I have a big problem.
My Gnex i9250 lost your IMEI.
I have already taken the unit on technical assistance and said they would try to rewrite the IMEI but failed.
In my research I learned I should have done a backup of file containing the IMEI (nv_data.bin), is it correct ?
I don't have any backup.
Please help me friends.
NOTE: Sorry for my terrible english.
Not to assume, but it would appear at first glance that you purchased a stolen phone....
Also, pretty sure anything related to writing or creating IMEI is against XDA rules.
Is this a new or used phone? Do you not have the original box with your IMEI on it? And inside the battery compartment as well?

I live in Brazil but I bought this phone in NY.
It's a new phone and the IMEI number on the box matched the number in the battery compartment.
I bought the phone in december but I only had problems recently.
I traveled to a place where I couldn't get any signal and I turned off the phone.
After one day I turned it on and it stopped working.

Did you buy it new or used?
There could be a chance perhaps it was a stolen unit maybe from a store or such that when it was discovered gone, the IMEI was disabled.
I just don't see otherwise how the IMEI could just stop being valid.

I bought this phone brand new.
I saw that in some cases the IMEI can be corrupted, but I don't know how can i repair this file.
This its a known issue.. The efs folder gets corrupted.. Go to galaxy s2 forum and try the several fixes for it there.. If your lucky it will work..
If not.. Well there's not a fix for it yet on Nexus.. Theres several ppl around here waiting for this solution.. As currently they just have a really nice music players Hehe..
Cheers

Its not the efs folder like it was on the nexus s etc.
Your imei data is stored in the factory folder on the gnex.
Sounds like it got corrupted.
I lost my imei on my nexus s and ended up being stuck with a generic one, it still worked though.
Maybe you can find a way to do that.

How do you change your IMEI on your Nexus S ?
The IMEI can be changed/repaired on this phone using samsung pro tools. In Brazil it is legal to change the IMEI to whatever you like, in UK it is only legal to repair the IMEI to the original IMEI. There are some IMEI Nazis on xda that don't want to empower users with the ability to change the IMEI, so they won't tell you how to do this, even if it is for the legal reason of repair only. And, will probably get xda to delete this post and/or close the thread, like they are uk police shills or paid subverts or maybe just do-gooders (the latter is the worst).
This page describes repairing the IMEI of the Galaxy Nexus that had generic IMEI (which can be caused by corrupt MD5 hash for nv_data.bin) using SPT box
An SPT Box cost about $200, but you can usually find this service on ebay or google for about $30, they will resotre the imei to the sticker under the battery. You must pay shipping to and from as well. This place might offer such service: http://www.fonefunshop.co.uk.
I had my IMEI disappear, the "about phone' just had "unknown" for my IMEI. My Nexus GSM was only a week old and purchased from the Play Store. The only reason I checked is because I was on the phone with Google Wallet support and they needed to know. Surprisingly, I was on the phone on T-Mobile network, but with an "unknown" IMEI.
I did a battery pull to reset the phone and it was back. The number on the screen matched the inside, the number on the box, and the number on my receipt. I called support back (again, on the same phone) and they fixed the problem once I gave them my IMEI.
I was a little freaked out that it disappeared like that, but at least the battery pull fixed it.
Good luck with yours.

Hey, even i bought from playstore and i have this same issue. Can you tell me how your issue was fixed ? i realize that the imei is printed on the phone just beneath the battery. But how does it reset the phone ?
Ok soo first of all this is common problem for samsung smartphones - and it has nothing to do with stolen phone. I have the same issue as well - IMEI just got lost one day. Getting factory resets or flashing orginal stock from google page dosn't work.
I just hope that it's not a hardware issue - still waiting for solution for nexus. It's crap cause i bought from google play store while being in US - now when i got back to EU it stopped working - sending it back is very costfull...
So only because it's never happend to you don't say it must have been stolen or something!

Unfortunately no, but you can try.
I have the worst luck, my GNex lost its iMEI and II tried to recover it for 6 months.
Then, one day I got the IMEI back (did a backup of the nv data files and deleted them from the system folder)
So look at this: I did a backup on the nv_data files and put it in the Internal Storage
Then, I wanted to revert back to full stock (no root, locked bootloader)
So I flashed the stock (ps: this wiped the internal storage, so I lost the backup files).
When the cellphone booted I didn't have the IMEI again, so I rooted my phone and deleted the NV Data files FOREVER.
So basically there is NO way to recover the files, I lost my IMEI forever.
But for anyone who is having this issue, backup the files (save it in your computer :silly: ) and delete the nv data files from the system. Try everything related to that. (but be sure to have a backup, hahaha :silly: )
Hi guys,
after two days of unsuccessful trying I really need your help now. I was owner of a HD2 Leo and am used to flashing roms and stuff, so I'm not a total noob - anyway:
I bought a Galaxy Nexus on eBay. The seller wrote that the phone itself work, but there it's only on airplane mode. I bought it and thought with flashing it would be fine.
The problem is:
Baseband-Version: unkown
Network: unkown
IMEI: unkown
I am not been asked for a PIN when turning on the device. No network connection is available.
In two days I tried:
- Galaxy Nexus Toolkit > flashing Google Stock 4.0.1, 4.0.4 and 4.1.1
- Flashing several Radios including i.E. UGLC1 via Fastboot
- This thing here: [TOOLS] Unbrick dead Samsung GT-i9250 Galaxy Nexus 32GB / Prime via USB cable http://forum.xda-developers.com/showthread.php?t=1640443&page=1
I actually don't know how to continue and from todays view I bought an expensive MP3-Player for 250 bucks.
I would really appreciate if you guys could help me out.
Thanks in advice.
- Sebastian
Uh, EFS partition is borked.
Look at this thread, maybe the restoring IMEI part is relevant.
Pew ... this loos tricky. I'll try that.

It could be related, it's either broken hardware or corrupted /factory folder.
The files in the /factory folder holds your IMEI, it's proven beyond doubt.

Galaxy Nexus baseband issue
Hi, I have the same issue.
The phone was working fine and it just stopped working. So I flashed the factory images once again but no luck.
Then I suspected EFS partition issue but after rooting, I could list the files under /factory, cat/read the md5 files, copy them etc. So I think EFS is not the issue but don't know what has gone bad.
Still my phone is not working
Found this, dunno if it'll help, though...

Fixed by sending in for warranty
Just an update...I was having all of these symptoms...unknown IMEI, Baseband, etc...basically gave me an expensive media player for a few months while waiting for a fix on XDA. After no update I decided to call up Samsung and after talking to 3 different technicians, I was able to send it in. Just a note for anyone about to do the same, they will try very hard to blame it on the carrier/SIM card, so save yourself some trouble and just say you already went to the physical store of your carrier (calling isn't enough)and they couldn't get it working. Once you get past that, they will email you a printable 2-day UPS shipping label so you can ship it to them for free. It took 2 weeks from the time I called to having a working phone back in my hands.
This was their fix:
Problem found:
NO PCS SERVICE
Solution:
REPLACED PBA
After a quick search I found that the PBA is the motherboard, so it's definitely a hardware issue. Hope you guys are still under warranty because I've heard this is ~$200 to fix otherwise.
Good luck.
I recently changed networks, its was only then that I discovered that at some point in the last 2 years my IMEI had reset to the default, most likely due to me deleting something I shouldn't have.
I know its a log shot but does anyone have a back up of the following directorys?:
/efs
/factory
/data/radio
these are what are missing from my phone, I believe that the /efs is the most important in getting my phone back to normal.
Thank you

Using someone else's backup of the nv_data files will give you their IMEI number. Not sure anyone is willing to do that unless they have a Gnex just collecting dust and they don't care.
I'm considering this option: http://www.sammobile.com/forum/showthread.php?t=7554
With the cost of the special USB cable and software totaling about $40, you get one shot at repairing your IMEI. I haven't tried it yet....

I am also very tempted by that but I have just been bitten by one such SRS service that could not deliver what they promised (efs fix) and am now having a paypal dispute with them. Who know how long it will take for the cable to turn up and I am getting a new phone next month
So just got back my M8 from HTC after a repair, was having problems with calls and I called HTC UK to find out what was replaced or done to my phone but they wont tell me, anyone had any experience of this, as i find it quite shocking they wont tell you.
P.S i sent with S-Off, and now its S-On, so i guess they replaced the board, but would like to know for sure.
Do you know if is indeed the same phone. If so then they probably just reflashed the current stock firmware. I doubt they would replace the board for that because if they change the board and still have issues they wasted time and money. If it isn't the same phone then they replaced it. Check your imei and serial number. Call your service provider and have them look at your phone and they can tell you the numbers they have.

thanks for your reply, but reflashing wouldnt have fixed my problem, as i had the problem, on stock, on GRe and then back to stock. I think it is the same phone, as there was a very very small notch on the right side of the phone, and its still there. also when i spoke to them, they said it was in testing, then went back to repair. I would assume that new board was the only fix for my problem, as i cant see new speakers fixing it, and it was not software.
Hi All,
Just found that after the phone appeared to be overheating substantially, my H818N just died and wouldn't restart.
Tried everything, but nothing worked.
Took it to the local LG workshop here in Mumbai, India - where the tech pronounced the motherboard dead and that it would be impossible to recover the data.
Further, they would not give me back my motherboard (with chip/ROM), unless I paid them the full price in cash for it.
I paid up in order to secure my personal data, and researched solutions.
Apparently someone in Russia says it would be possible to recover the image.
Any feedback on this and possibilities - as I would have to spend a bomb on shipping it out with the restrictions implemented here in India? (I could mail it from a European location if I fly out on a trip, but have nothing planned)
Thanks all!

How much did you pay and what were you paying for ?
no warranty on your device ?
No personal data on your sd card. What was left on your main storage to pay anything for.

There was warranty on the phone - it was only 9-10 months old.
They replaced the motherboard for free.
As stated, they would not return the old motherboard if they were replacing it under warranty - as it would have to be returned into their system for inventory purposes, apparently.
And that is why I had to pay LG India INR 24,000/- = USD 363.64 to keep my old one.

When you said you tried everything, to recover it what did you do ?
How many days did you try before giving it in.
If you had a second chance what you have done differently regarding data storage so as not to end up in this situation.

Seems device is out of warranty . And yes there are solutions to recover the data but they are pretty hectic to perform. You can remove eMMC from the device and mount it another device which should be compatible with eMMC . And you are good to go. 2-3 days ago XDA published a article and told us that a guy successfully implemented 64 GB eMMC on his 16 GB nexus 5. the process is real hard and need particular skills . But if your data is that precious then you can try. And yes always backup your data ..always

In the days when root was possible you could image the entire storage. Without root you can't do that.
App data stays in app folders some backup programs will take them others wont.
So the ext microsd card is the place to store downloads and everything camera related. From there you can back up locally or to the cloud.
Am really surprised this had happened to you as i always champion expandable storage for just this sort of eventuality against non expandable storage phones
There is another question to be asked here. Would you say your device went into a bootloop.
Were there any signs of flaky behaviour before this.
usually if a phone is getting hot best to shut it off and try after. it seems it got hot enough to affect some solder connections inside. The weather is quite hot these days so operating for long periods under elevated temperatures isn't a good idea.

Also, whether this would even work with the new motherboard? What about hardware IDs/linking to the previous software/system/OS?
