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...!!!

get an otg cable and use a usb mouse i will work i have done it a few times
I am posting this update in aid of future Xperia owners:
Problem: I seemed to have experienced the infamous Xperia "Red Light of Death". Phone vibrated 3 times continuously when charged. Screen never came on. Led was only ever RED, and only came on sometimes, sometimes solid, sometimes blinking twice. Computers were not recognizing the Xperia. Neither volume UP or DOWN button presses were ever recognized by any software on either the Win 7 or Win XP installations. However, on a couple of occasions, both computers recognized there was a device on the USB when doing a reset (reset + power). This caused them to try to install drivers. But the drivers, if installed, did not successfully allow any of the software tools to recognize the phone. Nor was the phone recognized in Device Manager, when connected, even when the UP or other buttons were pressed at connection time.
I asked for assistance on 4 or 5 of the net's biggest android forums on this... none came. So I was quickly giving up hope on the Xperia, since it seemed like there was nothing else to do. It might have taken water for all I know, when it was not in my hands, and the mobo might be quiched.
Solution: The phone is charging right now, the screen and color LEDs work fine, the original system is fully intact, and I did not need to reflash a new ROM or anything. However, I'm not exactly sure how I resolved the problem. I'll go through *some* of the steps that preceded this breakthrough. The breakthrough may (or may not) be due Sony's "PC Companion". This is an older version of what Sony now calls "Xperia Companion" (which did nothing good for me, so I went with the older software). "PC Companion" was also useless to me, since it kept insisting on not working unless you allow a connection for it to update itself. But the update always failed, with no clue as to why, despite a/v & firewall disabled. I found a comment where one user said he was able to do a bit more with PCC, once internet was disabled. So I tried that, and yeah, I could at least convince PC Companion to see if it could recognize the phone once the internet was disabled. But just like Flashtools, adb, the Sony Xperia SP drivers and all the other tools, it didn't recognize the phone was plugged in. At least, not the first few times I tried it, using various button combinations. (Up, Down & Reset/Power). Finally, I got a blue light and the PC (Win XP install) started loading drivers for the device.
I'm just not sure what triggered the change. Was it a reset/power combo operation? Was it a slight shift in the motherboard or USB connector that did it? Was it due to (the THIRD install of) PC Companion, or it would have happened with other software eventually? Its hard to say. I think these things contributed to the solution: PC Companion, the reset/power combo press, and just a lot of perseverance, most importantly. (3 days working at it in my case!). If you get this same problem with your Xperia, good luck to you.
(Trust me. You'll need it).
Lent my Sony Xperia SP (C5306) to someone, and it came back in a state where it vibrates 3 times when powering on or charging (it stops vibrating after a while, then starts again). And it won't boot or show anything on the screen, and only a RED led light comes on occasionally. So now I'm stuck on trying to flash a stock ROM on a Win7 system, using Flashtool 0.9.18.6, after installing the Flashtool drivers for "Flashmode" and the SP model, and PC Companion (PC Companion didn't fully install, because it demands updating, and fails on the update -- despite no antivirus installed, and the Windows firewall set to "enable all'). So now my problem is Flashtool won't recognize the phone on the "Please connect your device into flashmode" step, when I press Volume Down before reconnecting the USB cable. I've even tried taking the battery out for a few minutes, no dice.
At a certain point, after hitting the reset button and other buttons, Windows finally recognized there was a phone connected, and automatically installed USB drivers. Yet despite this, Flashtool still wouldn't flash the ROM. I do get 1 error in red saying "ROOT: THIS BUNDLE IS NOT VALID". Presuming this refers to the ROM, I made sure it specified it was for my model (C5306) and its even from the original carrier (Bell). In any case, it still goes beyond that error and proceeds to prepare the files for flashing.
So I'm not entirely sure what's preventing Flashtool from recognizing the phone, since it could be many things. My best guess is the soft or hard brick condition its in: since you can't power down the phone properly, and removing the battery is apparently not the same thing, its not getting to the trigger point that activates Flashtool's flashing. I'm right now trying the "rubberband trick". The idea is to keep the Volume down button depressed with a rubber band, and eventually, the battery wears down and maybe Flashtool recognizes it when it bootloops. I don't get that though, since Flashtool requires you plug the phone in via USB. And if its plugged in via USB, the battery should not ever run down, since its being charged by the USB port.
The phone was rooted, and IIRC, I think my bootloader is locked, so let's assume that. Can anyone help me along on this?
A few days ago, my Sony Xperia SP also could not start up and would keep on vibrating when connected to mains powered charger or USB port of PC. I just wish to record here my experience, hoping it will help some Xperia SP owners facing similar problems.
I tried various suggestions found in various forums but without success, gave up and bought a new phone. The very next day I did a final try. I charged it for around an hour just before I sleep and disconnected it when it was still vibrating. Next morning (yesterday), I pressed the Reset button (marked "OFF" on the back of the set with back cover removed), each lasting about 8-10 seconds. I did not felt any vibration. Anyway, I proceeded to press the power button on the side. And the set turned on! The battery status was shown as 100%. I connected it to my PC just in case drained down battery would cause it to shutdown. I saw a message indicating update was available and proceeded with update which was completed successfully. I downloaded an app and transferred my contacts to my SIM card. (Doing a backup with Xperia Companion will take many hours and I am not sure my contacts could be moved to a non-Sony phone if the Xperia SP fails again later). It has been 24 hours after my SP had revived and it has behaved normally so far.
My thought on this incident is that the problem was not due to battery or some hardware inside the phone. The problem was very likely due to incomplete software updating.
Maybe it is not the right place to ask but my phone started shutting down by itself many times during the day and also it became very hot.
So I decided to recover it through the Sony companion app. I did it many times because it never became usable but it turned black and now it doesn't show anything on the display and it isn't recognized anymore by Sony companion because it doesn't boot in download mode.
It can also be that it is dead in the middle of a recover done through Sony companion.
Now, if I connect it to the charger (or to the pc), it shows the red led for a while and it turns off. It seems that the phone “turns on internally” and then it turns off the red led.
If someone knows what is the problem and can help me, thanks.
Hi, some months ago, something similar happened to me. In that ocasion, I had to visit a technical service in order to
recover my device. They got it, although with last official version of Android. After this, I upgraded it to my choice.
Somebody told me that in these sites normally use "Emma" a flashtool for Xperia Sony. You can download it and try it.
You have to connect the phone to the computer, with Emma running in the computer, and simultaneously push power on
and volume down, if you are lucky, you´ll see that Emma recognizes the device and in the right bottom corner the official
Android for your device. Then you only have to flash the ROM. Obviouslly all data will be lost.
Luck ...
