Hello guys,
I have this problem, i got a note 2 from a carrier in argentina called "personal" wanted to sim unlock it so i followed the easy way
of the hidden menu " network lock " and that tutorial.. ( cant post links yet )
But it did not work cause i had 4.1.2 , so i got 4.1.1 also did not work, so i read you need VALK8 baseband to sim unlock it.
Got the VALK8 zip file, rooted note 2, installed custom recovery, installed the .zip file . and got a UNKNOWN BASEBAND djaskdsjakdasjd!
How can i fix this? need the VALK8 to get to the menu sim unlock it and then flash 4.1.2 again
Thanks a lot i hope you understand this !

Ok i installed a 4.1.1 and now i have the baseband restored to DXALJ1 i think it is asian dunno.
How can i SIM unlock this and then put 4.1.2 on it?
thanks i will really appreciate it!
First of all, what model you have?
Im assume you have carrier lock model,
1)Root your phone.
2)go google play download either *galaxsim unlock* or galaxy_s unlock.
Follow the instruction as given, then you will be fine.
If I were you I will download the old time 4.1.2 stock rom such as mb2. Since you might not aware of the new samsung stability update will messing up your imei and modem.

Is it possible to Sim unlock 4.4.2? Maybe by flashing a 4.1.1 modem?

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.

What bootloader were u on?
Sent from the TermiNOTEr 2! ?
when updating past 4.3 you aquire the updated bootloader and can no longer "safely" downgrade to 4.1.1 to unlock this phone. however if you:
1) Root the phone and allow SU to disable knox
2) Install custom recovery (TWRP, CWM, OR OTHER)
3) Boot into recovery and flash the atti317ucalj2modemfixed.zip modem
4) After reboot you can use this method to unlock:
(From this thread http://forum.xda-developers.com/show....php?t=2014982)
Just dial the following keys *#197328640#
Main Menu > [1] UMTS > [1] Debug Screen > [8] Phone Control > [6] Network Lock > Options [3]Perso SHA256 OFF > (after choosing this option, wait about 30 seconds, then go back one step by pressing the Menu button then select Back, now you are in [6] Network Lock then choose [4] NW Lock NV Data INITIALLIZ ..... wait for a minute then reboot your phone... enjoy your unlocked phone!!!
5) Reboot recovery and flash the newest modem I317_ucucne5_modem.zip
6) Reboot again and enjoy your fully unlocked 4.4 note 2 att with out losing your data or bricking your phone
************* non at&t notes try using earlier versions of your own stock modems then updating after unlocking ************ @umaza has infomed me this method Seems to have worked for 4.4.2 i317m Koodo, just downgrade to the Rogers Modem,

With all due respect to OP and his lack of posts (like I have room to talk, right? ) can anyone else verify this as working before I attempt this? I need to unlock my phone and would rather do this than flash 4.1.1 (and trip Knox) and then reflash to a 4.4.2 ROM.

i hope others will try this and post their progress, but just as a personal reference in my repair/modification store i have now successfully unlocked 16 note 2's that i have bought and customer's phones. hope this information helps.
The information helped a lot when the other guy figured it out and posted it a year ago.
ok that didnt work for me i get an error, nothing happens til I hit send on the dialpad, then I get this connection problem or invalid MMI code

the other posted method works for previous software, the method has to be tweaked to work on 4.1.2 and above. im guessing people arn't reading that part of the post just assuming this is the same unlock method that use to work with out flashing the modem. they removed the #4 prompt in network lock on the newer modems so you cant manually unlock them.

I'm running an AT&T Note 2 (SGH-I317) running Ditto Rom 3 v2, baseband I317ucucne5
Hi I bought an att note 2 with 4.4.2 will this method work.
baseband
i317ucucnj1
kernel
3.0.31-1728680
build
kot49h.i317ucucnj1
works
I just tried this on my note 2 with 4.4.2 and it worked perfectly. Thank you.
Would this work on an Canadian sgh-i317m?
I am going to try this on my i317m (Koodo) Dn3 Rom, will post results soon
Edit:
Didn't work, when I put numbers on dialpad, it doesn't go right away, I then press the call button and it says "Mobile network not available"
Should I try going back to Stock Rom, then trying it? Will it stay Unlocked if I restore a previous EFS?
Edit2:
Went back to stock 4.4.2 Koodo, and did the following, but when I put numbers on dialpad, it goes through but everything is blank, like there is no menu to choose from
Did you downgrade the modem/baseband first before using the dial pad? This menu is only accessible in the older one. Also I'm not sure of the compatibility of the modem with a phone other than the I317 att. Other variants probably have a different modem and you'll have to find an older version of yours to flash then flash back to current.

Yes, I downgraded to the one you have provided, and surprisingly it was not accessible, but on my stock modem, the menu is accessible but doesn't work.
That was also my thought, time to modem hunt!

Dumb question:
Do I need a SIM installed before attempting this?
Edit: The answer is no
SGH-T999 got flashed to CM, everything works except I can't access my network. IMEI and IMEI SV and Broadbase are all showing as "unknown". Dialing the weird IMEI code crashes the dialer. Restored a 4.3 ROM, still couldn't get a signal. Tried installing the newest modem, no luck. What do I do? Is my phone completely ****ed and should I be looking for a new one?
Update: Tried reflashing CM again, now it says "No SIM card". I'm so lost.

Hey I'm not sure what you mean by bootloader but I downloaded the UVUENC2 modem for T999 from this guy http://forum.xda-developers.com/showthread.php?t=1880987 and installed it. No luck.
The phone is a T999 or T999L?
NC2 is the latest for the T999. Does the bootloader match the modem?
Actually now that I checked the back of the phone it looks like it's actually T999L.
If it's a T999L, the latest firmware for the phone came out in October, 2014.

The bootloader is not locked on the AT&T S3 (I747). You can use Odin to flash a custom recovery and flash any ROMs for d2att/d2lte you want. No unlocking required. It is a pretty modder friendly phone.
The thing you cannot do on the newer bootloaders is downgrade the bootloader. Attempts to downgrade anything beyond the 4.3 bootloader will result in a hard brick. This also prevents you from using the free sim unlocking method because it involves a firmware downgrade to 4.1. If you need to sim unlock the phone to use it on a different network you'll have to get a code from AT&T (they should provide one since a phone this old just about has to be off contract) or purchase one from a third party.

I concur with @jason2678
I have an AT&T SGS3 (d2att/i747) that is on the NE4 bootloader and modem (4.4.2) and am running CM11 atm. As a matter of fact, none of the CM or AOSP roms since late in 4.4.2 development will run unless you are on one of the 4.4.2 bootloaders (NE4, NJ1, NJ2)
What you stated, quoted above, is true for the Verizon SGS3 (d2vzw/i535).

It appears that you have an NE4/Android4.4.2/KitKat rom installed over 4.3 bootloader and modem. I have seen several custom TouchWiz roms that run fine with this setup as long as one of a couple of custom kernels were installed. CM and AOSP roms will also run in this condition. BUT, from what I have read you will not be able to use the unlock codes. My reading indicates that you must be on complete stock ROM for the code to work, including stock recovery instead of CWM. ALSO, what I have read says that you only gt five attempts before the code becomes invalid.
I don't know why your phone is not asking for the unlock code, unless it has already been carrier unlocked. Even thouhg it is not asking for the code, does it function as it should?
Frequently the service modes do not work on custom roms, even TW based ones, because they are not using the stock dialers. I have also seen it reported that some were disabled with the 4.3 update and others in more recent updates.
Proceed carefully.
You may be able to enter the unlock code if the phone is running a stock dialler with a matching bootloader and modem combination.

Thanks for respond
I had this phone since 3 years ago (new from ATT) and rooted stock rom with CWM 6.0.4.7 recovery touch . and I remember that I could unlocked through SERVICE MODE when I was overseas. ( sure I had used this phone with Other carrier) about 1 year ago I put this phone in my drawer I did factory reset and installed Stock firmware and update OTA to 4.3.
Last week I want to use this phone with Tmobile SIM but got Phone Not Allowed MM#6 message . The rom was still 4.3, Contact AT&T and got Unlock code.
but this phone didn't ask for unlock code entry option and still 4.3 , tried the whole weekend with service mode and upgrade to 4.4.2 via CWM recovery.
and still no luck
With your suggestion , it means that I don't have choice to downgrade back to 4.3 rom same with my bootloader and baseband? I heard we can't downgrade if we already in 4.4.2 , is that true?
But I still use stock recovery from CWM.
Before I proceed with replacing with stock recovery, is the stock recovery have to be 4.3 stock recovery or any version for S3? do I need to use odin to change to stock recovery?
if you have good link please help?
Thanks again

You may be able to enter the unlock code if the phone is running a stock dialler with a matching bootloader and modem combination.

