I am a newcomer,so go easy please.
I have spent the last few weeks researching all things root to do with my galaxy s2,I am pretty much ready to go but I am unsure about what is installed on my phone.
I got the phone second hand, it has superuser and this works for things like greenify etc, so I assume the phone is rooted, but when I boot into recovery there is no clockworkmod or anything like it.
So then I dug deeper and read warnings about trying to install clockworkmod with custom kernels etc.
How do I know what method was used for rooting, and what type of kernel I have?
Basically I want to nandroid backup before I start tinkering.
Model is GT-i9100 4.1.2 Kernel 3.0.31 - 889555.
Thanks for your time, I don't want to brick my phone on my first venture!
