[Q] Bricked Xperia Z? - Xperia Z Q&A, Help & Troubleshooting

Hello, my xperia Z C6603 screen isn’t turns on. The device isn’t rooted.
I disassemmbled the phone and I put the parts in a new frame. After reassembly, the phone worked fine with the new frame and screen and I used it about one week. Then I thought I flash a new lollipop firmware instead the kitkat because the lollipop wasn’t updateable yet in my firmware customization. So I flashed the newest lollipop 5.0.2. ( 10.6.A.0.454_1270-7298_R1E Central Europe1) stock firmware with the 0.9.18.6 flashtool and the things go badly.
The first boot was succesful but after the boot the screen went colorful and I saw nothing besides but if I pushed the volume up or down button I heard the volume sound. I turned of the phone by power on/off and volume up button and I tried to flash other firmwares. The flash methode is always succesful but the phone didn’t work. (I tried the 3 different android versions stock firmwares jb kitkat lollipop.) I used flashtool, emma and pc companion too with locked and unlocked bootloader.
I think the screen is work fine because sometimes after flash a firmware and I turn off the phone first the Sony boot logo is appear but after that nothing happen.
Is there anything else I can do, or is it hard-bricked?
Sorry for my bad English.

I heard you already unlocked your bootloader. How if you install any recovery and try boot onto it. If it success, try install any custom rom via recovery. Let me know the result.

[Q] Cant get into fastboot - Sony Xperia Z

Hi all
I unlocked the bootloader, then rooted the phone then flashed a custom ROM. All went well, then for some reason the phone switched off and for a few hours it would not turn on at all. I left it on charge and eventually I could turn it back on.
However since then I have not be able to boot into fastboot made at all. When i first turn the phone on I am clicking the up volume to get into fastboot, but I never get the sony logo, instead it goes straight to the boot image from the rom (the colourful X), and it does not progress any further, I think the ROM was KA revolution.
Anyone have any ideas? I am completely stuck
and I have followed the steps here using the Update service tool from SONY http://forum.xda-developers.com/show....php?t=2216974
the phone detects fine but it tells me I have custom software and it can't be updated.
fixed now... its all good
Sorry for the bump but do you mind telling me how you got it working?

Xperia Z reboot loop, sometimes weird lines, cant get out!!! Help!!

I have my Xperia Z C6603 with Indian lollipop flashed. One day I told my sis to plug my phone to charger and I dont know what she doid, I think she pressed the power key and the phone rebooted. After a while when I checked my phone it had only black screen, no touch nothing was working. I force rebooted the phone and then it got stuck in boot loop. Then I had the Indian Kitkat firmware downloaded from here >>[FTF][4.4.4] Xperia Z (C6603) 10.5.1.A.0.283 Generic IN (India) - UPDATED<<. Flashing it that time gave me error because drivers were not installed, I installed drivers and then I flashed it, flashed successfully and then I started it, at the choice of Language, when I touched it, the screen went black smoothly and then nothing happened. I force rebooted it. Then I done a software repair from Sony's PC companion. I had lollipop then, it started and after powered by android logo, it went black smoothly and then nothing. Then I tried to flash the kitkat firmware again thinking that it might went bad that time. And now it again stuck in boot loop. At the language select, it went black smoothly and reboots. Please Help!!!

Xperia Z wont boot

So phone wont boot. All that happens is i either get sony xperia boot screen display for a few seconds or battery charging to display.
fastboot still works but flashmode does not.
I have downloaded a stock ftf, from xperi firm - within flashtool (C6603_10.7.A.0.222_1271-2150_R2E.ftf) and flashed the firmware via fastboot from flashtool. now i get the stock blue bootloader animation but then it just goes back to charging so not sure what to do now?
The phone has never been rooted as far as i am aware and not sure if there is anything else i can do? do i need to flash boot image or is just flashing ftf fine? its been a long time since ive had to go through this stuff...any help would be appreciated.

New here and am stuck in bootloop...

So hello everybody, i've been scratching me head at this for a while now.
I have a sony xperia z whose micro-usb to usb port is broken and therefore my pc cannot recognize it.
Now, I am not sure if you've seen the phone but it comes with a secondary charger port kind of thing where it can charge through a dock, and thats what im using.
So i decided to root the phone using kingroot. I was following a guide that showed how to root any xperia device using kingroot and then replacing kingroot with superuser: http://forum.xda-developers.com/xperia-z1/general/root-xperia-running-lollipop-lb-ubl-t3123893
While updating the binaries it said installation failed and i tried looking at other guides. I stumbled upon this thread: https://androidmtk.com/replace-kinguser-with-supersu and followed it even after seeing the disclaimer thinking it would be alright. My dumbass thought everything would be fine and it was until it asked to reboot....
now i'm in a bootloop, with no way to connect it to my comp, and recovery mode not working for some reason (unless im doing it wrong, i dont know).
I believe the loop is a soft-brick (is that the term?) and it turns on shows the sony logo then says "powered by android" goes into the loading screen the stops, shuts off and repeats. I am on lollipop and desperately need help. I have a few school assignments due but can't get my mind off this lol.
ty for helping
Can you boot into recovery? Do you even have a recovery installed?
Flash new firmware use flashtool.. Now xperia z have MM rom..oh yeah
Sent from my C6603 using XDA-Developers mobile app
press and hold power and volume down for 10-12 secs till the phone vibrate 3 times.It will be switched off now.Flash a kernel with recovery included only if you have unlocked bootloader else use flashtool to flash stock firmware.
