Unlock t889 issue - SOLVED

SOLVED:::::::::: Thanks to Pirobo_Colmbino
I recently was issued an official unlock code for my t889 from tmo. I tried to unlock the device using an ATT sim and got the "network unlock unsuccessful" message. Apparently, I'm a dunce and didn't read AND follow the instructions properly and entered the wrong code more than once. Now I am told that my device is PERMANENTLY LOCKED and cannot be unlocked. Is this correct? Is there a way to fix it? HELLLP

Hi, im not sure if this is gonna help, but the way I unlock mine was with the help of a simple youtube search. Im new her so i cant post a link.
Steps: dial *#197328640#
step 1: umts
step 2: debug screen
step 3: phone control
step 4 network lock
step 5: perso sha256 off ( wait 30 seconds than hit the menu key and hit back)
step 6: nw lock nv data initialliz (wait about 1 minute and exit.
reboot and that should be it.
Try that out and if it does not work "meaning you dont see all of the options" all you have to do is downgrade to an older version of Stock " yes you will have to root again but it gets the job done.
If it helps dont forget to hit thanks.

Thanks for your reply. I tried this before and all the worked until it comes to step 5. When I go back, the item "nw lock nv initialliz" (in your step 6), isn't there to select. Perhaps downgrading is the answer?
The part I don't seem to understand is that TMO says because I entered the wrong code multiple times, I lost the ability to unlock. Does this method overwrite or fix the permanent lock they spoke of?

You, sir are correct. I was able to downgrade via Odin, but I lost some functions (which didn't matter since it was only temporary). I performed the steps you provided and tested with an ATT sim. It worked. Then I updated to current stock ROM and rooted. Tested again with ATT sim and my device is still unlocked. Thanks for your help. I hope anyone else who runs into this issue, can find this post and learn like I did.

What Version were you on when you could not unlock it. And what version did you flash?

I'm not so sure it had much to do with the version, although I am no expert dev. Mind you, this happened in a short period of time.
TIMELINE:
I was on The stock (shipped) rom when I first bought my GN2. I got it new and broke the seal on the box. Upon opening and starting the device, I got an OTA update (don't remember the build but not the LL4 ota). I started doing some reading on XDA, since like most, I like tinkering and tweaking. Not long after that (Mid Jan 2013) I got the OTA from TMO that had "minor fixes and security changes". This is when I read somewhere on XDA that it is not recommended that we accept the OTA update. But it was too late; I had already done it. I came across the unlock instructions posted earlier in this thread but I couldn't get pass all the steps. A few days later I rooted via ROOT66_TMO_UVALL4 rom, which gave me access to SuperUser. [I have this ZIP saved if anyone wants it and wants to show me how share it.] Then I got an official unlock code from TMO.
I followed these instructions that TMO sent me with the unlock code
Thank you for taking the time to contact T-Mobile. Below you will see the Instructions for unlocking your Samsung device.
Please be advised a non T-Mobile SIM card MUST be used to unlock this device.
1. Insert a NON T-Mobile SIM & turn Device on
2. The Device will automatically prompt you to enter code into an empty field.
3. Click/Tap in the empty field above the "Unlock & Dismiss" options (this will display a key pad on the screen).
4. Using the key pad input the Unlock Code provided by T-Mobile.
5. Press the Back button to remove the keyboard from screen.
6. Click/Tap the "Unlock" option; handset should display "Network Unlock Successful".
Please note that if you are unlocking a flip device please use steps 1, 2, 3 and 6.

In my haste, I didn't follow the instruction EXACTLY as written. Somehow I managed to enter the unlock code while using my TMO sim and not the "NON TMO sim". When I did this, I got the message in step 6. I thought I was good from here. I tried an ATT sim a few days later to verify but it asked me again for the sim unlock code but the operation was unsuccessful. I tried entering the donor phone's screen unlock code a few times as well as zeros and 1234 and again failed. I tried again with another donor phone with the same result. TMO sent me a second unlock code which also failed. I did tell them that I had done the OTA update and the rep told me it shouldn't matter. I did not tell them I was rooted stock though. The rep told me that due to entering the wrong code multiple times, the device went into "security lockout" and could not be unlocked. I read into several threads and posts and could not find the answer, Thus my original post. I down graded my Rom to T889UVALJ1, successfully performed the unlock procedure posted above (NOT TMO official), and re-installed the ROOT66 rom. Everything is now working perfectly. I put in the ATT sim and it pops right up as ATT.
The real question now is, does the OTA issued by TMO block the unlock exploit and is that what they refer to when they mention "security features"?
Thank for Solving this issue goes to user Pirobo_Colombino see post 2

I encountered the same problem couple weeks ago. The problem is not caused by the TMO firmware update but rather the fact that you tried to unlock the phone using the hack you found on the internet. Per instruction on the free unlock hack online, you selected "PERSO SHA256 OFF", this step is what prevented the phone from being successfully unlocked with TMo unlock code. In order for the TMO unlock code to work, you have to select "PERSO SHA256 ON", then follow the instruction steps to unlock using TMO code. That is what I did and it worked for me. Hope this helps anyone who will run into this problem in the future. Cheers :good:

Interesting....... This is the first I've heard of this. Not to say this info is not out there; I just never came across it. I do hope that this reaches the poster of those links (there are quite a few) as a cautionary note. Perhaps someone will post a how-to compiled with all these tidbits included.

After the sim unlock, sim card in HK still also can use it?

I cannot say it will work with HK sim since I have NO experience with that card or even overseas. However, I can say that ATT&T sim works every time I put it in the phone. Have you ever used a HK sim in another phone? If you did and it worked, I don't see why it wouldn't work in this one.

Provide link?

Latest OTA is 4.1.2
I'm not sure how you are trying to do your unlock. In order to use the unlock method detailed in post #2, I needed to downgrade my firmware. The method in post 2 WILL NOT work after the OTA update.
If you are using the instructions from your carrier, follow the instructions they emailed you EXACTLY. If you have issues with the carrier instructions, contact them; It's up to them to give you proper tech support on THEIR product.
As I understand, the "hack" method is for mostly intended those who have modded/altered/rooted/other-than-stock devices. Whichever method you use, be aware, YOU RUN THE RISK OF BRICKING YOUR DEVICE. That being said, research your steps BEFORE you end up with a dead device.
I AM NOT a developer nor claim to be an expert at any of these methods. However I have been modding my devices for years by reading and researching XDA. I have had success and failures and so will you. The best advice I can offer is to continue reading the posts CAREFULLY and be patient.
I hope this helps

Yep I did in detail what has been said in post #2. ( By default my device is 4.1.1. )
When it didnt worked, I asked tmobile for the network pin. I also followed their instruction thoroughly, after i entered the pin they gave, it gave the message network unlock successfull. I noticed that there still was no signal so i restarted my device. However it still keep asking me for a network pin. When I asked them about this, they just said that they dont really know why.
I also did a factory reset.
Wonder what could be the issue. Any thoughts?

I would call Tmobile again and talk to someone else. Maybe ask for tier 2 support. Many times, the first person you get is a low level customer support person that only knows what the computer screen shows them unfortunately.

[Problem] No signal/sim card inserted error after unlock!

Hey guys, i have a complicated issue with my newly brought Galaxy Nexus SC-04D, here we go:
1. I got it on 4.0.1, so upgraded to 4.0.4 and rooted and installed ****docomo v3.1.
2. It said phone is locked, selected unlock, phone rebooted twice then FC.
3. Reinstalled and opened it, showed phone is unlocked, congratulations.
4. Put in my sim card, phone shows no sim card inserted.
5. IMEI is the correct one, not generic.
6. When i put my Sim card before unlocking it never asked me to put in a code to unlock it.
7. Tried to restore it to 4.0.4 using Odin still no hope.
8. Tried the theory of unlocking it, still no hope.
9. Sim card slot is functioning because when i search for networks, it finds them.
10. ****docomo still shows phone is unlocked, tried locking and unlocking, still no hope.
I know the issue is not familiar, searched for hours but couldn't find any answer...
Any ideas how to get it to work would be very appreciated
Update: Doubted if the IMEI is blocked, but it's not, if this might help..

Noticed this strange network activity!! http://www.youtube.com/watch?v=DnHsB8ya-H4

What were the terms of you buying it? Used? I.e. why was the seller parting with it? Did you read through both the fdocomo.apk thread and permunlock thread? You're best help would be there. I know I looked at them at one time, and the permunlock thread was referencing an earlier version of fdocomo..

It was used yes, and i looked at Fdocomo & permunlock thread of course but still can't get any signal, not even for once!!

[Q] help with carrier unlocking Note 2

hey guys, this is my first post on xda. Ive owned almost every galaxy phone in the series since the S2 and every time i have any questions, i refer to your site to search for an answer. i have found my solution every single time until now. i have tried searching left and right and feel like i have been so close to solving my problem then i find a new problem. heres my situation.
i have a note 2 from US cellular in the US which is CDMA. im traveling to Paris (currently in paris now) and i bought a new Note 2 that runs on GSM. now my problem is that the phone is carrier locked to a korean phone company. I posted this in the ATT section because i could not find a section for my phone model and many of my close solutions referred to using ATT firmwares so i felt this was the closest section.
my phone info:
Galaxy note 2
model: SHV-E250S
Android version: 4.1.2
Device status: normal (unrooted) (i have my US cellular note 2 rooted through one button method and can probably do that to this phone as well if needed, so if you have a solution that contains root access please know i can still go that route!)
so to carrier unlock this phone i read about this easy method:
Step 1: On your Galaxy Note II, launch the phone app and press these keys:
*#197328640#
Step 2: From the Main Menu, navigate to [1] UMTS > [1]Debug Screen > [8] Phone Control > [6] Network Lock > Options.
Step 3: In the Options screen, choose [3] Perso SHA256 OFF. Wait for 30 seconds after making this selection.
Step 4: Go back one step by pressing the menu key, and then back once. You should now again be in [6] Network Lock
Step 5: Here, now choose [4]NW Lock NV Data INITIALLIZ. Wait for one minute after making the choice.
Step 6: After a minute has passed, reboot your Galaxy Note II.
but my problem is that when i enter that first code i get this message: "connection problem or invalid MMI code."
so i searched how to resolve that. i found some threads saying that i need to downgrade my firmware to 4.1.1 because 4.1.2 blocks this on some phones. so i looked into downgrading my firmware. Went to samsung-updates and entered my device model and they only had 4.1.2 firmwares. i didnt try an ATT firmware because im not confident it will work so if i can get assurance that it will ill try that route.
from there i also googled my model and firmware 4.1.1 and found nothing.
somewhere in all this i also was told to change my csc as well. I tried doing that with the code provided online and received the same error message. i would like to change the csc so it runs on UK csc as well.
sorry if anything is confusing, im not a huge tech guy when it comes to phones, but i try. I dont know how to flash roms or anything, only reason i ever rooted a phone was to use free tethering.
in conclusion, i just simply want to carrier unlock this korean note 2.
any help is appreciated as i would like to get a phone plan here in france asap but i want to make sure this phone is going to work. I dont even know how to check if its carrier unlocked after i do succeed in this. i have access to a tmobile sim card if needed to check.
thanks in advance and thanks to everyone who has helped others on this site. i have used your expertise many times in the last few years and now finally i can say thanks for the great information!

[Q] AT&T provided SIM unlock code not working - KNOX issue?

I am selling my SGH-i317, but am unable to SIM unlock the phone with the unlock code that AT&T provided for the IMEI.
When pop in a T-Mobile SIM, the phone asks me for an unlock code. But it refuses to accept the code with message: "Network unlock request unsuccessful".
What could be causing this?
Here's a history of my phone:
1. I have used it with a custom ROM, so the KNOX counter is tripped.
2. I was on a rooted UCUBMK6 ROM with TWRP recovery.
3. I used Triangle Away and unrooted.
4. I then used Odin to flash back to UCALJ2 with Stock Recovery (unrooted), using this tar file: KIES_HOME_I317UCALJ2_I317ATTALJ2_215287_REV04_user_low_ship.tar.md5
5. This gave me stock recovery and stock ROM. KNOX still tripped, custom ROM counter=1
6. I then used Odin to flash the UCUCNE5-Stock-No recovery. I assumed that the stock recovery from the UCALJ2 ROM would work as a "match" (?).
7. Device now reports baseband version I317UCUCNE5, build number KOT49H.I317UCUCNE5. Kernel 3.0.31-1728680. KNOX still tripped, Custom ROM counter=1.
But the unlock is a no-go. What gives??

