hi Guys,
First, I apologize for that I'm doing the hundredth post on this topic
and secondly, I apologized for my "google translator english" (unfortunately I can not so good English because I am from Germany)
to my problem
I had the "Cyanogenmod 11 nightly" ROM on my Samsung Galaxy S 3. By the time the system was slow and I have flashed the latest CyanogenMod Rome via Odin on my phone. After the reboot, I had no connection to the mobile network, my serial number consisted entirely of zeros and my IMEI was not like it is in the battery compartment.
I have now spent several days trying to find a solution but for all IMEI Restore tutorials have not brought with me. Unfortunately, I did not know much about even before the Android system per se and the EFS folder and have therefore no backup.
I tried the IMEI
restore the NV_data.bin + NV_data.bin.md5 methodResult: IMEI was still so wrong seem right that my IMEI is no longer located in the System
restore with the downgrade to a German MG6 Android versionResult: IMEI was still not rightrestore using tools like QPST + nv ReaderWriter or EFS ProfessionalResult: EFS Professional -> Qualcomm NV Tools (after efsprofesional the mobile phone has put into the correct USB mode) -> connect to my phone broke off as soon as I wanted to read or write
QPST + nv ReaderWriter -> gave me appear not correct port on my phone
all the drivers I have installed clean and tidy. After further investigation, I found out that I need a special UARTcable this (and maybe a Z3X Box or something similar?)
My question is
How can I get now establish a new nv_data.bin file that includes my right IMEI
or whether (if it is really expensive) someone is so net and created me such a file
my Hardware is Samung Galaxy s 3 (i9300) (unbranded) (may u need this too: i bought it in germany)
I only want my own IMEI and I do not think out a like or I like to personally via PN or so to sample photos (for example, a predetermined word from the person) and the battery compartment of the phone with the IMEI
for I illigalität knows that it is illegal but not his own restore its IMEI change, because you paid a lot of money for his mobile phone and the IMEI is jointly contain. Who's afraid these publicly to write here because this information could be misused can I enjoy writing via private message. I would be very happy
Now im trying again to solve my problem with this Tutorial -> https://www.youtube.com/watch?v=XT42ri37RBU
my preperations:
im installing now a fresh windows 7 on my Laptop
i flashed I9300XXUGNG3_I9300DBTGNG2_I9300XXUGNA8_HOME.tar.md5 (SGS3 Stock Firmware DBT with android 4.3) downloaded with the SamFirm tool from http://forum.xda-developers.com/galaxy-tab-s/general/tool-samfirm-samsung-firmware-t2988647
i rooted my phone with Odin3 and CF-Auto-Root-m0-m0xx-gti9300.tar.md5
i put the usb debugging on (settings > options > about device > [clicked 7 times on Buildnumber] that activates the developer menu and i put usb debugging on in settings > options > developer options > usb debugging)
i´ll post the results
dont work for me becouse "ONLY for US variants. It DOES work on Qualcomm CPU and DOESN'T work on Galaxy International Version with Exinos CPU!"
someone maybe got antoher way to fix it?
@sLeCks:
1. Flash last firmware with Odin (again), go to recovery immediatly and do factory reset.
2. If 1. doesn't help, try Ariza patch.
3. If 2. doesn't help, let it repair by Samsung-service (cheap).
Firmware Update dont restored IMEI (got still 0049 imei)#
Ariza patch wont help it just restore the baseband (like written in the Thread "wont help if u goot a 0049 imei)
maybe it works if someone got a i9300 (intl) (exynos NOT Qualcomm) and a z3x-box or another. i send him my right imei-number he backup his efs folder and create the right nv_data.bin file for me. then he send it to me via email or he put it on uploadet in ecample. i download it in put it on my phone and restore my imei.
maybe i think is a full efs.img backup file better xD. if this way work it would be the best i think.
Ißve called some mobile reperature stations an mony of then dont do an imei-restore. i got one and go now to him maybe he can help. but if someone got a box and a old sgs3 i would be sooooooo happy if he could help me.

