Root Stuck Unrooting EVO 4G

I was messing with root for a few days and I found that I really don't need to have it. I am trying to remove it mainly because there is an OTA update for my device, among other reasons.

I rooted the device using the revolutionary method. I got S-ON back but I can't find the correct for my phone. The HBOOT version is 6.17.0001.

Also, how do I restore the stock recovery image for my device?

Any help would be appreciated.

Thanks in advance.


DON'T PANIC!!!!!!!!!
Never mind, I figured it out. I had to run the executable on a windows machine and not mac. Now my only questions is, when I go into recovery, it shows a red exclamation mark. Is this normal?

yep that means you have a stock recovery and you are not allowed to use it. so looks like you are now officially unrooted.:(
