I also have the SIM toolkit disabled and have seen no trouble with the bars, are you sure its not a script that ATK is killing. When I kill in ATK, i get the 'no signal' icon for a few secs.
Pretty sure. I had put everything except user launched apps into the ignore list. There wasnt a single moto process left on that list. But it I enabled it at autostart, bars, disabled it no bars.
Not to worried about it. Got 99% of the junk off it renaming everything using root explorer.
ATK per my comment didn't work, or it worked but once I went back into the app I couldnt see whats was on the to kill list, just hung at a black screen so I disabled it.
Come to think, autokiller didnt work either for me. When I changed the presets to Aggressive nothing changed. Once I left the app and came back in at one point it said you have default preset would you like to change them and I said yes but it doesnt appear to be saving them.
So 2 of the 4 hacks seem to work, root explorer and autostart. Using ATK and autokiller on my phone arent doing so hot. I rooted using easyroot, dont know if they way he roots is different then the PC method so some apps arent working exactly right that require root. Will need to play more and test whats up.
