Hey All ... i am having galaxy s4 i9505 ... i downgraded my s4 from 5.0.1 to 4.4.2 and efs is curropt now ... i again flashed lollipop stock firmware but still imei is null and baseband version is unknown ... i tried many methods but always failed .. i dont have any efs backup and i mistakenly cleared my efs using a tool ... plz help me out what should i do ....
First, backup your efs folder to as many places as you can. Also backup efs partition with philz recovery.
Then flash cm12.1. Now delete efs folder from your new cm12.1 ROM. Copy and paste the backed up efs folder to the same place where you deleted the old one. You will get network and imei in a few seconds.
Once you get network you can now flash back stock 5.0.2 via Odin or stay happy on cm12.1

You flashed via Odin using original Samsung USB cable?

How can you mistakenly clear your efs using a tool? All you had to do was flash the correct modem. What is your current modem?

Not sure what else to suggest unless a cell shop is able to create and flash the efs.

Backup EFS first, then flash a stock ROM from sammobile.com.

I Installed Stock rom And restore EFS Backup but No IMEI
Did you have an IMEI to start with ??
I Started with basic IMEI from Custom 6.0.1
What does basic IMEI mean .
IMEI is tied to your phone .
I mean i don't change IMEI
I made backup for EFS On custom 6.0.1
and after install Stock 5.0 And restore EFS Backup....... IMEI still NULL

IMEI Null After Stock Rom
So after flashing the Renovate ICE r135 my IMEI and baseband show up as Unknown in settings, which means that I have no service. I have looked online and seen the use of combination files, although I don't see any for the Oreo update (only 7.0 files). Are there any combination files for 8.0 or alternative solutions to restore my IMEI number?
Last time I checked, if you lost your EFS file (IMEI no.) thats it your done.
You shouldve backed up your EFS. If you lose your IMEI you need to restore your EFS otherwise your phone is finished.
@hs102
befor you flash Renovate ICE r135 da you make one backup with TWRP of your "old" Rom?

Yes, I flashed the stock firmware with ODIN but EFS is lost and now no baseband or IMEI. Wifi and Bluetooth are working.
Any Chance?
Look for correct firmware. Using csc code and build number. Happend to me. Solved it

It happened to me few weeks back. I tried flashing indian firmware on my uk region s8. I lost imei and baseband. Then i looked for csc code in download mode. And searched on sammobile. Search using csc code. Then you'll find few firmwares. March your build number and download the correct firmware. Use latest odin and dont use home csc file. Use the other one. This will solve your problem.
Hy guys!

Just reflash firmware via twrp ?
Backup efs and flash rom if you lost imei then restore efs backup .
I haven't faced this issue but I think this method should work
Edit
also this is the the place to ask for help go to s8 questions and answers thread

This happens only on custom roms. What ever custom rom i flash i loose imei , when restore to stock everything works. And the efs backup doesnt work
manually flash latest firmware ( bootloader and modem) . then try flashing rom again.
Note
Flashing bootloader removes recovery you need to reflash recovery again
