When I first got my Wireless Unit it also crashed at least five times until I finally managed to update the firmware on the EW-WU111.
What seems to help is to update every component's firmware using the SM-BCR2 charger (and windows e-Tube app). That should decrease the chances of the mobile app crashing. You can then use the mobile app to update the EW-WU111. And if it does crash apply the same fix as you did before, or have a look at

It is the nature of how firmware updates have-to-work. The problem is the wireless unit itself and its updates IME.
What happens? I'm guessing...
1) You connect wirelessly to Di2
2) You D/L an update.
3) The Di2 system applies the update...but to finish the update, like in Windows it must reboot the updated component
4) The wireless app (and the D-Fly) looses connection during the reboot, because well--the connection hard-hangs up.
Which means that E-Tube and D-Fly cannot handshake-check that the update worked...so they thought vomit at one another. E-tube errors out, and Di2 soft-bricks to protect itself thinking something went wrong.
