1. Get GTrom v4.03 loader
2. Get the"thebox_logobg" bin file
3. Open the loader select background data file
4. click on BIN, select the "thebox_logobg" file.
5. Click download
6. Your box will work again.
The reason this is happening is because you are upgrading from ver4.51 to the latest file. In between these updates the was another update that required you to install the background data file. Those who upgrade from 4.54 will not be affected.
