Question:

I've been using 21911.Sense2.5.Cookie.DinikGlass.Aug.12 and before that the 23128 version. At first it was working fine (and I loved it), but one day it crashed and when I tried to do the regular soft-reset, it froze at the boot screen. The only thing I could do was pull the battery and do a hard reset. However, ever since that day, it doesn't even last me a day until I encounter the same problem again (freezes at the boot screen), forcing me to again pull the battery and hard-reset. I "downgraded" to the more stable 21911, but it didn't really change or improve anything for me.

To rule out a potential hardware problem, I want to try and temporary switch back to a stock ROM, and I was wondering if I can just get the ROM from HTC's US support site and flash my phone using that without first "re-locking" my phone?
I just want to make sure I don't end up bricking the phone.

If anyone has any thoughts/ideas what could have gone wrong with my phone, I'm all ears. I'm more or less a newbie, and the size of the thread here is to say the least daunting.

Thanks in advance.
