Unlock Galaxy S3 - Galaxy S III Q&A, Help & Troubleshooting

Hi, i have a SGS3 and the carrier have locked the phone thou i bought it in second hand. With receipt and it was brand new in unopened box. Worked fine untill couple of days ago when it got locked.
So i'm not able to use the phone cause i cant get no network.
I rooted my phone and deleted the "efs" files so the imei changed but it didnt help my, still no network signal. Cannot connect.
Is there any way to unlock my phone? Please help me get my phone working. Payed about 450 euros for it.
Sorry if i put this thread in a wrong section. Newbie here..
Appreciate the help!

Take it to any phone unlocking shop or kiosk and should cost around £20. Im not sure the currencies exchange rate.
It may also be cheaper where you are from

Why the hell have you deleted the efs folder?. In the efs folder your imei is in.
Restore your phone if you got a backup of the efs folder. Otherwise use the search function in this forum. Because more people has done the same thing you've done

Are you sure its not been blacklisted maybe by accident... amd congrats on deleting efs folder big mistake
Sent from my GT-I9300 using Tapatalk 2

I saved the efs files so it's okay. I have restored them.
I deleted the files in the efs folder to get new imei number so i can pass by the lock on my phone, but it didnt help me.
It's maybe imei locked, dont know exactly what it's called.
Does anybody have any idea what to do to unlock the phone?
Thanks

Yes as my previous comment stated, go to a phone unlocking shop/kiosk and get them to unlock it. Really cheap and much safer than messing with it your self.

I think you have missunderstod me.. the phone is not locked to a specifik carrier. Thats not the issue. My phone have been blocked/blacklisted or whatever you call it in english.

Blacklisting usually means stolen goods. That's why you should never buy such expensive stuff (if "unopened" or not) from unreliable third parties.
You can't change the IMEI. Deleting the IMEI will give you the default IMEI which no carrier accepts anyway.

Think you've been conned mate. Try and get your money back is all I can advise.
Sent from my GT-I9300 using xda premium

Yes i have been conned.
There must be any way to fix it, like change the imei?

Oh i understand you now. All i can advice is maybe still taking it to a phone repair shop and seeing if there is anything they can do.
They is no garantee to fix any problems but i dont think it will cost you anything for them to have a look at it for you.

Dont think phone repair shop can do anything. Think the solution is here in XDA.
Heard that i can go to a local electronic shop and "take" the imei nr from the demo phone (by sdcard or blutooth maybe) in the shop somehow and use that imei on my own phone?
Or flash/rom root or whatever.. just want my phone to work

As I understand it, the emei number is hardwired into the phone , here in UK, it what the carriers use to block stolen/lost phones. I think it illegal to unblock. It also illegal to have the equipment to do this. The only way round I have heard of is a new mother board.
Sent from my GT-I9300 using xda app-developers app

Does it ask you for a Network locked pin or what comes up when you start your phone? , maybe you can use Voodoo to unlock it

asking about changing the imei is a banned topic on xda it's like warez it is fraudulent and discussion of it is banned
Sent from my GT-I9300 using Tapatalk 2

It is definitely VERY illegal to change the IMEI in the UK.

A IMEI block would indicate the phone has been reported stolen/lost. Think u been conned. Try n get your money back.
Sent from my GT-I9300 using xda app-developers app

Yes i have been conned, and no i cannot get my money back because i bought it in second hand, but brand new with the recipt.
The phone doesnt ask any pin or anything like that. I have signal bars but i cant connect to any network.
Whats voodoo?
Maybe it's illegal but it's also illegal to con someone but it happend. What should i do now? Sit with a 500 euros worth phone with no usage? F*ck that!

What country u from? Where did u purchase the phone?

yeah when i was talking to them i told them all about the problem and that i tried all the soft resets hard resets etc. and they looked at the phone imei and if i wanted to get it replaced by tmobile i'd need to ask the person i bought it from to transfer the insurances but i didn't save his number. so they said the only other option i had was to call samsung, and they did like a factory reset and it still didn't work.

ODIN back to stock ROM. Back up your apps using Titanium Backup, and copy that folder to your computer.
That way, when you get a new phone, you can have all the apps.
Or use ROM Manager, back up, get those files to your computer, and flash back to Stock ROM.
but idk for sure. Just trying to help.

IMEI block + "not paid" = .... (go figure)
There is only one reason phones gets lockedout by IMEI, if it's just the bill for the contract that isn't paid they block outgoing (and eventually incomming) calls and all.
Hi
The only way a phone will get blocked is if the owner reports it being stolen/lost and not for unpaid bill.
You could be a victim of crime if bought on second hand market as the owner is probably doing insurance scam.

I don't think anyone here is going to help you unlock your stolen phone, no matter what kind of excuses you come up with. Perhaps you should have the decency of returning it to its rightful owner, the one that actually did pay for this phone.

