IMEI changing is going to get you sore!

Many people often come up to me in the street and say, you look like a bit of a geezer (their words), do you know how to change my IMEI to clone that of another phone legitimately purchased within the state of my draconian governement?
I will typically retort with a chuckle, and then the following diatribe:
CHANGING YOUR IMEI IS VERY LIKELY TO BE A CRIME IN YOUR COUNTRY
Now, you may well be a pimp or snakehead already, so no worries relatively speaking, but understand that changing IMEIs can result in a prison sentence or castration, not merely a slap of the wrists. One way or the other, you won't be bending over in the shower if this is a crime in your country and you're found guilty. The law is there for a valid reason, if not necessarily a good reason.
Please check the law in your country before considering changing your IMEI.
You should note that in these days of heightened terrorist threats, if your phone is found to have a false IMEI and you also happen to have a beard and a beautiful tanned completion, you're likely to be spending time with wires hanging out of your orifices, so again, think twice.
I have no place to speak for the administrators or other moderators of the board, just for me, but my view is this:
The board is called XDA Developers. We develop.
The fact that you gets newbs, rubes and non-dudes on here is by the by; our raison d'être is to develop. That entails research and development, so for me, researching changing IMEIs may be a legitimate pursuit. Probably not, but maybe.
Next, recall that the administrators of this board researched and released pretty much the definitive solutions for IMEI changing, on older phones at least. That's part of the reason this board exists. I would be a hypocrite to jump on anyone else carrying the same flag. However, anything that will potentially get the board in trouble will be stopped.
So once again, lube yourself up well before considering changing your IMEI.
And please, be nice to each other, eh?

LOL! Vijay, I love the way you write! Funny but educational. (A little more humor around here would not hurt.) Well done!

Vijay,
If you have 2 perfectly working O2 Exec and I change the IMEI numbers to be the same on both then
1) What effect does that have if the phones have SIM's from the same service provider, if any?
2) What if the SIM's are cloned, will an incoming call ring at both the phones? Does having same IMEI have any effect here?
.....getting ready to be sore

Universal IMEI change
Sorry ,I can't use it in my Universal,any body can help me?

hi
my provider is ir-tci and it doesnt let the imei to be changed but i installed core 2.0 wm6 and after that radio 2.69.11 and it has changed my imei ... how can i change it back to original ?
thanks

I thought that was just me as the imei number on the phone changed too after i have run some unlocking software on it.
Dial in *#06# and the last four digits on my phone's imei number have changed from the printed sticker under the battery.
How have i managed this.?

I just checked mine too and I noticed that *#06# just gave me 2 more digits than what's printed under the sticker, so just double check the whole IMEI and I bet you find the same thing - just extra digits!

same here, missing the last two digits in my IMEI number after installing Radio 1.41.00.10

My IMEI number has 2 extra digits (than printed on box and under battery) it has an extra "04". Saying this I have never looked at it using #*06* before. It may not have been changed.

When you make a call or a data connection using your device the IMEI number is transmitted to the network. So they keep a track of what device your using when making calls sending sms's etc
1> same IMEI number will not be active at the same time on the network,
for example, if you make a call with device A and hand up then make a call with device B, thats fine, as the IMEI number will only be associated with 1 number at the time.
You will not be able to make 2 calls on both devices at the same time.
2> same thing here if the sims are cloned on say vodafone the network will pick up 2 different sim numbers in use and call will fail.
heres something I cam across when i worked for VODAFONE-
customer had a P900, which was reported as stolen- the handset was blacklisted-the IMEI number was barred on all UK networks- and a replacement device was sent out to the customer via there insurance cover.
The very same day the customer went into a Vodafone store and said that the device was not working. and wanted it swapped there and then.
Normally store staff comply without asking to many questions, but this guy was being arsey so the store staff member decided to follow producer and call us on technical support-
I was lucky enough to get the call- she explained she couild not make any calls on the deivce-
I made sure the account was active, all was ok on the network, the sim had updated onto the network and the network new it was activated-
I asked the store person what she experienced and she said just a single beep and thats it, she had full reception etc-
so i got her to do *#06# and checked the IMEI number, and it came up as blacklisted.
mmmmmm i asked her if it was a new phone, she advised yes the customer brought it in today and it had al the packaging-
I then checked the imei number against the calls that where made prior to the user reporting there phone as stolen, and guess what it matched.
so who can tel me whats happened here?
ok thats enough guess-
The customer reported his phone stolen, went to the cops reported it to them- got a crime refernce number- called vodafone put the insurance claim through, got his new handset in the post, took that out of the box, his old handset that was now blacklisted put that into the box,
was hoping that he would take it into the store, tell them the device was not working and they will swap it there and then, so he will have 2 working devices
naughty naughty
the shop staff, thanked me for my help and said this ha sput a big smile on her face.
what happend to this guy,
his account was blocked, he was blacklisted (that info is shared with other uk networks) and to top it off he woyuld have to pay the remainder of this 12 months contract.
he could say NO- but all Vodafone would do is, write of his debth and sell it to a collections agencey.
moral of the story-
If you be nice to people you may get away with what you want-
its not what you ask, its HOW you ask.
Whats my rambling abouve have to do with IMEI numbers
DONT DO IT - its not worth the prison time-
uk blacklisted phones will work in any other country other then the UK

My thinking thereon subject is different.
All depends what right is in data of country. It in my country be permissible then what right does not it forbid.
I spoke with two operator and they denied clearly that imei has with realization of connection some relationship.
It it in modern nets was used was only ID card of SIMAS and it telephone set.
It it was it is knowed was universally that ways exist in relays IMEI. Since it exists prepare it - it was not it been possible to unite IMEI and telephone.
I bought my telephone and can to make what it wants. How it wants to alter I have IMEI this prowo him to alter. I in instruction it have not written: Prohibition of change IMEI.
I in right it have not written : Prohibition of change IMEI.
I lost my telephone. He be found at police. in order to to get him I passed imei there now policeman said me. Imei could someone alter, pass different features which had this telephone. I answered him : scratch on casing, damaged catch from battery and sticker underneath, red colour. So policeman tells this it agrees. And my telephone gave back.
I understand that someone can take me telephone, to alter IMEI and to pretend that he his is property. Then truth. And it it should oneself do this because criminals were helped. It there now it it was not it been possible was to claim: change IMEI is crime. I alter XDA maniulator imei - whether means from I am criminal ? I created to change tool IMEI - whether I am criminal? How you will use him in aim the commission of crime you - are criminal then . if you have gun you - are killer? It ! If you will kill someone this gun then you are killer - and this is bad. this is difference.
You do not it understand maybe because my English is bad - forgive me.

hrm
how can the authorities proove that it was you who changed the imei though?
you might have bought a used phone witch had its imei changed by the seller without your knowledge for example

I'm in favor of any tool that lets us do what we want with our phones as I prefer a fully unlocked machine that will let me do exactly what I want with it. For that reason, if anyone knows of a prog that will allow me to do all these things on a G4 prophet (including change imei if I so choose) please post the links without any of this "search and ye shall find" nonsense. Please just show the direct links to all the tools needed and detailed instructions for the less technical amongst us.
I don't harm people just because I have access to knives or break the law just because I can. Nor do I do so if asked to by someone. We don't have to do wrong simply because the tools exist for us to do so, and the ability to change imei will not make us hardened criminals. It may help some who are unable to use a perfectly legitimate phone for reasons beyond their control in an unfair situation and that can only be a good thing. As for those wanting it for the wrong reason, they will find a way without the help of this forum and it would be very naive to think otherwise. Where profit is concerned a criminal will always find a way and this forum will make little difference to that fact.
This is a developement forum and I would prefer to see it remain so without entering into off topic arguments. I also don't like to see people advertising anything for profit as it negates my own reason for being here. This forum has rescued me numerous times in the past at no cost and I am only too willing to return the favor if ever able without payment. A pity others seem to see it as a free advertising medium.
XDA Developers has always improved things for me and will hopefully continue to do so. its a pity the roms which made things better in the past have now gone and I don't want the same to happen to the free tools still being developed which give us the control we deserve for our own equipment.. The more the merrier.

