IMEI Messed up, help please!

I was told to post here so:
Hi,
Yesterday I flashed a custom ROM , the rom somehow messed up my IMEI number.
Then i went back to the forum and found out that everyone who flashed the rom got his IMEI messed up and we all got the same IMEI now, i still have calls working but im afraid they will stop working soon, i know what was my original IMEI, can anyone help us please. (Heres the rom i flashed: http://forum.xda-developers.com/showthread.php?t=1034130)
I saw that the devs on samsung captivate managed to restore their imeis, there should be a way to do that to the nexus s.

Same Problem with my phone...

same here
I'm restore my backup .. and nothing change
and imei still changed :S

Same here, i think the phone is as good as network dead.

Hi all, I also was unfortunate to flash this rom resulting in the changed imei issue. My Phone was displaying emergency calls only and i was unable to connect to data services. I used Odin to flash back to stock GRH 78 ticking the phone efs clear box . After rebooting i checked my imei number but it still displays the wrong number. However my phone now connects to the network and i can make and recieve calls and data is enabled. Not a full fix and i am not sure for how long it will work but definately an improvement on the very expensive paperweight i had. Hopefully a full fix will come soon.

Trying that~!
UPDATE :
Nope Odin again didn't help.

Isn't it kinda stupid to discuss this in not only one or two but four threads? I get it, you guys want a fix and I feel with you, but having four threads will only cause confusion.
How about you all agree on one and work together to fix it instead of dividing your efforts?

Can you explain what version of Odin you used - Odin3 v1.8 ??
What rom did you flash stock GRH78 ??
Did you use a .pit file and if yes which one ??
What boxes were ticked and de-ticked in Odin ??
Cheers mate

Hi,
I used odin 3v1.8 and the stock GRH 78 rom. I opened odin and loaded the
bootloader, Pda and scs files and ticked the phone efs clear box ,this was the only box i manually ticked all other boxes were left in their default state. i did not have a pit. file. Previous to using odin I had just unlocked my bootloader as it was locked. Odin won't work with bootloader locked all atempts to access download mode were met with a unlock bootloader screen.
After flashing I checked my emei no. but was disappointed to find no change. I then checked for system updates and clicked on the update which started to download. It then suddenly dawned on me that i had not linked my phone to my router and that data was enabled. I cancelled the Gingerbread update and went into notifications and saw my network instead of the previous Emergency Calls Only. A quick phone call verified that my phone was now connecting to the network. I then connected to wifi and installed the update.
I am still stuck with the wrong emei but can now connect to the network and
have restored my favourite rom from a nandroid. The only issue i now have is the
wrong emei but for now my phone functions perfectly

Probably something messed with your /efs partition.

Why did you have to do that? I don't assume you have a backup of /efs, do you?

I wonder how long it'll work ...
Y'all could try to look in the forums of the various Samsung Galaxy S variants, AFAIK there are ways to restore your IMEI on this kind of Samsung phone, maybe they apply to the Nexus S as well.

[Q] Recovering/Replacing the IMEI number

So I just received a replacement phone via warranty from T-Mobile.
I have upgraded to Gingerbread 2.3.6 and am rooted.
I just realized now that the IMEI number in Android is 00000000.
I'm not sure if it was like this before I started tinkering with it or if it happen as a result of the root/upgrade.
Anyways, I have the sticker that gives me the IMEI number under the battery, I just need to know if/how I can get this back into my phone. I've read something involving a HEX editor? But I don't know what or how.
Any advice and links would be greatly appreciated.

A little more information. I originally noticed that the IMEI was set at 0000000 because I tried to install Swype beta and it says cannot install on an android emulator. Further googling of this lead me to realize that swype wasn't recognizing my phone as a legit android OS because the IMEI number was missing...so yea. This is where I am now.

Did you make any backups before upgrading to Gingerbread 2.3.6?
ADD: Here is a quote off another thread with this problem:
I got my IMEI back. I had my nv_data.bin.md5 and nv_data.bin backed up when I unlocked my phone after I got the new one from Samsung. I just coppied them the the efs folder and my IMEI is back."
Hope it helps! And hope you have a back up... maybe even from your other phone?? Or before you upgraded the phone you have.

Should they be in this directory?:
/efs/root/afs/settings
because those are the only ones i can find

Yes.

So I have the nv_data.bin and nv_data.bin.md5 files from my old phone and from my new phone. Sorry, I wasn't thinking enough to make a backup of these files when I upgraded to Gingerbread using Samsung Kies.
So now, with these two sets of files. Do I want to take the old (and good) files from my old phone and replace the files on my new phone. Won't that transfer the old phone's IMEI though?

First - Is your phone working?
Second - Have you tried a factory reset if your phone is working?
Third - Try a factory reset and reflash a stock rom.
Fourth - If you phone is not working give it a shot and let us know

Yes the phone is working fine. Just with the IMEI missing, I can't get Swype beta to install (I'm assuming that is the problem)(That the only problem I've found so far). Would a factory reset restore the bin files and IMEI number then?

