Just wanted to chime in and let you know that I flashed 2.8 on my LS980 last night and haven't had any issues with it. I'm running TWRP 2.8.6.3, UltraPop 1.2 (ZVG based rom), and Xposed. I haven't messed with any settings yet, but I will start pushing it in the next day or so. If I come across any bugs I'll let you know. Thanks for developing this!
