help?

Hi. Stock rooted through revolutionary. OTA updated being push, have rejected it, now its automatically pushing with time but after giving me "Download Fail". Will this prevent it from updating itself? I don't want to wake up one morning and it updated itself. Also, is there any way to flash the update without wiping data? Any help would be appreciated! Being lazy to go through the threads for answer..lol. Thanx
