INSTALLATION

Watch >> THIS <<

Uninstall any CPU control apps, tweaks and scripts etc.

Recommend: Install Wanam DVFS disabler for greater kernel control

Recommend: Backup your current kernel with TWRP Recovery

Recommend: Install Synapse app from Google Play and rate it ☆☆☆☆☆ !!

If Synapse app is installed and using with any current kernel: device settings > applications > synapse > FORCE STOP & CLEAR DATA

Flash SKyHigh kernel with CWM or TWRP Recovery

After boot (wait

at least

60-120 secs)

Open Synapse

Tap "Understood"

Make

any

change, and tap the "" to apply new defaults

After setting and applying any GPU freq changes, don't forget to tap [Apply GPU Governor Settings] in Synapse GPU section

Any issues, please check Posts #1-3 and search the thread BEFORE posting
