I've tried rebooting and now it just gets to the "HTC - Quietly brilliant" white screen and doesn't go any further.
Help please! My wife is 39 weeks pregnant and I work 100 miles from home.
Your Phone is not bricked, its just in a bootloop.
Have you installed TWRP as recovery tool? Have you make a backup before?
"fastboot erase cache" can help (google this words to find a guide. have not much time, sorry
) or you need to recover your backup or you install the os as new system.
