That would mean you lost your EFS. Unless you backed it up theres not getting it back.

so it can't be restore.. i thought there is a way to restore it without efs.. thx anyway
you would have had to make a backup of your original rom. you can always try un-rooting then do an ota update then root again. Just giving some suggestions

So now we have another Nexus S bites the dust !!
Hello!
Am using Samsung Galaxy S i9003 running on android 2.3.6
My phone is not fetching any cellular signal even though sim card is inserted in it. It is asking me to insert sim card when I check for mobile networks. After a thorough check up what I found is the IMEI number is missing. It is showing blank pop up when I check in for IMEI (*#06#).
Also what I've found is:
PDA: I9003XXKPQ
PHONE: Unknown
CSC: I9003SERKPQ.
So I thought this cellular signal problem could be due to missing "phone" file in the software of the operating system. So I flashed a custom ROM (Jelly Bam). I was successful in flashing but am still facing the same problem. No IMEI and "PHONE"
I flashed it back to official stock ROM and I still see the same. No IMEI and versions as:
PDA: I9003XXKPQ
PHONE: Unknown
CSC: I9003SERKPQ.
NOTE : I Have flashed the Stock ROM finally with ODIN with all the four files by appropriately selecting them.
Is this happening due to software error or is this a hardware problem?
Why the IMEI number is missing?
Please help me.

the data present in your efs folder which includes files like "nav_data.bak" "nv_data.bin" they assign IMEI number to your phone... these files might be missing or corrupted... better try any previous restore to fix this problem
Tried that!

I guess you are correct but the restored file on the sd card is corrupted one, I guess. Because the same problem occurred after restoring the previous backups. Can I get any custom restores online for efs? I don't want any warranty for my mobile, I just need it working. In case if it works on a fake IMEI by flashing a custom EFS it is fine with me.

you are on froyo right?? if yes then you simply flash another stock rom of base froyo or gingerbread through ODIN and this should restore your IMEI

No. Am on gingerbread. I've tried Jelly Bam though. But it is of no use. So I reverted back to gingerbread official ROM.

hmmm... actually stepping up for some custom roms based on CM 9 and above solve the IMEI problem.... I recommend you to first download a stock gingerbread ROM and flash it via ODIN... if it doesnt work then download a CM9 based ROM (4.0.4) wipe data/cache/dalvik/ and flash it via CWM recovery then wipe cache/dalvik... it should work and there is like 30% chance to get your IMEI back
But my main point is how u lost ur IMEI suddenly?? You must have flashed something which lead to missing IMEI.
Will Try this once!

No. Once I gave it to my friend. He came up with this issue. He has no knowledge about all these. He said it just lost signal and stopped working!

IMEI is lost when you delete/edit efs data or when you flash a firmware ,but the chances of loss of IMEI are during firmware flashing are very slim

dont worry you still have a couple of options left but to try them you should be calm so that you dont further mess with your efs data.
try thisLink 1
and if you still fail try this Link 2
I hope you recover your IMEI.GoodLuck
trying my luck here again..
hey guys, i've downgraded from CM11S 38R to 25R, but i don't have signal...
it's doesn't recognize my cellular network and yes the sim is in the right direction because i didn't had signal only after i've downgraded.
any suggestions?
heard it has something to do with modem.. tried to flash 44S modem/33R modem and nothing
Why don't you try flashing the whole 44s rom? or try calkulin's 44S?

firstly try to flash u stock rom image using fastboot flash method if it not worked then go to below steps
Have u checked u r IMEI is it ok? If no u have messed up with efs partation and there will be no IMEI so no network no signal
X Have u using custom recovery? If yes have u backed up u r efs partation before downgrading
There are Custom TWRP that have options to back up efs partation
If u have backup with efs then restore it all will be fine
If u don't have backup then there will be lots of problem

Download the stock firmware from updato.com.
Efs will not be included as that is device specific.

hey..
i need to repair efs on the device.. it gives cpefs error on recovery..if i find the nandroid backup maybe i can fix it..
I accidentally flashed Batmen rom and now my imei and baseband is gone. Though , I have efs.img file not sure what software/method I used to make that backup. So, how do I make it work again? does restoring stock rom using odin resolve the issue or how do I restore that efs.img ?

Hey there, flashing stock will restore but if you want to flash the efs image you need to install TWRP.

Somehow solved the issue, by flashing stock from using Odin. But, then, it ran in to issue, showing dead android icon. after that flashed TWRP using Odin and flashed "no-verity-opt-encrypt". No, it's working with the correct ime but incorrect s/n.

You need to edit "serial_no" according to yours(create a new file without extension if you don't have one)
