How to backup stock ROM?

[Guest XpressAndy]

Hi,

I bought Samsung s2. I to backup the stock ROM before rooting or installing custom ROM.

How do I boot into recovery mode? I tried with volume down + power. It didn't work.

Does stock ROM come with recovery pre-installed?

Thanks in advance :)

There's no need to do a backup because you can find all available ROM's over at xda-developers or on samfirmware.com. Either way, you would need to root and do a bit of hacking to get a backup of a stock ROM, and then it wouldn't be completely stock anymore anyway.
