[Q] Sony Z3, Busted LCD/Digitizer, Doesn't Vibrate, and can't detect in computer topic

My phone fell from the 2nd floor, the lcd screen was really damage, pieces of the glass were falling when I picked the phone up.

It was still ON when I picked it up, but when I pressed the power button, it turned off and I couldn't turn it ON again, does not recognise the charger, doesn't make a sound when I plug it to either the computer or wall plug.

When I got to open the phone, I remove all the glass in the front (no damage on the back and sides). I was thinking of trying to recover the contents so I can easily transfer to another phone if the phone is good as dead. So before I would buy a screen replacement, I wanted to recover the data in the phone, so I tried connecting the phone to the wall plug, if I remove the battery it give me a steady red led light, but if I attached the battery, it gives me a blinking red led light. the same goes with plugging this to a Mac and PC.

So would like to ask is the main board also dead? or is there still hope for my phone?

thanks!
