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] One Week trying to save a P920 and Failed [ Help Appreciated ]

Hello Everyone,
So I've been dealing with a P920 for the last 7 days trying to Flash it and it's not working.
1- Device is booting to Android but all applications are crashing ( unexpected error com.x.x ) force close.
2- I tried LG recover mode, phone flashed but once successful and rebooted, same error upon loading desktop.
3- Tried rooting the phone with SuperOneClick2.3 ; Rooting successful, upon reboot, rooting is lost
4- Downloaded KDZ original firmware V21A Europe based from lg-firmware site and used offline installation ( shttps + modified host file etc..) . Installation successful and flashing is OK; rebooting = same error on startup.
5- Downloaded firmware V10B and flashed it successfully. Rebooted, phone version is still showing V21A !
6- Rooted phone + installed CWM -> successful, rebooted, it's gone.
Now this is the first time since 10 years that I get into such thing and the device is getting me on my nerves.
Any idea or advice is much appreciated!

Well
Looks like a hardware issue. ROM, RAM, Internal memory. U need to find a way to delete partitions and re do them somehow. Have no idea if there is a software for that. I had it for my SGS. It should help.
Just repartition whole internal memory.
UPDATE:
Here you go ! Good Luck ! and tell us did it worked for you
http://forum.xda-developers.com/showthread.php?t=1509195
Remember not to switch internet with external memory or u will brick it totally!

Great, I will give it a try thanks.
Do you think I will have to delete all partitions and create them again ? or I should only specific ones ?

Have no idea. Try to make some research I don't want to give you wrong answer. Should be only one where rom data is, but I'm not sure.

Hello MinedSafe; As I mentioned earlier, whenever I root the device and reboot, it's not rooted anymore. It is not possible to install CWM ( changes are not applied )
I have managed to root the device and tried the parted command, I get command not found.
I have noticed that once I get into the stock recover and wipe everything, I do not get the first welcome screen to setup the device, it's booting with the same error.
I have started to lose hope. Device is no longer under warranty

Have you try to recover it from LG mobile support tools ?

It looks like the partitions are damaged or eprom/rom ( no commands ) memory is gone. So the only way is to send this to LG service where they can upgrade/rapair with their 'hardware' tools. If you try on you own you might get to a stage where even they wont be able to fix it.
What kind of software you where putting in to it ? Froyo or GB ?

Another person, so its now more likely then when upgrading the partition table was screwed up. It could be a mistake in addressing the memory when flashing.

First you must search LG service in your country. They are everywhere.

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

I was trying to flash slim bean beta 2 and encountered the same problem.

@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.

!! imei 0 !!

Hi
I don't know how but my imei has been deleted
I flash back the stock firmware using rsdlite but it's the same
There is a solution to restore my old imei ?
edit
Rom JB --> Rom ICS --> imei 0 --> recover it http://forum.xda-developers.com/showthread.php?t=1960918

Yes, you can repair the IMEI using RadioComm or QPST to write it back to NV Item 550 NV_UE_IMEI_I.
You need to use DIAG mode access to read/write to the NVM(Non Volatile Memory) of the radio chipset.
I don't have time before work to write up the complete method, but you can definitely fix this and I will try to post the method with links tonight after work.
You will need the latest version of RadioComm and Motorola drivers installed on your PC or QPST 2.7 build 378 or later.

Thank you it would be really great to do that! I think it's going to happen to other people too
So I try and if I can't restore my imei I will exchange it against a new tomorrow

I am not certain it will work on your device with this chip set so I am discussing it with a knowledgeable friend.
I don't have an HD, I have a dev edition Razr M, so I can't verify everything myself for your device.
Edit: In the meantime, it would be a good idea to explain everything you have done leading up to this so we can establish better information about your circumstances for other users.

wipe data, wipe cache, flash ICS SFR rom with rsdlite, I tried to root from recovery with .zip (doesn't work), root with motofail2go, and update JB from recovery (root ok)
I think maybe it's because of that : when I flashed ICS rom with rsdlite at the end of flashing the phone reboot alone... so I unplogged it without waiting the "finish state" on rsdlite...
Stange thing, the phone still worked some hours although I rebooted it several times
The night, no network, and I saw that I had no imei
I hope you enjoy my "google trad" English :cyclops:

i have do the same and i don't have any probleme with my iemi.
PM me for how you get root with JB.
Thanks

Update: After more research, it looks like I was wrong and it is not possible to write/repair IMEI on this phone, at least with the tools we currently have.
I have spoken with a good friend and tried myself in various ways and the NV Item is read only.
I suggest you return your phone. Although it's possible we may find a solution, it is not likely to be in any time frame you would be willing to wait for.

