Hi community, as I stated on the title, im having a little problem here with the current 4.3 upgrade on my Note II.
Thing is I upgraded via Odin to 4.3 version; still, my provider service doesnt have the 4,3 upgrade, its only been released to free from fabric phones in my country.(downloaded from sammobile). Shouldnt have been an issue, but after i made the upgrade, my network got blocked. I ve read a lot of threads concerning this issue but still couldnt find a solution.
A link to possible answers would be super appreciated, or something.
Thnx in advance ! Hope i find a way to solve, have EFS saved in pc.
btw IMEI isnt wrong, its not a generic one.
It says : Service State : out of service
My phone number: Unknown
Rest of data seems fine...
Another thing is I sim unlocked the phone when it was at 4.1 to be able to use Movistar on it (via Galaxy S unlock worked) After upgrade network got locked again and asks for simlock code, tried with unlocker again and this time had no luck.. I dont know if the problem here its only that the sim unlock got locked again after the upgrade or what..EDIT: I cant use any of my chips, all of them throw "not registered..etcetc" msg... However this didnt happen when it was at 4.1
EDIT ONCE MORE: I ve been reading around, and seems there is no current way to unlock sim for all companies for note 2 at 4.3 ? Is this correct ? This is frustrating ._.
sry about the double post, anyone can confirm this last thing to me ? Is it correct there is no current way to unlock sim for all companies at 4.3 stage?

I have the same problem, and i found 2 ways to do it :
-either buy an unlock code ( about 25$)
-or downgrade ( if it's possible to 4.1.1, and use the classical way ( with samsung Code)
i hope that someone will suggest another way to do it
@julesarg, have you tried the patched kernel and modem from this thread?

Hello guys, i want know some informations about this device.
With AT&T you can upgrade firmware to ICS official ROM, But is locked by carrier : AT&T (so you cant use any simcard of others countries).
If i Flash the devise with CM10.1, I unlock the phone too (so i can use it with all simcard of all countries) ?
I read a lot forums and sites, and i heard people the carrier AT&T RE-lock the device after 3 - 4 Months!! How they can do it ? xD (i think is for some upgrade firmware?!?!?)
Sorry for my NOOB question .
Thanks Regards !

If you take a look around here, you'll notice that the unlocking has to do with the efs folder and the nv_data.bak file. A search would tell you how to unlock your Cappy Glide. Note that you should use the method that does keep your IMEI intact, and DO make backups of your phone and especially the efs folder before doing anything with it.

Yes, either one works. I'd recommend the second one for you since it'd be easier for beginners to use.
ROM's don't usually mod the efs partition, though some do mess it up iirc
I was given the unlock code and it still says request to unlock network unsuccessful, it's eligible to be unlocked...
All help would be greatly appreciated.
Should I try flashing over back to this stock rom and then see: http://server10.stockroms.net/download/GalaxyNote2/SGH-I317/I317UCALJ2_I317ATTALJ2_ATT.zip
I hate being stuck in a rut like this, already had my account transfered to a T-Mobile microsim. This is driving me nuts...
The person I bought this phone from said they updated but then when I checked it was still at 4.1.2 and said something about update interrupted...
Or which of these should I use: http://www.scottsroms.com/downloads.php?do=cat&id=71
Flashing a Rom won't unlocknyour phone..... Also what do you mean your still on 4.1.2?? That is the latest Rom for the phone. ... Where are you obtaining your unlock code from? The only time att provides it themselves is over the phone. You sure your not getting the wrong code?

Yes I got the code from AT&T over the phone, called them twice and got the same code 1-800-331-0500 they gave me 41907314... According to this: http://galaxynote2root.com/galaxy-note-2-tutorials/how-to-unlock-sim-for-free-on-gsm-galaxy-note-2/ if ya take the newest update, ya can't sim unlock the phone cause it takes out the “NW Lock NV Data Initiallize” (Step #9) according to YouTube user comments...
THIS IS WHY I'm wondering what Stock firmware I need to downgrade back to in order to get that option again and be able to sim unlock my phone.
So I'm wondering if it's I317UCALJ2 or I317UCALK7 that re-enables that option for me. Right now I'm on I317UCAMA4...

Sorry bout the 2 posts, I thought it'd auto-append them to my main post...

No I mean while doing this process? Odin thing.. does it matter which SIM I have to keep in note
This http://galaxynote2root.com/galaxy-note-2-tutorials/how-to-unlock-sim-for-free-on-gsm-galaxy-note-2/ is the tute I believe, gotta remember it's been 2 months since I did this, so I'm not quite 100% certain. LoL
I'll be having to do it all over again too, by the end of this week possibly, since some jerk decided to steal my note 2 I had to go to ebay and win a new one.
I don't think it'd matter during the Odin flash with a AT&T sim card or T-Mobile one in it, I can't remember if I did it with or without a sim card, but to be on the safe side I'd do it without a T-Mobile sim card in it, just for that first successful boot... Then do the 4.1.1 unlock code method, take the back and battery off then pop in the T-Mobile sim card(Or whatever other non-AT&T carrier sim card) and see if it done it correctly...

