Need NVRAM.IMG for lenovo s820

Hi,
I have made a mistake trying to change a rom for my device (Lenovo s820).
I thought my phone was gone, but step by step I was able to bring it back to life.
Now I have a working rom and I set back the IMEI's, but I still have "no service".
After reading a lot, I understand that I need to recover my "NVRAM" and to do so, I need for somebody to send my a file called "NVRAM.IMG" which applies to my device.
I can't find this file anywhere on the net.
Can somebody please send me?
Thanks in advance

'"code in Engineering mode:-"'
Just enter this code in dialler:- *#7465625# or * # * # 3646633 # * # *
Now Tap on Call pad or connectivity option or you have to slide the screen.
Just Look for CDS information (Common data service information) option.
You will see Radio information there and after tapping on it.
If you have dual SIM ANDROID then you will see TWO option select any one on which you want to write IMEI with.
Now you will have to put your IMEI no in this manner :- “AT +EGMR=1,7,"IMEI_1” and “AT +EGMR=1,10,"IMEI_2” (replace IMEI_1 and IMEI_2 with your IMEI no) and tap on send command button.
for Example :- “AT =EGMR=1,7”9100XXXXXXXXXXXX”"''

nvram\APCFG\APRDEB\wifi from it i copied wifi name document from my friend tab that is same to me and paste it into my tab data\nvram\APCFG\APRDEB\wifi. my tab wifi doc replaced . the NVRAM ERROR=XO1 from wifi gone...
the thing that i need is that when i restore to default after some days to check there were no IMEI . it says invalid IMEI and also the same NVRAMERROR. that i fixed it again by the above method that i explained. then i do firmware upgrade but this time i did not select the format option, i just download.but after finishing firmware upgrade, when i turn on my tab it says INVALID IMEI AND SAME WIFI problem NVRAM ERROR.

[Q]need help INVALID IMEI AND NVRAMERROR

After JTAG, SIM Card Not Found!

Hey Guys..
So I have a LG - P698 (Optimus Link/Net Dual)
I had a custom ROM in it.. It was going well but then I saw that battery drains much faster in custom ROM.. so I tried reverting back to stock by using KDZ method.. I followed this guide : http://androidforums.com/threads/guide-flash-stock-rom-recover-bricked-lg-optimus-net-p690.852823/
But due to some error.. I can't recall it.. the phone got hard-bricked.. it didn't boot nor did go to emergency mode..
I gave it to a friend who had a RIFF JTAG Box.. and he fixed the boot and flashed again with the above link.. this time it flashed..
But thing is that after flashing, the network never came up.. It showed no SIM Card.. but the SIM was inserted.. I tried the SIM on my old HTC Gene and it worked.. But on the LG it showed No SIM Card..
The strange thing is that SIM Toolkit shows up in the menu and when I open it, it shows BSNL Portal(The Portal for BSNL in India)..
So I think that it detects the SIM.. but fails to contact the provider..
So what can I do?
Thanks in advance and sorry for the long post..

Hello my friend so probability you didn't back up the file where's is the ESN of your phone. So you need to write again. You need to fist this app:

1) Firstly write the ESN of your phone.
2) To do a note in the notes block from your PC with the next:
echo 'AT+EGMR=1,7,"IMEI_1"' >/dev/pttycmd1
echo 'AT+EGMR=1,10,"IMEI_2"' >/dev/pttycmd1
In "IMEI 1" YOU WRITE YOUR ESN. YOU DON'T ERASE THE quotes just erase the word IMEI 1.
(3) the file that you created (can give you the)
name you want) have fun with the memory of your
Android or a Micro SD, the joke is that the
Open in your device.
(4) low the ANDROID TERMINAL application
EMULATOR is totally free in playstore gone
(5) now opens your text file and copy the
first line from echo to cmd1, for that
just select the line and with the radio button
Please COPY or copy
6) on ANDROID TERMINAL EMULATOR, once
you open the app hits the line you copied and
push enter (on the digital keypad, just copy the)
text, no matter that there is a little character
in the application).
(7) repeat the process with the second line.
(8) restart your device with the SIMS
inside (if before the tapeworms in device not you)
worry doesn't pass anything)
(9) ready and are your IMEI restored! Now already
You can use your lines without problem!
As you can see! in less than 10 steps and less than 5
minutes are going to retrieve your IMEI, is very
simple and don't need much knowledge, more
that the copy and paste text.

Okay.. thanks for showing me that it is because of the IMEI..
Can someone else explain it in an understandable English?
and for LG P698.. No offence though..
Thanks BRO!

Sorry, I view that I 've written very bad. So I said that probably your ESN is erased and if you want to get it you need to have this application
Send from my RCA TAB 7" RCT6378W2
---------- Post added at 05:56 ---------- Previous post was at 05:49 ----------
The apps is called android terminal emulator. I don't offence, cuz I learn for my mistakes to write englhis better.
Many times when you upgrade a new ROM, the folder where is the files of the ESN be erase accidentally.

tools here

I would suggest to install Xposed and you can find IMEI changer in the download section. This will change only one IMEI number though. I mean IMEI1=IMEI2.
Another option is to use DFS tools.
And a 3rd option is to use Xiaomi (or similar for dual SIM) IMEI changer, you can use it to change both IMEI numbers.
All can be done provided that you have the box that the phone was packed in with the IMEI numbers on it.

Go to the section Guides where you have posted in a topic with "unlock bands..." There you have all what you need in the OP. Connect your phone in DFS tool, check the section where you have IMEI and update it.
Or use what I wrote with Xposed and IMEI changer.
PLEASE DO NOT CREATE ANY MORE THREADS!!!

sir i downloaded i triedwrite imei but its only sim 1 imei apearing
sim2 showing unknown

Search for "WriteDualIMEI(W+G_eMMC).exe" file. Once you found it, check instructions on google to change the IMEI. It is working for Xiaomi devices as far as I remember. I tried on LeMax2 and it worked. I said I'll do a guide but time did not allow and also I forgot later on. For sure you can find instructions on xda as well.
This is the only tool I found to change both IMEIs.
Good luck!

I'll write down the instructions for you.
1. Phone should be rooted, adb drivers installed
2. Connect the phone to PC and select MTP and USB debugging
3. Open command prompt from Start. In Run, type cmd.exe
4. Type in the command prompt the following: adb shell
5. Then it should show [email protected]_x2:
6. Then type: su
7. Grant access on the phone
8. Then it should show [email protected]_x2:/ #
9. Type: setprop sys.usb.config diag,adb
10. The phone will go to Diag mode, check in device manager if it's like this. It should show at section Ports: Qualcomm HS-USB Android DIAG 901D (COM6). "6" is an example.
11. Open the WriteDualIMEI app and you should see in COM: COM6. This means that device is connected and you can type in the IMEIs.
12. Press START and that's it.
