Same Problem
Hello, here the same problem
do you find solution?
pls replay me
thanks

I tested everything but without luck.
But you can test it too
check your IMEI *#06#
if you got null, you have to repair your IMEI
flash blank EFS files with ODIN and set correct IMEI with EFS Professional via Qualcom NV tools
if you skilled to test this solution, contact me via talk - [email protected]. I have many extracted modems etc..

SOLUTION?
Anyone?

solved

CWM doesnt back up the modem..you modem would be the same it was before..flash the earlier modem you had working..or try different modems..

i tried all sorts of modem from the modem collection page here on xda
those modems used to work when i had a different rom but still, is there a way maybe to extract the modem from the ZIP file of miui rom ?
i tried searching modem.bin inside the miui zip file but theres none.
if theres no modem.bin file in it then does that means it uses the existing modem ?
if so then il need to revert back to the rom i had before miui ? or just revert to stock rom ?
ive flashed stock rom and still nothing
also, on mobile networks menu i cannot see any networks to choose from
update
i just noticed my sn has been corrupted , its 000000000000
how can flashing a simple modem from CWM cause that ?

I9200 efs folder deleted and IMEI null/null problem !!

i lost efs folder after root my phone and have not any backup,please help me ,how can i restore efs folder ?
wifi ,blutooth and network stopped working.
please help me .:crying:
Anyone want to help me?
I can guess the reason why people don't respond to your problem. The methods available to restore the IMEI are illegal as you can also use them to change the IMEI. My advice is to take your phone for repair.

That sounds great as I was going to mention about flashing the modem by itself..but I was not sure if it would correct the problem or not.

Firmware S3

Hello, i have recently remove a custom ROM and i replaced with an original firmware. Problem is that i don't have backed up EFS folder, and my phone is not connecting to mobile network. I have check the IMEI and is an generic IMEI not original.
How can i find which baseband is good for him?
Flash 4.3 stock firmware, if efs still corrupt then pay for a repair.
I have do that, but is not working .. network mobile can't connect..
Anyone has a solution for this problem?

Try to flash a firmware older than MG4 and start OTA-update. Perhaps this will repair your efs-data.
