enter the unlock code, the phone must be running a stock ROM or possibly a custom ROM based on a tw kernel.

So, I previously rooted my s3. It is locked to tmobile. Then I unrooted and tried to unlock it but of course after 4.3 update (LUVUBOH1 Big mistake I see! I tried to flash a different 4.3 stock baseband just to make sure I flashed stock rom but odin failed. I kept trying and even updated odin, but no dice. Any ideas??
Do you have an unlock code? If not, you'll have to buy an unlock code and enter the code while running a stock ROM.

Yes, I did purchase an unlock code. I'm going to try a different sim. I THINK I'm running stock rom 4.3 LUVUBOH1.
When you insert a non T-Mobile sim, you're not prompted to enter a network unlock code?

basic question about unlocked At&t note 2

So, I have an i317 At&t note 2. It was originally on 4.3, but I wanted to unlock it. I followed some forum posts and reverted back to 4.1 and was able to unlock it. It worked with a tmobile sim on 4.1.1, but now when I try to update it (either through Kies or through update on phone), it updates but then gets stuck at the samsung galaxy note 2 display. I found another forum post (thanks, but cant find thread atm ) which had a file to download. I installed that using Odin, but that only got it to work on 4.1.1.
I guess my question is I have the note 2 running on 4.1.1 that I factory unlocked, but now it wont let me update. How do I get 4.3 on it? Thanks
Ok there's plenty of 4.3 Rom's in the development section...
Just have to search for them!
Q: »»»»
Is it rooted?
Do you have a custom recovery installed?
Are you sure your familiar flashing Rom's?
Etc etc etc......

It is not rooted. All I have done to it is downgrade it to 4.1.1, then unlocked it. Is there a stock ROM. I want to be able to go into settings -> about phone -> and update it that way whenever a new version comes out and not have to install custom ROMS. Is that possible?
No, I don't have a custom recovery installed and I am not familiar with flashing Rom's.
I thought I could downgrade to 4.1.1, unlock, then update to the newest stock version through updates in the phone, but thats not the way it works when you unlock the note 2??
thanks
Pardon me if I sound ignorant. I am new to android (switched over from apple a month ago). The note 2 had 4.3 on it. I followed thread
http://forum.xda-developers.com/showthread.php?t=2014982
to unlock my phone, but had to revert back to 4.1.1 in order to do so. I followed posting
http://wccftech.com/guide-to-downgrade-firmware-on-samsung-galaxy-devices/
to downgrade to 4.1.1. That went successfully and I successfully unlocked the note and all was good. It was running 4.1.1 and I was using a tmobile sim. I went to updates through settings on the phone and tried to update. After that point, it just boots up to "samsung galaxy note 2" screen. I used Odin3 v3.07 to reinstall 4.1.1 and its working again.
I would ideally like to be able to go through software updates on the phone to update it and not need to use custom roms. Is the problem I am trying to update from 4.1.1 to 4.3 and I need to manually update to 4.2.x first, then go to 4.3?
I don't understand why unlocking it prevents me from updating from 4.1.1. I have tried through the phone and through Kies, which keeps getting an error. Does this make sense? Am i doing something wrong? The phone is originally At&t. Do I need an At&t sim inserted to update through the phone?
thanks for all the help and once again, sorry if these questions seems elementary. I am reading through forum posts and trying to understand what all this means. I'm not sure what rooting or flashing means and how flashing is different then unlocking.

What is unclear is why ware you trying unlock it, what carrier it was on and what carrier you are changing to,
You're asking if it needs an ATT SIM to update, so I'm lost on what carrier it was on.
The original carrier is at&t. I unlocked it and now am using a tmobile sim. However, when I got to settings and check for updates, it says "checking at&t servers for updates". So it is working for tmobile now, but only on 4.1.1. I don't mind downloading custom roms (and definitely appreciate the work), but I would like the option to not have to.
And when I boot up the phone, even though the network says tmobile, it shows at&t start up screen when it boots up into 4.1.1. Which is why u was thinking maybe the reason it won't do updates through the phone is cause there is no at&t sim inserted when it is "checking at&t server for updates"

Well, over my head here. I think you have figured out technically why it's not working.
You are operating on a T-mobile network and you will not see ATT servers.
Even though it's says you are on T-mobile is anything working? Like texting, surfing or cell calls?
I would imagine texting is not since the config should be pointing at ATT servers.
I would think you should be running one of these factory images

I personally do not know if the T-889 is close to the ATT Note 2 model.
You may want to bounce over to this forum
http://forum.xda-developers.com/note-2-tmobile
See if anyone has attempted what you are doing.
In my mind you need to flash a T-mobile image to do what you want.
I am not suggesting you do this, I am merely giving you an opinion.
You may want to investigate this custom ROM

Yeah, I dunno. It's an i317 on at&t. And it was definitely on tmobile cause it let me send text messages and it showed "tmobile" across the top as well as their 4g icon.
All I was trying to do was unlock my at&t note 2. Now its unlocked but stuck to 4.1.1. Lol

HOW TO: How I SIM unlocked my N7105, Includes downgrading to 4.1.1 and 4.1.2 insts

How to SIM unlock and/or roll back firmware on Samsung Note 2 N7105.
This is how I did it. It worked for me. That's all I can say. It may or may not work for you. I'm no 'expert' so I can't answer any tech question. I found this by trial and error. None fatal. ( So far) I will take it for granted you know how to Root and use Odin. I'm also assuming you have installed the Samsung USB Drivers.
http://uploaded.net/file/xdloq4jw
If you are using one machine to do this remember to disable Kies before using Odin.
My phone was updated to 4.3 using Kies. I did this on my laptop as I didn't want Kies messing up anything on my computer that I was going to use for the rest of the process.
So stating with a stock phone.
Using Odin
http://uploaded.net/file/o2xcp01n
I rooted my Phone with
CF-Root
http://download.chainfire.eu/255/CF-Root/CF-Auto-Root/CF-Auto-Root-t0lte-t0ltexx-gtn7105.zip
I then downloaded SuperSu from the market and ran that. It runs a fix to stop Knox.
I then installed ES File Explorer from the market.
Then I downloaded My Phone Explorer. I like this program and use it a lot.
http://www.fjsoft.at/en/
Using ES I backed up my EFS folder to my Sd Card
Using MyPhoneExplorer I backed it up again to my computer.
Better safe than sorry.
I then used Odin again to install the 4.1.1 Firmware.
I got it from here. There's 4.1.2 there as well for those that asked.
http://www.sammobile.com/firmwares/1/?model=GT-N7105&pcode=EVR#firmware
I then installed 4.1.1 by unzipping the file and using Odin.
I then use CF-Root again.
Using the *#Codes as below
Step 1. Insert a SIM on your Note 2, you should find the familiar “SIM network unlock PIN” window.
Step 2. Dial “*#197328640#” on your Note 2 to enter special menus.
Step 3. Choose “UMTS”.
Step 4. Next choose “Debug screen”.
Step 5. Choose “Phone Control”.
Step 6. Choose “Network Lock”.
Step 7. Choose “Perso SHA256 OFF” and wait about 30 seconds.
Step 8. Press the Menu button then choose “Back”.
Step 9. Choose “NW Lock NV Data Initiallize” and wait about 1 minute. *Then reboot your Note 2.
Step 10. Once rebooted, you should no longer get the Network Lock window any more and you should be able to get signal and data. *If you have trouble getting 3G/HSPA+ data, try setting the APN to your carrier’s settings although it should set automatically.
I did try this using 4.1.2 but Step 7 was missing.
I then updated back to 4.3 using Kies on the laptop and then CF-Root again through Odin on my computer. Fixing Knox by re downloading SuperSU and running that.
One SIM unlocked phone.
I then used Titanium to freeze all the Samsung and Google stuff I didn't want and also froze Knox.
MY phone is running stable and good. Auto update though says it has been modified so now it will not OTA. Which isn't a bad thing.
Thank you to the respective developers of the software I used.
I hope this helps others.

MY phone is running stable and good. Auto update though says it has been modified so now it will not OTA. Which isn't a bad thing.
Thank you to the respective developers of the software I used.
I hope this helps others.