Tried plenty of flash/wipe combinations, but can't get my IMEI back...

All right, I give up... Returning the phone to Motorola...

I changed mine on the coming week.
I am disgusted.
it will do a very good mp3 player ......... *PAN* *Head Shot*

The fact that it can be blanked by some bug suggests a vulnerability itself, so there is some hope for a solution.
A similar bug has presented itself on the Samsung GS III but because Samsung security is much less "secure" on their devices, it can be fixed by various NV access methods.
Motorola, for better or worse, has always had much more rigorous security protocols on their devices, in particular relating to ESN/MEID/IMEI repair.
If we can learn the mechanism of the bug that corrupts/erases it then we may learn how to fix it.

Flash back up to JB, IMEI will still be 0 but radio will function again

My IMEI is currently @ 0 however with the JB upgrade, I can, at the very best, establish a HSPA+ connection.
LTE (although shown as an option) no longer works.
I'm curious if this is something that could be resolved with Cygwin & Dsixda's Kitchen (e.g. use the JB modem firmware on ICS)?
Best of luck to everyone with this issue. Hopefully we'll have a resolve in a few days.

[EFS corruptes] S8+ G955F

Hello dear users,
I`m facing a very big problem with my g955f. For a while i had 7.0 on my device but yesterday i decided i should update to 8.0. I flashed the latest 8.0 stock (BL, AP, CP, CSC) from sammobile and everything worked great. Problem appeared when i tried to install supersu and it got into a bootloop. I flashed again 8.0, this time without BL because i've got the error "SW REV. CHECK FAIN(BOOTLOADER) DEVICE: 2, BINARY: 1". After device booted up there was NO IMEI...s'o i think something happened with efs partition. Then i tried a fix from another thread and now i get "efs mount failed (invalid argument) after i flash a rom and the phone restarts".
I know i know, i should have made a backup...
The question is, does anybody know how to solve this problem ? Maybe from where to get an efs dump (even with IMEI 000....)
sorry, my english may not be so good
Thank you !

i finally found a combination file for U2 bootloader version but no success. Someone more skilled than me told me that efs partition seems to be effectively deleted. I'll take the phone to a service today and hope this will be solved. Thank you
LE: can you explain what this pit file is for ? i don`t want to brick the phone more than it already is

maybe you`re luckier than me and your efs partition is just corrupted not deleted and combination file will fix it

How can i check that? Do you fix your problem?

No.... still not fixed because efs partition is deleted. What is your phone actual problem ?null imei or it doesn't even boot up ?

I have this stock S8+ Official Oreo CRAP Firmware 14.02.2018, but i can´t find the combination files for it.
It does boot up, but it doesn´t give signal and when i look up in settings for the imei it says unkwon. How can i be shure that the efs partition is deleted?

Oreo comes with U2 version of bootloader. This means you can`t use combination files that have been made for 7.0 bootloader (U1). Yesterday i found a combination file for U2 version. I'll share the link with you but right now i'm at work and i don`t find that link. When i'll be at home(8hours) i'll post the link here(i saved it in bookmarks). Chances for recovering your imei are very high i think. Until then please don't make something stupid with your phone like i did....
LE: if the phone is booting up then i think your efs is just corrupted

Yeah....i`m desperate too....i messed up an expensive and a high end phone.....but that's it....we're learning from our own mistakes ). I think that is the file i'm saying (check if it has "U2" in its name). Download it, flash it with odin (put the file in AP), wait until the flashing process is done and that "gears screen" is on, and wait. After that flash the stock 8.0 oreo and the imei should be back. Hope this helps you. I can't give you an exact method to see if efs is corrupted or deleted.....like you i'm a newbie with all this architecture of android...

I used the combination file and show me the imei so i think it was just corrupted. But when i try to flash stock in odyn https://forum.xda-developers.com/galaxy-s8+/development/rom-galaxy-s8-t3749444 this version, it says device 2 binarie 1 error. So flash without check BL. But then the device doesnt boot and gets stuck in first screen. What can i do?

There`s nothing you can do. Your only option is to stay with 8.0. You can't downgrade the bootloader from U2 or U1 because U2 security policies seems to not be ok with this ). I left my device at a service twenty minutes ago to reflash an efs dump from another 955f....hope they will make it.... anyway, congrats for reviving your device

This message means that your actual bootloader version is newer than the one you want to flash and because security policies you can`t flash an older version. You'll have to flash latest stock 8.0 (bl,ap,cp,csc).
