Help with Bricked Z3 6033

[Wong17]

Hello, I need help with my Z3 with these symptoms:

-When plugging the USB to a PC, it won't show up. But it does pops a sound on the PC; the S1 Service appears on the device list. Dissapears when unplugged
-When plugged to a PC the phone flashes a red light for a moment, then a green one really fast before the led goes off again.
-If i hold the power button, the phone vibrates a bit. No screen or led are light give any signal.
-If I hold the vol- button plus the power up button, the screen goes up and Sony - XPERIA logo briefly. But it won't start at all and goes back to black.
-If the vol+ plus power buttons are holded together, the phone will vibrate 3 times.

It was working fine just before i tried to install ZyxxOS. I rooted it previously with Kingo ROOT. Then used the Z3-lockeddualrecovery2.8.26-RELEASE.combined. Used the Install.bat. On the dual recovery mode I installed the ZIP, when it looked like it was done I cleared the cache and followed the dialogs. Then a message poped up saying my device was not rooted and offered me to root it. After it the phone went black and the CMD looked like was doing nothing. I left it like that around 25 mins and then unplugged the USB. After I tried to start the phone it didn't worked anymore.
I'd be really glad if someone is able to help me :crying:

Seems like a drained battery and a system corrupted. Try holding the power down for 30 secs, to make sure the phone is turned off, then leave it charging for a while, and when I mean "a while" Im saying put it in charge and go to sleep. The next day the phone will be with full battery for sure, then, download and install FlashTool and install the drivers from the folder of the program after installed, then try the steps mentioned here:

http://forum.xda-developers.com/xperia-z/general/tutorial-how-to-flash-stock-roms-t2240614

The tutorial is for the Xperia Z, but the steps are basically the same.
On the newer versions of flashtool, there is an new option to download the stock firmware from the program, wich is usefull if you dont know where to search, and more secure, since the z3 has many different models, make sure to download the correct firmware for the model of your phone, to know the model, just open the chip flap and you'll see a small piece of plastic above the sim slot, pull it and you'll see some information, look for the model, ex: "D6653"

answer if it works!

Wish you the best!

Thanks. But is it needed the device shows in my computer?

Also, when I try to use the Flash tool I don't get it to see it on the list.

Also, I charged it a whole day, but it never appeared nothing on screen, just the red light blinking.

Looks like you're connected, but you don't have any FTF's downloaded. Download FTF for your model, put it in C:\users\Wong\.flashTool\firmwares.
Then while holding volume down button connect your phone to PC. If it says "Device connected in flashmode" you suceeded. Then click on lightning icon on flashtool select your FTF and flash it. Hope I helped.

You also need a unlocked bootloader to install ZyxxOS on your device.

Yep, seems that you only need to download the FTF for you phone, you can use XperiFirm option on the Flashtool to download the firmware for you model.

Then just do what Nojus said, connecto to the PC holding Volume down, the flashtool will recognize it, the led will light up and you're set to reflash your device again.

I think you tryied to flash the ZyxxOS without unlocking your bootloader, then you corrupt all your system and It went to a softbrick state.

Post the results here! :fingers-crossed:
