Can it be reset in hardware anyway? I thought it was stuffed for life once configured the wrong way or whatever happened.

You can switch it back from thermostat mode but you have to do it in a funny way like hold one of the pins high for a certain amount of time and then toggle something etc... This forces it back into 1-Wire mode where you can properly reconfigure the EEPROM inside. It's quite annoying to do and you can't do it without lifting legs on the chip.
