N7100 EFS Backup / Restore

Hi,

Just ODIN recovery & root... driver updated as per Dr. Ketan
Windows 7
N7100 - Middle East edition with firmware XXALIH
Settings enable for USB debugging
SU works normally

BAT file stop at waiting for device...

Any manual procedure as I s\did not see any file in /dev/block/mmcblk0p3 using "root explorer"?
Why we need t back-up EFS again?

Run "android Commander" and device not found. Should I re-install driver as per Dr. Ketan?

Thanks...

Back-up NAND using CWM compare back-up EFS?

Hi, excuse me. Whats the different back-up NAND using CWM compare back-up EFS?? Which better? Which more important? I'm sorry my english is not perfect. I'm just noob newbie(beginner). Thanks very much. Appreciate.

 

[luba6ky]

They both are important!

 

[xplus93]

The nand is usually what holds your rom and data. Your EFS however usually hold programing information such as IMEI or MEID and on cdma phones tower information and 3g keys and authentication information, basically whats on a GSM sim.

Save EFS on Mac Os

Hi,

I managed to modify a bit your Linux version and run it under Mac OS Lion
Here is the package in any case you want to add it to the OP.

I changed the adb binary, and removed some commands which weren't running well on Mac

Please note I did not test the restore function, but due to the very little modifications, it should work as well as the backup

 

[kastafela]

Fantastic
