Wait for Install complete.

Reboot

Reboot to system and let the first boot finish.

Dirty Flash

Same ROM only

Dirty flash is for updating DerpFest to a newer build on the same Android version.

Flash the update

Boot into recovery and sideload the newer DerpFest zip.

adb sideload DerpFest-vXX.X-YYYYMMDD-yourdevice-Official-Stable.zip

Wipe cache only

After flashing, go to Factory Reset → format cache partition.

It is recommended to format cache if you are dirty flashing from a previous build.

Do not format data for a dirty flash.

Tips

You'd better use only natural color mode and disable blur effects.
Format cache when you make dirty flash.
You'd better flash the recovery.img that is located inside of .zip file.
