I unlocked a Galaxy S4 SGH-I337 FROM ATT I am using Tmobile services.
My question is can I install a Stock ROM from TMobile instead of having the ATT one?
I like the Wifi Calling and Tethering option.
I can tell you... But I have a LOT of readers who want to know how to do what you have already done! How did you SIM unlock your SGH-I337? There is a published method for AT&T and TMo that seems to no longer work on the AT&T variant.
OK.. I won't hold you hostage, but I really would like to know!
For the flash to stock, just head over here http://forum.xda-developers.com/showthread.php?t=2267895
Follow the instructions and that will re-flash T-Mobile stock everything.

Yes. But also check this thread. The AT&T boot loader is locked and may require Loki Doki patch when you are done.

.... I may be wrong here, but since when has it been OK to Odin different carrier's stock .tars? Flashable CWM zips yes, but the bone stock tar with modem, baseband, etc?
Also, being that you have TMO service and an ATT device; flashing a TMO ROM with WiFi calling should work; just use an ATT kernel and the Loki patch. Personally, I'd flash the rooted stock MDL or a custom TouchWiz via CWM or whatever recovery you happen to use and not use Odin.

Since wjenmisnit OK to do it differently?
It is only OK to do when you know what you are doing. In this case the hardware is absolutely identical. You're not going to be using AT&Ts baseband firmware on the T-Mobile network are you? Good luck with that.

i have the i337 ATT and I am using a Tmobile sim card. Just youtube "unlock galaxy s4 AT&T". There are plenty of videos that use a secret menu to unlock the phone.
Free and instant
I also have AT&T i337 unlocked BUT
I also have AT&T i337 unlocked BUT when I try to use it with MetroPCS (same tower as T-Mobile - companies now merged) I can't get anything but Edge network where on my MetroPCS-supplied phone I get 4G (LTE only rarely) in the same areas. Edge network is ridiculous - can't even load a standard webpage- forget about watching a video! ookla =0.01mps!
So I have an unusable rooted, unlocked S4.
I've tried various APN settings to no avail... Thought I would try liquidsmooth ROM, or any ROM that works on both AT&T and T-Mobile... I assume T-Mobile /MetroPCS would react the same. And I am on a pay as you go plan that is similar to T-Mobile's s. I could easily switch to them if not...
Questions:
Has anyone any advice that could help?
Does anyone know if T-Mobile requires a "pairing" of sim card with phone's IMEI as MetroPCS does? (big pain in the butt)
I've done the same thing flashed roms, Modems, To my luck nothing, I did filing that since I repaired the imei, That is when the problem started. Also to does not tie imei to sims. Did you repair imei

Easy free Sim unlock
Just wanted to point out that if you know someone who has AT&T service they can unlock your phone for free My girlfriend did it for me on their website and it took 24 hours for them to send an email with the unlock code. Just thought i should share that. Up next getting this t-mobile rom onto my 32gb i337 at 4.4.2 with NB1. I hate everything AT&T and God is this phone bloated!

To be honest i can't answer your question. The phone i bought was from a guy who sold it to me out of eBay with a none working screen, he had the imei in the pics so i ran an imei blacklist check and it was clean. I asked him why he didn't fix it and said it was out of warranty so he just left it dead. I guess it was paid for but in his account so it was free for anyone to use but letting my girl do the unlock request worked so if you have a phone that's not blacklisted and you its not associated to an active account I guess it could be done. Try it, it's worth the try.
Similar question
Very first post, not sure if I should have started a new thread. Anyway, I have an ATT S4 I337 with the MF3 baseband. It's rooted, region unlocked, and fully switched to t-mobile service using a method I found on youtube, which worked fairly well except had to modify two things (I can help if you're having trouble). Now I'd like to upgrade firmware (I'm still on 4.2.2). However, I have a lot of uncertainty because of all the changes I've made. If I temporarily unroot, who am I going to get updates from? Do I need TMO or ATT custom ROMs if I want custom (have they solved that bootloader issue yet?). Basically, what's the safest way to update firmware?
Thanks in advance

The above also omits that if you are on Android 4.3.X than the bootloader on your Samsung Galaxy S4 contains a bootloader restriction preventing any downgrade which means you would be unable to flash MDL (ie. M919UVUAMDL) since MDL is Android 4.2.2.
Does anyone know a way around this bootloader restriction thereby allowing a downgrade to 4.2.2?
att i337 to t-mob stock
Hi, Im pretty new to this firmware and different model numbers etc.. but here goes. I bought a samsung s4 on att i337 a few months ago off a friend. I paid an online company for the unlock code and received the code within 24 hours. The phone is now unlocked and I have a T-mob sim in it, i'm now looking to update the firmware to t-mobile 4.4.4. Can i download a t-mob stock rom for i337?? I'm worried that this might break the phone as everything I see for t-mob is SGH-M919. Should this matter now that the phone is unlocked?? Thanks
No, you need to use ATT firmware due to hardware differences (antenna/radio). Also as I recall ATT S4s have a locked bootloader meaning only safestrap compatible ROMs can be used, unless something changed since I had one last summer. Sold it, on Swappa, and bought a TMob version with unlocked boot loader and sim unlocked!

