If you send it me, I can assure you that I will make sure it will completely erased and will make no attempt to extract any personal information from it. I have no interest in putting anyone's information at risk.
As diamaunt said, it's an easy promise to make, because in its bricked condition, I couldn't access any information even if I were so inclined, and the very act of unbricking it (indeed *any* update over USB) erases the entire partition where any personal information would be kept.
However, I will respect any decision you make regarding the device.
