Viper, I'm sorry, but I really don't think your issues were caused by the task29. I have done it numerous times on my HD2 without any issues. It's really fool-proof for the HD2. I actually had to do it for the first time after trying one of the beta Android builds, as when I booted back into WinMo, the cpu was clocking too fast. The clock and all timers were going way too fast, even after several soft resets and a hard reset. The task29 fixed that issue. Now I do it every time I try a new ROM.
mmeyer, if it comes down to you having to call in to get a replacement, make sure you flash the 2.13 ROM back and undo the HSPL(just in case they actually check it) since the 3.14 ROM has not been officially released yet. Tell the rep what is happening, and they will have you try a couple of things, including a hard reset. Also, you need to make sure your water damage indicators are still white. If it still happens, then they will go from there as far as sending a replacement and giving you the instructions on returning the one you have now.