Hi guys.
Here`s my problem.
My brother bought an international variant of the Galasy S3, i93000 a couple of days ago from an online auction website. To make the story short, after trying to figure out why the device isn`t connecting to ny carrier, I found that it had a generic IMEI. Go figure, got the same problem earlier this year with an SII.
The previous owner flashed it a few times, as it came with a variant of Jelly Bean, XXDLH8 I believe.
Flashed a stock open europe ICS (XXBLG8) and rooted it but still have the generic IMEI.
I found some threads online on how to rewrite your IMEI code back, since it is written on the back of the phone and on the box, but it only applies to the Verizon version of the S3. I need to access *#7284# and select something that isn`t there on my device. And using a piece of software called NV reader/writer, you edit your IMEI directyly on your phone. It has to be put in the correct form, but it is possible.
My question is, how can we edit our IMEI code on the international version of the SIII ? Don`t get me wrong, I don`t want to modify it all the time, just trying to get it back to how it was.
Sending back to waranty isn`t an option as the previous owner bought it from another country, and also he now refuses to answer my calls.
I`ll have to mention that the device isn`t stolen, it has the Samsung generic IMEI, which wouldn`t be a problem ig it wasn`t blocked by my carrier.
I know have a really expensive device that isn`t more than an iPod. My brither doesn`t even want to see it anymore.
It has to be a way we can restore our IMEI via nv_data.bin and a HEX editor.
You can not be sure that this phone wasn't stolen. Previous user could wipe or modify efs partition to not be tracked by IMEI. Or he just broke efs while flasing and sold the phone because he couldn't fix it.
The warranty is valid throughout the whole European Union, not only in country where the phone was purchased. But you did not write where the phone was purchased nor where you live.
You can serch your internal sd card, maybe there is a backup of efs folder. If not, you can try to use some tools to restore correct IMEI to nv_data.bin from .nv_data.bak (EFS Pro or similar).
You could also try this manual solution:

Hi there.
Yes, I can be sure that the phone isn`t stolen as it has all the necessary paperwork to prove it.
Regarding your suggested fixes, I`ve already tried the first one, restoring from the .bak files with no success.
Also I read the second one earlier and I can`r apply it as my nv_data.bin file doesn`t have even have the lines mentioned in the tutorial. It says that I have to edit line 0188008, but my files goes from 0188001 straight to 0188014.
I`ve found a tutorial over at http://forum.gsmhosting.com/vbb/f606/tutorial-galaxy-s3-backup-restore-imei-without-root-1513909/ (sorry for the external link if they aren`t permitted) but it applies to the Verizon version (I believe) with the Qualcomm cpu. When I dial *#7284# on my device I only have the 2 sections with 2 options each. UART where I can select Modem or PDA, and USB with the same two option. Because of this, the app NV reader/writer can`t access my device.
First I'm so sorry if my question is similar with another threads. But I'm pretty sure I have been looking for the answer around the internet and of course XDA developer for a week. I follow every guide and method I found. But it still not answer of my problem.
I flashing camera driver I've got from my friend backup using TWRP backup. Actually I only need to choose uboot only to install. But I'm in hurry so I accidentally choose everything includes NVRAM. Since then I've got wrong IMEI on my phone because the IMEI overwritten with my friend phone. But it's not a problem because I can restore my original IMEI with MTKDroid & Tools.
And the problem is my IMEI is now back and corrected. But there is no network detected on the phone. SIM card detected fine. When I go to EngineerMode by pressing *#*#3646633#*#* and open Radio Information on CDS I saw IMSI field was unknown and Radio Status is turning on and off rapidly.
What I have done is :
1. Full flashing with the stock ROM via SP Flash Tools.
2. Change the IMEI with MTK Droid Tools
3. Change the IMEI with AT command ... echo 'AT+EGMR=1,7,"myIMEI1"' >/dev/pttycmd1
No result. IMEI is correct but no network.
I believe this is not a hardware problem, so please help me to solve this problem. Because it's my only phone to communicate with my whole families. I really appreciate with your help. Thanks.
Hi, this post is for everyone ho have big problems with the samsung galaxy s3 like me. My nature is to be curious, thats why i install many roms and custom roms and after that in the morning i bricked my phone. The imei it was 0049..... and serial number a number not throught. Practicaly my phone it was like a media player because wifi its working. I try many metods but without luck. In the past i make a backup of efs folder but after many metods of restore .... no imei. I look on my phone and i want to jump over his had ). After i smoke a tigarette on a site i see e simple metode. It is an aplications CHIMERA PHONE TOOL . Take a look on site : https://chimeratool.com. What do you must to have is to pay 12 euros. Is not to much because for go to service i think we must to pay much more. The program is very simple.
- Connect with USB DEBUGING ON. I hope you install the drivers for s3.
- The aplications (if you pay) show like this in the picture below.
- You have many posibilities: root unroot, flash new firmware from the zone where is the phone located. Its nice because for me is not important witch csc kernel modem bla bla bla i have. Important it was to working very good. You can repair imei, serial number, and.... MAC adresse of wifi and bluetooth.. nice. And not for the last place , you can UNLOCK the phone.
Dont make like me, first you must to flash firmware beacuse its better to be stock and new and for not have errors on writing imei..After you flash the rom you must root and after that write s/n and imei. By mistake in the morning when i erase imei i erase also the serial number and i dont realize that. Its very important to verify on settings if you have S/N like on the back of the phone near imei. After that the phone is working without any problem. In the past every time i flash something i must to install pached kernel and modem of ZULUMAN to working. Or ariza patch . Good luck, if you have problem write here.
Hi everyone,
I come to you as I am a noob as far as twinkering with my gt i9300 goes and I think I messed it up big time.
Here is what I did :
I had android 4.2.1 on my gt i9300, the stock rom from sfr (french career).
I network unlocked it using my career official unlock code, which worked great. It recognized my japanese career sim very well (i am in japan now).
Then I got greedy and wanted to update my android version so I downloaded a 4.4 android rom from I don't remember well, and a cwm manager.
The network unlock worked fine at first but after a restart it did not work anymore. It asked me for a network unlock pin.
I thought it was asking for a sim pin at first, which my sim did not have as I hadn't set one. I got mad trying sim pin code and gave up. Had I given it the network unlock code instead of possible sim pin code it might have worked but I will never know.
Then I tried to solve the problem installing android 5.1 cyanogen version but I had the same problem except this time I understood it was asking for the network unlock code. The problem is that when I fed it to him, it did not work, the request was unsuccessful.
So I looked for a solution on internet and found all kind of things:
I read about restoring the efs partition, but i do not have any back up.
I read about installing a stock rom version, change the csc and retry the official network unlock code, but it does not work, whether I restore through Kies (which gives me a vodafone version) or manually (with an sfr version, french vodafone it seems).
I read about installing Galaxy simunlock app after rooting the phone and installing userbox, but it tells me that my locking system is not handled as it is too new.
I upgraded, downgraded, rooted in every possible way but nothing works.
I am running out of solution and I therefore turn to you for help, hoping you will be more creative than me.
I have the official network unlock code, the phone, no back up of any kind and really little hope.
Thank you in advance for any help you could give me !
Have a nice day !
Sadly you didn't make a backup of efs. That should be first thing before playing with customs.
Oh well, I suppose your efs may be screwed up due to entering couple times bad network unlock key.
I suggest go to next corner GSM shop and pay 2400JPY for efs fixing and perm sim unlock. But before that, check your IMEI and serial number are correct. Thay can fix all of this in one step.
You need to do this via box, you can't reprogram that or fix yourself because you did everything that may help and you still have a problem. You can't use any software on efs v2. It will not work.

Thank you for your quick answer !
I will follow your advice and go to a "professional".
However I don't understand how they are able to do what I can't, do they have special softwares or anything ?
I would like to know because I do have the official unlock code.
Also, I would still like to upgrade to android 5.1 cyanogen version, do you think it will be possible after such a modification ?
I should not encounter any risk if I backup the efs beforehand right ?
Thank you again
Service will connect your phone to, so called, box, ie Z3X Box. This is some kind of pc-phone bridge hardware which can alow to decrypt and encrypt efs files, fix IMEI, serial number, flash firmware, IMEI certificate, remove network locks, sim locks etc.
Of course you can backup your efs now but it is corrupted and useful. Backup this partition after repair. Than you will be able to flash anything you want. Even CM12.1,no problem.

Ok I understand better now.
Thank you very much for your answers, they have been really helpful !
Do not let them plug your phone to the box if you want to install 4.4 or 5.0 because if you give them they will replace your imei number with a clon imei number and you will stuck with max 4.3 and you need to install a patched modem and kernel every time you format your phone... tell them to try to fix without replacing your imei number first. Replacing the imei number should be the last thing to do...
Why do you think they will clone his phone's IMEI? It's even illegal.
If someone doesn't know how to use box than he should not work in GSM service.
You can rewrite original IMEI and serial number without cloning anything.
An probably IMEI is fine, it's network lock problem.

