My imei no got lost while restoring backup using cwm..... i looked around the forum and the ".nv_data" method will not do because my efs folder has a file named "essiv" only and nothing else.....
if someone would confirm what files are contained in thier efs folder and mail it to me also i'll be grateful......
I don't think the 'efs folder' of one device can be used with other devices as it contains the device's IMEI number.
Could you elaborate a bit as to what did you do that resulted in the loss of your IMEI number ? It would help others avoid it in future.
Well.... i restored the same backup file couple of times 'coz i was trying to flash a new theme...btw i am on stock indian 2.3.5......
the files in efs folder can be edited using hex editor (read somewhere in the s2 forum...i don't remeber which thread) so the imei no. in that file can be modified...
Hi I had the big problem with touchscreen after upgrading firmware. The halfs are swapped.
When I tried to repair it, I destroyed the whole nvram. Can anybody send me the working NVRAM image or create ini file from MAUI META?
I will change IMEI, WIFI a BT , SN or you can delete from INI file.

Hi, Everyone
I am new to flashing of MTK based phones and found that they are relatively tough to flash for an amateur to start on for a beginner. I had fortunately taken a incomplete backup of my phone which is why I was unable to solve majority of the simple problems that I am currently facing. I saw that, MTK Droid Tools can be used to restore the NVRAM from a backup to restore the previous IMEI, Bluetooth address, WIFI address, GPS address but the software was asking for a .bin or .tar file and unfortunately I didn't know about NVRAM until now and I don't have the .bin nor the .tar file but what I currently have now is data.ext4.tar from my stock rom which has a folder called "nvram", I was thinking of manually replacing the folder I have with the folder in the root but I need a better solution than that. How can I convert or pack that folder as a .tar or a .bin file?

Hey guys,
Does anybody have a qcn back-up file for the MI 4 LTE-CU?
I need it very bad. I flashed wrong modem firmware and now my nvram (12, 13, 16th partition) is corrupted . I have no IMEI, baseband and cellular info.
Hope someone can help me.

Try Qualcomm IMEI Writer or QPST tools.
I tried them both but I need a qcn file complete. I do not know how to write a complete qcn file myself.
If I can get a similar qcn file from the same device I can change the IMEI into my own using QPST and a heximal IMEI converter.

Is it the LTE FDD version of MI4? I tried to flash it using QPST but no success so far.
It can not reset NVram it says. Complaining about incompatible model number.
Thanks for your help! I going to examine the file later this week and then give it another try. Probably coming weekend.

It works!! Finally I got it. I used XVI32 writer to change the IMEI in the above qcn file. With Qfil I was able to restore the adopted qcn file.
Many thanks for sharing, Yingice!!
Solved!
I've already posted a problem I'm facing with deleted EFS partition in this post: https://forum.xda-developers.com/mi-mix-3/help/efs-deleted-imei-signal-bootloader-t4149381
Now I'm in need of a QCN file to restore my IMEI & baseband which I can't find anywhere on the open internet. So, it would be great if someone could please share their QCN file for Mi MIX3 (perseus).
Thanks in advance.
Here's a guide on how to backup QCN:
