nop, my IMEI is there, but the mac isnt... mac:unavailable
im too i dont have something wrong on my imei and mac addr.. anyone can solve this ???
Try this
Backup your IMEI if it is not null
1. Your phone should be rooted
2. Download and install 5iromtoolbox
3. Open 5iromtoolbox app you installed and look for "backup imei"
App backup your phone's imei.And after that, when your imei nulled, root your phone if it isn't, install that app again and look for "restore imei"
And don't delete any folder named "5irom" or similar.It contains 3 img files.They are important.
Get back to a official GB and check your mac adress, if it's null get back to android 2.2 and take note of your mac adress
Root your phone
install the rom you wan't
check your imei, if it is null install 5iromtoolbox app again and look for "restore imei"
Override MAC Address:
-Install Terminal Emulator from Market.(with data or via PC)
-Run terminal and enter these commands: (where is "11:22:33:44:55:66" you should place your original mac address)
su
setprop persist.sys.wifimac mac_param=11:22:33:44:55:66
Hope it helps

Dear Friends, I have Flashed the latest " A3000_A422_000_006_130517_WW_CALL " Firmware. Now My Tab is Not Showing any IMEI numbers. When i check through *#06# the imei display dialog box Both IMEI Fields showing INVALID IMEI. Also I cannot Make Calls or Send SMS messages when i am in 3G/HSDPA mode. If i try to make a call it will automatically Disconnects right away i dial the number. But if i switch to 2G mode, then it will allow me to call. Then i tried other Lenovo Firmwares also. But still the same IMEI and calling Problems there with the all Firmwares. I think something Badly Happened to My Tab. Please Help me to Fix It. Pictures attached. thanks.

Like bnbhaohao90 said
use imei.exe via cmd
Code:
imei.exe imei_sim1 imei_sim2
replace imei_sim1 and imei_sim2 to your imei
you will get file "MP0B_001_NEW"
rename to "MP0B_001"
then copy it to /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001
then chown and chmod
via adb
Code:
adb.exe shell "su -c 'chmod 660 /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001'"
adb.exe shell "su -c 'chown nvram.nvram /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001'"
OR via terminal
Code:
su
chmod 660 /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001
chown nvram.nvram /data/nvram/md/NVRAM/NVD_IMEI/MP0B_001

I have a new SM-N900
AP:N900ZSUBMI5

MAIN BAND : N900XXUBMI2
BUILT NO : JSS15.JN900OZSUBMI5
KERNEL : 3.4.39-1624790 [email protected] # 1
The problem is it founds network with a ! eclamation on network.Can't get calls or net connection.
All others are working.
when hit *#0011# it says "IMEI : CERTI.FAIL"
i'm not sure if it's a EFS problem.
Is there any solution ?

EFS is signed. if it fails its check it give the same symptoms you have id lean towards efs failure

Can you please explain a bit ? Didn't get it properly...
I tried install a rom with Odin but it failed at setup.img.
Maybe i didn't find the original rom.
A help will be very useful.

The efs contents are signed if the contents change the signature is broken. think of a seal on bottle of drink once opened its no longer "sealed" and the contents may not be what you expect. this either causes bootloop or no network as the phone ignores the details

