Sideloading using ChevronWP7
As explained earlier, in order to install the app that provides access to the file system of the
phone, we first need to unlock the device (similar to jailbreaking on iOS devices). This
method will only work on a Windows Phone that is not locked with a passcode. This can be
done using the ChevronWP7 tool by performing the following steps:
1. Download
ChevronWP7.exe
and
ChevronWP7.cer
files. Note that these
files are often removed and are not always available on the same site. One location
that currently has the files available for download is
http://www.4shared.com/file/
2. Install
ChevronWP7.cer
on the Windows Phone. Note that the methods for in-
stalling ChevronWP7 may require techniques not standard to forensic practices.
Thus, all methods must be tested on a sample Windows Phone to ensure user data
is not lost in the process of attempting to extract the data. One method for in-
stalling ChevronWP7 includes sending it to an e-mail and accessing it. This meth-
od should be used as a last resort when all other acquisition methods fail.
3. Connect the phone to your computer and make sure that the device is not passcode-
locked. If the device is locked and the password is known, enter the password only
when prompted by the computer.
Do not
guess the password on the Windows
Phone as multiple incorrect guesses may wipe the user data.
4. Run
ChevronWP7.exe
and check both the boxes shown in the following screen-
shot and click on
Unlock
. This enables the
developer unlock
on the device and also
enables you to install any third-party app without a Marketplace developer ac-
count.
