Boot problem!

[thiagomatuo]

I tried to update my Xperia ZL but it failed and now, when I try to turn it on, the SONY logo appears and the phone shut down and star to turn on again and repeat the process... I tried the repair in the Sony PC Company, but the same happens!

Please, help me!

Oh yeah! after the SONY logo appears, I continued pressing the power +vol Up and now the charging icon appears. I need to wait to full charge or I can try to turn it on?

Hey, that worked. I tried again and the phone turned on! But when I unppluged the device turned off and I tried again, but only works some times.

hey i found the exact same problem... while updating and SONY Companion just went wrong .. it was not responding and my phone cant be booted at all..

now the SONY logo keeps.. restarting 

so could you repeat your step to solve this?

1) connect to the wall charger

2) let it charges for an hour+

3) power button + volume up botton

and it works?

Thanks!

The first, I only connected the phone to the wall charger pressing power button + Vol Up and the device turned on. But it works only some times to me.
