Xperia Z3 stucked on Sony logo then restarts all over again and again

[drewbato31]

Please help.

My phone suddenly turned off and when I turned it on, it doesn't boot.

It is stucked on the Sony logo, then after a while, it restarts and again stucked on the Sony logo.

It goes on and on until the battery is drained and when plugged into a charger, it does the same thing again and again.

Thanks!

Hi,

I experienced the same lately on my Xperia Z3 dual device, and i've tried using the sony flashtool and sony companion, but still unresolved.

Have you in anyway resolved yours. Kindly share.

Thanks.