This smells fishy to me too. They dont block the imei...they block the service
Strappin on my LOLLERSKATES
The only reason an IMEI will be blocked is because you stole the phone from someone else. Or you reported it stolen. Full stop, nothing else to say about this, at all, ever.
It is called Blacklisting.
Therefore, if you come here to this very resourceful community who operates within the bounds of legal framework that we live in, looking for a way to change the IMEI, which is considered a Federal Offense in the USA, and in the United Kingdom, under the Mobile Telephones (Re-programming) Act, changing the IMEI of a phone, or possessing equipment that can change it, is considered an offence, you will be dissapointed.
I would recommend you either contact your telecom company and explain you found your lost phone, or you return it to the rightful owner, or you use it as a wifi only device and feel guilty for robbing someone of their galaxy S2.
Ahaaaah u just dont get it a? Are u sure about what are u saying? U know that when u say something about someone it is good to be right because can go very bad for you with the law.
The phone is mine i got bills from this phone and i know what i am saying but i am not sure about YOU...and if u going to say something more about this ...not good.
So...anybody knows something helpfull?
thank you

I have never ever heard of any mobile operator blocking the IMEI of someones phone because they have not paid the bill it simply does not happen period, therefore it had to have been blocked another way.

I would also urge people to excercise extreme caution when buying mobile phones (or indeed anything) on the Gumtree website,a scammers / crooks haven, a common theme is for someone to advertise a high end phone like the GS2 for slightly below the going rate, usually the seller will call you from another number other than their own,they will say the phone is unlocked,brand new,etc,etc it is only when you ask them to present a receipt they will try and fob you off with excuses like "i need this receipt for my records" basically what they do is, person buys the phone, it is a real phone and everything works, a week or so later they report the phone stolen and put in a claim for another one, meanwhile your left with a phone which doesn't work as the IMEI has been blocked and you've no comeback, you try and contact the seller but find the number is turned off so basically your fu***d.

Can't happen, nowhere in the world phones are imei locked for not paying bills. That happens in some countries when owner of the phone reports it lost or stolen. By your username i assume you are romanian and just for the record phone providers in Romania don't use/need phones' imei , hence they can't lock it. So you might as well post what country and provider did that, but i guess if you do that everyone else will find out you lied, not that we wouldn't know that already
Quite easy actually.
Step 1: Buy the phone.

[Q] Change the IMEI

Hi
i have i9300
how do i change the IMEI number?
Thank you!
You can't. The IMEI is stored in read only memory so can't be changed like old phones can.
Changing the IMEI is illegal in most countries and I don't think it's possible on the S3 right now without having a second S3. Why do you want to do it?

In the UK the whole point of an IMEI is for national security. It's a criminal offence to change or tamper with it and you could be fined or imprisoned....if you like prison food or penis go ahead lol
Sent from my GT-I9300 using xda premium
The only reason to change an IMEI is if you stole or bought a stolen phone and need to change IMEI because networks are blocking that phone, and i'll bet there's thousands of people bought a phone from Ebay only to find the thing network blocked and want to do this cos don't want to waste their money they spent by reporting to police.
I love seeing these posts, every time OP gets shot down. Have fun playing with hot property.
Backup the efs folder to ur computer or somewhere, then delete the folder of the phone

Unlocked S3 ..Serial Number " Not available" ??

I purchased two samsung S3's but unlocked, i bought them on craigslist and am now a little worried. I notice that under status, it says that the Serial number is not available?
Why not? Does that have something to do with unlocked phones?
I took the phone to ATT and they put a demo sim in there, it said it was on the ATT netowrk but I could not call anyone, the ATT salesman said that it was because the SIM was a demo, sound true?
I also went to TMOBILE and put a sim in, and it said it was on the TMOBILE network but did not try to make a call.
What do you guys make of this?
i just put my tmobile sim in it and i can make calls, but absolutly no internet
Mine is unlocked and I have a serial number.
I did a little more research and this is my problem now.............. http://forum.xda-developers.com/showthread.php?p=32694323#post32694323

I have a question regarding a Samsung Galaxy s3.

The question is I bought a sg3 phone for $400 on a market here in my country. But when I activated it with the same carrier the phone is from. It appears that the phone have been reported stolen and also the phone is unlocked for any gsm carrier. My question is since I will not be able to use it on at&t which is it original carrier will I be able to use it on t mobile network since its diferrent and they use a different network?

Have a look at this from T-Mobile, AT&T were already doing it, IMIE blocking blocks the phone across all network in that country, you could probably use it abroad normally as its not on a US network but using in the US unlikely

Yes but you get the far bigger problem of illegal imei changing which can get you intr real deep trouble.
Also, imei cannot be changed easily, only transplanted.
Note that most "stolen" devices are not stolen per se (they often come in original boxes) but are insurance claims.
