Most times after flashing X-BO devices, the display of the device is either white or shows some funny colors. This is as a result of flashing
lk.bin or
uboot.bin file which does not match the device.
Its always wise to make a backup of the following files
boot.img,
lk.bin or
uboot.bin &
logo.bin just in case if things go wrong using a tool like
Miracle Box,
