How To Backup EFS Folder ? (IMEI)

[M1cha]

no u have to enter "su" before you backup the partitions, but since this was written in the original post I think u did that.
And even without permission he should show "Permission denied" and not "File not found".

Can you post the output of this command?

ls -l /dev/block/platform/msm_sdcc.1/by-name/

that means that the command ls is not found not that the folder is not found.
try this:

busybox ls -l /dev/block/platform/msm_sdcc.1/by-name/

When I do it in portrait mode its fail...but when I do it in land scrap mode its work

If want to restore the efs file what is the code for it?

My friend Mi2S cant connect to wifi, but in the phone status the IMEI number still can see.
If I check path /dev/block/platform/msm_sdcc.1/by-name/m9kefs* dun have those 3 files mean the EFS had spoil?
