Blacklisted IMEI/MEID (bad esn) phones can not be repaired by the user. The imei blacklist is an international list which all gsm carriers have access to. Once the IMEI number of a phone is blacklisted, no gsm carriers will activate the phone on their network. Changing the IMEI number is the only solution but its illegal in some countries (check your local regulations). Even if its legal in your country, you can't (afaik) change the IMEI/MEID of the M7 because there is and encrypted key stored on the phone memory to check the authenticity of the IMEI number. If the key doesn't match then the radio will not turn on.
Best you can do imo, is to sell it as is (bad esn)

bought my diamond second hand off some guy 2 months ago..

and today when I was looking into unlocking my phone, I noticed that the system IMEI is different from the IMEI label on the back of the phone.
I am using a deep shining ROM. did the ROM flash over the IMEI or was my phone just messed up to begin with?
also is there a soft method of finding out whether or not my phone is already unlocked?
Sorry to say but that guy messed your over by changing the IMEI. Flashing a rom doesn't do anything to IMEI, special tools and software CAN change it, and that is what this guy did. You can't do anything to change that, as changing IMEI is downright illegal and you dont want to get caught up in that.
As for finding out if its unlocked, take another companies SIM CARD, ie if you are with ATT, go and get a Rogers, or whoever else uses a SIM CARD, and find out if it will work in the phone.
so, it is quite possible that this phone is stolen? damn... what are the potential consequences of that? if he switched the original IMEI to the current one that I have, what if someone legitamately uses the imei on the same network, am I going to be screwed?

No you will not get screwed. {Unless you really want to; then I'm sure we can arrange for it}
IMEI {International Mobile Electronics Identification} Numbers are uniqe to every phone, but the network does not {& I believe Cannot} read the IMEI. ESNs {Electronic Serial Numbers} are a different thing, as the CDMA networks use this # to Identify the devices network authenticity {in other words: Whether or not it's authorized to use the network}. GSM {Global SIM Management} Phones rely on the SIM card to authenticate the devices access to the network. An IMEI is never sent thru the network! That's like posting your social security # online {Mine's 420-69-840} About the only time that a false IMEI is a problem, is when you need to get it unlocked {as you are trying to}; or if you need to report it stolen/lost. If the latter is the case then you will need to provide the authorities with both IMEIs. This is in case the person that has it removes the label in the back. For unlocking the device, you need to give the # that's in the software; as this is the only # the phone knows. Oh yeah, You can't send it in to get HTC warranty service either
Have you tried asking the person you bought it from about this? I would!! I would want to know why he did it, how he did it, & where the other # came from. It is a possibility that he had replaced the Mainboard with another unit, but he should have changed the labels at the same time. I have done this with a few phones {combine a couple bad ones to make a good one}, but I always ensure the IMEI or ESN matches on the back & in the software! If you believe you were defrauded, then contact the authorities & explain it to them. If there is another phone with the same IMEI, they should be able to tell you.
It might either be that he changed the main board or the cover itself.. (hopefully he did not steal it..)
I wouldnt worry too much about it though. Just go with the IMEI that is displayed on your screen not on the back of the phone.
well i tried to get an unlock code by using the IMEI read off the system page on my diamond and the guy couldnt get aan unlock code; is there anyother way to get the correct code>?

Hi,
Maybe it is or it isn't (but it is possible). It depends on which country that person bought this phone and maybe he used warranty service. I had this issue myself.After 2 month My Diamond didn't recognize my simcard, i sent it for warranty and when it came back GPS didn't work. so i sent it again , when i received it, at repair center they said that they replace mainboard, so imei changes and i received written document that they replaced mainboard (my back panel imei and the imei that phone shows are different now).
for checking it , Goto this site : http://www.numberingplans.com/?page=analysis&sub=imeinr
enter both imei and check them, if both are for diamond i think your mainboard is changed before, but if the imei that phone shows is belong to another handset (for Ex : a nokia one or another htc model) i can say 99% percent your phone is stolen.
i'd probably bet he's bought an "original" housing from auction site. i've done it many of times but i usually rip the imei sticker off, bear in mind the imei on the diamond is only on a metal plate, he may have forgot to change this part, he may have damaged his old imei sticker/plate, as stated above he may have changed his main board also, there is many possibilities.
don't worry about it, if your still a bit worried try the CheckMEND online service here:
http://www.checkmend.com/uk/
It costs £1.99 per go, (which you'd want to do both imei's) but you get a certificate telling you wahts dodgy or not about your phone.
it a great service if you feel a little worried.

