On my box only use original images, and the 7.4 image has the same Bootlog as Openatv 7.3.
My comment was about that.
In your opinion 7.5 developer what is an unofficial image? is it compiled by some kind of pseudo command?, This is an image for developers and betattesters. as atv7.4 was previously, it has not yet been officially released. There is also an opportunity for a simple user to try it. And about the bootlogo to you in another topic openAtv 7.4 devel Images
although the name of this theme is no longer relevant after upgrading from 7.4 to the stable version openAtv 7.4 devel Images
