The problem.
When I boot the device it just stays at the Sony screen and does not progress any further. I am still able to turn off the device by holding the power button and the volume up button, I can reset it by holding the button longer waiting for the vibration, and I can hard reset by waiting till the three vibrations.
What I was doing up to the point it happened.
I was trying to get a custom ROM on my device, I had it previously rooted so I thought I would go further. I installed CWM on my phone I wiped data, cache, and dalvick then I went to install the ROM from SD card. During the attempt at installation I got some symlink errors with a status of 7. Not sure what to do turned off the device when I decided to put back its previous I turned it back on and arrived at the problem.
What I have done to try and fix it.
I have done the soft and hard resets, I tried using the PC companions repair tool. When it asks me to turn the device off hold down the power button then plug in the device nothing happens(I have tried this several times.) I downloaded the flashtool and the correct ftf and tried using that, but it doesn't detect my device when I hold down the volume button and plug it in. So it seems that the flashboot is not working on my phone.
Any suggestions on what to try would be much appreciated and thanks in advanced.

You probably didn't install the ADB drivers. Install them from the Flashtool folder (use the ones for TX) and then try flashing your stock FTF again. Remember to put the device into Flashmode.
Basically what happened was that while flashing your ROM the script that flashes everything deletes everything from the /system partition, then you got an error and the installation was incomplete, therefore there is no proper system to boot into. You could have easily avoided what happened by flashing a different ROM had you not powered off.

Thank you for response, I went and used the Flashtool-driver.exe and installed the Flashmode drivers, Fastboot drivers and the TX drivers. But it does not seem to have changed anything. To enter flash mode on the phone one has to hold down the volume down button while plugging the phone into the usb when it is powered off, right? Flash tool just sits at the instruction animation titled Wait for Flashmode. When I try to enter flashmode I do not get a response from either the program or the phone. Any more suggestions would be welcomed.
Thank you for taking the time to help.

Yes, that is how you enter flashmode. Turn off phone, and keep volume down button pressed while you connect the USB cable; the LED light should turn on with a green light. If you're phone is not entering Flashmode, then you might have a faulty USB cable, or there might be problems with your USB ports, either on your computer or your phone (try with different cables/computers).
Also, check your Device Manager (while phone is connected) to make sure the drivers are properly installed. If you have Windows 8, you should have had to turn of Driver Signature Checking in order for the drivers to install properly.

Yeah I turned off the Driver signature checking on my computer when I did it. I'll go buy a new cable and try a friends windows 7 computer. Hopefully there is nothing wrong with the USB port in my phone. Thank you for your help I'll let you know how it goes.
Thank you everybody for your support. My phone is now working. After my phones battery died I was able to get it charging, when it had enough energy it booted itself to the Sony screen so I turned it off and grabbed my new micro USB cable and was able to get it into flash mode. Everything is now working great. I wish a special thanks to Antiga Prime for taking the time to help me.
I INstalled a custom rom with Unlocked bootloader and after it was finished it just stuck in black screen... nothing happens the only thing happens is when i press power button and volume up vibrates and then nothing... no led's no charging nothing... please help
Is it detected with Flashtool?
@lexykon : i think since ur device responds, its not a total hardbrick. Flashing an FTF using flashtool should help

no it says no device connected
You have to push Hard reset button (red button just near the SIM card) until phone vibrates 3 times. Then you push volume down button and then connect PC microUSB cable into the correct connector on your Z1.
Flashtool should see your phone. Then you can flash with flashtool back to your previous (stock ?) ROM.

Strange. Did you connect the usb cable to your phone AND maintain volume down button?
Because USB debugging OFF is only when your phone has started Android. When in Flashmode Android is not started.
So after pushing red hard power off button and phone vibrates 3times (it's important it vibrates 3 times) :
- close and restart Flashtool on your computer,
- choose Flash button (strike icon), choose the FTF of the stock firmware then validate and then check 'Flashmode' then OK, it will work few seconds and bring you a new screen explaining you how to get into flash mode with a phone and cable in a Window,
- take your USB cable in left hand,
- push down volume button with your right hand
- connect your cable in micro USB port AND maintain volume down for a few seconds
I decomposed the steps because it is important not to wait too long when connecting cable onto your device and launching Flashtool (that's why I prefer to launch it before, as described above), because if the phone detects current in its usb port, it starts system. It is important to be ready and having Flashtool launched BEFORE plugging the cable.
Send the results.

