Before we start, you'll need:

1. Download O1_boost.zip
2. Custom recovery credits: drellisdee

After downloading (1) and flashing (2), it's a walk in the park:

1. Reboot into recovery (vol down + home + power) or via adb or whatever.
2. Toggle USB, copy the .zip you downloaded (1) over to your sdcard.
3. Flash zip from sdcard option, choose the .zip. Reboot.

How to confirm if JIT and HW accel are active?

For JIT, run a linpack. If it scores around ~7-7.5, it's active.
For HW acc it's not so easy but homescreen scrolling should be snappier.
For the fix, run a Quadrant, if it scores above 1000 or around that, it worked.