Hello guys,
Don't worry if the first 15 digits are the same with what's printed under the sticker... Extra 2 digits represent the software version of the phone.

Pinesio: generally we don't mind discussing techniques from a hacking/development POV, but the problem is the illegality of aiding in changing IMEIs in many jurisidictions.
There are well publicised apps on this board already, some open source, some which we all helped to write, to change IMEIs. But, those members that like to watch their ass or are relatively easy targets tend to stay away for fear of getting on the wrong side of the law... But generally, I'm all up for seeing where hacking can take us with the device that we paid for - within legal boundaries when in a public sphere.

..the reason it's illegal is that mobile phone theft's really common - at least in the UK. you can now get 5 years in prison for IMEI changing here. reasoning is that the networks have worked out that if they block the IMEI number of stolen phones, they become worthless. let the scallies work this out, and eventually mobile phone theft stops, i guess.
now, if you were to change the IMEI number, you could then unblock all these stolen phones...this is why it's illegal in many countries.

The only country where you *might* have a legitimate reason for changing an IMEI is Turkey. If you are a Turkish resident and you baught a mobile phone outside of Turkey then your IMEI will get blacklisted by the Turkish networks because of some stupid law. Changing the IMEI to your old and unused phone would get around this.
It's probably illegal there too...as are a lot of things in Turkey...like free speech for example but that a whole different debate.

T-Mobile Desire: IMEI on phone does not match on box?

To those who have the T-Mobile HTC Desire, is your IMEI number on your phone the same with the one on the packaging box? Mine do not match

LOL, where did you get it from? the official t-mobile shop or some retailer? I think you should contact them asap in case of further misunderstandings

You need to ask T-Mobile about that, I would be making sure that I had matching Box and Handset IMEI numbers, unless they can give you a very good reason why they are different?

I got it on Saturday from T mobile (upgrade). I just realised lol will call them

or they tell him it doesnt matter and the IMEI of the phone is the same with the one in their system

My IMEI matches so no problem here.

some operators can track the phone by the IMEI, so i guess if your phone have been stolen and went to the police station or the mobile service provider for help so they can track the mobile for you, the first thing they will ask is to see the IMEI and prove that its yours, probably through the package
so go to them and tell them about the mix up, atleast if something happened later on, you would have already mentioned it.

Just called them and was told that they are gonna send me a new phone apparently. They are gonna call me back soon. Oh wells!

i think i may have bought a stolen phone, please help

hi, i have recently purchased a touch pro 2 off ebay and i stuck my SIM card in it to find out i cant get a signal or make calls etc..
i really dont know what i should do.
please help. any advice is helpful.

Was it used or new?

used, he was selling as 'it no longer makes calls or sends texts'
if it was listed as barred theres no way i would have bought it. but with what he wrote it sounded fixable.

So you were suprised when you got it that it doesn't make calls? Call you provider they might be able to unlock it if the phone isn't broken to begin with. Next time i suggest understand what you are buying because this is a pretty ridiculous post. I am questioning my own judgment for even answering to this post.

i wasnt surprised it didnt make calls, i thought he may just have a bad radio or something but i checked the imei on checkmend and it shows up as blocked..

You bought a phone that the seller told you didn't work. You assumed the reason it didn't work was one thing, but it turned out to be another. Whether he lied to you as to why it didn't work or not, you still took a chance on buying a phone you knew was not working. Take your loss, learn from it and move on.

If the phones blocked then he has found/stolen it. Or put in an insurance claim saying it’s been lost/stolen.
If you paid by PayPal put in a claim giving reason that you were not told the phone was blocked. You will then get your money back.

