This is probably the most effective way to get IMEI back without losing any data, etc.
Let’s start now….
1. At first download Root Explorer from Play and Zarchiver apk
Download the imei fix  Cwm ImEI Fix
2. Now open Root explorer goto data and you find a folder name ‘NVRAM’ copy it to your memory card..
3. Now the other zip file you downloaded, extract it (By 7zip-PC) (By MiFileExplorer/ES File/any thing else-Android)
4. Now delete the NVRAM folder from the extracted zip file (data>NVRAM)
5. Now copy the NVRAM folder which you copied earlier by Root Explorer and paste it on the extracted zip file (data>NVRAM)
6. Now rezip the extracted files & flash it through Philz recovery without wiping anything… You will get your IMEI back, 100% working worked for me too….

    I wasn't backup my imei nor stock rom please help me i will appreciate you're help

    • I flashed stock firmware and I've still no NVRAM folder. How can I get a NVRAM folder of an other sm-g920F? And if I replace the IMEI number in it with my old IMEI, Will it works?
      Do you know if Samsung Support can restore my phone? Including a new NVRAM folder with maybe a new IMEI or can they inject my old IMEI?
      After 3 days of searching, You're the only one who can help me… Thanks

    • Go to Xda developers website and look for someone that use same device to help you with the file or take to guys that repair phone in your hood to help you fix it they will use a flash Box to fix that…