That's quite wierd. The fact that phone's LED becomes red is a good sign, i.e. going to flashmode.
IS it Flashtool saying the phone is in USB debugging ? If not, you can then flash after the LED ran red with flashtool.
Flashtool may say it's USB debugging OFF if Android is booted.
If in flashmode, Flashtool should say :
03/043/2015 15:43:18 - INFO - Device connected in flash mode
And then you can flash...

Have you tried fastboot? Volume up while plugging cable.
Perhaps you can flash a boot.img from there and use recovery at least.
This is what happens to my phone when the kernel fails to flash, usually after restoring a nandroid.

Ok you shouldn't have that in your flashtool log.
Without the phone connected to the PC, you should have the following message, especially "Please connect your device into flashmode" :
03/049/2015 16:49:48 - INFO - Selected Bundle for Sony Xperia Z1 (C6903). FW release : 14.4.A.0.108. Customization : Generic FR 1276-5833_R5C
03/049/2015 16:49:48 - INFO - Preparing files for flashing
03/050/2015 16:50:49 - INFO - Please connect your device into flashmode.
From my point of view, it doesn't seem your phone is powered off.
Then to Power Off hard press the red button near sim card, just above the chrome power button until phone vibrates 3 times :

Ok dude. Sorry but I can't help you anymore. Maybe advanced developpers could. My knowledge on flashing Z1 is 2 days old only
FYI, my LED is blinking 1 time red and 1 time green very quickly when I power on my Z1 in flashmode. Nothing on screen, but Flashtool detects my device in Flashmode.
Maybe, as proposed by markuz85, you should try Fastboot mode (volume up instead of volume down)... but I never tried this and I won't be helpful on that.
Good luck and tell us if you have got something.

I went to Sony and played stupid... so they will replace it with my warranty thanks btw guys really appreaciate your help
When I look at your screenshot I think "have you pressed the left button at the flashtool before you connect the device?" only after that you can select the flashmode at this tool.
I used FlashTool to flash Sony Z3+ E6553 and now phone cannot power on at all. When I plug in to PC, PC can detect but flashtool cannot flash anymore. The phone was working fine, only has phone lock. Please help revise the phone. Thanks.

Are you sure that your battery is charged?
Try this: press and hold power and volume up button for 10 seconds and see does the phone vibrate.If vibrate flash again via flashtool.,he should works.

Battery was fully charged and I've tried that but phone does not response at all to flashtool. When plug in to PC, in device manager under USB controllers, it sees it as SOMC Flash Drive. I think the phone boot is dead.

Thanks for your help...The phone was flashed successfully with flash tool with flash file E6553_28.0.A.4.8. After flash done, phone was dead, cannot power on anymore. Now when I tried to flash it again, volume down, insert USB the flashtool show as: Device detected with USB debugging off. It doesn't go to flash mode anymore. I took the back cover off, remove battery connector flex cable and connect it back and try flashing many times but flashtool will not detect phone in flash mode..PC can detect phone because it makes connecting sound on PC but detects as what mode I don't know. In device manager, it doesn't show any device in com port but it shows SOMC Flash Device in USB controllers. I tried to press volume up + power but nothing happened. Once again thanks for your help.

did you try this ???
look here
http://sony.yt/topic/7324-english-t...oot-in-sony-xperia-z-c6602-c6603-c6606-c6616/
sorry to put a link from another forum.
Hey i'm not exactly sure what you mean by the description, but to enter flash mode you need to turn off the device - then hold down the volume-down key whilst inserting the usb. Keep holding down the volume-down key until you seen some green notification lights flash and you should be in flashmode and ready to flash a FTF. It should also say on flashtool that "Device has entered flashmode" or something like that.

Hello there... Any solution you found? I am stuck with my zuk z2 in same situation ?? any help ?
I have a similar problem.
What caused the black screen? -
History:
I booted to test mode at 2.5.033 ST, the phone got stucked at this menue there was no way to get out. TWRP Restore to Nandroid bougt only black screen after 2nd vibration and ZUK logo.
I fixed the Test mode bug, by flashing the ZUI 1.9.104 ST Stock ROM via QPST.
After the phone was "repaired" I unlocked the bootloader, installed TWRP, made a nandroid backup of fully stock ROM and restored a nandroid backup from before the test mode problem.
The nandroid restore was successful, I rebooted the phone and it was "dead". Black screen, only rebooting (perioldy vibrating) there was no end, until the battery was empty.
I got no luck to reach any mode with tricky button pressing (vol+ pwr; vol- pwr; vol+ vol- pwr; usb in vol-) nor Windows detecting the phone. That's why I decided to remove the back glass cover, to got access to the battery.
Now I'm able to get the phone detected by my PC.
What I did: disconnect the battery, connect the phone to my computer, pressed the vol- button and connect the battery.
This made my PC able to detect the phone, but no I have an other problem. Windows only detects the phone as "unknown usb device (device descriptor request failed)". I don't know any way to install the driver....
Maybe anyone is able to help me or has any tip?
Thanks!
Cheers,

