I've got the same problem. Tried to update with flashtool, everything seemed fine, no errors appeared but phone doesn't boot up, doesn't react to any buttons combination and is not recognized by PC.
[Xperia Z1 Q&A, Help & Troubleshooting] Rekoil:
Quick question before I go take my final, what version of FlashTool did you guys flash with? I ask because 0.9.13.0 was introduced to add support for Xperia Z1 among other devices. If you used an older version of FlashTool then that might have caused these issues.
[Xperia Z1 Q&A, Help & Troubleshooting] wezzel98765:
I did use an old version yes. I ued version 9.11 ... so possibly completely my own fault if that's caused it

This could be what's caused everyones issue

Guys, what version flashtool did you use?
[Xperia Z1 Q&A, Help & Troubleshooting] wezzel98765:
Although it does say version 11 change log... Version fully compatible with all 2013 devices (Z/ZL/Tablet Z etc etc)
[Xperia Z1 Q&A, Help & Troubleshooting] chivuletz:
9.11 mee to.... now i see its new version available 0.9.13.0... what to do now ?
[Xperia Z1 Q&A, Help & Troubleshooting] wezzel98765:
Maybe nothing we can do?

I am sending mine back under warranty...
[Xperia Z1 Q&A, Help & Troubleshooting] wezzel98765:
Update!!!

Have just plugged phone in, it now has LED light to say it's charging. Going to get it plugged in to Flashtool and see if it will detect it ...!
[Xperia Z1 Q&A, Help & Troubleshooting] chivuletz:
What you do man ? tell me pls... I took my phone to a local service.. and the guy tell me he need to open the phone...to charge the battery manual...
[Xperia Z1 Q&A, Help & Troubleshooting] wezzel98765:
I now have LED charge light but still no life

COmputer says USB device not recognized

Have then tried rebooting the phone using VOL UP and POWER and the phone light blinks red and the phone vibrates 3 times, then solid red again.... no connectivity to the laptop though :(
[Xperia Z1 Q&A, Help & Troubleshooting] minhnd:
Hi, last night I met same case like you. The problems caused by Sony PC Companion broken when updating. So my phone is in flash mode, you can check it when use flashtool.The solution is:

- Download FTF 4.3 from XDA web.

- Flash it to your phone by Flashtool ( newest version). Please check the mode when you connect phone to computer, if it is in flash mode, no need to press volume down.

P/S: DON'T use Sony PCC for updating. A lot of risks with that software.

And see the results. I succeeded with this way. Hope this help you.
[Xperia Z1 Q&A, Help & Troubleshooting] chivuletz:
Let it on charge for a few hours.. congratulations man... your phone is alive ;)
[Xperia Z1 Q&A, Help & Troubleshooting] vv91xv:

What have you done with your phone ? Its working ?? can you turn on the phone ?
[Xperia Z1 Q&A, Help & Troubleshooting] huzz:
Has anyone who was getting red led flashing managed to get it fixed? Flashtool recognizes my phone but after it prepares the files to flash it gives the window where it asks you to unplug and press the volume down button, nothing happens after that... Anyone got a suggestion?
[Xperia Z1 Q&A, Help & Troubleshooting] NeoPlex:
I have same issue... phone was updated to the last FW C6903_14.2.A.0.290_CE, update completed, after that phone was unplugged and now i can not start the phone.

No led under charger, no recognized by PC, SUS and fashtool. Any buttons combo doenst work to get him back. I can hear the faint whistling when I trying to turn it on. That's all.... :((
[Xperia Z1 Q&A, Help & Troubleshooting] Rekoil:
Are you all flashing using Flashtool v0.9.11.0 ?
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
I think they still flashing with v0.9.11. Can you believe it. And then asking why?
[Xperia Z1 Q&A, Help & Troubleshooting] NeoPlex:
0.9.13.0
[Xperia Z1 Q&A, Help & Troubleshooting] Rekoil:
I hope so, I keep thinking I've done something wrong, then I go back and check my work and there's literally nothing wrong with the file.
[Xperia Z1 Q&A, Help & Troubleshooting] huzz:
I am using the latest flashtool version. (0.9.13.0)
[Xperia Z1 Q&A, Help & Troubleshooting] Rekoil:
What options did you use? Did you clear cache? Are you by chance still in fastboot mode or something?

Press and hold the hard-reset button under the SIMcard flap for a while, then (with a USB cable connected to the computer) connect the USB cable while holding the volume down key, a blue (or green, can't remember) LED should come on.

EDIT: Sorry it's volume up and connect USB for the blue LED. (Fasboot mode).
[Xperia Z1 Q&A, Help & Troubleshooting] huzz:
I press the buttons and manage to force shutdown (3 vibrations) still after keeping the volume down button pressed and plugging in the phone it isn't detected in flash mode. Only thing I can think of is that it still needs charge. Does anyone know what the red light blinking means?

