Yes you can. Download Jungleflasher and extract the key from your Hitachi. Then connect your Benq and load it's firmware into Jungleflasher and copy/paste the Hitachi key into it. The Junglflasher PDF tells you step by step on how to do everything. Just don't load ixtreme, make sure if it asks for any kind of firmware to use the stock. If you have any other specific questions just ask. But if you already flashed a 360 before, I shouldn't really have to explain it.
