I have i8262 model. Root Explorer shows no files and folders under efs folder but dialing *#06# shows my imei. I cannot even mount my efs folder in recovery. (says failed to mount error) My phone shows an overlay of "Update Device Information"
I think my efs partition got corrupted but somehow imei is shown.
So, How can I backup my imei and restore efs partition?
Shall I just format it?
Hi I've got a problem.
Times ago i updated to another rom and i missed the efs folder.
I can't flash anything without a efs folder.
i tryed to follow guides on internet to make a efs folder via adb, but without success.
Can some share to me a EFS s7 IMG file, to flash it via Heimdall or Odin?
No, you can't share EFS images, they contain the phones unique IMEI, radios and so forth
Try flashing stock, but if you not backed up EFS and wiped everything, you might need to take it for repair
When we are on stock OOS (before unlocking the bootloader also) with no root or any modifications. Then the EFS partition is completely untouched.
Whenever we are flashing anything a mod a rom or whatever some zips can damage the efs partition. Even though it has only happened to me on a Samsung device before never in a OP device. I'm still wondering if after we have flashed things is the Efs partition still untouched?
So if I made a backup of it after flashing a ROM is it the exact same EFS as when I was on STOCK OOS?
The EFS contains the modem and IMEI, the backup will be the same as long as you haven't modified the EFS.

Okey thanks The EFS and modem partitions have different very sizes. So the efs can't contain the modem or am I wrong? There is Bluetooth, dsp and modem files inside the modem backup folder and only efs files in efs backup folder.
I lost the funcionality Phone in my N8000. I think i lost the imei e someone more else. How can i restore my efs? I have a backup of my efs in format zip and format tar made 5 years ago ( i dont remember what application i used) , but i can not install via Odin or via Twrp, said Invalid Zip format on checking Digest File. I think the problem is checking the md5 generation that is not compatible with Odin and Twrp.
Someone can help me to restore the /efs partition with old backup. Thanks
see your identical post .
I resolved this situation, using Solid Explorer and Qute Terminal with root.

It is not solved, when reboot the system, the imei of phone, N8000 is another, is from another file from i used to recover.
Manually from my backup what files and permissions i have to copy to the /efs in root of my N8000? First i copy nv_data.bin, nv_data.bin.md5 and the folder /imei and works. I do not known the original permissions of the files, perhaps now the problem is this.
Someone can help me?
Thanks
With this guide "[GUIDE] Recover your IMEI in 9 steps. " https://forum.xda-developers.com/galaxy-s2/general/guide-recover-imei-9-steps-t1264021 , i resolved my problem with imei, no problems with reboot, but now i did not have access to Wifi, i can not connect to my Wifi Network.
Someone can help me, how can activate wifi? What files i need to copy from my backup? Before clean the /efs i made a backup the old efs.
Thanks
