Rooting can break something called an e-fuse if the device has something like the Samsung Knox technology. If that happens, then you could have problems.
To be honest, I’d just not bother with it. Rooting undermines the app isolation (such as it is with Android) that provides much of your security, so I generally recommend that people don’t do it. That’s quite apart from possibly breaking something if you mess it up.
You may be able to get rid of the vendor apps using adb, but (and here’s where I start being vague because I can’t remember) the vendor apps are likely to be on the base ROM, so may be reloaded by madic even if you got rid of them.
Or something.
Anyway, just don’t root it. It’s not really worth it.
