Create a 24bit depth 480x272 .bmp logo image you want and rename it to Startup_480X272.bmp
Put one copy on a root of an SD card, then create an folder also on the SD root named ui_becker and copy same image inside that folder too. Insert SD in your Becker.
Go to main menu -->Settings --> System settings --> Information and then tap fast 3-4 times on a Becker logo than restart and....that's it....
