Ok, I'm totally new to all this rooting and flashing custom kernels and all that, but I'm doing pretty well with it. I just don't fully understand all the bits and pieces yet.

Yesterday, I loaded JoeyKrim's 0.5 custom kernel, and I had a lot of trouble getting it to work with a custom theme. I want to load his 2.0 kernel today, and I want to try a theme again, but my question is about reverting if I screw the phone up.

I went into Recovery 3.0.8 and I backed up my system and my data. If I screw the phone up badly, can I just go in there and restore both of those and be back where I was?

Seems to make sense to me, but I just want to be sure.

 

Right (and I've done that twice now), but I don't want to lose everything I've installed and set up since doing so.

 

I had a theme for a while yesterday, although I couldn't make phone calls (my wife said I basically had an ipod touch at that point). It was really nice looking.

I'm going to try following some detailed instructions on pushing a theme and see how that does.

Also, regarding my original question: I downloaded an update zip from Joey's kitchen and it froze my phone. I went back to recovery and restored my system and it booted up fine again.