What id shown in unknown device.
Like ven_9102&dev_1234
Maybe with editing quallcom drivers for your device id, you can still install it.
and if luck qpst can recognize it as qualcomm debug mod

Now I'm able to get the phone detected by my PC.
What I did: disconnect the battery, connect the phone to my computer, pressed the vol- button and connect the battery.
This made my PC able to detect the phone, but no I have an other problem. Windows only detects the phone as "unknown usb device (device descriptor request failed)". I don't know any way to install the driver....
Maybe anyone is able to help me or has any tip?
Thanks!
Cheers,

Alright bro, there is one method you can try.
http://zukfans.eu/community/threads/howto-flash-a-stock-zui-rom-zuk-z2-pro-z2121-only.57/
I assume your phone is a brick now. The only method you can use is the 9008 unbrick mode. (AKA QBST)
There are a few things you need to prepare before you save ur phone. U need to download the require application that the website provided above, after you set everything up,
make sure you download the latest 2.5 QBST rom,
http://bbs.lenovomobile.cn/z2pro/t554654/
Because ur phone wont be able to enter 9008 through software, thus u need to do the following.
1. Load the content XML fille,
2.Turn off your phone. After it's fully shutdown
3. press and hold the volume up button for 3 seconds
4. press power button while hold the volume up (press it for 0.5second and keep holding it)
5. after 0.5 seconds, plug in the usb right away
6. the QFIL tool should appear the Qualcomm usb QD loader
7. the download button should turn blue
8. flash it and wait for reboot

Thanks for your tip.
I followed your described procedure, but the phone will not be recocnized by the PC.
1st: I loaded QFIL XML file. (By the way this tut is made by me)
2nd: I disconnected the battery (The phone can't be turned off normally!)
3rd, 4th, 5th
6th: nothing happend!
7th: "-"
8th: "-"
The only way the phone will detected by the PC:
1st: disconnect battery
2nd: plug in USB (PC and Phone)
3rd: press VOL+ or VOL- or PWR button (doesn't matter which one)
4th: connect battery
5th: detected as "unknown usb device (device descriptor request failed)"

Yes, I did exactly you described. Sorry but this isn't working.
I don't know what I should do. Even a repair shop couldn't fix it.
Maybe I need to do this:

But I don't want to destroy my PC (3000 bugs)

I will report the result.
OK. I made the deepflash cable.
After using it there is no difference between pressing one of the button combinations I recently mentioned (VOL+ or VOL- or PWR).
The phone will be detected as Unknown device. After intalling my modified driver to match the unknown ID, QFIL don't detect the COM Port.
Hello had the same problem, only with the difference that my battery was not completely discharged.
What has helped:
1 Start QFIL Tool
2 Press the volume +
3 Connect the original cable to the PC
4 QFIL Tool recognized the phone and I could play an original Rome.

Ps. Is now the battery cover (glass) broken?
No, I used a hairdryer, a razorblade, plastic tool and a suction cup to lift the backcover glass.
The glass is fully intact no damages.
You have good nerves. I would not have expected that.
But in the end, it does not matter if it does not start anymore.
Thank you again for your great instructions for playing and rooting the mobile phone.
I hope you get your phone back.

Good and bad news
The guy unbricked the phone successfully, I received it today.
Now I have an other problem:
The phone is very very slow and laggy now.
The problem occurs everywere, Recovery, boot (the bootlogo laggs), booted System, also the test mode laggs now
Furthermore the sceen flickers sometimes and at the right side the sceen is mirrored sometimes.
Did anyone has an idea?
What I did today:
reflash through qfil
1.9.104_ST
2.3.044_ST
ZUI_2.5.335_ST
Hi m_atze, I am exactly in the same situation as You. After using deep flash cable method, I got "unknown usb device (device descriptor request failed)". Could You tell me what was the solution to unbrick the phone?
