Guys,
i recently bought a Samsung Galaxy S2, G version and rooted with a custom kernel.
Now my screen is sometimes flickering, and i want to send it to warranty.
How can i unroot my phone and restore back to factory setting?

1. Is it enough by performing hard reset?
2. If i am using SuperOneClick to unroot, is there any file that i should download?
3. If i update my phone to latest update, is it will be the same as unroot?

which method should i use?
or should i follow these step:

i am not sure if link above is sufficient enough or not

anyone had tried using xperia C?

phone recommendation actually is for closed question and not meant for discussion.
put a spec and, one question and one answer.
there is issue highlighted before this to not dispute the thread.

since this is android general question, why cannot ask here?

orry to bump an old thread.
but want to confirm which one of it can work without internet?
Chromecast or Miracast?

example, if go holiday and my son want to watch our short vacation video, can i cast it to the hotel TV without internet? few islands like Langkawi and Pangkor really have bad internet connection.
