Hey Guys!
Yesterday I bought an LG G3 D855 32/3 from second hand.
It's already running a Custom Rom I don't ask to restore it couse I'll bump the bl right after the buy.
Today I check some thing and I see my IMEI is 0.
But I have a network conenction. Gsm, 2G, 3G and 4G too.
What does this imei 0 means for me?
This is for the custom rom?
Can I backup this efs ?
Can I loss my network If I switch rom?
Regards!
This happened to me on my d851. Unfortunately the IMEI is corrupt, but I was able to recover. After that, I made sure to back up my EFS. If you google "lost imei lg g3" you can find info on the recovery process with a little reading. Anyway I'd make sure you have the original IMEI still under the battery before proceeding. You also might want to check the IMEI to verify it is clean.
Do note, though, methods of writing the IMEI or supporting such are allowed on xda, though.
To answer your question on ROMs. When I had a 0 imei, I was able to connect to providers (att / tmobile) on multiple roms including stock. So in my case, it was just a nagging knowing it was 0. No ill effects. Your experience might be different, though.

I have the same problem with my d851, IMEI shows 0 but i am able to make calls, text, browse,2g,3g(Havent tried LTE yet). How do i get my imei to display.
Its not a problem tho as i am able to connect to network but it will be nice if it displayed.

It's only a problem if you resell. You have two options.
1) Contact LG and tell them what happened was a bad flash and hope they will allow you to send it in to get fixed.
2) Do it yourself, as I did. This cannot be discussed on xda because it could be used to change an IMEI to one not assigned to your phone. I ill say it's possible and using the software required is a legal grey area, but I technically DID sign an NDA with Qualcomm during the time I fixed my phone. Work reasons, so it may not have covered it, but still. Also there seems to be one version of the stock ROM that works with the software. for D851s that is.
Edit: The problem is the EFS got corrupt. If you fix this by all means BACK UP YOUR EFS and store it 100000 places
Very good advice indeed!
Had this problem with my G2 once

But as i have read in the past, replacing your imei with one that doesnt belong to ur device should cause a hardbrick. Also, i dont live in the US, i bought the D851 from a phone market i think it has been refurbished.
THis could mean that the imei at the back of the device might not belong to this device (I dont really know... at least, thats what friend suggested.) I checked IMEI.info for the imei at the back and it turned out with a no results. Then i checked it on the T-Mobile site and T-Mobile said the device has some bills and if the bills are not paid, it wont be able to be used with T-Mo.(I dont really care as we dont have T-Mo here. But atleast T-Mo recognizes the imei.) THen i checked the imei with one more imei database and it showed up.
Now, my problem is that i know of Qualcoms Program that allows the IMEI to get reassigned but i was wondering that was for devices that are not able to connect to network at all. With mine it seems the IMEI is there. Its just that the OS is unable to read it. Dont you u think using the Qualcomm process would be a little harsh?
Also since its able to connect to network, i think my ISP is able to read my IMEI. Could i call them and ask them to tell me my imei? So that i could compare it with what is written at the back of the g3?
EDIT: I just got off the phone and the ISP/Mobile Network agent said they are unable to see IMEIs from their end.(Not just mine but everyones). I dont know, maybe she just might not know how its done. I will still keep trying tho.
Restoring using Qualcomm software IS hard, overkill and VERY RISKY. At the moment since your provider doesn't care, I say ignore it. Also I have no idea what would happen if you tried to change an IMEI to one not meant for your device as I've not ever attempted such. You phone sounds like it has a bad IMEI, but that would only as you said blacklist it on TMO. The IMEI afaik is only used to track stolen phones and deadbeats on bills. So as the saying goes "If it ain't broke don't fix it". If I were you, I would question the person you got it from about the bill delinquency, but you don't really have to. Just seems fishy to me.

Hy guys,
I have a situation and need some advices
I have the opportunity to buy NOTE2 for a very fair price, BUT device cant read a sim card :-S (with sim card inserted)
Device does not have a waranty (because it is bought out of my country, to be specific it is from austria), and seller said he is not take it to a service center. so there is no diagnosis what is wrong with it.
I have not seen the device yet, but i will see it in about two days. Seller said that the device is almost new, and it is fully functional except the sim card.
I was ask him is maybe sim slot is broken (people cut regular sim card, and stuff), he said no (he also not sure, because he exchanged it for something else etc).
But nevermind, I will see if it is hardware problem (lets say that I am experienced in this ). I would like to see broken sim card slot, because it is replacable . But lets get to the part where I need advices. possible software problems
I read through forum, and there is various problems and solutions, and also there are few with no solution
I need help with my check list:
1: I will check the IMEI. If there is no one, I will give up
2: If there is IMEI, lets say that there is a chance (maybe someone flash a different rom etc). My qouestion is: Will I be able to make a proper backup of EFS? ,Then try to flash different, modem, kernel, rescue rom, etc... Without a chance to loose IMEI? (properly getting back with efs backup)
3: I read that there are few guys who bought a retail version of the note (the one without radio chip at all). Is there a way to recognize such? (i dont remmember if this version have imei, or not)
4: Is there a chance that device is only locked. What message appear in that situation (no sim, wrong sim, type unlock code or something similar ?)
5: What are the chances that maybe the radio chip is blown , If we assume that the device is relatively new and not dissasembled or something (I know that this is hard to recognize, but maybe, some services code or something)
6: Is there a some kind of service mode to check if the radio chip is functional
So to conclude: If you guys can help me with the check list, feel free to add tips.
I am sorry for this long post.
Thanks in advance
wow, posted a question last nigh, and now it is on a third page lol
lets bump
So once again, my main question is: Is there some service code/mode to check whether the radio chip is functional/or whether is the radio chip existing in a device?
the rest I will leave to chance
again, thanks in advance
Go to a your local telephony service provider, give them the phone's IMEI and inquire about it if it has been black listed. If your device's IMEI has been blacklisted IDK if there's a tool to clone/change it to a newer one. Once the device's IMEI has been blocked, that process is irrevocable unless the previous owner clears the issue for you.
Blocking IMEI happens usually to phones with unsettled payments for the phone unit.

Thank you, that is sound intersting, and when I've thought about it can be possible cause.
This device came from Austiria to my country, so If we assume that the IMEI is black listed; Whether this can be checked by any carier/service provider? or just one where phone is bought?
thanks again
if it is carrier locked then you should still able to dial emergency number isn't?
in hardware issue you can't.

Just like what dr.ketan said(which is the easiest way to troubleshoot it), try dialing the emergency number wait for the ring(a single ring, then put it down - don't try to call again if it does ring) and if someone answers your call - say the matter has been solved. The phone is network locked.
Thanks guys, I was reading a lot through forum, and my head is full of ...:laugh: so I overlooked the logical solution
Thanks again, will try check phone maybe tomorow, and I will let you know
Hi,
I've bought a samsung galaxy S3 Red version on kijiji (Canada) and realized that the IMEI of the software is different from the IMEI on the back of the phone.
I've checked the IMEI blacklist to see if any of those IMEI is blacklisted, but seems like both are fine.
I've tried using EFS Pro method without a luck.
I also tried doing NVreader-Writer to change it manually with no luck.
I was wondering if one of you guys can give me some help regards to this.
Let me know guys.
Thanks alot in advance!
Personally, i dont think you should be doing anything to the IMEI at this point. Obviously someone changed something along the way. Since both IMEI's appear to be good, theres a good chance someone replaced the motherboard at some point. If this is the case, write the IMEI down! TWICE! Keep it safe where you will not lose it.
If it was a motherboard replacement, DO NOT try to change or otherwise mess with the IMEI! Replacing it with anything but what belongs to that board is asking for problems.
If the mobo is original and the IMEI was changed for some reason, it might be a good idea to change back....maybe! But this doesnt make any sense if the original is still good. If you do somehow verify it was changed, i would wait before doing anything. Someone could wait another month or two and report it lost or stolen. It happens all the time! And then the IMEI would get blacklisted.
I think you should contact the seller and find out what is really going on. But regardless of the answers you may or may not get, do not change anything yet.
If its working fine right now, just leave it as it is. Messing with the NV Data is not to be taken lightly. Its not simple stuff like flashing roms. Make a mistake and it could cause irreparable harm to the device.

Oh, and there are several blacklists out there. Just because it isnt on one, doesnt mean it cant be on another. Check on swappa, but definately call the carrier the device originally came from. Ask if it is able to be activated on any network including theirs.
Hey, Thank you for your reply!
I just wanted to add in some story.
I've bought this about 1.5 months ago, and IMEI of the phone is fine(*) according to swappa, imei.info, and protectyourdata.ca.
Also, The software IMEI of the phone (according to imei.info) belongs to a samsung WAVE II and the original IMEI on the back of the phone belongs to the samsung galaxy s3.
I've contacted the seller when I first got it, this guy was fishy as ever and sounded like he was making sh1t up.
P.S swappa IMEI check came clean and my carrier does not support the IMEI.
What do you mean they dont support the imei? If its an I747, youd have to ask ATT about it.
The thing that bugs me is why would they have changed the imei in the first place if the original was still good? Makes me very suspicious tbh. I wouldnt try changing it for a while, if ever. As i said before, they could be planning to wait a few weeks and then report it lost or stolen.

No idea as why the seller would do so, but IMEI of the phone, Samsung galaxy wave II does not work with the Virginmobile Canada that I'm currently using. Should I get it fixed by a people who changes IMEI of the phone?
Just to be on the sure side, how do i check if the phone (sgs3 i747M) is carrier unlocked?
Thanks DocHoliday!
If its locked it will ask for an unlock code when you put a different carriers SIM in. I don't know how the different imei would affect this though because any unlock codes would be created using the imei.
I can try to help you change it back to the original if you like. But I make no guarantees. If it ends up being blacklisted you'll be out of luck. Changing from the original imei is called cloning and 99% of the time is highly illegal. It is the reason it is so hard to find out how to do and why we are not allowed to discuss it in public forums. Its also one reason why I will be unable to help you change it back. Also, The software and the device will reject the change unless done with special equipment I'm told.
So if you decide you still want to go through with that, you can PM me. Itll at least save you a lot of money for this part. Please include the details and a link to this thread so I don't have to come back and search for it again though. I fix tons of lost imei problems and it can get confusing without having the background included in the PM.
To make a long story short, I bought a T-Mobile unlocked Note 3 off of Swappa, and after three tries I finally got one that didn't have mismatching IMEI numbers, or one that got blacklisted like 5 days after I activated it. Anyway. This newest one was activated and fine until I got home and I did the OTA updates. Now it is saying that my "IMEI Cert: FAIL, -4" when I hit the *#0011# code; resulting in my loss of service. I have been looking all over the internet for a fix for this, and I can't find anything except for other people with this issue, and websites with poor English saying to pay them to fix it. Does anyone have any real info?
A quick Google suggests that using Odin to flash a stock ROM might fix it. I would do a full factory reset first as well. Get things back to base stock, as much as possible.
I seem to recall that some issues with EFS backup/restore in custom recoveries early on were fixed by wiping the EFS partition and rebooting. Apparently the modem firmware has a way to rebuild it on N3. For details, search the general forum and/or development forum. I don't recall details, just some talk about it working as a way to fix devices that got messed up. Don't even ask here about changing IMEI or other illegal options. They are not allowed on XDA, if they are even possible.
I can't believe you went through 3 bad phones. One would have been enough for me. I simply don't buy used phones online anymore. It's not worth the bother to me. I buy direct from TMO as I can make them fix it if they give me a bad one. Sucks, but since they can blacklist any time, and leave you hanging, I want to be sure I have a reputable place to go to get it replaced if that happens. I hope you get yours working again.

This may be a little bit late, but I just discovered that I could fix mine with the exact same issue by flashing a Jelly Bean modem for my model.
Under any firmware on KK or LP, it would Certi: Fail, as soon as I flashed a JB modem, it worked again and passed.
Hi,I have this issue with my T-Mobile Galaxy S3 (SGHT999)
.It seems to be in the Edge network even though I'm in a 3g/4LTE service area. The phone is slow.I could use a solution and looking for suggestions on how to fix this 4G network phone.I have another Galaxy S3 (SPH-L710) with another carrier with no problems. Well one problem I'm not with that carrier any longer. This phone doesn't have a sim card slot like the T-Moble phone has. The other problem is the wifi reception. Its ok in the room with the router but you go say 30' away and communication is spotty. Other S3 phone I could be 100' away no problem. I thought all Galaxy S3's were the same. Thanx for any help.
What carrier are you using it with? Make sure you have correct apn settings. For the WiFi not sure, 100 foot seems a little extreme for no problems, unless they were different routers
Sorry to resurrect an old thread but Im facing this exact same problem right now. I have two SGH-T999s, both unlocked, and while 4G works perfectly on one, the other only works in GSM/EDGE mode and will find no signal when I switch to WCDMA only. Both phones in the same location, the exact same sim switched between both handsets, works fine on one and not on the other. I have already reset the phone multiple times, reflashed the stock firmware, replaced the stock firmware with CyanogenMod 11 as well as the 12.1 nightly, NOTHING makes a difference. It will stick to GSM and EDGE only and will just not connect in 3G/4G.
At this point, I am guessing this is a hardware problem. The same exact stock firmware has been flashed on both devices, so it cannot be a difference in version. The phone with the trouble has been dropped and has a shattered front glass. I wonder if something else might have been knocked loose when it fell. I opened it up and tried to reconnect the antenna, but noticed that only one end was using a connector, the other end appears to be soldered. I did not try to pull the motherboard out, nor touched the sim tray.
Does anybody have any suggestions on where to look next to troubleshoot this problem?
I am also having this same problem; I've tried everything, including the things on this thread: http://forum.cyanogenmod.org/topic/...ge-on-phone-and-not-34g-imeidata-issue-fixed/
If anyone has found a solution, that would be great...
Check to make sure the imei in About Device isn't blacklisted and that it matches the one under the battery.
If it does and you have Odin flashed the stock firmware and factory reset, it is most likely a hardware problem.
FYI, the antenna you see when you open it up is the wifi antenna, not the cellular one.

