Hey guys,
I'll put it as simple as I can :
-no SIM service whatsoever. Happened a few hours after i flashed Androidmeda ROM. no clue if thats the reason
I tried:
- restart
- wiping all caches and data
- factory reset ( 3 different ways )
- flashed 3 other ROM's
- recovered a very old nandroid backup i found
- drained the battery, recharged fully
- left battery out for a few hours
- slapped it around (gently)
Im drained out of ideas. Any clues? anyone?
Thanks in advance
Sim card in slot .
Check you have the correct network settings .
Check IMEI is the original one .
Wrong IMEI restore your backed up EFS folder .

is rule one backup efs folder so you can restore your IMEI ..
The /efs folderThe /efs folder is a folder in your phone that contains information specific to YOUR phone, for example your IMEI number, product number, Wireless MAC addresses, and much more. There have been reports of people messing up their /efs folder when unlocking their phone or flashing new ROMs, here is an example from the Nexus S development forum (jump to page 111 to see everyone start to panic):
http://forum.xda-developers.com/show....php?t=1034130
Therefore, it is important to make a backup! Instead of just regurgitating guides on the forums already, here is a link to a very good one by Rawat:
http://forum.xda-developers.com/show....php?t=1068193 (Rawat)
The easiest way of doing it is by using terminal emulator rather then ADB (unless you have ADB all up and running and are confident with it)
You need to search the other multitude of IMEI posts see if you can find a fix .
If not its a service centre repair if you have proof of ownership and no custom rom and no root and custom rom counter set to zero .

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

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.
WOW.. Thanks mate..
It's gonna very Helpful for me & other ppl.. ??

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.

Current addresses on my phone:
MAC - 00:0a:f5:a9:XX:XX
Bluetooth - 7C:7F:F0:82:XX:XX
Left out some numbers just in case they are mine. For the purpose of checking that will still be enough

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.
This is the dual sim model, in settings about device, If I try to check IMEI it just says unknown so my guess is the EFS partition got cleared (if it exists on nokia devices?). Anyone have any experience on repairing the IMEI on this device?

You are right. Actually, I dont have much to lose anyways as the phone is becoming replacement parts if I can't repair it. I will sent the imei via pm. Also, not sure if qcn restore if even enough, there is a chance of broken efs as well.

Hi
Hello everyone I am so sad. Because A few days ago I noticed that the baseband was unknown. IMEI 1 and 2 unknown and Android ID Null from my Asus rog phone 2 Zs660kl version I001DC Global version and I cannot do anything because there is no any Qcn file for this phone , I am unable to do anything in my own, I do not live in United states, I cannot send it to repair, it would cost me the tax again, like 147 dollars again that I paid for the customs. Please if anyone has a good hearth to back up the Asus rog phone 2 file from the same version with the qpst toll... I would really appreciate. I need it , I tried to find the IMEI with Hxd editor and there is not any 1111 to find the error so I am unable to to that. There is no any Qcn file. I need a Qcn file from the same phone with a phone that has the baseband and the rest fine".
I need to have the Qcn file from this same phone I have issues with the baseband IMEI unknown and Android id Null, by doing this you can help through diag mode you just follow this just download Adb minimal, open it and and write Adb devices, then Adb shell then Su and finally setprop sys.usb.config rndis,diag,Adb enter and in device manager you will see in ports, Qualcomm devices which you can continue doing the next step which is installing latest drivers from Qualcomm on this video you can follow the steps After installing the latest qualcomm driver, the qpst tool will recognize your phone because it is now on diag mode since you did the previous step, by checking this video you can back up the Qcn file which is what many people need and there is no other way to solve the issue only with a phone which is in perfect condition as yours
how to use the qpst tool to backup the Qcn file , First diag mode with the commands I gave you second is installing the latest qualcomm drivers then backup and restore Qcn , and then you will have it done,
download the qpst tool and the Qualcomm drivers and it is an example of my problem with the baseband, you can guide with the one video and the third , the one video do not use the commands given by the YouTuber, because that do not works, use the commands I gave you , that works for our phones, and then the third video is explaining how to backup the Qcn file which contains the data? I was unable to edit myself the Qcn data from my damaged phone cause the IMEI is not there, there is no any 11111 number to replace it for my own IMEI, sadly,... Just need the Qcn from a good phone, please!!l
If anybody is still offering to do this and can help me... My phone is hard bricked and I can't do anything... I feel I can fix it with a QCN... Anyone want to help?
