In the last three FW`s for Openbox X7xx are bombs in the FW.
If you have originals Openbox you have no risk to make FW update.
Only the one who have a Openbox-clone must be careful, because this FW works only on an original Openbox and the others will be deledet!!!!!!!!
So post here if there are any problems with your Box after an update.
Look at the pictures, the Words with an O at the beginning (Red written) are the Originals and the other are the clone.
