Sudden shutdown without response

[Impossible1]

Hello everybody ..
This is just the second day of having my Xperia Z2 . Today morning, I noticed a new system update available and then during the update my device suddenly shutdown !!
The battery life was still having 35% !! Moreover, I tried to turn on my device with no response !!
Then I connect it to the charger and the indicator light illuminated but still the device won't turn on since more than 4 hours.

Please if anyone have an idea about this unexpected shutdown 😓

Charge it for 2 hours at least,force shutdown:

After this,do not turn it on.Repair with SUS:
