Dude, I understand that you want Android O, but there's a reason XDA is so adamant on the unwritten policy of "no ETA, no badgering about updates".
What you may think as encouraging comes off as entitled. As far as we know, Santhosh might have fixed several bugs, he might even be running a stable version on his phone right now, but it's not his job to give it to us, specially considering that as soon as a new build drops, people will start pointing out more and more minute bugs that don't matter and the cycle will continue indefinitely.
I know how you feel, I've been refreshing this thread every two hours ever since it got posted, but you don't see me asking for ETAs or asking the developer for the current "goings on" while nonchalantly saying "We're waaaitinnnnnnnnnnnnnng!". You and I have old devices, it's time to understand that officially we never even got Nougat. Be patient.