Hmm, I saw that there was an IMEI present, but never considered it could be different!!! You are right, the IMEI on the back of the phone does not match the one shown in About Device! How could this have happened? The person who used it before is not someone who fiddles with their phone... The best I can think of is that whoever unlocked the phone for them must have done this!
I did see numerous threads about missing IMEI, but didn't pay attention because mine was not MISSING it! Also noticed it is against xda site rules to even discuss that stuff. But since I inherited a phone that came like this, I guess the mods will forgive me for saying "let me google this"
EDIT: Oh yes, the IMEI on the back of the phone checks out.
Also, did not know the antenna was the wifi one! But since its IMEI related, I guess thats not an issue anymore
Fixed it!!!
UPDATE: As per DocHoliday77's advice, I'm deleting the links and explicit instructions. Suffice it to say all the information you need to do this is available on this site itself.
After @DocHoliday77 pointed out that the IMEI may be incorrect, I did some research and managed to restore my IMEI as well as get 4G back.
I was able to restore my device because I had the advantage of having a fully working device with me from which I could pull the EFS partition as well as get an NV dump. For those that do not have a second device, I do not know how they can get things working again. In anycase, all of the information I needed to accomplish this was found in three threads on this site. The only additional piece of information that T-Mobile users need is that to get your device into Diagnostic mode, the dialer code is *#0808#.
Wanam's Partitions Backup & Restore... does a much better job at backing up the correct partitions for EFS.
EFS Professional for everything else.
And before anybody asks, sorry I cannot provide you a copy of my EFS backups. Only becuase I am not knowledgable enough to know how much personal information is contained in that partition, but given that the IMEI is dependent on it, I hope you can understand why I cannot share mine. Perhaps DocHoliday77 will be able to suggest a way for others to get this sorted out.
That's great that you got it fixed! And kudos for figuring it out on your own!
Though you may want to edit out any instructions and links as they are not allowed to be posted. (Too many people jump on this stuff in an attempt to get stolen devices to work again....highly illegal) (it's why this stuff is so hard to find usually!)
If anyone does have problems with this please feel free to PM me and I will do my best to help.

I purchased this phone unknowingly that it was a demo version.
I removed the demo version from it via the code, reset and then flash and update.
The dual imei numbers are both 0000 when I typed some code ( cant remember it showed that the imei is ok)
I wanted to get it repair via some of those remote box services. I dealt with very rude unpleasant person who was impolite, told me to install quite old xsg rom which is different csc compared to my original rom. When I flashed under imei there is UAE csc and new lines added under: TRA ID :
and TA : , and these two were not there before, device also shows just as a52 instead as a52s as previously. The person suggested the rom based on the build number that I sent him.
Afterwards he was asking for pictures and then blocked me.
Im wondering If I can fix this unit to usable cellular state with working real imeis
I thought xposed modules would help, but it seems they only help with apps and only change imei on them.
I highly doubt that this device has banned imei.
I would be happy to help you to root it and I would appreciate if someone can help me.
I searched many threads without success, I know the efs/qcb is probably corrupted
What route I should go to fix this device?
If it is a demo version and has no IMEI this tells you that this legally is no mobile device that is approved to use with operators. Inserting a new IMEI can not be legal in normal countries. IMEI is a device identifier sent with all phone traffic to ensure that the device is a legitimate one and is not stolen and black (do not work at all) or grey (works but flagged to be traced) listed.
Go back to the seller and demand your money back!
I hoped that someone with more experience with this would chime in, on these new galaxy devices the imeis still seems to suppose to be there, in galaxy 8 or older galaxy version there was no 4g module and antenna removed, I think this is what you are talking about right ? and it was purchased on ad.
Im wondering if these services like chimera can fix it.
I thought it's unrootable. How did you do it?

You must be joking; demo phones have no imei. They are not phones they are dummies. Throwing around inane accusations will do you no god around here.
