To update this box, please do as follows:
Unzip the file and put on the root of a USB stick. (not in any folder or anything)
Then enter MENU on DMB-111/112HD, go to playback and choose Music. Click on the file and wait until it has updated (100%)
Then take off power (take power cord from wall socket). But first when reaching 100%!
Then enter the menu, and choose "factory reset". Standard code is 888888 ***remember to do so***
Now you can seek channels and then it all works again.
