Dear All,
I have come across several threads regarding the IMEI null issue and have seen solutions but most of them dont actually work except where Z3 box are used to rewrite the IMEI.
Some threads I have seen that another similar device is required to copy the IMEI from 1 rooted device to another rooted device via FileExplorer, but nobody has mentioned the next step as to how to set the IMEI null device's IMEI back to its original after copying from another device.
Please let me know as I have 2 rooted device both of which are mine.
Both devices are GT-I9505.
Thank You
Appreciate your support.

Hi guys,
i need a stupid nv file for my ks20. yesterday i tried to create a nv backup but the LGMDP_EURO didn't recognize the model of my phone. after than i tried the emergency mode and i clicked the wrong button: it flashed my phone with a brandmarked firmware from vodafone germany.
i found in this board the original unbranded firmware and flashed it on my phone, but i couldn't use it due the "unavailable otp block".
i also read that you have to erase the efs if you have this problem and so i did it.
i lost my imei number, maybe the bt- and wlan-address, too.
do you know a solution for this dilemma?
lol, no one who can help me and the bunch of people with the same problem?
except for the IMEI the other nv options should be the same at every ks20. and this IMEI entry could be replaced with the QPST tools by an invalid one.
why do i find so many crap about "how to ****flash ur bricklocked simphone" but no informations about reconstruction? that's cheap.
but yes: i'm the noob who erased the efs because some bigger noob meant to suggest me to do that...
so plz pm me at least!

Who can help us???

To everyone,
If u need .nv2 file, pm me with ur imei no. and email address, i can generate one for you, but the last digit, which is calculated by your phone, would likely to be different and also i can only generate branded .nv2 since i only got branded .nv2 file. It could be work in unbranded phone but just u need to flash a branded rom or hybrid rom to use with it.
The last digit of IMEI is a checksum, so if the 14 first digit will be correct, then the last one will be correct as well.
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 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...
Hello XDA, I have been a user/fan of xda for about 5 yrs now. But I havent found a single problem that I didnt find the
answer for here on xda, or somewhere else (Google). I have a Computer and Phone repair shop in Ethiopia and I used the
internet and mostly XDA to Unlock Sprint HTCs, Unbrick Galaxy S/ SII/ SIIIs, repair corrupted efs partitions, install
custom roms like CM (on almost every smartphone I come around), fix bootloops of Best devices like Xperia Z, Galaxy SIII,
Sim unlock Moto Droid ...
But I have faced a serious problem and have been trying to solve it for about three months now.
To the real problem
There Are these MTK MT6582 Devices, Mostly Huawei devices (G730, G610, G630) and they are recently getting a major IMEI
failure (IMEI : null). I have tried through the ff methods (that I use for other MTK devices like MT6572, MT6575) With no
luck
1. Maui Meta 3G - It reads the devices in meta mode
- It can read the version (in "Get Version" window)
- I have selected the Nvram database of same baseband
- It fails to write the imei when I click "download to flash" It either replays "Check the load and device versions are the same (ish)" or "Download to flash time out"
2. IMEI & SN Write tool - Doesn't seem to read the device in meta mode.
3. MTK Droid - Rooted the device
- Restored "nvram" from another working phone
- Rewritten the IMEI
- Still the same (IMEI: Null)
4. Reformatted the whole device and installed firmware with "secro" file - Still the same - tried the above methods again, still the same.
Dear XDA Fellows, I am exhausted with these devices and they are keeping coming. So, Please help me solve these problem. Thank You.
P.S - I dont know where to post this, if there is another appropriate thread, lead me.
