XPeria phone not recognized by pc's

[reggi]

Hi,

So I'm working on my XPeria Z2 when 2 weeks ago the headphones stopted working. I have tried everything but nothing works. So I have just installed an app so I have to select the audio output myself all the time. Very anyoing and stupid! 

I tried this morning a last solution => repair with the Companion software from Sony itself (I wish I had never done that!!!!)

After the companion software downloaded the files, shutdown my phone he asked the plug it back it while holding the volume btn down (Flashmode). When I tried this nothing happend, phone didn't turn on and setup on the pc did not continue. So I just hit cancel. Than thinks get from bad to worse. Now no pc on earth is detecting my phone anymore when plugged in. As well, I do not get the charge symbol anymore. It's like the phone is not connected to anything. 

I aswell tried to boot into flashmode myself but I just get a rapid RED and GREEN led and then nothing. The only think that is working is to start in Bootloader modus (Yes, I have unlocked the bootloader modus because of the error with the headphone jack)

This phone is 2 month old and I got nothing but problems with it. So please can you give me a working solution for this????

I tried costums roms but since I can't get into flashmode anymore I can't do anything.

Thanks for the help,

Mikhael

There's your issue Pc companion won't work on a unlocked bootloader - Use Sony Emma http://developer.sonymobile.com/services/flash-tool/

Thanks for the fast reply,

I installed the Emma tool. But as I mentioned above, my phone is not entering flashmode anymore (vol down) I get a fast red and green led and then nothing anymore. So this Emma tool is not helping me either.

As I mentioned as well I unlocked the bootleader just to try and fix the headphone jack problem.

I aswell tried to flash a new stock kernel with fastboot but even fastboot is not detecting any device. What means that the phone is not detecting any pc data connection.

Is there any way I can contact Sony for repair or replacement? For the price of this phone I really except it that is working correctly. 

Thanks

EDIT:

I as well found out that the phone only charges when I turn it of, even when I use an adapter (official and other adapters tested)

If you have the drivers installed then you have an expensive brick (Hard brick)

Also if you are using a 64bit system or Win 8/8.1 then find another Pc to use running a 32bit system

I tried with windows 8.1 and 7 yes, same result. Atm I don't have a 32bit system.

Why is it a hard brick? I still can use the phone when I boot him up. Nothing wrong then (except for the headphone jack and since yesterday the usb plug that is not working anymore)

[Thommo]

Thought you said it didn't boot up

If it still boots up then the issue is the bitrate of your system and a driver signing issue or the drivers aren't installed hence the issue of flashmode and fastboot

I tried my phone on my 3 pc's at home and 7 pc's at the office and on non of them the phone responses.

The problem is that even the phone is not charging when connected to the pc. So I don't think it's a driver issue because that it would charge anyway.

I tried just charging the phone with a wall plug put even that is not working. The phone just gives a fast red and green LED blink.

Thanks for trying to help btw

Sorry but I've tried to help but it appears you have a different issue to what would have been caused by a bad update or bad flash and as you have unlocked your bootloader then I'm afraid you may have voided your warranty and so any chance of a repair may have been lost
