Installation Notes:

While ironing out several kinks over the last couple months, I’ve found the best practice for installing kernels to be:

  • TWRP
  • Wipe > Advanced Wipe > Dalvik / ART Cache and Cache
  • Install > flash kernel
  • Wipe > Advanced Wipe > Dalvik / ART Cache and Cache
  • Reboot System

Extra Goodies:

Get Notification for New Releases (via IFTTT applets):
