I have tried them before, and you know what they said, search. I could not find anything detailed like steps, pictures, or how to do it other them saying here is the rom, install it. :/
nizmoz,
I can only refer you to the methods I used. Based on your MR signature, I'm assuming you're also doing this on a Mac.
To root using a Mac (and also install CWM Recovery), I followed
these instructions. Only important info I found missing from the instructions was to make sure USB debugging is checked in the Developer Options of Settings before you get started.
After rooting and installing CWM Recovery, I'd suggest making a Nandroid (boot into recovery and follow the prompts to make a backup). This will give you something to fall back on should you have problems installing the custom ROM.
For instructions on installing the CleanROM ACE (4.05), I just followed the developers instructions from his website
here. Just download the ROM using his provided link to your Mac, copy it over to your internal SD card partition (anywhere is fine, I usually put it in the existing Downloads folder)--I did so using the
Android File Transfer application. Once copied, boot into recovery (volume UP, home button, power button simultaneously) and follow the rest of his instructions.
Best of luck.
