Try it with your own risk, I'm not resposible if you damage your phone and if anything else happens. Below instructions have been tested by me personally and were working.
I can't put any shortcut to my steps, since I'm not going to brick my phone again and test it
_______________________________
My phone had an unlock bootloader.
What have I done:
- used my other charger to charge my sony xperia z ( Huawei charger and cable), but yet the screen is off and only red led is appearing
-changed the operating system that I used, since I was running on windows 8, I changed the pc and went to try my luck on windows 8.1
- installed flashtool and drivers( sony xperia z, fastboot and flash mode) with disable driver signature
- Installed Emma from Sony website, I think it helped with the drivers(though I didn't signin to the app)
- connected phone and as it only blinked a red light , on the computer it would automatically detect a new driver and install it
- I noticed now when opening the flashtool that it detected my phone with usb debugging off ( at least it found out something, rather than the first attempt on windows 8 it would show nothing ) , but it disconnects as It shows in the flashtool process
- tried every attempt to get into flash mode or fastboot but I failed
- unplugged the device and made sure it was off (because when I unplug it, the red led is still on, so I hold power button and volume + for few seconds until it turns off and then release those buttons)
- connected again the device, but now even debugging task on flashtool won't appear, ( when connecting it, it shows phone disconnected in the task of flashtool)
- unplugged the device again and now I went back to the flashtool drivers and ticked to install ( sony xperia z, sony xperia z tablet, fastboot and flash mode) and installed the drivers again
- plugged the device and on flashtool I hold power button and volume up(+) , so the red light goes off and I hear from the computer the device connecting and disconnecting , Held those buttons for 10 seconds and then I held volume down (-) only, so the phone led blinked red and green light and quickly went off.
-now my device is connected in flash mode , so I quickly flashed a (ftf) official sony rom
- tasks completed in the flashtool.
- booted the device and the screen is now on and the sony logo appeared( yaaaaay)
- phone booted and shows battery 2% , I ran quickly and charged it and now the phone is back on and everything works great.
... I know this was long to read, but It took my way too long to figure this, I hope that if there is anyone there who has a similar problem to try out what have I done and might get lucky.
Note: my phone had a blank screen and I couldn't do anything that time and I read hundreds of forums about this issue and tried almost everything, but it didn't work with me.
ALL OF THE ABOVE were of my own, I tried things around and messed a little and never thought that I would get my phone back running, but whatever I was trying was really tiring and It took me hours, to finally find myself, unbricking my Sony Xperia Z.
Thank me If this helped you:good:
cheers.
If you tried out every tip and nothing worked, give this a shot instead of asking again:fingers-crossed:

Xperia Z HELP
My xperia z will go into fastboot and flash but wont work after i flashed it. HELP?????
Sony Xperia Z doesnt boot and vibrates 3 times
Ive got a Sony Xperia Z model C6603 4G/LTE
After ive got some issues with the moisture on the cameras,i got rid of them,also the backlight lcd has some water in it,but 95% i managed to get rid of it
The flaps was closed when it got moisture on the cameras
the main problem is,the Xperia Z worked fine untill it got dead,after heating up a bit the phone,not on of course,it was off by then,and got 3% of battery
now the Xperia Z vibrates 3 times and shows the red LED and then turns off,same procedure over and over again...with the charger hooked in
I tryed the Power + Vol Down,didnt help,aside of the sudden flickering screen
The Sony logo only appeares when i rapidly tap the power button but then shuts down completely
i flashed the ftf of Android 4.3 again via Flashtool with the help of the taping the power button...the flash was a success,but still no signs of booting up
:crying:
can't make the computer recognize the phone
Hi, i've been trying and trying to do this but I can't make the computer recognize the phone. The Red LED stays on and the phone just doesn't do anything. Sometimes when I press vol + and power, it will vibrate 4 times but that's about it. About 1 hour ago I plugged in the phone to the computer and it turned on, it showed me the charging screen and the computer recognized it. Then it shut down and it hasn't turned on again since. Right now it's plugged to the wall with the red LED on but doesn't do anything. Help please I miss my XZ.

Can't do it because the phone is dead. The computer doesn't recognize it, and I'm starting to think it's a battery issue. I left it charging overnight, today it had the green LED and the screen showed a full battery charge. As soon as I disconnected it from the wall charger, the phone died and when I connected it again the LED went back to red as if it hadn't been charged. So I think the battery might be dead, what do you guys think?¿

I've been trying, and no I wast just about to update my earlier post. I connected it to the computer and it showed me the sony logo followed by the charging screen but it showed a full charge. I'm currently battling the computer because sometimes it will recognize it and sometimes it won't. Right now when it does recognize it it says S1 Service but haven't been able to move passed that because the phone reboots itself. Last time it happened the LED went red then green and then nothing happened. So I'm in the middle of that.

did that and nothing happened. The PC recognizes the phone as Qualcomm - Composite #2 (connects and disconnects) and I can't get the phone into flashmode.

Is it possible to do it with a locked bootloader?
weird phone is weird UPDATE!!
If one think something is weird,it can get weirder.
After a few months using my phone without the disabled powerbutton (see story below) I noticed I could not get the screen on by using volume up button, a brief moment I thought it died, but it turned out to be that the powerbutton is back, all things normal again.
The old story how it started :
I I came to this section after a desperate search on my wife's phone while on vacation in Turkey and my Xperia c6603 seemed to have died,
Chronological happenings:
Me and wife at pool
Me having idea,filming and take pictures in pool from wife.
Me thinking phone is watertight, (dangerous thoughts)
Me filming underwater for few seconds at only 10 centimeters of depth.
Phone starting act weird, lockscreen off, lockscreen on, loc....... Around 10 times, then black screen and vibrating : 1 vibrate, short pause, 3 vibrates, short pause, one vibrate.......don't know exactly how much because of me innerself panicking while acting normal on the outside.
Tried to switch on phone, no response...
Connected phone to external batterycasing and pressed charge, phone vibrated again the code of death
Now I realized water entered the phone and it probably entered trough powerbutton.
Me searched Google on wife's phone for this issue and found this thread, worsening my thoughts after read what agony ppl have gone trough when the "thing" happened.
Me opening all 4 """watertight""" (haha) doors to let water evaporate out, waterdamage indicators still white!
Tried several times starting phone after hour in the turkey's sun, 36 Celsius here today!
After while when I kinda gave up the screen was on, wich gave me back the year that I would die earlier because of the things happening to me while not showing on the outside.
Then noticed the text downleft in screen: safe mode!
Tried restart but powerbutton nonresponsive, noticed powerbuttonfunction shifted to volume up!! Wich looks like the phone somehow noticed something must be wrong with the powerbutton and made itself usable again by relocating this function to another button.
Phone is fully functional again, had to download app though to lock screen cause volume up only unlocks and pops up shutdown/Screenshot dialog when screen is on.
Dat weird phone!
I've done searching on this forum but I haven't found any answers that are specific to my issue. I just bought this Xperia SP from a retailer online. It may be a refurb, I'm not sure, but it looks brand new. Anyways, when I opened the box and tried to turn it on, nothing happened. Ok I thought, I'll just charge it. When I charge it, the red light on the bottom just comes and goes. Stays on for a few minutes, then goes off for a few minutes. I let it charge for almost 6 hours like this and nothing has happened. When I plug the phone into my PC you hear the USB connected sound, but right after you hear the disconnected sound, and nothing shows up in device manager. I tried the Vol+ and Power button combo and nothing happens. I tried holding the reset button on the back for 5-10 seconds and nothing happens. I get no vibrations at all. The phone is not detected in any program like SUS, Flashtool, or PC companion. Some times when I press the power button I get 2 red short flashes, I have no idea what this means as it's not consistent, and only happens every once in a while. Anyways, I think I may just return it and hope for a replacement :\ Any ideas?

Faced with same issue a month ago, after a buy Xperia SP from Ebay. Same symptoms: red light while charging, sound on PC when I first time connect with it, with no luck at all. First of my attempts to fix this, is changing my usb cable, then installing universal android usb driver, but nothing helped me. Then I just ask google for my problem . This is an answer that helped me:
Xperia SP comes with a non removable battery.So turning off in this condition is not possible by removing battery.The volume up+power button doesnt work in Xperia SP unlike other phones.The solution is given below.
Remove the back cover of Xperia SP and look for a small yellow dot on mid bottom with “OFF” written below it. Check the image below.
Now “Press & Hold Down the OFF Button, using a tip of pen or any other pointed object for around 10 seconds”. Phones vibrates and will be switched off automatically. Check image below.
P.S. Don’t use very sharp objects as it may damage the OFF Button.
Now phone restarts.
After restarting we found that our Xperia SP got back to normal temperature and everything was fine. :smileyhappy: We were able to charge our Xperia SP again, device was cool.
Hope it will work for you also

I don't think you read my post thoroughly. I tried the reset button on the back, it didn't do anything.
Plug the phone into the computer, reset your device (yellow button), than immediately press and hold volume down key. If computer respond with sound and green led notification on phone, next step is SUS (Sony update service) to factory reset your device and start with latest stock firmware.

That's actually a good idea and I hadn't tried it. However, after trying it now it still didn't work :\ Still nothing. It's as if my reset button doesn't even do anything. I push it with a small object and it doesn't feel like an actual button, there's no movement to it.
I get the green LED for some seconds but then it turns off and boots back up to the red LED again. Any help?
I believe the problem was because of no charge or the phone was too hot?
Anyways, I'm glad to say that I let it charge first and then let it cool down, download a stock tft firmware and flashed it using Flashtool. Now everything is fine until now.
Going to try and see if I can install that 4.4.4 ROM, again...
I encountered that problem when i updated my phone my phone previously, i just reflashed my ftf.
Sent From My Xperia Sp (C5303)
I had a simmilar issue , look what you have to do:
1- Connect the phone to the PC , you must see the red light , if not wait few minuts , you must see it.
2- When you have the red light , put the phone near of you and keep you eyes on it for 5-15 minuits , you must see the green light turn on.
3- When you got the green light take your phone , and even if it goes off , now hold the VOL - botton and then hold the Off botton in the bottom of back of the phone for 7-10 seconds , you must the the green light turn off and on again. (you have to do all of that while it's still connected to PC)
When the green light turned on again that mean you are on flashmode , now better to use Flashtool to flash a firmwate.
Notice: the phone may get disconnect while flashing , so you must to flash it in 2 levels: first one by excluding the system.sin then flash it.
The second time you redo those steps to get into flashmode again , go and flash only system.sin be uncheck the wipe boxes , and by checking all exclude boxes but the system one.
You may fail flashing the system many times because it's the longest step , so try to charge your phone more time and try to flash it again and again.
I've test everything...!!!

Is it completely dry and if it is then do you see sony logo or blue led notification?if sony logo shows up try flashing stock ftf via flash tool
And if blue notification then try to unblock volume up button i thing it is stuck so it puts your phone to fastboot mode when connected to pc hence blue led and when you try to turn on your phone without connecting to pc it hard reset your phone hence three vibration and phone shuts down...
Try unblocking volume up button by pressing hard volume up button many times then connecting to pc until there is no blue light turning on...and after unblocking the button try flashing stock ftf via flash tool...
Be careful not to press it too hard or you will damage your phone..!!
Get phone working again and get it replaced if under warranty to avoid future problems...

My English is not good, so I used Google Translate. I have a xperia10iv engineering prototype. I switched its firmware slot to b by mistake. Now it cannot start normally. The specific performance is that the screen cannot be turned on. When it is connected to the computer, the red light is on, which can be recognized. to the device on port 9008. Is there any way to salvage it?I can't get to green light or blue light mode now (long press volume up/minus to connect usb)
