When I bought Amiko Viper Combo (non HDD), it was almost unusable. Some software needs to be installed otherwise the card reader does not work, and HbbTV does not work.
As you would not have to suffer, download my backup.
The new OOTB Amiko viper combo features 2 boot logos.
Second, the bootlogo.mvi file, change its extension to .mp4 on your computer and you can view it in vlc or bsplayer.
Explain how to replace it 1st boot logo.
It is called splash.bin and for viewing and editing you can replace the extension in .bmp When uploading the image, put splash.bin in the same folder with the backup files and it will be installed.
Take the photo you want to set up in 1024x576, bmp format.
Resize to 720x576 and rename bmp. to.bin
Resized to 720x576, but on TV it would be 16:9 propotions.
