Hello,
I received a Galaxy SII I9100G as a present last april in Morocco (I'm in France right now). They told me it was an "unlocked" phone (not bought from any operator).
The phone worked wonders with my SIM card (SFR, a french operator) from april until 2 days ago. It seems like it locked itself all of a sudden and asks me a code to unblock the network. That same SIM card worked well the same morning.
Anyone to explain what happened? I'm confused since I don't understand how it can lock itself without having to change the SIM card/flash/anything...
I called SFR and Samsung France to have the code, each one tells me to call the other.
I rooted my phone and used Galaxy S Unlock, it tells me that the phone is unlocked but after the reboot nothing happens. Tried also Galaxy S2 SIM Unlock, but it doesn't find the code.
I'm quite desperate right now since I'm waiting for some important calls this week and I tried everything, every tutorial but nothing seems to work.
I really don't know what to do to unblock it, I asked for help on many forums, spent yesterday looking for solutions but still nothing.
Please tell me there's a solution to this problem?
Thanks in advance for any help~
Samsung Galaxy SII I9100G
Version: 4.0.3 - I9100GXXLPN
PS: Actually, it does seem to work with a Meditel (moroccan operator) SIM card... Which I don't understand since it was supposed to be unlocked, hence why it worked with my SFT SIM card since april...
Hey i think some persons before you has coneckt it with a Samsung account and locked it now over the samsung dive webside. You can try to flash a new Firmeware to fix it
First, thanks for trying to help me.
I already flashed it with a new firmware (2.3.6 >> 4.0.3, always using official samsung), but still didn't work.
Unless should I go back to a previous firmware?
Any other idea please?

Hello,
I'm hoping someone might know the answer as this is the first i've encountered such an issue.
Bought Galaxy S2 from Canada BELL carrier. got the phone unlocked previously. been flashing different ROM and update and is using XWLPM 4.0.4 ICS.
everything was working fine till about yesterday where a "Network Lock Control Key" popped up preventing me from accessing my SIM card. I do not believe my SIM is locked as i tested the SIM to another phone and it works fine without any security password.
somehow my phone is not locked again and i tried all the different unlocked method in the Playstore and nothing worked. it almost as seems the phone re-locked itself somehow.
my question is, is there a way to find out what network the phone is locked to so if i decide to purchase a unlock code, i know that it will work properly?
Appreciate any feedback or suggestions, as i need my phone desperate.!!! :crying:
Version 4.0.4
using Stock XWLPM Kernel (rooted)
Build XWLPM
Baseband using LD3 baseband = UGLD3 <-- Bell Carrier Modem Baseband.
Thanks
Why create another thread ? You've got a related open thread a couple of posts down you could have continued to use (changed the OP & title).
my bad ,total noob move.. i felt that it was a different question so i created another post. i can delete but not sure how!! any direction would be appreciated.
Use older thread. Locked
Hi guys. I got my Samsung Galaxy SII on a T-Mobile contract when it first came out. Unfortunately I got into a bit of a dispute with them and left, and am therefore unable to get my unlock code.
So I rooted my phone and unlocked it and the phone worked fine for a few months. Then all of a sudden I lost my signal EVERYWHERE.
So I tried messing around installing a few roms trying to get my phone's signal back. And may have possibly corrupted my EFS also.
I know (using various guides) how to get my EFS and everything back. However I have no idea which rom to choose.
My phone came from T-Mobile, but I am now on a Three contract. So which carrier do I select when getting the stock rom?
Also CSC? Modem? There are several variants of the stock rom it seems and I have no idea which one to pick!
Sorry if I have missed something, this is my first post. I scoured the website for a good 20mins and couldn't find anything that would help with my particular problem.
Info:
Current Network: 3
Country: UK
Phone: Galaxy S2 I9100
Thanks in advance.

Hi guys, just thought I'd update.
Luckily I remembered one of my family has the exact same phone that was on the same contract. So I typed in *#1234# and boom, I had the correct PDA, PHONE and CSC.
Thanks for the links also. Really helped
hello xda !
I'm a C developper who just received his brand new Galaxy S3 i9305 4.1.2, my first android device !
And i love android. But i just realized it's simlocked and my provider bills 170€ (200$) to get an unlock code !
As i don't have that money and i don't wanna spend it unlocking my phone, i decided to downgrade my i9305 to 4.1.1, and to use the desimlock trick. I did it, using my provider ROM (i'm pretty sure it's the right one). My phone seems to be unlocked, but when i tried to do a test call, i got a weird message:
"Phone not registered on network"
WTF ?
I had a hope when i found ARIZA patch, but it failed, it was made for i9300.
I googled it again for a few days, and i found out that it probably is its modem firmware.
I'm not even sure of it and I hesitate flashing it back to 4.1.2.
Any idea of what causes the issue and how to solve it ?
I'm currently using XXALK2 and i'm from France using the Bouygues network, if it helps
Thanks for your help and time, this is my first post here.
I have seen a number of questions that are simular to this, but I have not been abe to find one that is like mine, therefore I am posting this.
I have a Galaxy S3 International version that was bought from Digicel Jamaica. It is completely paid for, I called Digicel to ask the for a unlock code. they informed me that they do not do that and I would have to go and get it professionally unlocked. the reason I want it unlocked is that I not longer live in Jamaica, but now live in the US and would like to use the phone for the next couple of months until I can get a phone on contract.
I have tried everything I have seen on this site, including getting a unlock key. nothing works.
I upgraded the phone 4.3 sometime ago and have also rooted it in the pass.
Whenever I try the *#197328640# , after [6] Network Lock I get no menu options see .
PLEASE HELP ME :crying: :crying: :crying: :crying:
I have also tried using RegionLock Away and Galaxsim Unlock, both tell me my phone is unlocked, but I still can't use another sim in the phone.
PS. I am using a T-Mobile Sim from straight talk
You can't region unlock on 4.3 at all, sim lock is possible but only if you buy a valid code -there is no other way and your posts are identical to hundreds of others.

I have a valid code, but the SIM unlock doesn't work with the code. I have tried everything I have seen online, downgraded to 4.1.1, replaced the stock 4.1.2 that came with the phone.... nothing works
Hey guys,
I've been trying to unlock my phone for a few days now. Long story short, I moved from Canada to Japan and now I want to unlock my S3 to use a Japanese SIM.
I bought an unlock code from eBay. I was previous running cyanogenmod but then I was told that rooting will cause issues, so I unrooted my phone after an unsuccessful SIM unlock attempt. (wiped the phone, installed stock TW)
Even after unrooting I still had issues, and was given directions for the Service mode. That did not work either. I have tried many different methods and troubleshooting tips and nothing seems to have worked.
Here are some screenshots of the debug mode, my phone details, and a simple root checker app I installed.

My first thoughts are that since its from ebay it might not be a real unlock code.
I have had a lot of difficulty unlocking my GS3, as well. I actually got the codes from ATT, my carrier. I've tried 4 times, each unsuccessful. It says that after 5 failed attempts, the phone is forever locked to ATT, so I'm afraid to try that last 5th time. I was wondering if you could root, and then unlock more reliably. Is that possible?
Root makes no difference, you probably don't have an i9300 if you are on ATT.
