calling anybody out over matters that have/have not been resolved by PM is probably bad form. Nobody "owes" anybody anything here.
I'm sort of looking around for a dev aboot.mbn as well. Maybe I just don't know where to look. I thought I saw a mention of a dev edition Odin file, but looking around right now (e.g. DutchDogg), I can't find a tarball that includes aboot.mbn. Does a full dev edition (including PIT, TZ, aboot, etc) Odin flash file from Samsung/VZW not exist in the wild?
On the retail phone, there is no indication that the aboot partition is encrypted - if you dump from that partition the same number of bytes as are in the distro aboot.mbn (for the same release which is on your phone), you get identical signatures. Same goes for other raw partitions (e.g. boot/recovery).
That suggests that a friendly owner of a dev device could maybe dd a partition or two. Or point out a URL that I've missed. The raw dumps would be useful even if they have trailing crap at the end.
