[AT&T Samsung Galaxy S6] Rayman360:
Note: As long as you have 1.2 or above, you should be able to flash over your existing ROM, as long as you wipe davlik cache first, although its always best to start fresh.

Note: Do not take the OF3 update at this time as it does not have root. OF3 based Ultra Light is still ways off, and the improvements of OF3 are trivial at best.
