Now lets see the tutorial:.
How to restore the NVRAM with Maui META 3G and SP META
Youtube Link here on this post: http://forum.xda-developers.com/unite-2/general/guide-repair-imei-invalid-micromax-t3048984
First 3 basic conditions
1. Make sure that you have really damaged NVRAM (the information is up).
2. Charge the smartphone. I recommend to charge it all the way to 100%.
3. Find and download the factory firmware for SP Flash Tool. There must be a base APBD and MODEMDB (usually in the folder of the same name, but rarely in the bulk folder target_bin). Skip this is you have it allready.
Creating a basic structure of NVRAM settings and recording IMEI.
1. Perform clearing the NVRAM or Formatting telephone (recommended) .
2. Remove and reinsert the battery. If this is not possible, after switching off the machine wait for 1 minute not less.
3. Install the drivers.
4. Flash STOCK Firmware.
5. Disconect the phone from PC.
6. AGAIN: Remove and reinsert the battery. If this is not possible, after switching off the machine wait for 1 minute not less.
7. Now with the phone powered off start with button pressed "Volume Down" and "Power" and keep up till the appearance of the logo. On the screen of your smartphone after the logo should appear on a black background "Have been in meta mode". TURN OFF THE PHONE.
8. WITH THE PHONE POWERED OFF connect to a standard computer "MicroUSB cable." In Device Manager, the equipment will appear: "CDC Serial" and "Lenovo XX". Using drivers SP_Drivers_EXE_v1.6.rar device "CDC Serial" to install the drivers "MediaTek Inc. -> MediaTek PreLoader USB VCOM (Android)", the unit "Lenovo XX" install drivers "Google, Inc. -> Android Composite ADB Interface"
9. Start MAUI META
10. In the menu: Actions - Open NVRAM Database. Select the file (usually begins at BPLGUInfoCustomAppSrcP ...) from my modemdb factory firmware for SP Flash Tool. For example for the A850 + file named BPLGUInfoCustomAppSrcP_MT6592_S00_A850 + _V1_1_wg_n and size 5,5MB for A606 file named LWD3I15.1.6.1.3T21A0828_M015.src and size 7.3Mb. The main thing that this file has been included with the firmware that is now on your phone. It is important!
11. Press Reconnect. Flashes circle from red to green.
12. AGAIN: Remove the battery and re-set. If this is not possible, after switching off the machine wait for 1 minute.
13. Turning off the machine connect to a standard computer "MicroUSB cable."
14. If the program is successfully connected to the phone to change the color of a circle of yellow and opens the selected option. ** Before connecting the program selection option is not available, so if it is not "Update parameter" just close the window that appears.
15. In the main window of the program Maui META 3G select "Update parameter"
16. In the "Update parameter" click "Load from file" and select the ini-file with the calibration. Base to restore NVRAM as possible will be augmented with such files.
17. Click Download to Flash
18. Wait until all the blue lettering turn gray, close the "Update parameter".
19. In the main window of the program Maui META 3G select "IMEI Download"

21. Go to the second tab. Enter in the field without the last of the IMEI numbers (it will be calculated automatically) and click "Download to flash". If you can not find / remember what was the IMEI, then add to the penultimate figure 8, the checksum will be calculated automatically.
22. IMEI Download Close window and click Disconnect. Phone out of METAMODE and power off.
23. Reboot.
Record MAC-addresses of Bluetooth and Wi-Fi, as well as SN in NVRAM.
1. Start SP_META (Attention! The second program from the set). If the proposed version of the program is not connected to the phone, then we try to pick up a different version .
2. Select the option "AP NVRAM Editor".
3. Press Reconnect. Flashes circle from red to green.
4. Remove the battery and re-set. If this is not possible, after switching off the machine wait for 1 minute.
5. Turning off the machine connect to a standard computer "MicroUSB cable."
6. If the program is successfully connected to the phone screen appears "AP Editor".
7. In the "AP Editor" click "read from NVRAM". The program will ask you APDB. Select the file (usually begins at APDB _...) from my apdb factory firmware for SP Flash Tool. For example for the A850 + file named APDB_MT6592_S01_ALPS.JB9.MP_ and size 163Kb for A606 file named APDB_MT6582_S01_KK1.MP3_ and size 162Kb. The main thing that this file has been included with the firmware that is now on your phone. It is important!

I tried to restore mac addr bluetooth and wifi, but no results. Bluetooth addres passed, wifi mac always was wrong (I wrote both them just after buing phone, but unfortunately I didn't make nvram backup) My phone lenovo p780 2014 (speed version). I tried to use many tools (probably all possible). Maybe I have wrong modemdb file? Installed rom is 226 (Kitkat), rooted, twrp. I tried to restore nvram.img (file from web)- no results.
Regards

Thanks for your feedback! Did you tried stock JellyBean firmware?

Yes, but not every tool. I will try to flash 116 rom, i tried already few times with 228 preloader, but something was wrong. I'll try to use different preloader...

I flashed 136 rom (4.2.1)
I tried to restore everything (four in one)
result:
"OK: Connect to target successfully.
>>Step: Start to write Wifi MAC.
Error: Write Wifi MAC fail. Meta Result = META_INVALID_ARGUMENTS"
I don't know correct serial (I bought only mainboard and I forgot to write it down)
Maybe this is a reason?

In stock firmware, in the archive you will find 2 files. That are the files from step 6. Look in what i have posted on the google drive. There are the files.

. In the menu: Actions - Open NVRAM Database. Select the file (usually begins at BPLGUInfoCustomAppSrcP ...) from my modemdb factory firmware for SP Flash Tool. For example for the A850 + file named BPLGUInfoCustomAppSrcP_MT6592_S00_A850 + _V1_1_wg_n and size 5,5MB for A606 file named LWD3I15.1.6.1.3T21A0828_M015.src and size 7.3Mb. The main thing that this file has been included with the firmware that is now on your phone. It is important!