The problem is I cannot get into flash mode and as mentioned by gallardo below, flashtool says the same for my phone.
[Xperia Z1 Q&A, Help & Troubleshooting] gallardo5:
Now i have another problem. My phone is dead when unplugged, red led blinks when I connect to charger. It has been charging for more than 10 hours, but when i plug it to pc it recognises it as USB Input device. Flashtool says that "device is plugged with usb debugging off". Can I fix it somehow?
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
Your phone is ok, it's recognized, good sign. Try again, with calm, flashing the FTF. Pushing the volume down all the time and plug the usb in PC, let first windows install the drivers, check if is in flash mode, always keep pushing volume down, open flashtool, select firmware, wipe data, cache and appslog, unclikc everything else, flash, keep pushing the volume down until the green bar of flash do not show up, when you see first % of the bar, you can leave the phone alone.

So let it charge a bit more to be sure.
[Xperia Z1 Q&A, Help & Troubleshooting] huzz:
Thanks I guess that is what I am going to do. Leave it on charge the entire night. Coz getting into flash mode is the only problem the phone seems to be alive since it vibrates and everything perhaps just doesn't have enough power to get into flashmode.
[Xperia Z1 Q&A, Help & Troubleshooting] wezzel98765:
If you read all of my posts... i've tried SUS, ive tried flashtool... i have tried EVERYTHING.. phone was sent back to SOny today. Will probably have it back just after xmas
[Xperia Z1 Q&A, Help & Troubleshooting] NeoPlex:
just wipe all (appslog, cache,data)

I tried push reset button for a while -> realease reset button -> hold volume up and connect cable into the pc -> nothing.. no led
[Xperia Z1 Q&A, Help & Troubleshooting] Rekoil:
Can you get it into fastboot mode? Fastboot mode literally cannot fail due to software modification, since it is part of an early bootloader which is on a one-time-programmable (read-only) chip.

---------- Post added at 10:58 PM ---------- Previous post was at 10:54 PM ----------

You don't happen to have a Linux or OS X computer around do you? If so, try to connect the cable to that and repeat the procedure.
[Xperia Z1 Q&A, Help & Troubleshooting] huzz:
No the only thing I can manage is to get 3 vibrations. Red led lighting flashing. That is it. Flashtool recognizes but with debugging off.
[Xperia Z1 Q&A, Help & Troubleshooting] Rekoil:
Does it say "Device connected with USB debugging off"?
[Xperia Z1 Q&A, Help & Troubleshooting] huzz:
Yes
[Xperia Z1 Q&A, Help & Troubleshooting] Rekoil:
Ok, because that's what FlashTool shows for devices powered up in Android. Try holding power and volume up for like 10 seconds, then don't touch anything, hold volume up and connect the USB cable.
[Xperia Z1 Q&A, Help & Troubleshooting] huzz:
Thought the screen is blank. Let me see if adb gives any signs.

[UPDATE]

adb doesn't display anything under devices..
[Xperia Z1 Q&A, Help & Troubleshooting] Rekoil:
Not surprised, I mean if the phone was working as it should then you'd hear something while powering up. But it does mean that the phone isn't beyond repair. My guess is you're not turning it off correctly, and as a result SUS/PCC/Flashtool is not able to communicate with it correctly.

When you hold volume up and connect the USB cable, are you continuing to hold volume up for a while after inserting the USB cable? Have you tried doing this after pressing the hard reset button?

This is incredibly hard to debug via text.
[Xperia Z1 Q&A, Help & Troubleshooting] huzz:
Yes I have tried all the options. After the vibrations waiting / not waiting / keeping the button pressed / letting go of the button after connecting it / any other variations I cannot think of. I am hoping this is the only thing it is.

PS: I appreciate your help.
[Xperia Z1 Q&A, Help & Troubleshooting] Rekoil:
How did you install your drivers? Was it from this package? http://developer.sonymobile.com/downloads/drivers/xperia-z1-c6902-c6903-c6906-c6943-driver/

And yeah, everybody has been reporting strange battery-related things regarding the 4.3 update, definitely could be that. Are you charging using the USB cable and charger that came with your phone?

no I dont have...

yesterday I was updated phone on 257 without problem...
[Xperia Z1 Q&A, Help & Troubleshooting] huzz:
I don't actually remember Installing the drivers. I think I did from one of the packages posted online or windows did it on its own. Don't recall. I was running a stock deodex ROM posted in android development.

It' not good from Sony's point of view

I advise those that are having issues to possibly just send it to Sony

My device will be with Sony tomorrow. When I hear from them what they;ve done to rectify the issue I will update this thread
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
Yes, when you push the volume down and connect to pc, windows install drivers automatically. I guess you should leave the phone under charge all night with the wall stock charger. First thing tomorrow check if is turn off, push volume down and connect to the pc, if the pc will install the drivers, your are ok, flash it.

