Well, I made the jump to Jelly Bean from .215 leak last night. My phone seems ok, but should I do an FDR? I tried do a clear cache process, but the option never appeared after booting into recovery. The little android with the orange triangle over his open chest just statyed there. I didn't get the 4 or 5 options that were in blue on ICS. Is there another method for clearing cache now with JB?
