[Fire TV Q&A, Help & Troubleshooting] Pachacouti:
Yeah, I'm using the origional fireiso from 6.2.7.1 days, is there a newer version? I've just tried so many different roms I cant understand why none work, when they all did before the black screening. My very active imagination tell's me it's something to do with vendor, in that I 'THINK' that when trying the markus stuff, something I noticed was background blah blah, and I thought this is contained in VENDOR, and to the best of my limited knowledge, the part I seem to be stuck with is the boot animation screen telling my thinking that this is the scource of the problem.

Alas, I've copied my 'test's' for today, and post them here in the hope someone can shed some light, please notice my correcions where I've overlooked and corrected:
