The messages don't connect. But guessing from the context, there's something about the device later.
It says they tried to operate the device on the giants, the device stopped working, and then it made a strange sound and started breaking. Then it says that they hurried out with it.
It seems that they broke the device because no one knew how to work with it. Do you want to find a part of the device at least?