Stock dialer means the entire Rom must be replaced to match my bootloader and modem combination or just replace the dialer in my case and still use 4.4.2?
Appreciated if you can help, thanks
Stock dialler requires a stock Samsung kernel.
From what I am seeing, you are on the 4.3 bootloader and modem. As I said before, there are custom TouchWiz 4.4.2 Roms that will run on the 4.3 bootloader and modem. Changing to a 4.3 rom, stock or otherwise, therefore would not be downgrading your bootloader and modem.
What rom are you on?
Some of the custom TouchWiz roms use dialers from the S5, therefore not stock for the S3.
Some of the custom TouchWiz Roms use the stock kernel, some use a custom kernel.
Did you flash a custom kernel?
What is your kernel version? (check under Settings > About Phone)
With the answers to the questions I asked, audit13 and I may be able to give more definite guidance. It could be as simple as flashing the stock kernel and a stock dialer. But, I can't tell at the moment.

Are you saying you unlocked it before? If so it should still be unlocked. Flashing/wiping won't affect that, so it's pretty much a permanent thing. If so, maybe the Sim card you're using is an older one? they don't always work on tmobiles networks.

Thank you for your responses , Sorry I couldn't response any sooner as I worked in mountain/forest area that browsing the web is luxury
(yes I remember for sure I have used this cell phone overseas couple times and the way I unlocked through service mode. Way before AT&T OTA update since new)
I have weird situation that make me wondering if I had unlocked my S3 since message
"PHONE NOT ALLOWED MM#6" comes up if I use any other carrier beside AT&T
Per http://forum.xda-developers.com/showthread.php?t=2789917
thanks to OP
I just managed to change my bootloader to I747UCUFNE4 and also my baseband version to I747UCUFNE4
I still keep my CWM 6.0.4.7 recovery touch
I have Flashed with countless other rom such below:
I747UCUFNE4_Stock_Rooted_Odex.zip
I747UCUFNE4_Stock_Rooted_Deodex_3-31-15.zip
I747UCUFNE4_Stock_Rooted_3-31-15.zip
and even custom rom without any success
This was happened with my S3 after flash.
if I flashed with inserted active SIM Card (T Mobile or foreign SIM Card)
I will see PHONE NOT ALLOWED MM#6 after reboot
if I flashed without any SIM Card inserted after reboot :
- inserted foreign sim card and reboot again
I will have AT&T as roaming provider and for about few seconds received text message about fee from SIM issuer roaming to AT&T so means My S3 is unlocked...
(no... not so much!!!) in few minute I will have "PHONE NOT ALLOWED MM#6" and phone is useless as emergency only.
- inserted T-Mobile Sim Card and reboot again it shows "PHONE NOT ALLOWED MM#6" immediately
My Kernel Version :
3.4.0-1514807

Thank you if you can help.
So you are not getting asked enter a network unlock code when running a stock rom with a foreign sim?
Does your provider use aws frequencies? The i747 does not natively support T-Mobile aws frequencies.

No, It doesn't ask at all. just pop up "Phone not allowed MM#6."
my foreign SIM is ok.
I tested on Galaxy Note 4 T-Mo (unlocked) it grabbed ATT roaming,
tested on Iphone 4S (ATT-unlocked) it grabbed Tmobile roaming:laugh:
I just flashed stock recovery and still no go..
do I need to unroot?
Can I flash stock root rom with stock recovery
Thanks
What rom was on the phone when you inserted a foreign sim?
If you are running a Samsung rom, try this:
Www.unlockriver.com/Samsung-unlocking
I am using I747UCUFNE4_Stock_Rooted_3-31-15.zip
I just replaced CWM recovery with UCUFNE4 stock recovery
I did unroot with SuperSU and also
do factory setting through setting menu
basically my phone just as new factory setting but with UCUFNE4
the funny thing is :System Status: Custom is this related I have rooted this device before?
When I turn on bootloader mode (Odin Mode)
product name : SGH-I747
Current Binary: Samsung Official
System Status: Custom
Qualcomm secure boot : enable
warranty bit: 1
bootloader ap Swrev: 3
as I have stated at my 1st post that I had official unlock code from AT&T and got email from them the unlock PIN
but there is no option asking to key in the PIN with other carrier sim inserted .
I have checked also with Swappa esn check
and result is
Blacklisted => Not Indicated
This device does not appear to be globally blacklisted.
spent countless hours just to beat solving this device and read the threads and no result. And still "PHONE NOT ALLOWED MM#6"