I've had this situation before and although it turned out that the phone I had purchased wasnt stolen, the process will be the same:
Contact your Phone Network and give them the IMEI number and explain the situation. Don't worry - they are used to dealing with this type of call. They will use a database shared between all the network providers to find out the original and current owner of the handset and tell you whether it has been registered stolen or just blocked by the previous owner (this is what happened to me only I found this out a lot later).
If they tell you it is stolen, take the handset and everything that came with it to your local police station, including print-outs of any correspondence you have had with the seller - via the website market place or direct.
The police will give you a crime number and most probably take the device and the print outs from you to investgate further. You will need the crime number to get your money back later on.
Contact the market place and your bank (credit card company) and explain the situation and give them the crime number.
In most situations, the market place will give you your money back (withdraw it from the sellers account). If they dont, your credit card company will do the chasing for you but you'll need to try yourself first.
The market place may ask you for more documents from the police and the police will be very understanding. The police woman assigned to my crime number was very helpful and was in regular contact with me about how the investigation was proceeding.
The whole process may take 6-8 weeks. It can be drawn out but persevere and you will get your money back - and deservedly so.
Good luck and PM me if you need any further advice.

I am no expert but they can certainly be blacklisted by the owner and that was what I was suggesting.
http://www.unlockme.co.uk/blacklist.html was a site I read up on when I was faced with the same situation.

My phone was blocked. I rang up Orange and told them the situation and they unblocked it - to my surprise. At the same time, I had opened a case in eBay which went in my favour, but I decided to keep the TP2 as it's now working. In my case, I could get a signal (four bars), but it always came up with no connection.

[Q] SGH-M919 Black Listed (Please Help, TIME SENSITIVE)

(Please Help, TIME SENSITIVE)
I need help please, I post adds on CL and buy/sell the items on fleabay. I usually don't check the EMEI or any other numbers and have been fine until now. I was under the impression that if the phone is black listed, unlocking it would fix the issue... Am I incorrect??? If not, what can (besides refunding the $$$), be done to the phone to make it work on the T-Mobile network? IF unlocking doesn't correct the issue?
Thank You, in advance for your help everyone...
My correct Email is [email protected]
The yahoo Email that is attached to this account is abandoned, and I can no longer access it.
The Control Panel will not allow me to update my email. It states that the email is already taken.
So I believe I have two accounts on this site. I've already messaged XDA about the issue

I don't think there's anything legal that can be done if T-Mobile has blacklisted that IMEI, besides it maybe working on another Carrier? i.e. ATT but I don't know about that.
I think your chances of getting it work on T-Mobile again are in the neighborhood of .01%

Yeah if it's a T-mobile phone and T-mobile blacklisted the phone, it will NEVER work on T-mobile. Sim unlock might or might not work on another network such as AT&T as I've heard they now share blacklisting. Might work overseas.
Refund the money, get it unlock to see if it work on AT&T, resell it on CL/Fleabay and make sure the listing shows that it's a BL T-mobile phone.

Was It pass due account?

no unlocking it wouldnt fix the issue, once the phone has its IMEI blacklisted, the only (legal) way to get it whitelisted again is for the prvious owner is pay off the phones balance, and thats only if the IMEI was blacklisted due to not paying the bill. If it was blacklisted because it was reported stolen, your SOL.
The only thing you can do, is unlock it and try to sell it as an unlocked device. But other then that, you will not get what you payed for it, due to it being blacklisted on a carrier.
Always gotta check those things on craigslist, people always think "it will never happen to me" untill it happens to them

Unlock it and use it on Att

this isnt a good idea, in your instance, it was their mistake in the first place. The op's situation, what more then likely happened is that the seller of the phone sold him the phone, then reported it stolen. If its reported stolen, they arent going to just "reinstate" it

[Q] Newbie here - unlocked i317 "MM#6 Phone not allowed" for overseas network

[Q] Newbie here - unlocked i317 "MM#6 Phone not allowed" for overseas network
hi all,
I'm new to this forum and its great to be associated with such a wonderful group
I bought an unlocked AT&T note2(i317, android 4.1.1 and firmware- i317UCALJ2) off ebay.com and got it to India a month back from WA.
I have been trying to configure mobile network on Indian carriers but always got these errors :
- " your sim card doesnt allow connection to this network" and "MM#6 phone not allowed"(MM#6 appears only since yesterday)
- the network bar(i.e. signal strength icon on home screen) doesnt capture the local networks at all which is quite surprising.
- Phone's IMEI(35700..) doesnt match IMEI on the back panel(35542..)
I heard about cases where phones purchased from ebay/craigslist getting blocked ( for example, http://forum.xda-developers.com/showthread.php?t=2341622) but I guess that shouldn't stop it from using overseas? Also, I heard IMEIs of such blocked phones look like "null", "0"s etc. but IMEI of my phone looks good and doesn't showup in the list of blacklisted IMEIs on swappa or CheckEsnfree. Lastly, I also checked the GSM bands of i317 and they are definitely compatible in India.
Can someone kindly help?
Many thanks in advance.
Chaitanya.

I would like to add that I have tested SIMs from multiple carriers but failed to locate networks and APNs. All other features like WIFI, Bluetooth etc are working like a charm so I suspected if it got to do something with the IMEI.
I request some guidance from the experts in pointing to the issue so that I can try the workaround(Sorry..Im a novice at troubleshooting android )
Kindly let me know or redirect me to a forum if already exists.
Thanks,
Chaitanya.

The good news is your phone is clean stock.
The bad news is your phone is blacklisted, and the IEMI was hacked/changed.
The only legal way to solve this is to contact the original carrier (I'm guessing AT&T USA), give them your IEMI, tell them you bought it legally in the USA, and ask them to unblock it. The blacklist is all US carriers and their overseas versions, all European carriers and their subsidiaries. Like Orange or Voda or t-mobile.

My bad..I should have checked the status beforehand in detail. Till now I was only aware that bad IMEI phones arent allowed majorly in US only (saw many such phones being sold on ebay intended for international use ).
As far as I know, i317 is only the at&t version of note2 in US and it differs a lot from its International versions (gt 7100, 7105 etc). Do you still think this blacklisted issue holds good in countries where i317 isnt available?
Since sending the product back to US is highly unlikely, can you kindly let me know the best way I can get the issue fixed?

Answered in my post above. From India you can probably use the tech chat from AT&T website.
It's a blacklist of disallowed IEMI's so the model is irrelevant.

Thanks Rangercaptain for your clarification. I tried AT&T's live chat but it seeks registered contact details to login. Is there any email support?
Not sure if these kind of questions are allowed here but I heard there are tools that help to retrieve lost IMEIs (which work on rooted phones).
In case it gets tough to get hold of AT&T, can I try any of such tools on my phone since it is not registered in my county anyway and doesnt come with any warranty?
P.S:I know changing IMEI is illegal but I guess retrieving it is not :fingers-crossed:

I started to think may be the motherboard got changed(since S/N also looks different and the phone looks absolutely new with no wear at all)?
I'm being forced to think that IMEI is clean because some followup with AT&T and US Samsung care have confirmed that the phone's back IMEI and S/N are definitely good with warranty till 2015 and don't show up in any of the blacklisted lists.
I'm sorry for posting different questions but please note that I'm not much aware about this phone's history and I'm trying to openly share the results from my extensive findings. Thanks!!

If you're sure everything is clean are you sure your Sim card is correctly provisioned for the network? The easiest way to find out is to trade cards with a working phone.
Before you think about trading main boards (I did that because the gps connector was broken) go to www.mobiletechvideos.com and see what they can do for you.

Yes, I have been trying this on a working sim with an active data plan which is currently working on my xperia.
Over the last 2-3 days, I have learnt that flashing a wrong ROM sometimes might corrupt EFS folder that stores IMEI,serial number etc., and reinstalling firmware through ODIN(which requires to download original stock ROM separately) or KIES software might restore the lost EFS folder.
I thought of giving this a try and accordingly reinstalled the official firmware but without any success.
Can someone redirect me to any such guides/threads that might help? If it doesnt happen then I would like to close this thread and create a new one for EFS related troubleshooting.

If efs is corrupted there is no s/n or imei shown. It displays null