Have you tried the before method?

No..thanks for the tip. My menu doesn't show that option, probably removed in later ROM versions. But I found this YouTube video that suggests flashing back to an older modem, then following that method, then flashing back. Worth a try...will give that a go.

This helped me unlock my device....
amfractal said:
It was probably mine. I had the same issue and I got my code from cellunlocker.net.
I was on SlimRom and it was not working. I finally went back to the official rom for one final try and it worked.
This is what I did. I'm not sure if just trying the unlock code would've worked but I did follow these steps (it's a bit weird since you don't actually change anything, maybe it forces the phone to refresh something.)
Just make sure you are on official ROM or it won't work (I tried only the code with the SlimROM and it did not work).
After unlocking I went back to SlimRom and then CM and it was always unlocked.
1. Make sure that the phone PROMPTS for the code with a NON accepted sim card and that your IMEI is correct by dialing *#06#
a. Go to the Dial pad and dial *#197328640#
b. Please click on number [1] UMTS > [1] Debugging screen > [8] Phone Control > [6] NETWORK LOCK
c. You will see 3 options
d. Please click on number [1] Perso Sha256 INFO, the screen will change slightly
e. Please hit the MENU button then when the menu pops up please carefully hit BACK to return to the previous screen
f. Next Please click on number [2] Perso Sha256 ON, the screen will change again to a one line message
g. Restart the phone on the screen by holding the power button and click RESTART
h. When the phone prompts for the unlock code simply enter the unlock code provided to you
i. Your phone is now permanently unlocked!

This method worked for me.
FYI- my situation (maybe it'll help others): I bought a T-Mobile prepaid SIM card for my spare GS3 just to see if it would work. I contacted AT&T and they provided me a SIM unlock code (took about 2 days). However, it did not work! 5 days later, and they still haven't figured it out! I decided to take matters into my own hands. After many many hours of research and trying all sorts of methods I believe whats happening its that people are trying the dial pad method and setting their Perso Sha256 to "OFF". If you've done that then unlock codes will not register correctly... So get and unlock code, then set it back to ON following the steps above. Hopefully that helps others..

[4] NW Lock NV Data INITIALLIZ
owl74 said:
PDF file now attached...
Please read the whole thread if you can or at least the whole OP down to the bottom before asking questions as your question might have already been answered... Thank you...
############################################
Hi guys, you can unlock you N7105 via the Samsung hidden menu. [Also works with N7100 and some Galaxy S3 (SIII) variants - NOT ALL]
#############################################
I can confirm the unlock survives ROM flashing
#############################################
Before doing the instructions below, please double check your phone that it is actually LOCKED by inserting a sim card from a different carrier/provider...you may or may not leave that sim card on the phone while unlocking
Note: your phone must be running at least Jelly Bean 4.1.1 (if 4.1.1 does not work, try 4.1.0) otherwise some of the menu choices are not present
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!!! There is no confirmation on the phone that the unlock was successfull.... just reboot your phone....
To test, just insert a sim card from a different carrier/provider. If the new sim card works then your phone is now unlocked.
I have done this to my other Note 2 N7105 originally locked to Orange.....
========================================
Do this procedure AT YOUR OWN RISK
========================================
To those who were able to unlock their phone with the method above, can you please post in the thread and let us know which phone model (N7100 or N7105) you have, Country and Network/Carrier your phone was locked to...... and if I have saved you some cash, please click the Thanks button or the Donate button on the left just below my name to buy me a can/bottle of Heinekken, Quilmes, Budweiser, Fosters, Tiger, Stella Artois, or San Miguel :cyclops: ...
========================================
NOTICE:
To those having "Conditional Call Forwarding" pop up message or similar pop ups appear everytime you make a call (but they disappear within a few seconds), this is normal with an old sim card, or when using a ported number. There is no restriction to calls or internet or whatever. This is confirmed by my provider when I walked in and asked them about it. They even showed me one of their sample Note 2's and S3's having the same message.
========================================
I have mentioned in my old thread that there was a pop up message that says "Conditional call forwarding active" everytime I make a phone call using another SIm card that the phone was not able to use before unlocking.
I can confirm that this was due to my Sim card. It is a very old O2 sim card that I have used for years. I have tried that Sim card on another factory unlocked phone (Galaxy i8160 bought from P4u) and it had the same message.

