I have a samsung S2 (GT-I9100), I was using it in my country (Tunisia) for years, then i went to belgium, and bought a sim from there, and it also was working well. When i went to back to tunisia, I tried to update my android (with the Belgian SIM on) version from 4.0.3 to 4.1.2, but the device got locked! each time it asks me for the network sim pin. How can this happen? the device was not bought from an operator. And my main question is how can i find out which operator locked my phone, so i can ask them for a PIN?
Thank you

Thank you for your reply,
But i have already tried that, along with the "Samsung S unlock" app, i even extracted the hash myself from the data file, but couldnt crack it.
And now im looking for which carrier locked my phone in the first place...

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?

Hi
I'm not sure if this has already been answered on here so please forgive me for asking again if it has,
I bought a samsung galaxy S3 in the UK, and I am going to South Africa next week and wanted to give the phone to my sister, was wondering how to change the csc from UK to the South African network.
I will explain, when I bought the phone, it is a 3 network mobile, I put my vodafone sim card in and it said "sim unlock pin"
I rooted the phone, bought the voodoo unlocking software and it seemed to do the trick, so now when i put my vodafone sim card in, it doesnt ask for a sim unlock pin anymore, and if i go and look in my available networks i see a whole load of networks for example the list looks like this
Vodafone UK(3G)
current network
vodafone UK(2G)
Available Network
T-Mobile Uk(3G)
Forbidden Network
and so on,the list goes on, i only have Orange that also says available network, the rest say forbidden network.
When I type *#726#and my imei number, press the dial button, it doesn't do anything but comes back and says "not registered on network"
Can anyone please help me??
Thanks in advance
Its *#272*Device IMEI# be careful. This wipes your device.

you can't change csc in a single csc rom! it works only in multi csc roms!
i think you have to change rom to have network working properly...
You need to flash a rom from south africa (just look up sammobile.com for the fitting file) in order to choose an south african CSC the way it is mentioned above.
By the way:
You said, you used voodoo sim unlock? After flashing one of the incmoing Jelly Bean Roms the Simlock might be active again!
Voodoo doesn't work on JB Roms.
You might want to simunlock you're phone using this method again: http://forum.xda-developers.com/showthread.php?t=1846451
Good luck
Hello guys,
I've tried to cut it short.
I would try all day unlock my S3 sim lock, but its failed every times. I am new in android customization so I read all things what I found, mostly the best hopes in here. So, it was an sim unlocked Galaxy S3 when I bought it, with android 4.0.4, I would like to upgrade it to 4.1.2 stock rom but it was some custom rom so its wont went automatically, I used Odin to Flash it with the stock 4.1.2 what I found here but it has the sim lock, I was tried more 4 unlocked roms but its stayed sim locked, I try all methods what I found but nothing worked, now the default IMEI changed.
Is it possible to homemade sim unlock it for free ?
(sorry for my bad english)

Hi,
Long story!
I got an S3 from a friend who need help because it was very slow and whatnot, anyways, he also told me that this S3 is not from UAE but it's working fine here, just very slow.
I said well, I will install a UAE firmware and hard rest it, which I did but ever since, I get this NOT REGISTERED ON NETWORK.
I read every possible thread about this issue here and elsewhere and tried all methods like this one: http://www.youtube.com/watch?v=_Z6zTfe-sC4
None of it worked out for me.
I tried another Android firmwares (4.3 Etisalat UAE, 4.2.1 Etisalat UAE and finally 4.3 T-Mobile Germany)
The reason, I chose Germany is because when I did first the hard reset before installing the UAE firmware, the phone was in German, so I had to choose English.
Now, obviously something in the UAE firmware is not compatible with the phone, maybe modem, basband...I don't know.
How do I know which firmware to download from sammobile and from which country.
I'm not even sure that it's Germany! It could be Austria, Swiss and even Germany has many operators, O2, T-mobile, Vodafone etc......
Is it even possible to restore the phone to it's very original software after trying all of these Firmwares? I doubt it.
One more thing, from the threads I read here and there about this problem, this issue has to do with the IMEI but it's not my case I think.
When I hit *#06# I get a regular IMEI, nothing lost.
PLEASE HELP!
Thank You in advance
Take it back to your friend. It's either stolen and imei blacklisted or region locked now you updated it to 4.3.
Search and read to find out more.

This friend of mine works at the Norwegian Embassy and his phone he got it from the Norwegian staff there, but it was bought outside the country.
And he has been using it for over a year .
Anyways, I went to samsung and it's either software or motherboard because the IMEI is showing on the device meaning it's written on the software but it got corrupted on the hardware.
will see
waiting for their call
Motherboard
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
