Just joined to voice my appreciation. I have a GooBang Doo "2017" KODI Box labeled as M8S-II (s905/2gb/8gb ROM/1Gbit/4K, etc etc) and was getting frustrated with the changes in pass-through from Jarvis to Krypton (I understand the reasons) but the box had a very cobbled together Android 5.1 (not 5.1.1) build on it. So I did some research and came across LibreElec and kszaq's 7.x thread. So I figured, what the heck, won't hurt to try.
Let me say a few things as a developer myself:
1) I have NEVER seen such a clean kernel boot log, I was impressed.
2) Using the default image, everything worked out of the box for me. Saw eth0, wlan0, usb sticks, usb wireless keyboard and even my stock remote worked. What was most exciting was that CEC worked with the stock remote whereas before it would just alter the Android volume level (causing all sorts of problems audio-wise.) I was so impressed with this that I had to call my wife over to show her which of course, did not impress her like it did me
3) The speed; I figured with just a bare minimum OS and KODI it'd be fast and light, I was shocked to see how much so. Krypton on the NAND consumes 41% memory whereas your build consumed 9% -- I realize it's not exactly apples-to-apples but was another scenario I called my wife over who by this time was getting annoyed with me and my geekdom.
4) Playback from my NAS and Addons was flawless. I now have DTS + friends back again as well. Finally my wife was impressed as she watched an episode of Mayday and was shocked how fast it found and loaded the episode compared to what we're used to.
So now that I have a working start, I have decided to give 8.x a whirl and see how that goes. I've been humming and hawing whether to try and backup my NAND but since it's a broken junkpile I'm leaning towards not.
Basically, it worked better than my wildest dreams would have imagined.
Anyways, I just joined to voice my appreciation and admiration. You have done a very good job Sir, color me very impressed. You've made me a very happy geek, husband and father (sure my kid will be impressed too when I show him.)
