[HELP] Restore Bad IMEI 004999010640000

I bought a 2nd hand galaxy nexus and just notices the IMEI is 004999010640000 which doesnt match with the one on the back of the phone. How can I restore it? thanks

does the IMEI reflect back to the carrier? If it was called in lost or stolen and I put a sim in the phone with out changing the imei with verizon will it work?

This is generic IMEI and most likely means that phone was originally sold SIM locked for specific carrier. Until there's a shorter howto/app, see here for details and how to get rid of it:

Yes, IMEI is reported to the carrier and can be blocked, effectively making your device unusable as a phone. Generic IMEI above for now works in the US, but it's blocked for example in India.
IMEI is also reported to google, as can be seen from dashboard. Would be fun if they started to track & block stolen android phones...

I have been using it for a month but until today i wanted to try it out on the original carrier so I noticed it didnt work... Then I checked the imei and saw that it doesnt match. thats why i want to go back to the original IMEI so I can use the phone on the original carrier

Serial number in software not the same as in back of phone

Hi guys.
I did yesterday the swap from yakjuxw to yakju and today i wanna check if imei number etc stayed the same.
Imei number is prectly the same as inside the phone behind the battery,but the serial number is different.
I dont know if this was before te swap to.
Anyone has a clue?

I also have mis-matched serial numbers.
Does anyone have an answer? If not, could someone at least check to see if the serial number listed under Settings is the same as the one printed on a sticker under the battery.
I bought my Gal Nex used, and don't know the history. From build.prop, it shows yakjuux.

That's pretty interesting I looked at my serial number and it also differs from that on the back of my phone.

[Q] HELP! Recovery of Sprint GS3 original IMEI after stupidly changing it with DFS

I flashed my GS3 to boost mobile. Long story short, I used a boost evodesign4g as a donor, I changed the correct values to get it activated, but I also changed the IMEI with DFS to match the evo design4g (never thinking to back up my original gs3 imei let alone write it down:crying:). I figured out at a much later date that I never needed to change my IMEI to match the evo design. Now I am switching over to voyager mobile as they allow byod sprint devices, so I can have lte. BUT ONE HUGE PROBLEM, Currently my GS3 has the wrong IMEI.... I need to recover my original sprint GS3 IMEI as it is linked in the sprint database to my meid and ICCID for LTE activation. Yes I have checked the obvious, I searched the forums found nothing for my situation, it’s not on the white sticker on the back I don't have the original box anymore because if I did I would not need to ask for help...I figure it might be similar to recovering a Verizon GS3 IMEI, Maybe the original is hidden in one of the NV items?. So does anyone know how to recover the original factory set IMEI for a SPRINT GS3??? Is there a way to calculate it from the ICCID number?
Thank you to all who reply! I’m really in a bind here and need some help or guidance.

[Q] Help with imei number

I purchased a phone off CL. I tried to put a SIM card in but it doesn't recognize one. So i realized the IMEI number on the back does not match the IMEI number in android OS. It doesn't say 000000 or one of those fake IMEI 049 numbers. It just has another IMEI number. My question is, is there a way to modify the numbers to match the IMEI number i have on the back of my phone?
I actually didn't know it didn't match until i sent it to samsung to fix. I thought it was just a problem with the SIM tray but they stated that the IMEI numbers don't match. As a result, they just sent my phone back without fixing anything.
Please help me out. It's on stock rom and not rooted
Again.. the phone is not blacklisted.. I want to change the IMEI number (software) shown in android OS to match the IMEI number (hardware) that i have shown on the back of my phone. I don't know why it's not the same.
Thanks for your help

when phones are refurbished, they change the imei number so its probably just a refurbished phone. Leave the imei alone. Im pretty sure the imei doesnt affect the phone recognizing the sim card anyway, but i could be wrong on that

They do change the IMEI when they refurbish, but they also put a brand new sticker on it that shows the new IMEI. Also it's a different sticker than the one that comes on a new phone. It's a different size and it positioned differently. Makes it VERY clear if your phone is new or refurbished.
Aznn0, though you may not realize it what you bought is a stolen/blacklisted/insurance exchange/etc S4. It had a bad IMEI and the seller changed it (illegally) and then sold it to you without bothering to mention the device's history.
If you changed it to the IMEI listed on the back of the phone (And I am telling you in no undercertain terms that you should not!) I'd bet latge sums of money that the phone would go dead because the IMEI listed on the back is a blacklisted number.
So Samsung won't touch it ever again. They will never do a repair for you. If it breaks, you're on your own to fix it.
None of this is probably your fauly and I believe you didn't know what you bought. But it is what it is.
Regardless, asking questions about how to change an IMEI are expressly not permitted on XDA. I know you didn't know, so no hard feelings. But don't ask about how to change an IMEI here again.

yea they do put a new sticker on it, but allot of sellers on ebay/craigslist remove the sticker so that they can sell it as "new" and get a few extra bucks. most sellers assume that buyers wont ever find out which is probably true 90% of the time

Thanks for all your replies.
It's weird because I put in both the IMEI numbers listed from the back of the phone and the one listed in android and they came back clean. I used one of those free esn checker websites. I know they aren't 100% reliable but damn..
I thought matching the IMEI number would do the trick.

It sucks...
I'm having the exact same problem! Mine is an s4 active and when I called my phone service provider they didn't tell me that mine was blacklisted or anything either...

error 119 your mobile phone's imei number not match, plz help me

[Q] IMEI on the sticker is different from System IMEI in F240S

I brought Korean LG G Pro F240S. I noted its IMEI number, written on the sticker on the back of the battery and verify it with System's IMEI (from Phone Information) and found that both are different
IMEI on the Sticker start from 35503xxx
IMEI from System start from 0135200xxx
Please somebody tell me is there something wrong with my mobile, or it is a usual case with others too .. ?????
By the way 0135200xxx is AT&T IMEI number. Where as it is a Korean set.

Did you buy a used phone? If so, it might have been stolen and then the IMEI must have been changed by the thief.

Continue using this one. It's not your fault that you got this changed IMEI but be careful in future. Never buy phones without box and match IMEIs. These phones get blocked with stock IMEI as they are reported to authorities.
Edit: Your phone is 240S. You should use 240S ROMs.
