[Q] Restore original IMEI?

Long story short, my imei is not the current one under the battery and i want to get it back. Before i thought my phone wasnt unlocked and that was the problem but its not. The phone is unlocked and i even have the codes, i just want to use my own IMEI. I currently can not connect to any networks with the captivate.
So far i have tried using the .bak file in /efs with no success (different imei).
I have tried several posts on xda but all seem to unlock and not give you your proper imei back.
Any advice or information would be greatly appreciated.

How did u manage to mess it up, may I ask. This way atleast u could warn the rest of the community not to mess ours up.

Its quite simple really, dont back up your /efs folder and keep messing around with roms.

I don't think anyone has solved this. Everything around the nv_data.bin file relates to unlocking and it says you must have a good IMEI number to start with. There was some 3rd party software that can fix IMEI numbers - but it required a separate breakout box. I forget the name, but many downloaded the software only to discover they needed to buy the box to get it to work.

One of mine managed to wind up with the generic imei but I have yet to see any ill effects from it.

I am sorry to hear about this, and even sorrier to have to say this, but xda does not allow posting of instruction on how one can change the imei.
Sent from my SAMSUNG-SGH-I897 using XDA App

Ok if we cant talk about this thats fine. Right now i cant connect to any networks. If someone would be willing to upload their /efs for me so i can try it out. Would that work?
Im in Australia so anything apart from that should work right??

did you ever got to restore your original imei?

IF THIS HAS BEEN SOLVED SOMEWHERE PLEASE TELL ME ASAP
sorry this is first post. Cheers
Hello XDA!
man ive nervous to post..
BUT i have come a null/null IMEI reading after a CM10.1 bootloop issue and trying to flash a new CM.
I have been a XDA follower for about 9 months but I have never needed to post for anything, as you have carried all of the lords answers. :angel:
I have done, stock firmware reset, Param bin, wiped all done it again. etc etc.
Many a conclusion has led me to probably a service repair centre.
I believe one option will still work for my IMEI restore but my phone comes up with a command that makes no sense.
Any help would be appreciated.
I am currently using QPST Configuration to write my IMEI back to my phone.
I have got these programs http://forum.xda-developers.com/showthread.php?t=1804117
Aswell as another handy IMEI converter to make sure my IMEI HEX conversion correct. (sorry cannot link. cannot find)
I have been using QPST and can follow all steps, except my phone WILL not show on on active phones.
I have reinstalled drivers and followed all necessary steps.
I have tried it in recovery mode also in QPST and no active phone still.
I believe i can get this to work, just need it to recognize my phone, and ill write the IMEI and hopefully..
Voila.. i can call the GF and tell her to chill. :good:
IS RNDIS different to RNMET? (how big of an impact will this play on the process)
In qualcomm settings i get "RNDIS + DM + MODEM" but i do not get "RNMET + "

Changed imei

Is it possible to changed imei

I got a problem with my phone (G800F) my imei has changed. I don't know how but it did..are there any solutions to fix this ? I don't know what to do now.. now it will not connect to network

Think you flashed a rom with another CSC as original, or? Also think you do not have a EFS backup...

I didn't make a backup.. because I did not changed the rom .. that is why I don't understand why the imei has changed... If I put the imei on the website imei.info it says Nokia 6310.. I think I must wait for people to create a program to fix this .. or are there already solutions for this??

hi, i have exactly the same problem. Did noting and suddenly my imei has changed.
Afther hours of researce i havent found a working solution . Is there a way to change the imei back to the original one?
-Samsung S5 mini / G800F
Things done after the problem appears
- rooted
- installed cm13 beta
It would be nice if somebody can help me

mine too

Yeah, thats exactly the samething happening to me! What the hell is this? You guys remember if you also got a myserious call from ukraine around that time?
So this is a bug?!?

Well, ok. I don´t mind. I dont see how i can fix this and nobody is willing to help me. I´ll just buy a new s7.

Hi All,
Did any one actually get a fix for this issue as I have exactly the same problem, my SM-G800F IMEI now also shows as - IMEI 350695200123951-01 which is for a blacklisted NOKIA 6310. If anyone can supply an absolute beginners guide for me as to how I can get my original Imei back that would be fantastic.
I am just a user of an android phone and have zilch experience of tinkering with them.
I have seen reference to things like Odin and flashing firmware and am quite happy to give it a go myself and learn
I will post this on a few other threads that list the same issue as I am desperate to get this fixed now as is a waste of a perfectly good phone !!
Cheers.

[Q][GT-I9305] EFS, IMEI Repair

Okay everybody,
I decided to write a new thread for my problem because I think my prob is a very special thing.
I'm from germany, so please don't wonder about my english. I think it is a understandable.
The story begins with a software update for my GT-I9305. After the update, the IMEI was just "null", after some work with google I found out that the efs partition was broken. With my bad knowledge for this case, I destroyed the whole EFS folder. I installed perseus kernel. And, there it was! The whole and correct IMEI. The solution was the perseus kernel (stock doesn't work, neither reflash). But then, after a while the phone doesn't boot anymore. I flashed Android 4.4.4 and my phone was revived but the IMEI was again "null". I have no backup or anything else!
So I spent approximately 20 hours or more to understand the efs thing. I found much solutions but nothing worked for me. So, here I am.
What I've tried before
-reflash KitKat
-reflash Perseus (not compatible anymore)
-formatting efs partition for a blank and new EFS for editing
-tried to edit nv_data.bin with HEX
-tried to backup efs with a 3rd party app and edit this with hex (the app doesn't support my GT-I9305)
and then, there it was:
-tried to use a working EFS partition from another GT-I9305
-editing with Qualcomm NV Tools! (I think THIS is the solution!)
I tried NV-items_reader_writer (1.0) and EFS Professional (2.1.73), but in both can't find my phone:
What I've done in NV-items_reader_writer
-dialed *#7284#
-at "Qualcomm USB Settings": "RNDIS + DM + MODEM"
-enabled USB Debugging in phone
-connected the phone
-opened NV-items_reader_writer
-checked the both boxes near the SPC box
-selected the right port (last: COM4)
-clicked on "connect"
-clicked on "read"
-> here it search the phone, but it can't find it and says "Failed.. Phone does not answer"
What I've done in EFS Professional
-dialed *#7284#
-at "Qualcomm USB Settings": "RNDIS + DM + MODEM"
-enabled USB Debugging in phone
-connected the phone
-opened EFS Pro
-clicked on "Qualcomm NV Tools"
-refreshed the Available COM Ports
-selected "SAMSUNG Mobile USB Serial Port" (last COM4)
-clicked on "Connect"
-> Here it takes few seconds and he stops and says: "Phone connection has been lost!" and "Unable to send SPC to the Phone!"
What I've tried to solve this problem
-tried QUALCOMM USB Settings: "DM + MODEM + ADB"
-reinstall all Samsung drivers
-tried to install Samsung Modem with Qualcomm drivers (failed due to wrong platform; I've Win7 X64)
-reinstall Samsung Kies (for actual drivers)
-tried to dial *#9090# (in my case, this menu is totaly blank)
-tried in factory mode
It could be that I forgot some....
Now, my question to you all is, do you know what I've done wrong? I mean, this is working for the most users, but why not for me? What do you think? Did you think I really forgot something?
Some informations:
Phone: GT-I9305
Android: 4.4.4 KitKat
Kernel: Stock (3.0.31-2760029 ; [email protected] #1 ; Fri Sep 12 13:08:24 KST 2014)
Buildnumber: KTU84P.I9305XXUFNI3
Windows: Windows 7 X64
Do you need more informations? Post it!
Please help me, I want to bring this phone back to life!
And yes I know, to change the IMEI to a number which is not your own is ILLEGAL and to prevent this, it is not well seen to talk about, but this is MY PHONE and I want to change the "null" IMEI and IMSI to MY ORIGINAL IMEI. If this is a problem, I can send a PM to an mod with my phone (where you can see the IMEI), my username on a sheet of paper and the original box with the IMEI printed on. All on one picture!
Simply... I need a hero! Be MY HERO!

im in the exact same problem as you. the reason nv tools and efs reader is not seeing your phone is because you have NULL well usb wont work. so try installing the original 4.1.1 firmware, then install perseus, then nv tools and efs software will see your phone. if you end up fixing it please help me out. upgrading to a later firmware is where I get stuck. just stays on the boot logo. and like you said perseus isn't compatible. you seem to know how to use nv tools so hopefully you can get somewhere. as I don't no how to use it. GOOD LUCK.

take your phone to the samsung if you have warranty.otherwise give to a phone repair shop for repair because your problem can only be solved with special boxes and equipments etc, and they have it. it will not cost too much.

I tried this, already. But I can't downgrade from 4.4.4. I don't read very much about this. I just know that this is a new security option from samsung (or Android)... I will tell you when I know more

The warranty is already expired...
This will be the last step I will do. Before this, I will try my very best to do this at home... But thank you for this tip
Edit:
What do you all think about this idea:
-I try to find somebody with a working EFS on GT-I9305 Android 4.4.4
-I get a backup from him
-I restore this backup to my phone
-I edit the duplicated IMEI with NV Tool to my IMEI
This requires that the NV Tool will with work with an existing IMEI and the the phone will be THE WHOLE TIME IN PLANE MODE to prevent IMEI ban...
What do you think? Will this work? Do I need somebody from germany (DBT) or is this not needed?

Take it to a phone repair shop they might have a way to fix it. And if they don't they might know someone who can and it would likely be cheaper than Samsung service center

I flashed the old bootloader so I was able to downgrade to Jelly Bean. There I installed perseus and now I could connect to the Network, but I don't want. IMEI ist still 0.
But now I can enter *#9090# menu. But I can still not connect the phone with any DM Prog

If you were to 4.4.4 Official Stock rom can`t do downgrade the bootloader.What you have done is downgrade to Firmware with extracted knox bootloader.But you still with EFS corrupt partition.

Hm okay. I applied a "old bootloader" before here from xda. I don't know what it was exactly. There was a boot.so or so in it.
I will try my best. I mean, if I can beat this, this is a really great success for me. My next step is to restore a full NAND backup from a friends of mine (from a GT-I9305).
I wondered about that, after I restored a working EFS, there were no NV data.

Hi guys, i had the same issue: after a botched restore of nandroid backup (something to do with it being over 2GB, different story though), I lost IMEI (null/null) and no baseband.
I was running CM so I tried to flash the original Samsung ROM, to no avail. Then a whole bunch of other stuff that didn't work, until:
- I flashed kitkat (which failed due to some error in the install script, dunno why)
- then flashed my last nandroid, which I had already flashed with no restoration of phone functionality, HOWEVER,
- I then flashed over that nandroid the modem files (see here: dropbox.com/sh/d2ljv1ylvr9nvib/M7UzMgux4f) , mine was Modem-I9305-XXUENE2.zip for i9305 LTE Intl.
- tadaa! fixed
hope this helkps anyone, took me some 20 hours of tinkering

[solved] IMEI Recovery help! Lenovo K3 Note

For the past half a year, I have been using Carbon rom on my Lenovo K3 Note, and it was fine, until it started slowing down. So, I decided to change it to another rom (Nexus), and the next thing I know, my SIM card is no longer detected.
Turns out, the IMEI was wiped.
How would I go about restoring this?
The things I have done:
MauiMETA = Never detects my phone. Places it into meta mode, but the light never turns yellow. Tried on 3 computers, and had no success on getting it to work. For two of the three, I couldn't find drivers for mt65xx and CDC.
MTK Droid Tool: The option to change the IMEI remained permanently greyed out, and was never given the option to change it.
Official rom: Didn't work. Currently using it, and still the same error (Null). Tried factory resetting it, no change.
Engineering mode: Always gave me an error when trying to enter command, never accepted it.
IMEI.EXE: Everything worked, except the IMEI's never changed in my device.
Have tried multiple roms, multiple wipes, SPFlash, CWM (Even ended up installing it again because I wiped my entire phone with SPFlash), and pretty much every trick I could find.
I need this think working in 12 hours.
EDIT: Problem was resolved with trying "official" roms until one allowed me to update within the rom. The Update that was installed via Lenovo's bootloader fixed it. The finished product was that of an untouched phone; I had to reinstall a bootloader, root, and a new rom.

If flashing stock doesn't help, and you have no kind of backup of where the imei resides, you likely need a service center to hopefully help.
But know that any talk of manually inputting imei numbers is not allowed on XDA, as its illegal in most areas.
Good luck!

So it isn't as simple as entering the two codes under my battery into some location, and rebooting?
I'm currently in Europe, and have no idea how any of that works (Studying abroad).

That talk is not allowed, as I said. Inputting numbers falls under tampering and is illegal in most areas, as I said.
So try flashing stock, if you can. But without some sort of backup, you may be out of luck unfortunately.
Please keep number inputting talk off XDA, or I will need to close this thread. :good:

UPDATE: So, I flashed another "official" rom, which initially didn't work. However, it did give me the option to upgrade, which I did. With that upgrade, the IMEI is back, and my SIM card works.
Thing is, the ROM is almost entirely in Chinese.
How would I change my rom without wiping the IMEI?

Please post the link to download the ROM you used.
I have the same issue and even service centers failed to attempt this.
Thanx and regards

You can easily rewrite imei number using snwriter tool, google it.
