Ive flashed over 24 gn2 and s3's through old modems and menu. There's a sticky about it.
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.
Isn't that what a sim unlock is? Correct me if I have it wrong.
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.
Yes, but that's for 4.1.2 idk if it will work with 4.4.2 I just don't wanna accidentally ruin my phone. And I think you mean LJ2 not MJ2 and thanks that'd be great if you could keep me posted

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.

Sent from my T889 N2/N3/S5..
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.