So my nexus 4 /data/nvram/blahblahblah is gone which means that in turn my imei is also gone. I used this as a reference guide:
- http://hackershandbook.org/forum/hacking-discussion/nexus-5-imei-change
I successfully extracted my friends nvram using QPST. However I cant seem to push the nvram (qcn file) to my phone, every time I try to do so I get this error message:
Exception Thrown!!
NvManager::writeToPhone( const string comPort) - QpstServer::sendSynclmpl - Bad response from phone (DM packet commands 19-24)
Im kind of stuck at this point I also get the error message from nv items reader/writer (after I generate the IMEI file for my phone using nv_gen.exe):
'$-9' is not a valid integer value
So im stuck at this point and phone less. Anyone got anything for me? Thanks in advance!
Note:
- I'm on Cyanogenmod 4.2.2 (4.2.2 only firmware that boots without imei)
- Friend was on stock 4.4.4 when I extracted nvram from their phone
- Any other methods that you guys have that may work for my imei please share, im all ears.
The reason it failed in the first place could be a hardware fault, which means this wouldn't fix it. But the guide you are following is for a samsung s3, I think you might need a box to do the n4.
This guide is for those who have lost their IMEI, have corrupted EFS, or erased EFS partition. So, follow these under your own risk, it may or may not work, and if something happens or doesn't happen, then i am not to blame. So, once again i will not take credit for bricked phones or something along those lines, however i will take full credit if this works for you. I will also provide assistance to those who could not restore their EFS following this guide.
Before proceeding with this guide, backup what you have left. Use twrp to backup and in case something goes wrong and your problem escalates, you can restore using twrp backup.
Restore EFS
Change IMEI Number
Restore EFS
Do this if and only if you believe your EFS is corrupted, or you somehow erased it. If you are not sure about it, then simply follow the next guide to change you IMEI number. In most cases people loose their IMEI only and not the whole partition. Again, it may or may not work, so do this on your risk, and i am not to blame if anything bad happens, but if you do succeed, then don't forget to give me credit.
Note:
If your EFS is erased or corrupted, your IMEI and Baseband will be shown as unknown. In this case recover the EFS following this post, and then change the IMEI following the next post. If your IMEI is shown as 0, then you EFS is safe and most probably your IMEI is gone. In that case, no need to recover EFS, only change the IMEI number following my next post.
In TWRP, backup of kate wont show on kenzo and the backup up kenzo wont show on kate. In case no backup is shown even if you are using the right device, then try the dump flashing method or try changing the TWRP recovery.
Flashing this will only restore your EFS partition, but the IMEI will still be gone, so you will have to follow the next guide to change your IMEI.
Even after flashing a new EFS, you Mac and BT address will not recovery. The android system will assign a software generated address to both devices. Dont worry cause even without the EFS partition there will be a Mac and BT address assigned to your device and both the things will work normally.
If your Baseband is still unknown, even after flashing a new EFS, then try flashing latest radio file. It can be found in any firmware update package, either the official or the one from the strix.
1. Download the required files from the link given below.
EFS Backup[Kenzo] - Contact me if someone has backup of this.
EFS Backup[Kate] - Contact me if someone has backup of this.
2. Extract the Dump Backup files and flash them using the following commands.
Code:
fastboot flash modemst1 modemst1
fastboot flash modemst2 modemst2
3. Now reboot and voila you have you a new EFS partition at your disposal.
Change IMEI Number
Requirements:
Root
USB Debugging is turn on
Windows Driver Signature is turned off
ADB and Fastboot Binary Files
Latest MiFlash Installed for the latest drivers
1. Connect your device to pc and open the adb folder. Then open a command promt window.
Code:
>> [B]Shift + Right Click[/B] anywhere in the adb folder
>> Click on [B]Open Command Window Here[/B]
2. Type the following command to enable Diagnostics mode. Allow debugging if asked.
Code:
adb shell
su
setprop sys.usb.config diag,adb
4. Download the IMEI Changer from the link given below.
IMEI Changer [Credit: Archeolot]
5. Now, open the imei changer, and enter imei number in both the fields. And click on start. After a moment it will show as passed. If it fails make sure that you have followed the points i stated.
Note: Make sure that the driver in driver management under ports is listed as "Qualcom HS-USB Android DIAG 901D" and not as "Marshall London HS-USB Android DIAG 901D". If it is listed in any other name, then go to driver management and update driver. Select browse driver, then let me pick driver from a list. Then select "Qualcom HS-USB Android DIAG 901D" and then finish.

Glad i could help mate. Can you confirm your mac address and bluetooth address, whether it is same or changed.

Can't confirm. My EFS partition was so corrupted from trying other tutorials to restore my IMEI that I didn't even bother backing it up because I thought that it could have been changed already (tried writing to NVRAM with QPST). Since I don't have my original mac and bluetooth addresses written down anywhere (I haven't written them down myself and I don't think they are to be found anywhere on the box or on the phone) I think the only way to check it would be to compare my current addresses on the phone to the addresses contained in your EFS backup. Can you extract them so I can check if they match or not?

The mac address and bluetooth address in the efs are my own. I only changed the imei so that no one else can copy it, i didnt know anyway to change mac address. Besides the mac address doesnt matter that much, and i dont think that we will ever be on the same wifi network.
If you dont know then i can explain, that the mac address is required to maintain switches and broadcast in the router, so it technically does not matter.
You can change it later with some apps or use it like that if you wish, if i find any way to restore you mac i will post it too. In the mean time just post a snapshot of wifi mac and bluetooth address so that i can compare them with my own.
So, using this way, one can change the IMEI no. also?

Yes, just use the imei changer in the rar file to change your imei. But make sure to backup or atleast note down your imei before doing so.

Yup, they are not mine. Mine start with 64:cc and so on for both mac and bluetooth. They may be software generated or may be your own, technically i am not sure.
Edit: did you use imei changer to change imei no. Or are you using the default values. If you are using the default values, pls post them too. If you change them, then give your review, ie was it hard or easy, did you encointer any problem, stuff like that.

After flashing your EFS backup both IMEI values were set to "0". On the default values I don't think the phone would be able to register on any network with the sim inside, but I haven't tried that. Then I flashed my IMEI with the app you provided in the .rar. Set my IMEI same for both slots because I've got only one written down on the box so I think it is set how it should be out of the box. After that I've rebooted to EDL and flashed global developer rom. And it's all working, I'm able to make calls from both sim slots, however didn't try having 2 sims inside.
All in all the process is very easy, definitely the easiest out there. I haven't encountered any problems, however I think others may have a problem with drivers to get "Qualcom HS-USB Android DIAG 901D" working. Mine was working already because I tried this tutorial before. Thank you for this guide, and providing your backup

Guys. I messed up my phone by restoring a nandroid backup from a different one.
I was able to restore my IMEI using some qualcomm tools. My problem now is that fingerprint scanner won't work on any rom, even official.
Any idea what else I have messed Up? I don't think restoring this efs will fix my fingerprint scanner. Is fingerprint scanner info in a different partition?

Have you checked with miui7 stock rom. As far as i know there are three sensor modules for fingerprint, on of them is goodfix which is currently not supported by many roms. If your is goodfix then it will not be supported too. You can flash miui rom to check whether the fingerprint works or not...
If it doesnot work, then try to resotre your nandroid backup agaian. This tym simply untick efs.
