    Ok so I have already flashed MIUI and i wanna try other roms. Theres a few things i dont understand. One do you have to do a backup after every flash? and what does that backup do does it make it able to reflash the rom? Two do you always have to do a complete wipe when switching roms? and how do you know when to do one? three how do you flash kernals over and know which ones work or not with the rom
    also i wanna flash cm6 and i have hboot .97 and i herd it doesn work with that how do i go about changing my hboot

    A nandroid is a complete backup of the way the phone iswhen you run the backup. You do this so that if anything goes wrong you can restore your backup and it will be like nothing ever happened.

    You make a backup of a rom you would like to be able to go back to.

    You should always wipe data, cache, dalvik cache when flashing a different rom. Sometimes if you flash a newer version of your current rom you don't need to tho.

    You flash a kernel by wiping cache and dalvik cache the install the kernel zip like you do a rom in recovery. Do not wipe data when flashing only a kernel. Some kernels work great for some and are terrible for others you need to try a few till you find one you like.

    I tried flashing that boot image to run cm6 and it broke my root somehow. It took me several hours to figure out what happened and fix my phone so I'm staying far away from trying that again.

    please tell me whether to flash Rom first or the kernel
    i mean that i first flashed the kernel and then the Rom

    Every ROM comes w/ a kernel. If you were to flash the kernel first, then the ROM, the kernel the ROM comes with will replace the kernel you flashed prior. So in short, flash the ROM first, then the kernel.

    To be fair, I've seen at least one ROM (don't remember what) that required you to already have a kernel before flashing. That's certainly not the norm, so just follow frenchy's advice.
