I found out that i was not using the Beta5 version which is the one indicated for the Xperia Z and now im facing a different problem,
The phone doesn't stay in flashmode for more than some 30 seconds, then it disconnects and boots normally and i still can't flash the phone.

Yes it is, it happens for all xperia models
Ll give you the idea
1. Install flashtool beta 5
2. Install Xperia Z flashmode and fastboot drivers from drivers folder of flashtool installation directory
3. Copy the ftf to firmwares folder
4. Don't connect the phone, now flash the ftf and wait till it prepares the files for flashing (believe me this WILL take a while)
5. Now when it asks to connect after preparing, switch off the device and connect by pressing the volume down button
6. Now it starts! Solved?
Press THANKS if I helped!

Thank you for that guide
I followed your steps but the same happens, phone disconnects from flashmode to boot normally. I even tried using a Windows 7 pc but same issue.
However, if I use SUS phone remains connected and the process runs well. If i connect with flashtool (or without any programme at all) it will disconnect after some seconds,

smash_07 install pc companion and go through the steps for doing a software repair it will install the drivers, as the drivers dont always install properly from the flashtool drivers folder even though it says there installed, once the s1 boot drivers have installed cancel the software repair and then open flashtool and go through the normal steps and you should find it'll start flashing the software for you, as I had problems like you until I did what I posted, also make sure there is no other sony apps running as that can stop the flash from starting.

Confused, it is normal that it gets disconnected after some time but it is so peculiar that it disconnects so fast! Try the solution posted by the other guy and share the solution, ll figure out another way if it fails
Ps: Before starting flashtool make sure that adb isn't running. Open task manager in windows, kill adb.exe if present and then open flashtool, follow the guide I posted earlier and when the part comes that the preparation of files is complete and when you connect your device, make sure that none of sony related apps are running (sus, pcc, emma). If they do, EXIT them first (closing them will minimise them to system tray so exit them from there). This also can be done before opening flashtool.

I did all you suggested but in the end i get always the same result, phone disconnects from flashboot shortly after connecting, eccept inside Sony Update Service or PC Companion.
I unistalled all the drivers, even Sony's apps a reinstalled PC companion to install the drivers again. I used another pc with Windows 7 32bits and I get the same behavior, disconnects from flashmode in about 30 seconds.
I'm starting to think that there's someting wrong with the phone itself, which i hope not.

Where do you see the percentage when flashing?
I made a tutorial on HOW TO FLASH STOCK ROMs WITH FLASHTOOL and I don't see the percentage. It justs tells me that flashing is complete.

The issue has changed now, the percentage was because i was not using the correct flashtool version for the the Z.
The problem now is the phone disconnecting from flashmode in about 30 secs after connecting and flashtool never gets to start flashing it,
EDIT: Changed the thread title to reflect the new issue now.

Have you installed the driver using the flashtool? Not talking about the PC companion driver?

I tried both ways, with the flashtool drivers and pc companion ones.

Am confused, 30 secs is more than enough to start the flashing process, are you saying that the flashing doesn't start in 30 secs? If so, that's why I told you not to connect the phone at start and after the preparation of files is complete and when it asks you to connect, try connecting and immediately the process should begin. Even if you have connected the device before, no probs. Flashtool don't need the phone till preparation of files is complete, so you disconnect whenever befor you want, the time where it pops a popup asking you to connect the device (shows an animation) is where you should properly conmect and leave it aside. It will and it should start immediately

Got the problem!
It was the firmware package that is corrupted. I tried using the UK .434 instead and it flashed with no problems or hickups. So the drivers and the phone were working well all along and the problem was where we less expected, in the firmware package.
I got the UK .350 firmware from here so there must be an error that has to be addressed with it.
Many thanks for your help

Glad you made it, cheers!

I found that running the 32 bit version of Flashtool solves the problem as well.

me too but my phone is TX, using flashtool 0.9.19.8

Hi all, if anyone is having trouble flashing with flash tool because usb debugging isn't enabled error then do this procedure.......
1. Dowload latest flash tool 0.9.18.8 and also version 0.6.6
2. Try use the latest version first to Flash the tft rom. NOTE: remember the file it has error flashing e.g on my experia sp file system.sin was not able to Flash bcoz usb debugging error (enable usb debugging and unknown sources) ALL THE REST of the files flashed ok!
3.try flash again the rom but this time tick system.sin (or error file) in flashtool to exclude it from flashing. Make sure all other files are included. Also tick all wipe caches options and flash rom without system.sin (or error file).
4. Flash procedure will work. Now disconnect phone and leave it off without restarting it.
5. Uninstall flashtool latest version 0.9.18.8 and install flashtool 0.6.6 old version and open it to Flash the same rom BUT THIS TIME only select the system.sin file (or error file) to be flashed and rest excluded. Make sure all wipe options in flashtool are enabled and Flash! THE FLASH WILL WORK WITHOUT USB DEBUGGING ERROR and your phone will be fixed!
Press thanks if it helped!

[Q] Help with root

Hi,
Just got my new ZR and it came with 10.3.1.A.0.244
I need to root, so I can restore my app's data from my old phone (Xperia SOLA) via Titanium.
I started by following this thread and doing as advised:
- install USB drivers (Z, A, fastboot and flashmode)
- change USB mode to MSC
- activate debug over USB
- install Flashtool (upgrade in my case)
- restart phone in flash mode
- use flashtool to flash XperiaZ_C660X_KernelOnly_10.3.A.0.423_Generic_NL.ftf
- flashtool says it succeeds, to remove cable and start phone
That's where it gets stuck! The phone doesn't wake up. I remove the battery, press the power button for a couple of seconds and it vibrates and ... nothing else. If I hook the phone into FlashTool, it says the phone is in flash mode.
I've tried flashing the XperiaZ_C660X_KernelOnly_10.3.1.A.0.244_BE.ftf, but nothing works.
I bring the phone back alive by using SUS, but I'm back where I started. I've done this 3 times, and redownloaded the FTF 2 times.
What am I doing wrong? I'm still on locked bootloader. The phone has less than 24 hours... hasn't seen water yet :cyclops:
Wanted to test a couple of things, before voiding my warranty!!
If anyone has any ideas/sugestions, I'd love to hear them!
Hajah

Dude, XZR is C550X, you're flashing C660X which is XZ's kernel...
Follow the instruction here for root in 4.1.2 -> http://forum.xda-developers.com/showthread.php?t=2384590
If you're on 4.2, you can try follow here but it seems still buggy -> http://forum.xda-developers.com/showthread.php?t=2387008

Hi,
I see now where I got mislead... (n00b)
As I see it, no valid method to get root on 4.2!
Can I flash 4.1.2 on my locked bootloader? And where do I find the correct ROM image for my C5503?
Thanks again!

Found it! It was hiding behind a spoiler box in the 4.2 thread
Hajah, the C5503 n00b

try using doomlord rooting kit download it and connect your phone to your computer install driver if you want start doomlord press any key to continue it will automaticaly restart when it has finished

Yes, you can flash any firmware without unlocking your bootloader.
You can get all 4.1 and 4.2 stock ROM from different region in this thread

You can try to root your 4.2 using the method, some reported to be successful.

is there a quick and easy method to check if the bootloader is unlocked or not?

You can use Flashtool to flash stock rom, doesn't matter if usb debug mode is on or off (only needed to install recovery or to root)
Download stock rom, install flashtool + drivers and follow screen instructions.. Good Luck! :good:

If you still can enter custom recovery, you only need flash rom and (with) suitable kernel.
If not, you need Flashtool.
- make sure you have the newest version of flashtool and driver
- connect your phone to pc.
- when computer show error about usb not recognized, go to computer management - device manager. Find something in universal serial bus controller list that have yellow triangle and exclamation mark. right click and remove it
- disconnect your phone then reboot your pc
- install flashtool and driver, reboot pc again
- connect your phone to pc. Now, it should detect your phone.
- do flashing procedure

[Q] Xperia SP Bootloop in Sony logo + not detecting in flashmode to flash stock rom

I've got a xperia sp, unlocked bootloader device. I've installed CWM recovery. Recently I tried to install CM 11 and I changed the update binary file since I couldn't flash the rom due to set_metadata error. ( A fix I found in a XDA Thread ). Now the device is on a boot loop at sony logo. I had this issue previously and I just flashed my stock rom using flashtools.
Now the issue is, when I connect my device to the pc while holding the volume down key, the green light ( indicating the device in flashmode ) comes up and it stays for few seconds and the device boots normally going into the boot loop.
I have installed the drivers for xperia, since I rooted and installed the cwm recovery on the same machine the day before. I prepared the ftf file and when flashtool prompted me to connect the device I connect. Windows does not indicate a device connecting with the usual sound.
I tried every possible way of connecting the device in flashmode but it doesn't stay for more than 5 seconds. The same for fastboot too.
any ideas on how I can recover my devce without giving it to a service center?
Thank you.

Firstly, power off the device if stuck in bootloop.
Take off your back case. Take a pen,pencil or similar object. Hold the small yellow button at the bottom of the device with the nib of pen or the object you are having. Hold that button until the device vibrates thrice
If you have flashtool.. Download stock ftf from http://forum.xda-developers.com/showthread.php?t=2311964 and place it in Flashtools>firmware. Connect your device in flashmode( Volume Down and connect). Click on the Lighting Button> Flashmode and flash. [ BACKUP YOUR INTERNAL MEMORY AS IT GETS FORMATTED]
But note that you will lost Root Access. You have to root your Xperia SP again. And if you have unlocked bootloader then it will remain unlocked. No need to unlock again.

