[Q] how to restore IMEI on galaxy nexus

I got a used galaxy nexus which wasnt factory unlocked but the owner unlocked it. Now i have a generic imei and want to restore it.
Oddly i cant use the.phone on its original carrier but any other one. I think the problem is the generic IMEI but since i got it from some one else, they didnt make a back up of the original imei file so i could restore it. Im really frustrated and will appreciate any help. Thanks

You can find a shop with an SPTBox and the will do it for ya

Hey, i did what you said, indeed its restored. Now my main concern is if flashing custom roms affect the imei number. I dont want to mess up things, thanks

Simply put, Sptbox is hardware + software solution that allows write access to system partitions that aren't accessible otherwise. In this case, the EFS folder

i can not find sptbox toolkit here

Sptbox isn't here, and it's not free either. You have to buy the box and the software that goes with it. If you Google it, it should come up with better results.

someone could told me what are the default generic IMEI used on gnex??? I want to try to make them unavailable in my country if they arent yet.

I have restored mine with na octopus box and uart cable. I had to buy the box with Samsung activation + uart cable.
For me, it was a good deal because I will use the box for many other purposes. Ig you wanto to buy the box just to restore your IMEI, it might be too expensive.
Just Google it and you will know what we are talking about.

[Q] [Help Needed] Service State: Out of Service GT-N7100

Hello guys, I really need help here.
I use a Samsung Galaxy Note 2 GT-N7100, it was working fine until I decided to Root it using the All-in-One Toolkit which also worked fine after Rooting. I later decided to flash a Custom ROM (CM 10.1 - Android 4.2.2) so I did a TWRP Nandroid Backup then flashed the ROM. I was disappointed by the new ROM especially the Camera Quality so i chose to go back to old ROM.
I tried Restoring the backup but it kept failing, so I flashed a stock ROM, re-Rooted the phone and tried the Restore again. When it finally worked and I got the phone running, there was a very big problem: SERVICE STATE: Out of Service & MOBILE NETWORK STATE: Disconnected. I cant make calls, Cant send SMS nor surf the Internet. I really don't know how to go around this, I tried Factory Reset but no Success.
Help Please.

Go to about phone then status post first 4 digits of imei number. I think youve corrupted your efs..

The first 4 digits of the IMEI shown is 0049
Which i have noticed are different from the IMEI shown behind the phone itself.

0049 is a generic imei which means your efs is corrupt.. did you take a efs backup like all the rooting and custom rom guides say to take once rooted.

No, I didnt do and efs backup :crying:
All I remember to have done was the TWRP Nandroid Backup.

Check your sd card for a folder Named EFS. If not you can try flashing stock rom via odin which some people have succesfully revived there phones with.

There are loads of guides on here @Xda For this problem. You can use the search feature and type note 2 lost imei and the guides will pop up.. if your not familiar with odin you can use kies but you will need to purchase triangle away. Then unroot to connect to kies..

I had erased everything from the SD card and Internal storage :crying::crying::crying:
i have also tried the Stock ROM but there is no success.
Isnt there a way maybe that I can get the efs from another phone or download a backup? Or can the phone be revived by any custom ROM out there? :crying::crying:

The only method for you then is to purchase triangle away from play store. You should be able to use wifi. Open triangle away reset flash counter. Then in super su go to full unroot. Then open kies and click tools click firmware initialisation I think it is and enter the model number and serial number of your phone. Get this from under battery. Accept the kies download and wait for reboot. Some people have had success with this but yiu defo need to purchase triangle away to reset your counters. Without reset kies will not work..
Edit: just been looking and apparently once youve installed newer roms you cant revert to anything before dmf firmware. Unless you had your efs backup..

Sorry to tell you that I have this problem 1 week ago, I didn't back up my efs, I tried installing more than 5 official stock roms, and I couldn't retrieve my efs nor my imei number, and finally I gave up trying and sent it to samsung for repair today
Read that if it could help you by any means ...

It should support. Did you use triangleaway and unroot through super su. If kies detects any mods such as root or custom recoveries it will not work.. I have seen loads of people have success with this method while others have had success with odin.. if both havent worked for you, then its gonna be a costly repair at service centre im afraid..

I tried it several times but it fails with the same error. I was also thinking of the Samsung Service Center Option but :crying::crying::crying: I am in Tanzania and all I can find here are Samsung Shops and am told for a service center I need to Travel to Nairobi - Kenya (Nearby country) which is actually going to cost a whole big lot.:crying::crying::crying: so Practically am stuck with the Note 2 that doesn't work.
One final request, can anyone please please please help me with a EFS Backup image (either TWRP or CWM) and the procedure to change the IMEI in the efs image so that I can change it to my original IMEI and then restore it into the phone just to breathe some life into the device. I'd really be thankful for that.

I have tried searching for many solutions, I even downloaded some efs image an d flashed it to the phone using ODIN but as a result it got me a new problem, FACTORY MODE. though i successfully got out of that but I still have the IMEI problem. When I search all I can find is HOW TO BACKUP AND RESTORE EFS and it works only if you had a backup or the Original Shipped efs (all of which I dont have).
Another solution I found out there is to use a Z3X BOX to repair the IMEI but very hard to find out here. so the only option I have left is the one I requested in my previous post. I hope anyone out there can help me

No one is going to give you a copy of there efs.
Youve tried odin it didnt work..
I tried helping you through kies that didnt work. You cant restore something you never had or deleted.
I know this sounds harsh but your gonna have to pay money to get your note running again like so many other people who didn't take the time to read the guides and tutorials before getting flash happy.. I hate to say it but youve learnt the hard way..

Search for "ARIZAPatch" it will help. But it requires root access so you will have to root your phone. I used it on a Note 2 with a similar problem and now it works like a charm.

@Bajanman sorry but that guide is useless for the LTE Note 2 variants. Look for guides from the LTE Note 2 or the North American SGS3 as your main starting points to try and solve this. (My T889V LTE guide has some links to those.)
One method I'd like to hear reports about is the reboot nvrestore one, I've seen it discussed mostly on a Verizon SGS3 thread, but nothing IMHO says it wouldn't be relevant for the HSPA/LTE versions either.
Edit: The EFS and other related partitions are of a significantly different layout between the dual-core SGS3 and the LTE Note 2 or GT-I9305. adb reboot nvrestore doesn't seem to do anything on our devices.
Good luck,
Darkshado

hey i didn't find anything...i've heard that there's some custom roms that contains EFs backup that can solve my problem is this true ? if so can anybody give me a link for one of those roms ? thank you

Try to flash with odin the stock rom that you got your note 2 with. It happened to me once where i flashed something and lost my imei. I didnt backup or anything. After i flashed the stock and unrooted my phone my imei reappeared and my phone worked again. BTW it was a att note 2. I found the rom somewhere at this forum. No rom contain you Efs i think(could be wrong) but each phone has it own imei.

Please Help: IMEI Changed FIXED!

using Galaxy Tab S t705
IMEI has been changed to 004999010640000/01
what I did:
1. I came from CM12.1
2. I flashed lollipop stock Rom
3. I've noticed that even if it has full signal bar, it shows that "emergency calls only"
4. I checked my IMEI and yes it has been changed
how to restore my IMEI
I got not backup of my Working EFS

That's the default imei when the EFS partition is corrupted or wiped. Its not the first time I've heard this happening with cm 12.1
If you didn't make a backup there's not a lot you can do.

i'm doomed

I remember that I got a backup of a ROM with working IMEI, so basically I just Restored it from TWRP and as a result it has my IMEI back again.
