How to upgrade from one variation of Cyanogenmod to an additional?
I am rather new to rooting/ placing personalized ROMs on tools ; I ultimately have my phone in a state that I such as, after placing Cyanogenmod 7 on my HTC Desire Z. Given that I've done this, there have actually been a couple of factor launches, and also a small release is nearby. Nonetheless, I do not actually recognize just how to upgrade from one variation to an additional (and also I could not locate any kind of guidelines on just how to do so).
Just how do I upgrade from one variation of Cyanogenmod to an additional? Is it the very same procedure as mounting it to begin with? Will I need to clean all the information on my phone, as I did the very first time?
