i searched for this but don't think that anyone has posted this method here before (if anyone has posted this method here before then i am really sorry for the Repost)

by using this method you can backup your IMEI/NVRAM and Restore it!!!!!!


if you are facing the "invalid/no IMEI" issue or the "NVRAM error" then you can solve it by using this method!

Do you guy's have a cwm/twrp backup of your original ROM? (the one where everything was fine!!)

if yes , then you can resolve this imei/nvram/wifi_mac issue!!!

you'll need to download MTKDroidTools_v2.4.8 then extract it!!

for taking Backup of your original "IMEI/NVRAM" , just follow these steps:-
1. restore your original ROM's CWM/TWRP backup. (If your ROM is not Rooted, then Root it)
2. Run "MTKdroidTools.exe" from the extracted folder.
3. connect your phone to PC/Laptop through usb cable (no need to switch off your phone, just make sure that "USB Debugging" is enabled)
note:- After connecting your phone the program will display Info of your phone.
4. Click on "root" button at the bottom of that program window. (this gives adb shell access for the program to your phone)
5. Click on the "IMEI/NVRAM" button.
note:- It will open a pop-up window
6. Then click on "Backup" button in that pop-up window. (This will backup your original IMEI and NVRAM )
note:- the backup will be stored in the "BackupNVRAM" folder in the "MTKdroidTools" folder.

now you have the backup of your original IMEI/NVRAM!!!!!!!!!!!!

now flash any ROM that you want to, and after flashing it, if it still gives you the IMEI/NVRAM error just restore the backup that you've just taken

steps to restore the IMEI/NVRAM :-
1. Run MTKdroidTools.exe
2. connect your phone to PC/Laptop through usb cable (no need to switch off your phone, just make sure that "USB Debugging" is enabled)
note:- After connecting your phone the program will display Info of your phone.
3. Click on "root" button at the bottom of that program window. (this gives adb shell access for the program to your phone)
4. Click on the "IMEI/NVRAM" button.
note:- It will open a pop-up window
5. Then click on "Restore" button in that pop-up window.
note:- it will ask for two files (a ".bin" and ".tar" file) ,select the correct files from the "BackupNVRAM" folder.
6. There you go, now your original IMEI/NVRAM has been restored!!!!!!!!!!!!
not sure if you need to restart your phone or not , but i recommend that you restart your phone!!!

I followed the guide to restore the original NVRAM/Bin but it still shows no baseband or IMEI upon restoring. What did I do wrong?

Hi Ravi,

one is not turning ON and also not detected by computer which is on pure stock not even rooted.
second one is CM11 v0.19 but no GSM signal struggling from last one and half month to restore nothing worked. even after setting the GSM parameter.

If you have found the solution please let me know.

Thanks,
Shiv
