Sony xperia miro won't turn on??

My mum sent me her phone - a sony xperia miro (only a few months old) Received today but it doesn't work at all...when it's on charge there is no sign of any life at all. When I plugged it in to the computer it came up with a message saying 'no driver detected'. I installed PC companion, at first it said the phone was connected, and that there was a new version of PC companion available and to download it so I did. Now it's not even showing as connected on Pc companion anymore. She told me she did a factory reset.

Hey quick update - the usb slot in my computer is a bit wonky, when I plug it in now, it says USB device not recognized...and when I go into the details it says
Windows has stopped this device because it has reported problems. (Code 43)
Please someone help!

Xperia3 dual sim, flashed miui rom from z1 on accident

Now pc wont recognize phone in fastboot or flashmode. It had a 48% charge and it did start up into a bootloop 3 or 4 times. thats why i thought i would be ok. Then I realized it was a rom for z1 and it quit startin g at all. it is recognized as something by pc, although it says device not recognized. no lights no nothing.

Update, it is now recognizing my phone in fastboot and I can fastboot stuff. Anybody know where I can find twrp or cwm for the dual sim z3 to fastboot? It is not charging says it is at 1%. But will sit in fastboot without rebooting.

Naaah its not an accident, you went to the Z1 forum download it and flashed it on your Z3 so please tell us its not an accident mate.
Try repair with pc companion !

Sony Xperia Z3 D6603 Hardbricked Help

Hello.
I have bricked my Sony Xperia Z3 by trying to install a D6616 firmware, I have a D6603. It did fail on amms. But the bootloader was installed. My Z3 is bricked. Black screen. Does not turn on. No LED. No vibration. But if I leave the device plugged into the PC for a long time, it is detected as an Unknown Device. I removed the battery and plugged it into the PC. The Red LED blinked briefly and it was detected as QHUSB_BULK. But then as SOMC Flash Device. Sony Flash Tool does not work. It says: Device connected, with USB debugging off. Please help, is my Sony still salvageable
