INSTALLATION

  1. Watch >> THIS <<
  2. Uninstall any CPU control apps, tweaks and scripts etc.
  3. Recommend: Install Wanam DVFS disabler for greater kernel control
  4. Recommend: Backup your current kernel with TWRP Recovery
  5. Recommend: Install Synapse app from Google Play and rate it ☆☆☆☆☆ !!
  6. If Synapse app is installed and using with any current kernel: device settings > applications > synapse > FORCE STOP & CLEAR DATA
  7. Flash SKyHigh kernel with CWM or TWRP Recovery
  8. After boot (wait at least 60-120 secs)
  9. Open Synapse
  10. Tap "Understood"
  11. Make any change, and tap the "" to apply new defaults
  12. After setting and applying any GPU freq changes, don't forget to tap [Apply GPU Governor Settings] in Synapse GPU section
  13. Any issues, please check Posts #1-3 and search the thread BEFORE posting
