[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...

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..
Thanks

@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.

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.

This method seemed to work as i was able to boot into recovery cwm and go through the options. I then ran the supersu zip and verified that the appdrawer had it in there. things looked ok i thought. so now i was ready to download a rom. Attempted the most current CM10 nightly through recovery.- it failed giving me the status 7 error. i then went to the only post about status 7 in the all things tab 2 thread and attempted to download mobile odin but when i loaded the app it said not compatible with my device.
I then attempted to download a stock rom and remove root from phone because sometime in this all i lost the ability to use wifi and my imei showed missing in the settings. no attempt at unrooting seems to work because of the cwm not allowing me to use roms. I attempted to recover the nandroid i made the minute i "rooted" and its giving me the md5 sum error as well.

I'm worried for you, in that you have corrupted your efs folder - did you make an efs backup? as far as i'm aware, you can only recover your efs if you have backed it up. good luck.

If it helps I am an At&t store manager, and i do have access to a identical tab that is about to be sent back from a return. I am scared though of corrupting that one and then being in a worse situation. If i knew i could create a backup that could be moved to my personal one i would do it. is that possible? I'm not familiar with an efs backup but am researching it to check now.

I'm not sure it would, as a store manager you will know imei numbers are specific to each device!...you could swap the tabs over, but I don't condone that

Did you by chance rename the backup after making it? That has caused me problems in the past.

I totally understand what you mean now, i wasn't thinking a backup would switch over the imei i just thought it would contain whatever identifiers needed not realizing it would have the actual number in that.. I used total commander to look into the root file and there is a efs folder with all the separate folders "bluetooth, wifi, and other folders".

I did rename it when i was going through a fix for the md5 sum issue, i was going through adb and couldn't navigate to the folder so i did rename it... i cant imagine that the recovery would have an issue just because of that? i wouldn't be sure what to name it back to.
I wonder if Samsung has any option for me to send it in and get them to reboot the thing. This sucks!

i'm pretty sure samsung has an option for you to send it in, but depending on what firmware your running/whether the flash counter has increased in download mode - your warranty would be void - or you may have to pay some $$$$ - they may even refuse. i don't know for sure though.

if the counter is at 0 it sounds like you still have root access, do you?
you could try flashing a stock firmware through odin , which ever came with the tab - 4.0.4??? get the firmware from sammobile.com - that may :fingers-crossed: get rid of the modified status.

You're missing the point! He has a corrupt imei number. He can flash that but still won't be able to get signal.

I had a simaler issue with my S3 (d2tmo) as well as many others. Qpst I believe is what I used to get the imei back. I had the links all save on the laptop but it died 3 moths back. (10 year old dell). http://forum.xda-developers.com/showthread.php?t=1801997 try that out see if it will help. I have some of the other stuff saved that I will upload to you. Search the issue on S3 (us variants) it could help.

Samsung Rocks!
Great news! Samsung had me send it in and they repaired it in less than 2 days of having it. their ticket email says this
Problem found: ESN corrupted
Solution: Replaced PBA
-- not sure what a pba is but they didn't charge me for the repair! I'm taking this as a gracious sign from above that i should leave it well enough alone and enjoy it the way it was made! I'll just stick to rooting my s3 and doing what im comfortable with. I appreciate all your words of help and advice to try and narrow down a solution.

First of all, you flashed some things not meant for your device. the CF-Autoroot method is designed for the Pxxx models, NOT the SGH/SCH models. Flashing this on your device flashed partitions it shouldn't have.
Second, the PBA is the mainboard. I bricked my tab a few weeks ago (typo in my updater script) and they replaced the PBA also. Samsung warranty is pretty great. Glad you got it fixed.
Always, ALWAYS, be sure you flash a ROM/recovery/etc designed for your specific device. The pxxx tabs and sgh/sch tabs are 100% different in hardware AND partition layout. If you flash a ROM for the Pxxx tab on a SGH/SCH tab, it will overwrite imei. Moderators REALLY need to suck it up and create separate forums for the lte tabs.

I think the verizon Tab is the Xperia Pro in the Xperia Arc Forum

Help, deleted nv_data.bin

I was helping a friend to unlock his phone, and I accidentally delete nv_data.bin and dont have a backup. I know the original imei, is therea way to regenerate the imei? If I dont have backup. Please if somebody know i need help

Try one clicking back to stock

ok, i will download in my house, but, i was reading that one clicking dont touch the efs partition, and that file was there

Was the phone on gingerbread or ICS/JB? If it wasn't on gingerbread (Assuming it was a rom not based on CM7) you'll be able to restore the files by using a one click

the rom is in 2.2.1. Thats ok? I download T959VUVKJ6_STOCK-UVKJ6-One-Click.
So, if I use it, this will restore the nv_data.bin? I ask before doing anything because i have fear of make the this worse

Yes it will. Keep in mind that it will also factory reset your phone

I do it and gave me a imei thats only 000000000000000.
I insert the sim and work, But, this will give problems in the future?

No it won't. lol The OP is already on a BML partition structure. That trick only works if you loose it switching over to MTD.
Sorry OP your IMEI is gone and short of some fancy hex editing their is no way to get it back. Your phone will still work with zeros but data might be an issue. If you wanna try the hex edit way look in the dev thread for OLD unlock threads. Good luck.

So, i will have issue with 3g data or something like that?
I see a way that i can input the imei with a z3x box i think, and in my city there is someone with that box, that can work?
i search and only found: ;
REF] How to unlock SGS 4G or Vibrant 4G (IMEI Problems fixed)[Updated 11-19-11]
[Carrier Unlock] SGS4G AROMA Unlocker
I search in the dev forum. Do you remember something more about that post to search? :/

IMEI=0 restore with QPST, provided a QCN is available?

First things first, I'm sorry for opening another thread on this but I feel the other ones weren't headed exactly in the correct direction.
A little background:
I was trying to downgrade my XT1541 to Lollipop since 6.0 was really bad and I got frustrated and used
Code:
fastboot erase all
The result was I erased my IMEI and I haven't been able to connect to a network carrier since. The problem can be solved by re-writing my IMEI but that's the difficult part.
What I gathered so far is I can use QPST, backup QCN, go into HEX and change IMEI there, then restore the QCN back to my device. The problem is I can't locate the IMEI in my QCN since my IMEI is now simply 0.
So in all, could someone make a backup of THEIR QCN and send it to me? I would flash it to my XT1541, locate the IMEI (since now I would know what I'm looking for), then change it back to my own.
Does that sound like something that could work? Can anyone help?
UPDATE1: Noone sent me their QCN however I did try to restore the one I backup up (which still has an IMEI=0). QPST Software Download reports
Received an invalid command from the phone.

I tried using Qualcomm NV Tools (from EFS Professional), which reads all the information correctly, however when attempting to write the following appears
Cannot Write: NV_UE_IMEI_I
Error: NV_ERR_BAD_SECURITY_STATE

So getting another QCN won't help as it seems that I can't write the IMEI (qcn) back to the device...

There are only two possibilities of fixing this... a 50/50 chance that a full factory flash will restore it (don't know how, but it does sometimes). If that doesn't work, then you need to send it to Moto for repair.

Well, unfortunately that leaves option 2... or turn it into a media play and buy a new phone.
Funny how `fastboot erase all` causes such a pain for some and not others... but once your IMEI is gone, there isn't much you can do. Moto kinda screwed the pooch on that one.

Hello, did u try Xposed IMEI changer? Maybe that will be a native fix for this issue.

Try this >http://forum.xda-developers.com/moto-g/help/info-moto-g-imei0-t2925970/post61725547#post61725547

Hey, couldn't get any results with the xposed module

Just one bump

One last effort, not a bump. If anyone can direct me to commercial services for repairing the IMEI i'd be very greatful. Official Motorola Service wont repair it for me btw.
Thanks

try this guys