What I have read is a factory reset or reflashing a ROM (or both if all else fails) should restore your IMEI. I have also read flashing the original ROM that came on the phone has worked. You may try that if the factory reset does not restore it.
Since your phone is working don't copy the files over from your other phone
Do let us know your progress.

How do I obtain the original rom, is it posted here in the forum?

I'm hitting the same very disgruntling problem that I did in the past when I tried to use CWM. When I try apply update from sdcard and I choose my update.zip file I just get E:signature verification failed and I can't proceed from there....

You need a custom kernal to flash from CWM. That is why you are getting that error. Let me look for an odin flash back to froyo stock for you.
On a side note - I have read taking your battery out for 10 mins has worked for some. Since your phone is working you may try that while we continue to look for a fix.

Sucks that this kind of problem would happen from following these instructions. I figure it would all automated and such...

and my battery is out now.

I say before going back to froyo try raver's ROM-ODIN-2.3.6-Gingerbread Offical Maybe a stock reflash will work. I have read a thousand ways that have work for different people now. You have done a few. Try this as it is easier than going back to froyo for now. Let your battery charge first.
Maybe kies just f-ed up your imei. And where are the big dog's when you need them? bhundven/FBis251?
Did you just root? Or did you use an app to unlock your phone as well?

For those who have no baseband and null Imei on their i997...

Im not sure were to put this so called tutorial so mods feel free to move it to were it belongs if its not supposed to be here. I was having a big issue with my Samsung i997 thats was showing no baseband on settings, No imei null/null and of course didnt have any signal. I started a couple threads about things related to that. No luck, until a member called Truckerglenn pointed me to a efs .tar file he had made that fixed his phone.
So before i start, credit for the efs file goes to Truckerglenn i had nothing to do with that. Then, i want to make this clear, This worked on my i997, it doesnt mean it could work on other phones but for some reason i think it will. I messed up mine on purpose a couple times after i solve it just to see if it was a real solution or just luck. It worked every single time like a charm. With that said, i got to make clear i didnt have a copy of my original efs file. I have deleted the efs file a couple times also. So i think none of you could mess a phone worst than i did, and i still managed to bring it back to life using this method.... So lets talk about what i did:
First download Truckerglenns efs .tar file located here:
http://forum.xda-developers.com/showthread.php?t=1438113
In my case i used the infuse unbrick ODIN file so i dont know if it works with any other firmware or not.
Open the ODIN file located on the infuse unbrick files and click efs clear, yes i know it sounds very risky and people have made clear that is not recommended but hey, you cant mess up your phone worst than you already have so. Anyways, put the infuse ODIN files were they belong, pit, pda and phone. Then here comes the tricky part, i used the Truckerglenn file in the csc box to flash it with the unbrick files.
Click start and the phone will flash the stock Froyo for the i997, wait until the flashing ends. Then when the phone reboots into recovery before hitting reboot go to wipe data/factory reset and click it. Then you can hit reboot phone and if youre lucky enough you will have your signal, restored imei number and baseband version.
Like i said this worked for me and i cant asure you it will work for you. But after all those weeks i spent dealing with this without success and having deleted efs many times and messing the phone that much, i didnt have anything to lose. Also thank Truckerglenn for his efs if this work on your phone, after all im just giving you an idea on how i made it work on mine but i didnt create a file or anything i just flashed it the way i just told you. Good luck guys and keep up the good work!

this happens to me as well, but flashing an efs didn't help me. any other ideas?

Step by step??

So, I am having same problem as u were. One thing that I want to make sure is do i clear efs and then flash ?? or just click the box on the efs clear and put everything and flash it??
So here is first option - You check on the clear efs box and then click "start". After it's finished, put other files and click "start" button again.
Here is second option - You check on the clear efs box then put all files and click "start" button and done.
which one is correct way to do this process??

It's been a while now, but if I remember the Clear EFS box was checked, so go with option 2.
But hey, right now your phone is 'FUBAR'. Try different settings if one doesn't work, maybe another one will.:good:

Thanks Truckerglenn - you saved my phone:good:

Ok, my phone got fixed by AT&T. But it wasn't software problem. My radio chipset was burnt. I checked and when AT&T saw that, they just replaced my phone to new one. For free. Pretty happy now. Thanks for help tho

Thanks!
OMFG...I bricked my Infuse a while back and I thought all hope was lost. I have bought a Note since then but I wanted to sell it and wait for the Note2 while I could still get a pretty penny for it.
This worked like a champ.
I basically followed your instructions using the Unbrick package here:
http://forum.xda-developers.com/showthread.php?p=27286083#post27286083
I also checked the EFS clear checkbox. I didn't have to factory reset from recovery either. It just rebooted and I popped in my SIM and it worked!

