It's not as easy to do on 4.5 and lower phones. Actually I haven't found a way yet. 4.6 can do it without too much trouble. Sorry once I find a way I will do it for the older phones.

This Stock L Theme is just what I was looking for for my 8230. I installed it after seeing a post somewhere on this forum from someone saying they had installed it on their 8230 without any problems, but I had lots of problems with random reboots (except for when I turned it off overnight and turned it back on the next morning - then it very unrandomly rebooted every time). Removed the theme, no more reboots.
So... Anyone know of a similar theme that's compatible with 8230/4.6.1?
