Go here:
[ROM][CWM][EL30] Stock+Root+Deodexed - xda-developers
DL the EL30 file and then copy it to your SD card.
Run CWM, do the required wipes, and flash it.
You'll have a stock + root version of EL30. It's the most basic of the customs.
I'm assuming that you've done this before. If not, check the appropriate QBKing video.
BTW, the notification messages came back today on my Epic after a week's vacation. I did the install/fail process again. Seems to work for about a week. I'm waiting for the EL30 custom rom I want to be posted...