You flash the last ftf with version 0.9.11.0 flashtool ?
[Xperia Z1 Q&A, Help & Troubleshooting] gallardo5:
I flashed with 0.9.11.0, and now I'm trying with the newest one
[Xperia Z1 Q&A, Help & Troubleshooting] omar300:
well like most people here, my phone isnt turning on, neither going in flashboot mode so cant flash Ftf, neither is reacting to hard reset button, neither is charging.

so im doomed with no solution

also i sued 0.9.13.0 and i used 14.2.A.0.290 correct ftf for my model.

i have unbricked alot of devices of my own, this doesnt show any sign on life...

i would suggest no one update anymore until there are some clear instructions to avoid such debacle.

doubt sony will fix this for me, after all i have rooted the phone, if not unlocked the bootloader. this is still out of warranty.
[Xperia Z1 Q&A, Help & Troubleshooting] eclyptos:
The reason is because sometime someone missing something really stupid and happen what happen. Your phone can be resurrected 100%. But this process is for experts or you doing something wrong. Via text is impossible to advice anyone and help you without have in hands the phone. Try charge the phone even if no led show up and later connect the phone to the pc pushing volume down ALL THE TIME, see is your computer recognize the phone and if he install automatically the drivers, if so, you ready to repeat the process. If not see if there still any life. When you see if something happen from there we have to understand what to do.

Same deal.

Used latest flashtool and only flashed the 290 kernel and its really dead.
[Xperia Z1 Q&A, Help & Troubleshooting] mharckk:
try this have a .257 ftf ready, then flash it using flashtool. make sure youve charged atleast 1 hr.

how to:

1.connect your usb cable only (not including cp)

1. start flashtool>lightning icon>flash mode> select the .257 firmware (i know almost everybody knows this step)

2. wait for when it says connect your phone via flash mode

3.after that connect your phone then press volume up + powerbutton (hold for 10 seconds)

4. then immediately hold power button + volume down.

5. from here hope the computer will detect your phone.

anyway, tested this working in my XS when i was starting in flashing roms. so i think this will work also with z1.

Flash tool keeps showing it connecting and disconnecting.

I'll just continue leaving it plugged into the wall charger.
[Xperia Z1 Q&A, Help & Troubleshooting] mharckk:
does it not vibrate?make sure youve charge your cp, dont matter if its blinking or not.

well if still doesnt work, then the best option is bring it to sony service center.
[Xperia Z1 Q&A, Help & Troubleshooting] andymg350:
If flashtool shows your device connecting and disconnecting constantly hold vol up and power for a few secs and it should vibrate 3 times which means your phone was stuck in a loop and you have just powered it down.

Out of curiosity after reading through this has everyone updated to the latest flashtool version? And if you have did you run the driver install package from flashtool directory and install z1 drivers, fastboot drivers and flashmode drivers?

I've had this problem before, thinking it was dead no led, red led all that stuff, when I first had my phone and started playing around and unlocking boot loader flashing ROMs etc stay calm! with a little perseverance you will get through it just try not to panic

I did use the latest flash tool from the start.

So it was blinking red last night and now it's back to doing nothing.

I think pressing the hard reset button was a step backwards.

I did read elsewhere that red blinking means the battery is too low for kernel charging.

Please forgive me if this is a really stupid thing to say, but has anyone tried a USB jig yet? I know it saved a few Samsung devices from similar sounding situations. Not sure it will work for Sony though, just putting it out there.

This thread has scared me of messing about with my device, I would like to know the root cause of this issue and how to avoid it before I start mucking about with it
[Xperia Z1 Q&A, Help & Troubleshooting] huzz:
I think the root cause of this issue is insufficient battery. After the tft is flashed there is a considerable drop in battery level and basically there is no way to wake up the device if your battery isn't fully charged.
[Xperia Z1 Q&A, Help & Troubleshooting] NeoPlex:
I dont think so. I think that after last flashed phone stuck in bootloap, therefore LED dont gave ani color. After some time phone has been totally discharged, chip has been reseted and thanks of this LED showed red light under charger. This is my opinium.

BUT questions is, if this is a SOFT or HARD brick.. I waiting for results from user zeppelinrox. If zeppelinrox does not phone bring to life, so I think it is hardbrick (probably dead EEPROM)

I think you should go to the store when you brought it and said the phone do not turn on anymore, so go for replacement via warranty. I think they do not know what happen. Or keep trying, do not matter if the phone do not show led, vibrate or something else, the most important thing now is if your PC can recognize the Device in some way, with volume down or up, whatever.

So here is what uliwooly told me to do, keep holding the VOL up and power until something happens, then charge it for about 1 hour, then use Sony Update Service.

And I gotta say, it really took time for this "something" to happen, I remember holding it for about 2 to 5 minutes.

Hope people get Z1 working.

I just got another simple, but unpredictable idea.

Try rooting your device (I know that it will fail) using Kingo Android root as it keeps restarting the phone because it is failing.
