I tried rooting a Samsung Galaxy S3 GT-I9300 running Android 4.3 using the latest CF-Root available (version 6.4).
This installed ClockWorkMod on the recovery partition.
After that, I did a Nandroid backup to a 1 Gb SD card.
I'm not sure that the root access was gained through CF-Root (because accessing as root from the adb shell does not work)
but I could see however that CWM was "copying" or at least reading hundred of files.
But trying to access the Nandroid backup from either Windows or Linux, I can only see two folders : "Android" and "LOST.DIR"
as well as a "default-capability.xml" file.
The "Android" folder only contains the following folder structure "data/com.android.music/files" which one is empty.
The "LOST.DIR" folder is empty too.
In Linux, the "fdisk -l" command lists four partitions from the SD card, but tells that I probably selected the wrong device.
Furthermore, "fdisk -l" reports that the four partitions have starts and ends physical/logical that are different and suggests : "(non Linux ?)"
Is this due to the filesystem used by Android on NAND memory that would not be recognized by Linux ?
How to check if the Nandroid backup was performed correctly and access its content in Linux ?
Thank you very much for your help.
