Well if they can't switch it on then they can't see the custom binary...?

Since then I haven't rooted it as I'm scared that it could brick again. That's why I wanted an official KitKat upgrade which Samsung don't give for bs reasons!
You can just use VRoot. It's easy to achieve root with it After rooting and installing a custom recovery ALWAYS do a nandroid backup before trying to flash or modify ANYTHING! That's what I do and never spend more than 10 mins (the time required to restore my nandroid) with a bricked phone :P
But the thing is that I had KitKat by Maclaw for a while. Then one evening it was charging and it just died without warning. It was dead for one day and then it switched on but it just showed bootlogo and switched off. Then when I realised it was semi hard bricked.
But then wouldn't I lose the warranty? And Maclaw's CM11 ROM was the best, I miss out on so many good features on stock and it's so much slower than CM11. I just don't want to end up having another bricked S3 mini though.

Don't bother trying to revive it if it's hard bricked. Because they won't find out about the root if they can't turn it on.
