That guy wasn't experiencing a bootloop.. His device is stuck on the splash screen because he is a noob and obviously did not read up on how to flash his device correctly. I'm assuming the vast majority of people are aware you need to flash the boot.img via fastboot if you use htcdev.com.
Ahh cool, at least that is a simple fix. There been any progress in figuring why some of the flashers can't boot in? I'm still curious as to what is causing it, noticed it in both forums.
