I don't use Z4Root and since I am not an authority, take with a grain. I assumed Z4 was just using an exploit to do a ChMod and set permissions so you could run an app that required access to phone memory. And it ran from boot to boot. I would NOT try flashing a kernel that way.

In fact, I don't see you getting into recovery under Z4. I am quite sure you will still be S -ON.

Why not take the simple leap of going to Root? It is so easy to do, we have cavemen all over this place! Use the latest UnRevoked and you are gravy.

The only downside it that you are out of OTA city. But the XDA guys usually have the updates rooted before the ink dries on the next OTA.
