[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 try this link .... http://forum.xda-developers.com/showthread.php?t=1949687

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.
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.

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

[Q] Cannot Update My S3

Hello fellas! It's my first post here, but I've been a member for quite a while now. Anyway my question is how do I update my Samsung galaxy s3. It's an At&t s3 but I use T-Mobile on it. I'm stuck with the 4.1.1 because I can't update it. Whenever I try it says software update interrupted check again in 48 hours. I did search through the forums about this and someone fixed this by using another sim, I tried that but it didn't work.
A couple things to note, I did root my S3 with the cyanogenmod but I went back to stock rom and did the triangle away. I also unlocked my phone using that dial method. Please help me guys. Thanks!
Oh and here's a picture, the continue update is grayed out.

You have 2 options ...
1) Find a valid AT&T SIM and temporarily place that in your phone to get an OTA update via Wi-Fi
2) Install custom recovery (TWRP or CWM) and manually update to 4.3 using the stock restore image posted in the thread below
http://forum.xda-developers.com/showthread.php?t=2658486
This will unroot your phone (if currently rooted), update your system to full stock 4.3, reinstate stock recovery and reset your flash counter.

Thanks Larry. I tried using another sim before and it didn't work. But then again that sim wasn't At&t. Hopefully the first option works. Now I'll have to look for an At&t sim card.

Just to add that OTA update could take anything from 30 minutes to 2 hours depending on the speed of your Wi-Fi connection so if you are 'borrowing' someone's SIM, to have an idea of how long you'll be needing it.

OTA Update Today for AT&T Note 2

Check for OTA Update in your settings.

Is it Lollipop?

I don't think so. I think it is a security update.
I'm rooted on stock rom so i just froze it using Titanium backup. Heard people installed the update and it froze there rooted phone.

I wouldn't. I just posted this in the other thread about the OTA:
a042349 said:
Same thing happened to me. Rooted but otherwise stock GN2. Got the update, rebooted and it got stuck at the boot logo. I tried everything. Flashed CWM, then tried a couple different ROM's. Then went to TWRP recovery, and tried the Team Elektron ROM, that got a little farther, boot logo with sound, but it still hung. Tried a modem update, and even the bootloader - nothing worked.
Luckily I had just bought mine ($300 on Amazon right now) so I just sent it back as defective and ordered a new one. Gonna be real careful of the ATT update and maybe even skip it and go right to a custom ROM.

Best way is to download a custom recovery and flash it in Odin. Then when boot hold on the home and up key to enter recovery. If the phone boot complete withou enter recovery, the recovery would be replaced with the factory recovery. When in recovery flash supersu zip and restart. The recovery will be replaced with the factory recovery, but you had root installed, enter supersu and reboot.

Did it really work?

I don't understand one thing - official 4.4.2 OTA was released over a month ago, correct?
I have two Note 2 SGH-I317s AT&T branded with OEM 4.3 (no rooting or other non-OEM additions).
If I stick working AT&T SIM card and check for updates it says the device is up to date.
Moreover if I'd connect it to Kies it would also say that firmware is up to date!
Same thing on both phones - what am I missing?
I purchased them used - maybe the previous owners rooted them and this prevents them from updating?
One had a Knox at "1" since I for some stupid reason downgraded it to 4.1 via Odin (and then took it to AT&T service center where they flashed 4.3 back), another one has Knox at "0"...

I don't understand one thing - official 4.4.2 OTA was released over a month ago, correct?
I have two Note 2 SGH-I317s AT&T branded with OEM 4.3 (no rooting or other non-OEM additions).
If I stick working AT&T SIM card and check for updates it says the device is up to date.

Is service activated on the AT&T SIM? That might be a factor.
Regardless, there are two 4.4.2 official releases for the I317 - NE5 and NJ1. If OTA won't work for you, check my sig for links to packages that provide another way to get the complete stock firmare on your phone - rooted or unrooted.

Yes the SIM card has normal active service on it.

Other reasons OTA won't work:
1 - Location (if you are not in an area where OTA updates are provided, then...
)
2 - AT&T Update apk disabled on phones (seems unlikely that this would be the case on two phones but a factory reset might clear this as it is set on the data side)
3 - Identity issues (could be any number of things related to IMEI, efs partition scrambling, etc - just spitballing)
As far as suggestions go, I'd say try a factory reset and clear cache from recovery. If that doesn't work, maybe go back to AT&T and see if they can figure it out - the phones are stock and it's their OTA process. If that doesn't work, you can pursue the path I suggested previously - same firmware update, minus the script that pushes stock recovery every time you boot. You will trip the knox flag though...only an issue for warranty repair really. Others here have intentially or unitentionally received the NJ1 OTA with the knox flag tripped on their phones.

I don't think so. I think it is a security update.
I'm rooted on stock rom so i just froze it using Titanium backup. Heard people installed the update and it froze there rooted phone.

Which process did you freeze?

I did a hard reset and finally took 423.13(!!!) Mb upgrade! Be careful what you wish for
Got 4.4.2 I317UCUCNE5

Glad to hear it. Wait a day (or disable network time and the set the time on the phone forward at least a day) and try again - you should get NJ1. (If that's what you want). Approx. 93MB security and minor enhancement update.

Just to follow-up - it took the second update with T-Mobile SIM card even without waiting for 24 hours.
I guess in order to take the updates the phone's IMEI MUST re-register on AT&T network with the valid AT&T SIM card first.
It's now I317UCUCNJ1

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=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.