I got the same problem,after updating to 4.3 version my phone asking for Sim network unlock PIN.
You mean flashing 4.1.1 from 4.3 got no failure?
Currently downloading 4.1.1 version..after attempting to flash 4.1.2 it failed in Odin,due to a new bootloader
Edit:
Confirmed I successfully flashed 4.1.1 and successfully unlock network.
Tnx dude!

Absolutely no idea mate. I only tried it on my phone.
ive been looking for this
im having the same problem and hopefully this fixes it.
but about the updating to 4.3 using Kies, wont it trigger the SIM network Unlock Code again?
Hi, what android PDA did you have before doing the downgrade. I have read some posts that say that you can not downgrade if you have MK4 or later... I have a Galaxy note 2 GT-N7100 and I would like to test what you did with mine, but I'm not sure if its possible

All I can comment on is how I did it on mine. I don't have any other phone. Sorry.
Maybe try the UK one that I used. Once it's SIM unlocked you can put a local to you ROM on.

Hi,
I followed the instructions properly. I rooted my 4.3 with CF auto root, and then I tried to flash the 4.1.1 firmware onto my phone.
Now it is stuck at the boot screen, and I'm so shocked because I did everything correctly.
I can still get to "ODIN Mode" by holding volume down, home and power, and it says:
Current Binary: Custom
System Status: Custom
Knox warranty void: 1
What have I done wrong?
Thank you.
help me !
i have a Note 2 N7105.i did the exact steps.on the notification bar, i can see that i have signal, the phone is unlocked, but still, i cant use the network. it says NOT REGISTERED ON NETWORK. what do you think is the problem ?

I must say.... you are my SUPER STAR..... I have search everywhere and looked every corner of the website..... apart for paying around £20 to 40 to unlock the phone from someone... you have made my day.... I have been trying to unloack a phone that I have bought from ebay... it was locked to EE network in UK, your way of downgrading the firmware to 4.1.1 and use the code “*#197328640#” had worked... the phone has been upgraded wot 4.3 Jellybean, and the code does not work at all. However after down graded to 4.1.1 (as you have done) , I was able to use the code “*#197328640#” and unlock the phone, then I upgrade it back to 4.3 and now doing a firmware upgrade to 4.4..... the network block has ceased... so I guess the phone is now completely utterly unlocked forever....REALLY Thanks to your logical trial and error...
I must say, it took me some trial and error to reinstall the stock ROM, whick I had to use Philz recovery to completely clean up the device before I reinstall the stock rom.....
Any thanks again, and when I get a chance, I'll post my steps which had worked.
Cheers Mate,
Dave
Am glad to hear that
works great
Big thanks to BorgCymru for the how-to.
Just got a n7105 that was locked on EE/Orange (UK) that had KitKat 4.4.2 installed. Followed all the instructions but used cwmrecovery (to make backup rom) and it worked great for me. Tested with tesco, 3, o2 sim and all work.
Only thing to add that after installing firmware 4.1.1, the phone went to reboot but the screen became locked on the 'Samsung' logo. I removed the battery and booted into recovery to wipe partition and wipe cache. Rebooted and all was fine.
i been having issues unlocking with running 4.4.2 indeed to downgrade was the correct step, i am now unlocked
I know you posted the original post a while back, however I purchased a note 2 7105t off eBay and it was locked to Vodafone Australia. I actually got a code off their unlocking site and of course it did not work. I then contacted their customer service and waited 4 days for a call back with a unlock code and master reset code, once again did not work and I was told to take it to a Vodafone shop and they will send it away. One again, brick wall, as the shop said, "have you a proof of purchase from Vodafone". Nope I do not so they refused to send away and told me I was,"stuck with Vodafone".
Now I want to thank you for assisting me in unlocking my galaxy note N7105T 4.2.2 with your information. It worked like a charm.
The only question I have is if I now put an update firmware from 4.1.1 will the lock come back on? I see here a couple of members said they were fine, can I get verification on this please.
Hi Tamate. Once you unlocked it is permanent.

No so... Did that way back, and last it while travelling, it locked itself! Still trying to find a way to unlock it (I'm now on Marshmallow!) Afraid downgrade back to 4.1.1 will do more damage (bricking the phone for good!)
BTW, how can I tell if my bootloader ever got upgraded?

How to Unlock T-Mobile Galaxy Note 2 any Firmware Root Required

There seems to be a lot of confusion on how to unlock the T-Mobile note 2. This unlock is dependent on what modem you have not necessarily the rom or software that is on the phone. However i HIGHLY RECOMMEND you use a stock rom for this unlock procedure. this tutorial assumes you already have rooted your device, and a custom recovery installed. Do that before following this guide
I am not responsible to anything that happens to your device.
You must be rooted on a custom recovery for this guide to work.
This guide is only for the t-mobile note 2 ​
You will lose 4GLTE when you downgrade your modem don't be alarmed it will come back when we update the modem at the end of the guide
1. First you need to downgrade your modem
UVALJ1_Modem
You will download the flash able zip and flash it via recovery.
2. Reboot your device and then follow these instructions.
http://www.youtube.com/watch?v=-cmiEZcw1z8
T-Mobile Users might have to downgrade to unlock your device. I have listed all the phones and providers that worked. If you have a different carrier and a different model, and if it works please leave a comment on my YouTube video! (http://www.youtube.com/watch?v=-cmiEZcw1z8) Thanks.

3. After you reboot verify that your device is unlocked, i had a blank att laying around if it does not ask you for an unlock code it should be good
4. Reboot Into recovery and re-flash the new modem.

Congratulations you have now unlocked your Note 2 for use with any carrier. the main point of this guide was to explain it all in one post. i hope this answered any questions that people were having about unlocking this phone.
Things to note:

Use twrp / cwm and backup your cm10.2. Wipe data / system / dalvik / cache. Install a stock based touchwiz rom ( I used jedi x1 ... but whatever you use CHECK THE MD5!! ). Downgrade modem and follow the steps. After successful unlock, restore your backup.

Blacklisted??
***If this question is not allowed I'm sorry***
I'm curious does this unlock it from the Blacklist?
I have a Note 2 that is Blacklisted, thats why i'm asking.
Thanks

There are two ways to get a blacklisted device running. One is to get the phone legit again by getting the blacklisting lifted if the original owner was a deadbeat. I recommend this though it can be *difficult*.
The other is to fraudulently change the IMEI ("IMEI Repair") which is not OK to discuss here. This is the only option for people who possess stolen phones and don't mind being criminals. Those people have no place in our community.
I suggest approaching T Mobile and asking them why the device was blacklisted. After that you will be able to discern your next course of action.
Apparently this doesn't work if you are on a 4.4 rom even with the suggested modem. I don't currently have a 4.3 or lower rom available to try this with. Just and FYI
I was able to get my phone unlocked. So my downgrade from 4.4 Rom and install a 4.3 touchwiz Rom with the modem listed in the first post. Thank you so much for this!!
Good to know about the KK vs JB nuances. Thanks.

Yep. Thanks, Chavist. I had been struggling with this for several years till you finally put the pieces together for me. Once I used the 4.3 ROM and the ...J1 modem, it worked like a champ!
I know this is a very old thread. However, I just replaced the motherboard on my T-Mobile Note II and brought it back to life. Does anyone have the old modem flashable file for download? All the links above aren't working. Thanks in advance!
Disregard, found it here in case anyone else needs it.

How to unlock the Samsung Note 2 CANADA (SGH-I317M)

Hello! Now, I am a new member, And solely for one reason..
I AM UNABLE TO FIND A MODEM FLASH FOR 4.1.1 BASEBAND I317MVLUDNH2
Now, I have searched EVERYWHERE, and, all the Rom's are for the I317, and if it is for the I317M, I am unable to download for some odd reason.
Now, Here are the links i've searched through (Just incase I missed something)

http://forum.xda-developers.com/showthread.php?t=2275844
http://forum.xda-developers.com/showthread.php?t=2590452 This may be the answer.. Tho I've heard using a Flash not made for your Modem can brick your phone..

