Hi there,
I may be able to assist you. first let me start by saying this is not an pure android device, it has not met the specs required by google to carry the android name. there is very little support for this low end tablet. in order to change the boot animation you need to unlock the boot loader on the device. this may not be possible, however there are ways I can still display your logo after the main logo, and I can still force your video to play when the device turns on. I would be willing to investigate further getting these things done for you for the bid price. payment would be expected at delivery and my work carries a 30 day bug free warrantee.
