I am an happy owner of a Samsung Galaxy S II GT- i9100 android phone and I never updated / rooted my phone before.
It's still using the default configuration and android version is 2.3.5
I heard a lot of nice comments about Cyanogenmod and I would like to try it.
I heard the simplest way to install new ROM is to use CWM but I have no idea which version to install.
I tried with this version: cwm-touch-188.8.131.52-i9100.zip but I cannot simply install it using the default recovering mode because it says that the signature verification failed.
Do you know a simple and safe method to install cwm on my non-rooted phone? is there any way to sign this CWM zip? so I could install it directly wit the default recovery mode?
Thank you very much,
I appreciate the help
