There is no /efs folder on Xiaomi devices like for example Samsung devices.
I haven't seen backup methods yet.

If you update using the updater app/OTA you don't have to worry about IMEI

But if flash with ClockworkMod Recovery
flashing ROM's Will it be safe ?

dd if=/dev/block/platform/msm_sdcc.1/by-name/m9kefs1 of=/sdcard/m9kefs1.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/m9kefs2 of=/sdcard/m9kefs2.img
dd if=/dev/block/platform/msm_sdcc.1/by-name/m9kefs3 of=/sdcard/m9kefs3.img

open Terminal emulator or adb shell and enter davfiala's commands.
After that u'll find the backups on your virtual sdcard. You should copy them to your pc because the virtual sdcard isn't a safe place

Copy and paste only one row, one by one. And yes, this is backup of IMEI !?

Restoring is same but reversed:

su
dd if=/sdcard/m9kefs1.img of=/dev/block/platform/msm_sdcc.1/by-name/m9kefs1
dd if=/sdcard/m9kefs2.img of=/dev/block/platform/msm_sdcc.1/by-name/m9kefs2
dd if=/sdcard/m9kefs3.img of=/dev/block/platform/msm_sdcc.1/by-name/m9kefs3

Check this path /dev/block/platform/msm_sdcc.1/by-name/m9kefs*
It must be present in phone or you have fake.

I can see those files with root explorer...can I just direct copy those files out?

 

[davfiala]

No, you have to copy it out with dd command. Try it again, but now without typos