[Q] Stock Note 3 lose Unlock after Sent back to Repair

Hi to all
I have a Stock AT&T Note 3 on KitKat, And I bought the unlock code from a website and the Code was working fine
I sent my phone to the Samsung repair center in TX to fix the memory card slot problem.
After a week they sent the phone back to me, and Of course the phone is back to the original settings
When I turned on the phone and inserted my T-mobile Sim card, the phone is asking me for the network
unlock code, so I entered the same code that I used before and it is not working ...
Thanks
You probably didn't get the exact phone you sent them. They probably sent a different one. Check for an old receipt, or the original box for the imei code. See if it's different then the new one. It most likely is. If it is, you will need to obtain a new unlock code.
I checked the IMEI number and they matched
I also thought of that it might have to do with the unlock code
so I ordered another Unlock code from a different site
and it turned out to be the SAME Unlock code from the other site !!
Yes there's only 1 unlock code per imei. It doesn't matter where you obtain the code, it will be the same.
I hate to tell you this, but you'll need to contact the warranty dept and probably send the phone back. Again :'(

Do you think this has anything to do with the Region lock restriction ?
No I don't believe it to be related to region lock.
Check one more thing for me please. Verify that the imei of the phone is what you believe it to be. Open settings and in "about phone" check under status and verify the imei is what you think it is. You can also Press * # 0 6 # on your keypad, Press 'Call' or 'Send' as if making a call. Your IMEI number will be retrieved and displayed on your screen.

do you know anything about this ?
NOTES: If you have a Samsung Galaxy S3, S4, Note 2, Note 3 or your Android version is Android 4.4 (KITKAT): All SAMSUNG devices manufactured after the date of JULY 2013 and Samsung devices running on Android version is Android 4.4 (KITKAT) are subject to REGION LOCKING. If your phone has been used previously with the original carrier, this will not apply to you. However, if your device is BRAND NEW, your must activate it with the original carrier. If your Samsung device becomes Region locked, you will not be able to fully factory Unlock your Samsung devices so it can be used internationally. Even the correct code will not work anymore. In order for your Samsung device NOT to be region locked, you MUST activate (FIRST USE) your S3, S4, NOTE 2, NOTE 3 with your ORIGINAL carrier at least ONCE to take your region lock OFF. After your Region lock is off, you can Sim Unlock your device via Unlock Code. All Canadian Carriers are NOT subject to Region Locking. All USA and European Carriers ARE subject to Region Locking. Region lock is removed automatically after you activate your device with its original carrier. Make some calls before unlocking. (Insert an active original sim card into the device and make a few calls to activate the phone and bypass the region lock. Once you've activated the phone, you can input the unlock code.)
Well after reading that I'm amazed. I believed region lock was based on where you lived and used the phone. Like a person in Europe couldn't use an at&t phone overseas until it was used in the states. I was unaware a person in the U.S. had to do the same if they were using it in the U.S. but with a different carrier. My apologies.
You wouldn't happen to know anyone on at&t would you? Maybe a Samsung rep in bestbuy can help you with borrowing an at&t sim and making a call or 2 on your phone.

I tried to use someone's ATT sim and it doesnt work
Also Samsung is telling me that "as you have unlocked the device from third party site , and this is not considered as official unlock for the device"
I might bring the phone to bestbuy and let them check it out.. since the phone is still under Warranty
There's defiantly something wrong if an at&t sim doesn't work. Are you the original owner? If not do you know the original purchaser? It could have been blacklisted.

The phone is working Fine with an ATT sim card, it has signals
it is just that it is not working after I inserted my tmobile sim card
and entered in the unlock code... So the imei should be fine !
I believe you need approximately 5 to 15 minutes of use on an at&t sim card from my previous readings of other user experiences.

Having two different imei numbers!! Like really!

Hi guys, recently i bought a T-mobile galaxy s6 from craigslist, i checked the imei and it was clean nothing wrong with it at all.
The phone is completely stock not even rooted. But the thing is the imei number under the settings is different than the one underneath the glass cover in the back. Both imei numbers are clean. The phone is locked right now and i can't use it for my at&t number. I talked to T-mobile customer service and they said that the phone should be unlocked with the imei number on the back of the phone. But when i gave them the imei number from the settings they said that it is invalid and won't show up in their system or data. So, I called Samsung and they said they won't be able to do anything at all, i just have to call T-mobile, but T-mobile is telling me to call samsung, and its just going through a cycle a stupid one. Both are knows for bad customer satisfaction and it is true.
Please, anyone have any idea how to unlock the phone? or overwite the imei number to return it back to the original one! Both companies won't help as they don't know what to do. I am sick to the bones of being a customer for both. BTW the device unlock app thing by t-mobile did not help the issue. it says can't recognize the device

There was a guy on here named Stilfilz i think was his name. Maybe ask him.
Possibly the IMEI tmobile cant find in their system can be a metropcs galaxy s6 IMEI which is also sm-g920T hardware.
good luck

yeah i was in touch with the guy last night, but sadly the flexihub did not work on my computer we tried many times but no luck i always get no internet connection even though the internet is working . Do you think if i flash a metropcs stock rom it would help unlocking it? i think the phone is refurbished thats why i have a different imei number.
when i looked up the imei under the settings, i checked online for the imei and it says for model number SM-G920F ? should i flash a stock rom for that model number or what
Quick update ....
So I flashed a galaxy s6 AT&T stock rom 6.0.1 and its working fine. No longer need the t-mobile device unlock app, but now i am to the point where it asks for the unlocking code.
Should I purchase an unlock code online using the imei number the one from the settings?
UPDATE:
Thanks to Stilfilz , i flashed the stock rom then rooted it, then Stilfilz got it unlocked. Took only 3 minutes. now it is working with an AT&T sim card with no issues.
Hi, i have the same problem with my galaxy S6 edge, the IMEI number under setting is different from the one in the back plate. if you have a way to fix this please please email me at [email protected]
Thank you.
Please help me with this issue, i tried to flash it with original ROM using Odin, but no success. Any input would be appreciated. Thank you

IMEI locked by the operator

Hi,
sorry if the question was already placed but honestly I wasn't able to find a unique answer.
I'll try to be direct:
- phone HTC M7 Vodafone branded
- the phone is working correctly but it has the IMEI blocked by the operator (Vodafone) due to the fact the owner didn't execute all the payments related to the contract. So Vodafone blocked the IMEI. I'm very sure about this as I'm sure it isn't a stolen phone.
Ther result is (as you know) the phone can't work as a phone (no call, sms, data via mobile)
That said, is there a way to unlock the phone in order to work again (as a phone indeed)?
Please don't close the topic immediately, at lest an answer, many thanks

If the first owner didn't made all the payments then it's a stolen phone. Doesn't matters if it was stolen from someone of from a company, it still stolen.

It can be illegal in some countries to mess with the IMEI. Iirc, if you manage to change the IMEI there are other mechanisms preventing your radio to be turned on with a modified IMEI on this phone.
Looks like this topic is not welcome on xda (and for good reasons):

If someone sold you this phone without mentioning it was blacklisted then it's a fraud and should take the required actions to report that fraud.
Thanks Sir

Carrier Sim lock after Samsung repair

So I bought a Sprint Note 8 (SM-N95OU) that was unlocked from eBay over a year ago. We use T-mobile for our service. Everything was going good until the phone would no longer boot up due to draining all the way to 0%. Called Samsung and they did a free replacement outside of warranty.
So now that it's been repaired it is UICC SIM carrier locked.
Under UICC unlock it says "your device is locked to Sprint SIMS only." A message pops up and says to contact sprint. I contact sprint and give the IMEI and they said I have to contact the owner. I assume they never unregistered it from their account.
Is there anyway we can go back to using the phone? I mean we paid for it and feel like we own it but according to the software it does not seem to be the case. Lol.
Will putting a Sprint SIM in unlock It? I notice it doesn't ask for a pin and I think I read they are unlocked via a signal. That signal would have to be resent or would communication on the Sprint network alone unlock it. Not sure If somehow it will know to unlock itself once it connects to sprints network?
Anyway any help or direction is appreciated. Not sure if I need to sell it to a Sprint user and get a different phone now.
Well I just paid somebody on eBay 10$ to unlock it. So far so good.
I had a very similar situation whichresulted in weeks of back-and-forth communication between Samsung and Sprint advanced technical support. Which that department is a joke in and of itself but the actual solution to my problem was just to insert an active Sprint SIM card into the device and then have them unlock it.
