Have you used the RESET button next to the SIM tray? That might be enough to get it to power up. If so the first thing to try is to download and install PC Companion, and then see if it recognises the device and allows a "repair installation" of the firmware.

I've not rooted a Z3 myself, but my understanding (from reading this guide) is that you have to unlock the bootloader and use flashmode to install DooMLoRD's kernel (boot.img) before you can gain root by flashing SuperSU from recovery.

Thank for the reply. I've tried to reset from the sim tray but nothing happened. I've tried already to use PC Companion but it doesn't recognise my phone.

To clarify the current situation, you have a constant red LED and if you hold the POWER button for a few seconds you feel no vibration?

 

[silvia89]

No. When the phone is not connected via usb, the light is completely off. When I connect the device with the charger there is a constant flashing red light. When I connect the device to the PC the phone is completely dead. But I do feel the vibration when I hold the power button.

One more thing. When I plug the phone into the PC I can hear the sound of a connected and disconnected device, and it keep making this sounds every now and then. When I try to turn on the device I can see the red light and then a green light that fades out straight away.

I was trying to install cmd boot.img with fastboot not flash tool... Sorry. And I followed this guide. How to Install CyanogenMod on the Sony Xperia Z ("yuga") - CyanogenMod But when I wrote 'fastboot reboot', the phone gone down.

 

[silvia89]

Alright. Had to pay 15 quid but at least my phone is working now... Thanks anyway for the support!

That's a (very) small price to pay - glad it's working again. Now, before you do anything else... install a recovery and make a backup!

Out of interest, what was the solution? The fact that you felt vibration and saw the LED change colour suggests that it wasn't hard-bricked.

 

[silvia89]

Yes it was a very small price. Honestly I was hopeless that they would repair it... But all they said was that they downloaded all the drivers and they flushed the firmware... Not sure what they exactly did... I didn't sleep for one day to try and fix it and they did it in 2 hours...lol I think I will never try to root my device again...

They just did a firmware flash most likely

My phone has just done the same thing! Where did you take it to be repaired? because I would prefer not to have it sent off.

Glad to hear you got it fixed. I rooted mine the first they a got it, then I upgraded to Lollipop and it's working great. Though I've been doing this for ages with many phones, so I usually know how to fix things up if they ever softbrick.

How can I fix mine, it is just a blank screen and nothing happens when I hold the volume buttons or power. But when I plug it into my pc the computer does not detect the phone but the phone vibrates when I hold the power button!! Help

Hold the volume down key and connect the USB to the phone a green light should come on or red
If I am confusing at all look up flashmode for the device