Hi! I am having major issues with my s4 i337 after switching from att to tmobile. The phone was unlocked so I took it upon myself to unlock it. It is unlocked but sometimes or rather most of the time does not pick up the network. When it does have data connection, it is Edge. I flashed the NC1 to root my phone, then reflashed to NJ4 (to unlock) but now nothing works. No wifi, camera fails, no multitasker, no voice assistant. Please help!!!!! I don't know what to do. I should have never unrooted it to unlock. I should have paid the $35 to get an unlock code. Can I fix this?

I am not sure. I flashed NB1 as suggested by another forum member and everything is working once again. Although it went back to 4.4.2.
Now it has this notification : security notice: unauthorized actions have been detected. It wants me to reboot to revert the changes. How do I make this go away and will it go back to its unusable mode if I manually reboot?

i have samsung galaxy s7 edge att unlocked with tmobile sim card and my last 2 ota upgrade are from tmobile G935TUVU4APK1
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.

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?

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?
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

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.
Thanks for the help

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.
Thanks for the help

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

It is customized to install for multiple carriers. It's a user configurable install. You can pick which carrier you are, which apps to install etc.
It is 4.3

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.

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
Regards

Tried all the 4.1.1 fw from sammobile for all carriers here in PH (Globe, Smart, Sun and Open Line)
The menu code doest lead me to the Perso SHA256.
After the Network Lock menu it says Command don't exist or something like that.
Help me what to do please.

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?

I will post here, in case some one needs it
Rogers Note 2 ~ SGH-I317M ~ Android: 4.1.2 ~ ROM: I317MVLBMA3
===============================
I rooted my Note years ago using CFRoot.
To flash ROM, please follow the youtube video:
https://www.youtube.com/watch?v=KVrhNO__9JY
using all the files from thread: 1987541
files you might need: Kies 2 + ODIN3.07 + TWRP + ROM zip files
///////////////////////////////////////
Tricky thing: the latest TWRP from Google Play won't work on my phone,
so I used ODIN 3.07 to install open recovery TWRP , also used an old version of TWRP 2.7.1.0 ,
download this file - > twrp-2.7.1.0-t0ltecan.img.tar 7.5M
from link:
https://dl.twrp.me/t0ltecan/
After successfully installed TWRP, things will be easier, follow the video using Rogers Modem/Radios zip files
to flash ROM downgrade to: I317MVLALJ2
///////////////////////
You also need to install Kies from Samsung to make ODIN work, which is mentioned in the original thread.
If you use a PC, make sure you use USB com port on the back, not the front ones.
Would it not be easier just to flash stock 4.1.1 from sammobile.com using Odin if the phone is running stock 4.1.2? After unlocking, odin can be used to flash to the latest 4.4.2 or, since the phone is on stock 4.1.1, ota updates would work too but takes a lot longer to get to the latest rom.
I had a i317m on Koodo with stock 4.4.2. I recall flashing stock 4.1.1 which tripped Knox but allowed me to unlock the phone for free. This was about a year ago.
4.1.1 MODEM
Old thread I know but I am not having any luck finding the 4.1.1 modem (Rogers?) for the note 2 SGH-I317M .Updato doesnt have it ,nor sammobile, anything else I came across was very slow downloading and never finishes or were links that lead to unrelated sites. I want to unlock it for free if at all possible but finding this modem is proving to be impossible.If anyone knows where I can download or anyone can provide it that would be great.
Doesn't matter whether the modem comes from the stock Rogers, Bell or Telus ROM on sammobile.com. You need the LJ2: https://www.sammobile.com/firmwares/galaxy-note-/SGH-I317M/BMC/download/I317MVLALJ2/8189/
Now I see why I couldnt find it on sammobile.Only for premium users.I guess forking over 10 bucks to get it unlocked would be a bit cheaper.I suspected any 4.1.1 modem would do but thanks for comfirming that.All this unlocking crap is supposed to come to an end by years end anyhow in Canada.Locking phones will no longer be legal after that here and supposedly any that are locked are supposed to be unlocked for free. Cant wait to see what the carriers will try to pull.
There is no need to pay to download. It's slow, but free. I have a free account and I am able to download.
I feel dumb for asking but how do I download the file. Ive got the free subscription but it still says that its only available for premium?
Are you trying to downgrade an sgh-i317m from Rogers, Telus, or Bell?
LJ2 modem is here: https://forum.xda-developers.com/showpost.php?p=67958065&postcount=8
There is no free download for the LJ2 ROM.
No I was trying to downgrade from AT&T 4.4.2 to unlock my SIM but soft bricked it.
Ohhhh man Im so freekin happy. I finaly got my hands on the 4.4.2 file and got it back to its original state.
I still dont have sim access. Any ideas on how to do that via a root maybe?
What do you mean by sim access? Do you mean the phone doesn't recognise any sim card when inserted?
Companies in the US lock their phones to use only their SIMs. When I boot the phone, there is a prompt to give a code to use my local SIM here.
Oh, you mean the phone is asking for the network unlock code to use a non-usa sim? If yes, you will have to either request and unlock code from the original carrier or buy an unlock code.
This thread is about the sgh-i317m which can be unlocked using software. If the phone is an sgh-i317 and it is not running 4.1.1, you'll have to unlock using a code.