http://android.stackexchange.com/qu...317-att-samsung-galaxy-note-2-on-jelly-bean-4 (links back to first link)
So, I am basically out of ideas. All i want to do is DOWNGRADE to 4.1.1, unlock the phone through the hidden menu, Then go back to 4.4.2. (Since i got the phone from a friend, and am currently using a rogers [Well, More of a Petro-Canada] Sim...)
So, Would I be okay using that Rogers flash? With Phrilz OR TWRP?? Or how would i go about this???
FIGURED IT OUT!!!
Okay, Here is a rundown on how to do it:
1. First download TWRP https://twrp.me/Devices/
2. Download the ROGERS Modem firmware http://d-h.st/rJq
3. Download Odinhttp://androidhost.org/get/PVAIv
4. Enable USB Developer Mode
5. Put the Phone into Odin download mode (Shutdown. Hold down Power+Volume Dwn+home. When the Bootsplash shows, Let go of Power button. Press Volume Up
6. Open Odin on your computer, browse to the TWRP .img (if you haven't already unzipped it, Do so) In the PDA section
7. Hit start, Wait till it is finished
8. Now, Open the phone directory in your windows manager thats built into the OS.
9. Drag the .zip into your main phone directory ( / )
10. Shutdown the phone, Hold power+Volume Up +home. Do it until bootsplash is done. (same as step 5)
11. In TWRP, select backup, then backup the MODEM folder. (I honestly forgot this step, If you have. There is links for the original baseband.)
12. Once that is backed up, You can either upload it to your desktop (i'd recommend doing that) Then, Open install, Browse for the .zip for the MODEM, then flash.
13. The system will reboot back into TWRP, just pull the battery out, and insert it back in, boot up the phone.
14. Type in your dial: *#197328640#, UMTS, DEBUG SCREEN, PHONE CONTROL, NETWORK LOCK, Then select option 4. Reboot phone
The simcard should now work!! Now, You can either install the old firmware you backed up, or just leave it.
New firmware for 4.4.2 Incase anyone Needs it: http://www.sammobile.com/firmwares/database/SGH-I317M/
Hopefully this helps anyone. It took me 5 hours to find out all this info (because the phone is a I317M, Not the non "m" version)
THANKYOU FOR ALL THE WORK OTHERS DID FOR ANY OF THESE PROGRAMS USED!!!!
THIS DOES NOT WORK ON CUSTOM ROM!!! You must have the original Stock rom, or atleast something close with the samsung stock dialer, as the code only works on those.
Thank you for your detail instructions. Recently I got a used a SGH-I317M locked to Rogers. It has firmware 4.4.2. Will it be safe to follow your instructions to flash the 4.1.1 Rogers modem only, do unlock, and then restore to the original 4.4.2 modem with twrp?
Thanks,
Howard

Yes that should work (So sorry for the late reply, I haven't been on this site since I made the post) Just make sure to backup before you do anything incase it does happen to screw up Just remember to select that last link (sammobile) and get the firmware FOR YOUR NEW CARRIER, not the old one.
I need to unlock my At&T note 2 but it is now running 5.1.1 Bliss Pop. I tried that code but of course it wont work.
I sent the IMEI number and paid to have it unlocked but the company I sent the money to said they could not unlock it either.
What would I have to do to this phone to unlock it. I am in Cananda this week and want to use this PetroCan sim card I paid for.
Thanks

Okay, this is quite simple, install TWRP as usual, but backup the MODEM you have right now for 5.1.1, Then follow through the instructions, and install the MODEM you backed up after. That shoould work, if not, try to find modems for the phone for 5.1.1, But usually, (if my computer knowledge is correct) a new OS shoould support and older modem, so, you can try 5.1.1 with a 4.4.2 modem.

I tried the rogers modem and the *#197328640# did not work.
Any other modem files you can suggest?
It appears that I have to the load original stock rom but I also read that is not possible either.

Huh.. Thats honestly really weird, It should work. Did you check the "about" section of your phone to make sure it properly installed the 4.1.1 modem?

your second link modem
it has tons of popups and when its not trying to open new windows and ask for browser access etc it downloads a "flash file" your 1.4mb download is a exe and puts up a warning.
since samsung removed the menu entery they left in by mistake on early 4.1x releases there is no way this ork to do anything but install malware and trojans from your site.

You can extract the modem from the stock 4.1.2 ROM or you can flash the entire stock ROM in Odin, unlock, and flash back to the latest stock ROM.