I bought an AT&T live demo note 2 that was used in an AT&T store. I used this method from youtube, popped in my niece's T-Mobile microsd and dialed 611. T-Mobile's customer service rang and answered showing it worked. You need 4.1.1 to use this method though. I'm going get me a microsim today since my vibrant doesn't use the micro.

The above is not true - if your phone has upgraded firmware, you will NOT see the item "NW LOCK NV RAM...." in your "NETWORK LOCK" "PHONE CONTROL" menu.
So, the ONLY two solutions are:
1) keep bugging ATT to create a case for you and investigate
2) downgrade to 4.1.1 modem (NEED TO READ/UNDERSTAND HOW TO FLASH etc.)
then apply the Samsung service menu "fix" as shown in the above video...*
*Then, you could upgrade to newer ROM... if you wish....:cyclops:
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 !

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.

Hi all,
I would like to start off by saying that i dont care about any warranty or any such issues. I had bought a S4 in US which i brought to India without ever activating on T Mobile network. This means that on contacting T Mobile, they are unable to send me any activation code which could SIM Unlock my device.
So now my only problem is to make my device usable. I see two options:
a) SIM Unlock
b) Complete removal of firmware and install some custom ROM, bootloader and other components to get rid of T mobile network
Problem is that i am a newbie and couldnt find any thread that could help me. MY device is updated to the latest version i.e. i am on 4.4.2 with baseband as M919UVUF9B4 and knox bootloader
Can someone help me out. I have already tried rooting the device and trying some apps which suggested that would help me unlock my device but none of them worked..
Thanks

If you paid T-Mobile the full price for the phone approx US$500-US$600 (not the subsidized price) before you left, they should provide you with the SIM Unlock code. You may need to talk with another customer service agent. However, if you only paid the subsidized price, then you've broken the contract with them, and they won't. You'll have to contact a company that will sell you an unlock code.
As to rooting the phone, have you tried this one: http://forum.xda-developers.com/showthread.php?t=2294005 ?
If this doesn't work, you're doing it wrong.

Flashing a custom rom will not allow it to work on a different network. The phone will still be sim locked.
Like the post above me says, call T Mobile and have them give you the code. If you didn't pay the phone off, they won't give it to you nor should they.
Chainfire's Region Lockaway app will SIM unlock in the process of removing region restrictions. I remember reading something to that effect anyway.
For use chainfire's Region Unlock, you must be root.

Hi
I made a stupid mistake with my G988B, its were not working well, so I decided install a stock rom, but downloaded and installed o last version of software from another country (G988BXXS2ATD5, XEF ) whit Security Level Patch of may 1, 20.
After installed new stock rom, my phone ask for Network Unlock Code.
When realized of my mistake, tried reinstall orignal version of firmware (G988BXXU1ATCT, PGU) but nothing work for me. I have tried to flash with Odin, but always, process stop in "flashing vbmeta.img."
I have read a lot tread trying figure out my problem like: https://forum.xda-developers.com/galaxy-s20/how-to/howto-root-s20-series-upgrade-firmware-t4079353/post82220417#post82220417

Could this process work in my case without damaging my phone?

Thanks por your answer, but I did it.
It doesnt work.
Samkey is the only way to unlock a Samsung phone other than getting the network unlock code from the network or third party. You must know what you are doing. Google the process. If that doesn't work then there is an issue here that needs further investigation. Also ensure your active csc code is the one that was originally on the phone as well as stock rom. Sam key can be used to change csc as well.
Good luck

Thanks mikey_sk,
My problem is that both the csc code and the stock rom are not the original ones. Therefore I am looking for a guide to help me how to get back to the stock rom.
I have read that the problem is, the security patch that I installed as it is newer than the one I am trying to reinstall. I will keep trying.
I understand that so far there is no way to go back from binary 2 to binary 1.
Any help is appreciated.

No more questions.
You can always use the sim slot 2, it is usually not locked.
I suggest you change the csc to a stock one using Sam key. Make sure you enable USB debugging in developer settings otherwise Sam key won't work. After that dowload the most recent stock rom for that device from sammobile and flash in ODIN but DO NOT use HOME_CSC so it can do a full wipe and rebuild the firmware. As an added measure as soon as installed go into recovery and do a full wipe. If network is still locked try unlocking it with samkey

Unfortunately for it, you mentioned only sim1 is blocked and you still can use sim2.
This is not network lock but rather imei blacklist.
The only way to fix this is to pay your telco bills from where you purchased the phone. If it's a used phone, I would get a refund. There is no roms you can use that can fix it as it's blacklisted from the telcos.
There is only 2 reasons it is locked.
1. You didn't pay your installment bills.
2. The phone is reported as stolen.
If you purchased a used phone, get a refund.
