Hi,

Just ODIN recovery & root... driver updated as per Dr. Ketan

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?

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

    What is EFS, Why it is necessary to backup

    Click below to find answer

    Backup/Restore EFS data of Samsung GN2, to Fix IMEI and SIM not detecting issues

    What the hell is this EFS ?
    EFS partition is actually a internal place in our android device such as android phone which contains some important and some basic info related to our device identity like Wi-Fi address, Bluetooth MAC address and the very main IMEI address (nv_data.bin).

    Now if this EFS partition accidently corrupted then your phone’s IMEI no. will erased and you can not make voice call further. This kind of damage is often not accepted by the service center of your respected handset’s company.

    Why should I backup EFS data ?
    As said above if any case you corrupt EFS then EFS backup can be savior for you.
    So it is very necessary to make a backup of this EFS partition just now to avoid such type of future troubles.

    Now the question is “how to make a backup of EFS partition”.

    There are three methods to make a backup of this EFS partition.

    1st : OP is best tool to make backup/restore of EFS for Note2 Thanx to as i9100.

    2nd EFS folder backup using root explorer
    Just copy the whole EFS folder via root explorer to your SD card or anywhere in your PC. But according users criteria this method is not be good in EFS restore.



    Using of a backup/Restore tool mentioned in OP will backup your whole EFS partition including read / write permission that makes your phone compatible for this task.

    what i did i to flash the rom i want then i did extracted the tar.gz file so you've efs folder extracted so after i've flashed the rom i deleted EFS folder in my phone and i reboot you find no lockscreen and some words in yellow copy EFS backup folder you extracted before to the same location you deleted your device EFS folder then reboot service now should work if not so apply the following commands in terminal emulator line by line and press enter after every line:

    su
    rm /efs/FactoryApp/keystr
    rm /efs/FactoryApp/factorymode
    echo -n ON >> /efs/FactoryApp/keystr
    echo -n ON >> /efs/FactoryApp/factorymode
    chown 1000.1000 /efs/FactoryApp/keystr
    chown 1000.1000 /efs/FactoryApp/factorymode
    chmod 0744 /efs/FactoryApp/keystr
    chmod 0744 /efs/FactoryApp/factorymode
    reboot
