Flashing a new recovery partition
There are mechanisms available to flash the recovery partition of an Android device with a
modified image. The
Fastboot
utility would facilitate this process. Fastboot is a diagnostic
protocol that comes with the SDK package, used primarily to modify the flash file system
through a USB connection from a host computer. For this, you need to start the device in
the boot loader mode in which only the most basic hardware initialization is performed.
Once the protocol is enabled on the device, it will accept a specific set of commands that
are sent to it via the USB cable using a command line. Flashing or rewriting a partition
with a binary image stored on the computer is one such command that is allowed. Once the
recovery is flashed, boot the device in recovery mode, mount the
/data
and
/system
partitions, and use adb to remove the
gesture.key
file. Reboot the phone and you
should be able to bypass the screen lock.
