[Wildfire Q&A, Help & Troubleshooting] Guntram:
Hello heavy_metal_man and thanks for chiming in!

I have my phone always on a charger, but sometimes it seems to be shut down and remain unresponsive until I remove the battery. So I do rule out a battery issue (though not any other hardware issues :( ).

This happens sometimes(!) when I'm on charging (via computer USB) and simply shut down the phone. It becomes unresponsive, the red LED still glows and I have to remove the batter.

Trying to get a RUU with the HBOOT 1.00 included resulted in the following (using OpenRUU from http://xdaforums.com/showthread.php?t=711298 and a RUU downloaded from http://xdaforums.com/showthread.php?t=1275680, namely the first FROYO ROM, second download link) :
