I really wish I hadn't accepted the 4.3 OTA update, I really do. More trouble than it's worth. Anyway, I did accept it and as expected I had to manually re-root - no problem there. However, although busybox installs successfully it doesn't work; none of the applets function, I can't even get a shell prompt. I've tried several installers, all with the same result. This is starting to annoy me more than a little - and one thing's for sure: I won't be in a hurry to update my Nexus 7... Any clues? Edit: Forget it, it's not busybox that's broken but the script manager/terminal app that I've used for years on all sorts of devices and Android versions... but doesn't work on 4.3 :-( I'm not at all happy about Google's latest meddlings which appear to follow some sort of "if it's clever but we didn't write it then let's change something that breaks it" paradigm, reminiscent of Microsoft in the bad old days.
