FOR SURE NEED ROOT
WE HAVE TWO TYPE OF Note 3s:
1- devices with /dev/block/mmcblk0p11 block for EFS Like N9005, Snapdragon
2- devices with /dev/block/mmcblk0p3 block for EFS Like N900, exynos octa
According To This Post, N9005/Qualcomm Devices Need ModemST Blocks For Restoring IMEI! and fsg and backup blocks!
EFS Professional v2+
with Qualcomm device support
Thanks To @lyriquidperfection
i will Change Windows EFS Tool for fsg backup if you need it...
Base Work of Windows EFS Tool is From This Thread Thanks To @A.S._id
you can use SAManager app too (package name for search: com.pyler.samanager)
you can use Samsung Tool V2.0 from this thread too.
Remember: Samsung tool has different Version For N9005 thanks to ricky310711
not working for n9005 because it can't backup fsg...
AROMA EFS Backup/Restore
Thanks To Dr.Ketan For Base Files From this thread
Don't Use Dr ketan's Aroma For Backup N9005. It Won't Work.
Backup efs in CWM (like philz touch) in Custom backup section
you can restore it very easy in Custom Restore section.
i think it won't work for nN9005
(EXAMPLE for EFS BLOCK)
or you can Backup it yourself with adb command to your sdcard:
dd if=/dev/block/mmcblk0p11 of=/sdcard/EFS.img bs=4096
And You can Restore it With THese Commands:
dd if=/sdcard/EFS.img of=/dev/block/mmcblk0p11 bs=4096
dd if=/dev/block/mmcblk0p3 of=/sdcard/EFS.img bs=4096
dd if=/sdcard/EFS.img of=/dev/block/mmcblk0p3 bs=4096
this post is good For FIXING too
