Well first of all i'm a noob when it comes to android... A few months ago I followed a rooting guide and everything went smooth, I was on 2.1 unrooted.

Then 2.2 came out and I wanted to try it so I installed a release that didn't ask for anything, I just put it in my sd card and used CM updater and it worked. I've been running 2.2 for a while now but I feel its very unstable.

Now that the official 2.2 came out I want to reflash but I don't know where to start with the condition my phone is, with the root and everything...

Anyone care to guide me?

Any help would be appreciated
