hello

Perform a search on EFS, EFS backup and restore on S4, and how to restore if you have the EFS backup already. If not, I guess service center is the proper way to go.

EFS lost on 5.0.1 on 910C

Hello everyone.
Got stock 910C with 5.0.1, today made root and twrp. backed up EFS with terminal emulator (got efs.img) on my sdcard.
Also made EFS backup with twrp.
Flashed custom 5.0.1 rom, right on welcome screen - lots of FCs. Wipes didnt help.
Returned back to backup of stock rom but now EFS got erased. no IMEI and cellular network.
Tried restoring with terminal and twrp - no luck
Can someone advise?
Try to make a software repair with Kies and report back
Dont forget, EFS doesnt contain any IMEI certs or CAL data, so if u clear EFS partition IMEI willl be the same, only SerialNumber will be wiped

can u clarify please. how can be serial number be wiped?
EFS partition -> SerialNo, Bluetooth, WiFi and password + settings
IMEI certs -> SIM LOCK, Imei number. CAL data
As u can see EFS erasing will never destroy imei number

then why did i lose baseband?
When you tried to backup EFS or root you lost MD5 signature of IMEI parititon. Now its gone. In some cases it can be undone by flashing to STOCK firmware.
Please check the screenshot for correct location of EFS partition and M9K partitions
i did restore my EFS by reinstalling stock 5.0.1 with odin.

Flash a lollipop modem and your imei is back.

If you did a backup then you should be able to restore that backup using the same method. Eg: If you used an app, that app should be able to restore the efs folder.
The problem with the EFS folder on the latest versions of Android is that it doesn't contain the IMEI, last time I checked. The IMEI is now stored in hidden partitions, which is why when it comes to backing up this important stuff I recommend Wanam's EFS Backup tool from the Play Store. Not only does it back up the EFS folder, but also backs up those hidden partitions as well as the modem..
In this instance however, Lennyz1988 I believe has the right answer.

IMEI and Baseband Unknown AT&T Samsung Galaxy S5

I updated my SM-G900A to the latest Marshmallow 6.0.1 using ODIN. Afterwards I can't make calls and I have no bars on the top. I may have chosen the wrong settings in ODIN 3.12.3. If my EFS data has been lost can I restore from the EFS partition? I don't think I chose the EFS clear option. I unable to root on this phone right? I am new to smartphones so I'm not sure what to do. Are there methods of restoring the EFS data from the EFS partition if it is still there without rooting the phone? I do have firmware for Lollipop 5.1.1 if that helps.
you cannot recover efs without a backup previous made

So if I used the default settings on ODIN and upgraded to Marshmallow the EFS partition would not be there anymore? What if the EFS data gets corrupted. Is there is no way to restore? I'm just assuming it is the EFS data and not something else. I read the EFS partition cannot be accessed without rooting the phone?