Most repair shops dont care its legal or not. Also most costumers dont know this kind of things and as long as phone is working its okay for them. Mine is just a warning to make him look like he knows this things so repairman doesnt do something with no going back...
Messed up with my G925F!!!
Hello , my phone suddenly was not able to make or receive any calls or joining 3G/4G network or SMS. In other words, I was out of service although my SIM had not problems to enter the PIN password and I could see signal bars.
After a little research I discovered that my IMEI and S/N number had been changed! Especially, the IMEI number became 350000000000006 (fake one) And I believe this is the reason my signal went off!
So , I just managed to download smart switch from samsung and choose "emergency software recovery and initialization -> device initialization" in an attempt to revert it to stock rom and settings (is this method unroot the phone too?)
But after this long downloading finished , the phone didn't boot , I only see the samsung galagy s6 edge logo stuck!!!!
So , I decided to root the phone again , following the guide here (link-->), zidroid.com/how-to-install-twrp-root-galaxy-s6-edge-on-android-5-1-1/
(in short words , I installed the twrp recovery with odin and I flashed 2 zip files required, from an usb-otg-flash drive, via the twrp recovery install button) and then the phone booted normaly , but the problem with the signal and wrong IMEI was still there!
I feel that I am on dead end , I don't know what to do , I am thinking about sending it to the location I bought it but I am afraid that the warranty is lost.
Please help me restore my phone back to normal
After repeating the whole procedure several times , now my phone does not recognize SIM card at all , as if it was never inserted , wtf?

So you mean that there isn't any way of backing up the IMEI number first before rooting or changing a rom/kernel/recovery to the phone in order not allowing this IMEI bricking happen again by means of restoring from its backup?
I googled a lot and some people suggest that they can backup EFS in some way. What is EFS exactly and how it is related to IMEI?
Also wouldn't be a good idea to find a way to backup my entire OS/firmware (not just IMEI/EFS) before doing anything , in case to save money and avoid the same bricking?
And yes , I have sent the phone to samsung service , it will cost me around 320 euros , because they discovered I changed kernel/rooted the device , and they will change motherboard.
I cannot help the phone without being rooted , I love rooting but I cannot understand why suddenly IMEI got bricked.....does it worth to take risk and root my phone again? But I want IMEI or entire OS backups first before doing that and I don't know how to achieve this without rooting first...
Please help me if you could.
You can backup your full os using twrp recovery
Also your IMEI
In SAMSUNG devices imei number stored in efs partition that's why people asking take efs backup before flashing any Rom

Me too! I have the exact same IEMI number! Mine stopped working after about a month. I tried to return to seller no response. I tried to send phone back they would not accept phone, so it is on it's way back to me. Once I get it back I will try what you did.
I have taken it to factory settings 3 times no luck. I will try your process once I get me phone back.
Thanks!

I did contact one of those fellows a reputable one that can change your IEMI. Well once he heard that crazy IEMI number, he said because it was changed once before to something like he doubted he could change it again and save my phone. To try he charges 100 US plus I have shipping there and back. Yikes.
So any advice you can give me I would truly appreciate.
Thanks!

Mine went down recently with the exact same IMEI and no SN. TWRP was failing to restore the efs partition damaging the files in the process. Long story short, I had to manually extract the efs files, copy them across and fiddle about with permissions but I'm working again.
That nugget rings true - always backup the efs before changing anything.
But for that reputable fellow to say that the IMEI had been changed before because of what it had become, and insinuating that the imei couldn't be changed more than once was complete twaddle. I wouldn't trust him near any of my phones.
On a lighter note I'm sure there's got to be a member on here would sort it for beer tokens
Happened to me, I thought it was faulty ROM and all but then I realized it was simply apn setting. Resetting it to default did the trick. It can be found in Settings > Mobile networks > Access Point Names

Since this thread is quite old and people keep answering , I want to end it like this:
Back then I didn't avoid to pay about 300 euros to replace its motherboard to a samsung shop. But I learned lately that the issue was due to an app called "USB OTG Helper" (https://play.google.com/store/apps/details?id=net.shajul.usbotg&hl=en) which allows you to insert NTFS USB flash drives to your OTG phone but also enables a system partition , including EMS files to be visible.
And you can guess what happened next , I deleted this system partition which this app made it visible and yes , my IMEI was gone!!! After some months , I repeated the same delete thing , but previously I had backed up via TWRP the EFS and MODEM partitions. My phone lost IMEI again , as expected , but after restoring EFS and MODEM , the IMEI was back!!
To sum up , never delete files or partitions that look like "system" like bluetooth and imei folders when you are root AND always have a backup of all your rom via twrp or something else before changing/deleting/flashing anything related to your system.
