Samsung Galaxy Ace 2 boot into 'root'-How to?

[Szloboda]

Hi all!
I've tried to install 'root' from a 16 GB SC Card with Vol+-Home-Power, and there was nothing shown on the SD Card, only : ./...
Can somebody help me, how to resolve that?

What root method are you using and what instructions are you following?

I will not anyway boot into root, but I have trouble with a new battery. After fully charge, 2-3 minutes after, the capacity falls down to 87-88%. That was with my old battery too, and I don't know, is it normal? Don't know, what's the problem)))
Thanks!)

The method was, to copy a *.zip file to the SD Card, ant boot the phone with Vol+ Home On, and to install from the SD Card that *.zip file. I think it was "superSU" or something so.

You don't boot into "root".

You root the device using whatever method is supplied for your particular device, and superSU or superuser is often installed during the process.

You don't simply install superSU to root your device. It won't even work if your device isn't rooted.
