this has been covered many times, you will need to re-flash your box, hope you have a copy of your sub as you will need to reload it after flashing, there is a tutorial on the forum if you want to make your own image or if your not clued up on assembling an image you can always use one of the great backup images our members have uploaded as the hard work is already done for you, just a few settings to change to suite your area etc
