•
Using the dd command
: The
dd
command can be used to create a raw image of
the device. This command helps us to create a bit-by-bit image of the Android
device by copying low-level data.
•
Inserting a new SD card
: Insert a new SD card into the device in order to copy
the image file to this card. Make sure this SD card is wiped and does not contain
any other data.
•
Executing the command
: The file system of an Android device is stored in dif-
ferent locations within the
/dev
partition. A simple mount command on a Sam-
sung Galaxy S3 phone returns the following output:
