Ionic stopped working midway through update

[SunsetRunner]

I tried updating my ionic last night and midway through update it shut off and won’t come back on. 
I tried:

turning Bluetooth off and on - now it can’t find Fitbit 

held down left and bottom right buttons to reboot - nothing 

reinstalled app - no change

it has been charging for over 12 hours and no change 

reported it to help desk 

it did this on previous update but I was able to reboot it and get it working again.