i tried unlocking via the thread http://forum.xda-developers.com/showthread.php?t=2014982http:// but dialing the number *#197328640# does not show any menu my android version was 4.0.1 but after software update it became 4.1.2

For unlock i371 we have 2 ways:
1)If your phone have 4.1.2 or less you jast need to try unlock codes:
*#197328640#
Select [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 and then select Back.
This will take you to [6] Network Lock options
Choose [4] NW Lock NV Data INITIALLIZ
Wait for a minute then reboot your phone.
Insert a SIM Card from a non-AT&T carrier
IF it not help to you, you need downgroad FW.
2) if you have 4.2.2 or more(4.3, 4.4.2.)
You need to wach this video and unlock your device! youtube.com/watch?v=KVrhNO__9JY
You need downgroad MODEM FW(NOT ANDROID VERSION!!!) and use *#197328640# from 1 step.

GT-N7100 carrier unlock not working
Ok, so I tried to post this in the appropriate GT-N7100 carrier unlock thread, but I'm too n00b 'round these parts so here I am making this thread.
So this phone was initially locked to Telus, but I'm trying to unlock it so it can work with Rogers. I already possess a Rogers MicroSIM card that lives in my S3 so I have a valid card to test. It has Cyanogenmod 10.2 installed on it, by me, which was done about a year ago. I also think, at the time, that I attempted to carrier unlock it, but I can't remember if it was a success or not. But right now, I have been tasked - again - to carrier unlock this device because it apparently doesn't work.
I now believe that to be the case, as I have my S3's SIM in it right now and the phone displays a message saying it can't connect to the network (Rogers). Yes, I have manually scanned for networks, and they do appear, but I can't connect to them. I also tried dialing *#197328640# to reveal the hidden carrier menu, but when I press the call button it says there's no mobile network...
That makes no sense, this is supposed to be an ingrained menu, why would you need a network?!
The phone's details are as follows:

Could this be solved by reverting to a stock ROM? Or can I keep Cyanogenmod? Because I'd really prefer to...
If any further details are required, I'll do what I can to answer. Please, help me get this phone back to a service ready state!

@FlashExplorer you have to be on a stock ROM to access the hidden menu to unlock

Click to expand...
Click to collapse
I see! I will revert to the stock ROM and then install Cyanogenmod afterward.
Thank you very much! :good:

Not working for N7100
After tried with 10 different firmwares including the very first one rolled out (I tried it with a full Stock including modem, boot, hidden, recovery etc)... I can conclude that this method does not work for N7100 (exynos based).
After reading the posts, I saw that no one with a N7100 reported success, everyone stuck up with the patched menu. So, I suggest to remove the N7100 in the first post since it does not work for it..

Sorry for asking this but with lots of people making topics about same topic its geting confusing.
I'm looking to unlock 2 x Canadian Note II I317M's
# 1.) Is running NH2 4.4.2 Firmware
# 2.) Is running MK5 4.3 Firmware
So can I just downgrade the modems to MODEM_I317MVLALJ2 rather than downgrading whole Rom If so how can I do this?
Only asking because some are saying you can and some are saying you can't. Sorry again for asking this. I just don't want to brick these phones. One is for my pregnant wife and one is for me as our 2.5yr old broke both of ours and got these ones second hand but they are locked. Just don't want this to be wasted money.
Thank you all xda'ers in advance

Unlocking Nokia Lumia 520
Hi, will the steps you posted to unlock the Samsung phones work on the Nokia Lumia 520?
I bought this unlocked phone in the UK and it works with sim from any UK providers, however when I take it to Argentina it won't recognise the SIM cards from local providers. Somebody mentioned that it may have something to do with phone bands, that it may be unlocked for use in Europe but not outside of the EU...I've never heard of phones bands so not sure about this. I'd be grateful for any tips you could give me.
Thanks!!
