I cracked my Apple Watch 2 screen and replaced it with a new on my own. However, after the screen shift, the watch fails pairing to any watch. I have tried it a hundred timed on five different iPhones but it always fails. What might have gone wrong? The display shift was easy and was done without apparent problems. Thankful for input!

I read here that the only way to get the watch to work again is to ‘reflash new firmware by ibus 2...’:

Can anyone confirm that this is what needs to be done?