So I haven't gotten to the stage where I do not have signal... but do plan on moving my infuse from 4.0.4 to 4.1.1. Through this process, it has been noted that you could lose efs. So before I tried to install the rom, I backed up my efs through root explorer. Within this app, all I did was copy my whole efs file and pasted it to my SD card. After this, should my efs be fully backed up? And if I were to install jb and WERE to lose signal, how would I go about restoring it? My efs is on my internal storage..

@TokyoLee
It would be best if you informed us of the upgrade path you took.
Slim ROMs (I am assuming you are trying to flash a JB 4.2.2) are known to cause loss of IMEI if flashed directly from ICS. Best solution would be to flash a CM10 and then a CM10.1 before flashing SlimBean. I have followed this path and have had no problems although I have gone on to Rootbox 4.2.2.
scott.hart.bti's Unofficial CM10.1 post has instructions for the proper upgrade path, see here: http://forum.xda-developers.com/showpost.php?p=28842232&postcount=1
andros11's "[Guide] How to Flash Jellybean" here: http://forum.xda-developers.com/showthread.php?t=1878458
is an essential and important read to avoid any IMEI snafus.
Also, and this important since almost every JB ROM thread mentions it at one point or another: REMOVE your external micro-SD card from the device before flashing a JB ROM.
Hope this helps.

You may have to start fresh from GB [or Froyo]. That would be the best recommendation.
qkster's posts are valuable in how to get back to GB. See here: http://forum.xda-developers.com/showthread.php?t=1524081

Unless you have your EFS backed up which you can flash via ODIN or Heimdall it is impossible to get tour IMEI back.
Best is to go all the way back to GB.

Do not even think about doing such a silly thing. This is an Infuse specific efs. You cannot flash it to the I-9000 or I-9100, for example. The partitions are different on different Samsung phones, they are not necessarily interchangeable.
Unless there are clear instructions available, you could end up with a very expensive brick.

Hello, I had sent you a message to try and help as much as I could but you opened a thread so I'll help you on here.
First. Double check all twrp folders using a file Explorer. Some roms when flashed through twrp automatically back up your efs partition.
Second. If the folders are blank then we'll proceed to try other methods of fixing your imei.
I assume since you went from having a blank imei to that weird number you tried one of the methods you found through Google.
There are ways to manually reenter your imei if the methods found on Google fail. Follow the instruction in the site below (I highly suggest using the terminal emulator method) and report back here. Your imei can be found on your Sim card or the bigger card your Sim came in.

This right here.
I have cleaned this thread, and I don't want to see any posts about IMEI modifying or anything illegal here.
You can try stock flashing, rebuilding an EFS partition somehow (probably impossible) or repair shop, but any talk of anything illegal and the moderators will take action on your account.
Thanks.

Have you tried searching for a Galaxy s6 efs repair script?

If nothing has worked you definitely need to go with a repair shop. Either a third party repair or try to warranty replace your phone through Samsung. If you go the Samsung route Odin flash 100% stock firmware then send it in to them and see what they say

yeh i boght new s6 edge lolllllll bbut i i learned to back up

I bricked my S7... can it be fixed?

So I modded the hell out of my stock rom and eventually broke it. After failing to flash the stock firmware about 50 times I gave up and put Lineage OS on my phone. Eventually I decided I wanted to try putting the stock back on and somehow screwed up my IMEI crap and don't have a backup. Basically all my phone can do is run stock rom but without any mobile network support or the same thing with Lineage OS. I've spent hours trying to fix it but nothing's worked. I checked just about every guide I've been able to find and none of them work. the issue is either not fixed or there's some kind of an error/change during the process that makes it so I can't continue. I downloaded some combination file that is supposed to help fix the issue but it won't flash via ODIN like the guide says so i can't do that.
I really need this phone up and working again. Anyone got any ideas? As of right now I have a paper weight that I can browse the internet on.
Update: I fixed it by flashing Android 8.0.0 firmware onto my phone instead of 7.0.0. I'm not sure why that fixed it because even lineage OS couldn't get my IMEI number but it's working now.

So I modded the hell out of my stock rom and eventually broke it. After failing to flash the stock firmware about 50 times I gave up and put Lineage OS on my phone. Eventually I decided I wanted to try putting the stock back on and somehow screwed up my IMEI crap and don't have a backup.

Quickest way to solve the issue as you've found out is to flash latest stock for device. Bootloader was the source of your problems, once upgraded it cannot be downgraded no matter what. All these bull sh1t guides saying you can just end up with a bricked phone.
Now BACK UP your EFS partition so this doesn't happen again.

I am planning on install a One UI Based rom on my S7, my phone is running stock without any rood or something like this.
How to flash the Rom without making a stupid thing that will brick my phone? i mean how to start all the process from zero?
And another thing i wonder about, what is the IMEI thing that you guys talked about?

1. Go here to download TWRP an install it via ODIN,
https://twrp.me/Devices/Samsung/
2. In TWRP select backup and choose only EFS and back it up to your external card (preferably also to your PC)
that will backup your IMEI etc

I think you need to go tutorial section first. And start from scratch. You won't be able to find the cotrects steps on dumb luck. Thank me later.
