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.
Hi all,
I rooted my phone and unclocked bootloader.
My rom is a stock rom.
I managed to install CWM recovery using lg-optimus-4xhd-recovery-v1.0.apk but something happened.
I rebooted my phone in recovery mode and it is always locked to LG logo.
Pressing Volume up and power I can see normal android system recovery, wiping cache and factory reset don't work.
I haven't usb debugging enable so my computer can't see the phone connected with usb cable, and it's impossible for me flashing the phone with kdz rom methods.
What can I do?
Thx in advance for your answers
No one can help me?
Flashing with kdz results in "phone was not found", is there a way to resolve? I've tried with ubuntu, OS (adb) only see my phone if usb debugging is enabled and it isn't, and with a laptop running win8, installing LG drivers and so on, nothing works.
This is salvagable
If you can get the stock recovery mode, all is not lost, all of the important bits are still functioning.
Power down. Hold VolDn and insert the USB cable. If you get the Software Update screen with a green icon you CAN recover the phone. It may require a battle with Windows to get it to play nice, Windows and USB is always a hit or miss affair; but the phone is ok if that screen appears. Do not use the VolUP + Power LG Recovery mode, there isn't a known tool for that in the wild.
I don't normally run Windows and the couple of times I have booted it to do this it required some hassle and usually skipping the nice way since I had never installed the bundled LG Desktop stuff before things went wrong. So just do what I did, pick the Emergency mode that requires inputting the IMEI instead of letting it detect your phone and then let it fix things for you.

Many thanks for your answer, I resolved the problem late at night, yes, after a hard battle with windows.
I installed windows 7 32 bit, I tried a lot of Lg drivers, 3.8.1 maybe the best, after inserting the USB cable with SW Update screen some LG peripherals were recognized but the result in KDZ_FW_UPD was always "phone was not found", then I tried connecting USB cable with the Phone in Android recovery mode ( power & Vol up), and OS added a couple more peripherals, and attempting again with SW Upgrade mode worked.

hi
are you ready to disassemble your xperia?
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 to all,
I would like to install a custom ROM but unfortunately my phone doesn't want to enter in flash mode! Once switched off, I plug it to my computer while keeping vol down button pressed but instead of entering in flash mode, it displays the battery charging icon.
I hard reset the phone but the problem still remains. Any idea.
Thanks, have a nice day!
My guess is either the USB cable (did you use the OEM cable?) or the drivers (does windows recognize your phone?). Removing the SD card or first entering recovery were suggested earlier (http://forum.xda-developers.com/xperia-l/help/update-volume-connect-doesnt-t2613733). But more experiences Z3c owners may have better ideas...

Using flashtool:
Turn phone off completely.
Start flashtool, choose flashmode and choose which firmware you are going to use. Tick Exclude TA.. Click on flash.
It will start preparing the build and after a few seconds it will ask you to connect the phone.
Plug the phone in while holding volume down, as soon as flashtool starts doing something, you can let go.
If you don't know how to use flashtool then I urge caution, Sony's aren't like flashing a Samsung, it is actually possible to brick your phone with flashtool. There are lots of questions on 'how do I fix my phone?' in this Q&A thread from people who didn't read up on what they were doing.
Recommend you read bilboa1's great guide on what to do, starting with backing up your TA partition..
Thanks for your answers but I think the mini usb from my phone must be dead.
About Flashtool, I can't use it because I can't go into Flash mode! Moreover, my phone is not recognized by windows. I tried with several usb cables and computers when I plug it, I don't have any MTP or PTP choice, it can only charge..
On Windows 10, devices is not recognized and Window 7 see it as a 5880!
And I tried to remove SD and SIM cards..

If the USB lead was dead you wouldn't get the charging icon on your phone.
Have you installed the Sony drivers.
You also need to run exe in the Drivers folder within Flashtool, to make sure you have correct flashomde drivers available. Installing these drivers is very difficult in Windows 10 and it require restarting the machine in safe mode, and going into the advanced settings to disable driver signature checking, this how to video is for windows 8, but you'll get the idea
Have you installed ADB?
Sonys PC Companion should set you up with the correct connection to your PC
Have you tried other USB cables?

Yes, I've installed PC Companion, adb drivers but nothing appears when I use command "adb devices". I've also installed flashtools drivers but deactivating drivers signatures in Windows. But when I try to flash, flashtool ask me to turn my device in flash mode (switch off then volume down + power) but I can't do that.
I've tried several usb cables. Some are charging my devices, some are aren't but none of them allows me to data transfer!
I've also tried to force MTP or PTP usb transfer in developper option, it doesn't work more..

Do you have any warranty on your phone, you could be right that the usb socket is damaged somehow, but it's strange that you can still get a charge through it.
Your only chance at moving to a custom rom change is flashfire
This should let you flash a rom without recovery.
Edit: Flashmode is just holding down just - volume button, not volume+power
Obviously your chances of rescuing a failed install are going to almost zero without recovery and flashtool, so be very very careful about what you try and flash in flashfire. Read up completely that the rom you want to flash is going to work pushed on top of whatever you are running at the moment.
For anyone who might be interested, sometimes you have to try a USB 2.0 port or just a different port. I had the same problem while using a usb 3 port, switched to 2.0 worked like a charm.
Try to open the back of the phone and removing/unplugging the battery wait 5 seconds and then put it in again. Then try holding down the volume down button while you connect a usb cable.

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

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

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?