The problem is that I tried doing that! when flash tool requests to connect the device in flash mode, I power off the device and while holding the volume down connect. But there is no sound from pc of connecting a device.! The device turns green for 5 seconds, then starts to boot again. I tried installing the drivers again but the drivers are already there!

Are you able to enter CWM ?
---------- Post added at 07:04 AM ---------- Previous post was at 06:52 AM ----------
Try this. [ I am not sure about this. I haven't tried this ]
Connect your Xperia SP with pc. And hold that small yellow rest button for 5-6 secs. It should connect your device in flashmode.

It just my opinion. If flashmode does not work why not try in fastboot? Just download any custom rom. Extract the zip file and flash it boot.img. Enter the recovery by pressing vol+. Install the custom rom. After finishing you can try back to flash the stock rom using flashtool.

This seemed to be a hardcore drivers problem. I can't pinpoint you to the right direction as I am not a Windows user (and also prolly lazy to reboot my laptop right now lol)
On your own computer
Open Device Management, and uninstall all related drivers of Xperia SP. These also includes flashmode and fastboot mode drivers. Then execute the "drivers" installer within Flashtool install directory (which is default C:\Flashtool). Then attempt to flash again.
Try on another computer.....
...to see if it works. But make sure to install the drivers first, as mentioned above. Attempt flashing again/
fastboot a CWM-ready kernel
You could also alternatively use a quicker flashing process, which is fastboot WIlliams kernel v7 (the kernel's .elf is in the zip). I can assure it only takes lesser than 4 seconds. For broader steps you may refer here: http://forum.xda-developers.com/showpost.php?p=56907083&postcount=3

Hi, I just tried this method and it worked. I switched from sony cable to samsung cable and it detected the device fine. I wonder what makes this issue. The cable works fine.

Firstly, power off the device if stuck in bootloop.
Take off your back case. Take a pen,pencil or similar object. Hold the small yellow button at the bottom of the device with the nib of pen or the object you are having. Hold that button until the device vibrates thrice
If you have flashtool.. Download stock ftf from http://forum.xda-developers.com/showthread.php?t=2311964 and place it in Flashtools>firmware. Connect your device in flashmode( Volume Down and connect). Click on the Lighting Button> Flashmode and flash. [ BACKUP YOUR INTERNAL MEMORY AS IT GETS FORMATTED]
But note that you will lost Root Access. You have to root your Xperia SP again. And if you have unlocked bootloader then it will remain unlocked. No need to unlock again.

The thing is for me
1) I cant see the small yellow button that you are talking about.
2) My device is nto connecting to the flashtool, it keeps on telling me to press the 'back button' -which my xperia sp c5303 does not have.
3) your volume down and connect does not do anything. Apparently there's supposed to be a green light as well and I dont see that.
This question is really to anybody knowledgable about this... Can you help?
I have Flashtool. And the stock firmware in the right place as well. But nothing else seems to be working.
My phone shows the Sony icon when I plug it in to teh computer and press the power button, otherwise when turn it on, it just shows a red light.

I think he means the reset button. It's more copper or gold than yellow.
2nd
Don't look for back button. In the SP, vol down is Flashmode, vol up is Fastboot.
3rd
Press the button before connecting USB, hold it and release when light becomes green.
4th
I would recommend the Sony program "Emma". Make sure you get the latest version. Earlier versions didn't support the SP.

one more thing, its says I need an unlocked bootloader but on some other threads where they were using flashtool they said that having an unlocked bootloader was bad and that it can severely damage your phone. Either way I cannot unlock my bootloader so it doesnt matter. I'll try it using Androxyde's Flashtool first and then yours if it does not work.

It didnt become green, and also there is no reset button, there is only a yellow bit of plastic in this little hole, and it says OFF. But I dont think that does anything.
I think I need some more specific instuctions and need to know where that button is.

Didn't read your bootloader is locked. Then forget Emma! It won't work.
The off button is the reset button.
Do the following.
When flashtool asks you to put your phone to flashmode:
- Unplug the phone
- Turn it off if it isn't off
- Press and hold the volume down button
- Keep holding it!!!
- Plug your phone to the PC. Don't usw usb 3 port.
- Light will turn green, flashing will start

Actually to use EMMA your bootloader has to be unlocked, but if you can't use flashtool or EMMA, you can try the original Sony PC Companion. Go to the repair phone section, identify phone, and it can help you to flash your stock firmware. From there you can restart flashing.of ROMs and all. Worked for me

This would work except for the fact that my phone's bricked. I deleted the system part of the phone using TWRP. So yh.
I have used the repair thing before though, when I deleted the download manager on my phone and literally could not download anything. So I can recommend that definitely.

Have you installed all the necessary drivers via FlashTool? All 3 of 'em i.e fastboot drivers, flashmode drivers and SP (huashan) drivers?
I know its a rudimentary question and you probably have but you'd be surprised how often people get stuck cause they haven't installed requisite drivers.
If the above fails, well you already seem to have TWRP installed so why don't you just boot into it and flash a ROM? Unless you really need to return to stock firmware for some reason, that's a viable solution to your problem.

I think the root is gone, that was part of the thing/whatever I did using TWRP to the system. So using any custom recovery is out of the picture anyway cos it wont work without root and then that's without the fact that I cant access the recoveries in the first place. Every time I try and turn my Xperia SP on, the illumination bar lights up red two or three times and that's it. All the time. Sometimes when connected to the PC it shows the Sony logo, in bootloop.
On flashtool, I made sure specifically to install the SP driver and the flashmode driver. I'm still trying though...

But coming back to what you said, I have a nandroid TWRP backup already. And it's of the stock OS. Is there some kind of shortcut that anybody knows to fixing my phone that's been bricked and currently has no firmware or recovery installed?

Why did you delete the system via Twrp? Also when you say you can't unlock your bootloader, does that mean you don't know how to or its not unlockable at all? Is your phone being detected in fastboot and is it showing up in Device Manager?
Well if your system's gone, root access is the least of your worries. On the bright side though, your phone's recoverable since as you have mentioned, its alteast showing the Sony splash screen occasionally.
You need to get Flashtool to detect your phone cause Sony PC Companion won't work since you don't have a working system and I read above that Emma needs an unlocked bootloader. Also if your bootloader's not unlockabke, you can't flash a custom recovery and what good's a nandroid backup when you don't have a recovery to restore it from?
If you can't get your phone recognized on your PC, get on someone else's, one preferably running 7 if you don't want to go through all the disable driver enforcement nonsense and install FlashTool, install drivers and flash stock firmware. Like I said, as long as you can see the Sony splashscreen, your phone ain't dead.

Me deleting TWRP was an accident, I dont know exactly how I did it, but I'd attributed it to wiping my system. Or by removing root, which I did somehow. I think removing root, kinda makes a custom recovery useless.
My phone's bootloader unlock permissions are set to no. So I cant unlock it.
And every time I try to flash a stock firmware .ftf file onto it, the phone is not recognised and I make sure to press the volume down button when I connect the wire to the phone.
And yeah, the SONY logo shows itself when my phone is charging. It's been like that for the whole time just on SONY. Also the illumination bar is red. But is it not supposed to turn orange and then green if it is fully charged.
And no, I have been able to flash a custom recovery without having unlocked my bootloader. It's how put TWRP on it in the first place- though I need to find it again. Hopefully, soon, Ill be able to install it and then flash my NANDROID backup onto it.

Xperia SP almost dead after flashing. Need help.

I flashed my Xperia SP with from Jellybeam to CM13 rom. I didn't create any backup, wiped clean everything including cache using twrp recovery. While the setup installed CM13 without any error but I downloaded the wrong gapps and the setup didn't accept those. So I chose to reboot the cell and since then it just stopped responding. Although it is showing the green led while plugged in via USB, it won't start in neither fastboot nor recovery mode.
I'm stuck here and have no idea what to do.
I tried installing PC companion, flashtools, SP flashtools, emma, everything. None of these detect my cell. I'm using Windows 10 (64 bit) and am at a dead end.
Any help would be appreciated.

UPDATE:
I managed to flash it with errors and now it's stuck in a SONY logo bootloop. Its starts, shows SONY logo for a while and then turns off again. Again it's not getting recognised by any flash tool, sony companion etc.
Help please.

Installed the driver and flashed it with a rom but it's still stuck on the SONY logo. One more thing, It's bootloader wasn't unlocked when I messed up at the beginning. What can I do to save my phone?

Whether I try to flash it or unlock, phone boots up before the process is completed. I'm completely stumped here.

Hi! Still have the problem? I faced the same two days ago when I tried to change the on on my SP. But finally I could save the Phone by searching a bit on the net. Pls tell me if matter is still on and I try to translate the steps to english.

Hey!
Sad to hear, but maybe (I hope) this method will help you. Basically what you will get is an original Xperia SP with 4.1 android as it came from the factory.
You will need:
1. Sony Mobile Flasher by Androxyde" version 0.9.18.6. Don't know if newer version came or better. You can find it here in forums. http://forum.xda-developers.com/showthread.php?t=2489955
2. The basic ROM "12.0.A.2.254".
The method that helped me:
SP turned off. Cable not connected.
Start Sony Mobile Flasher (Flashtool) , give administrator rights.
Top left cornet click on the bolt and choose flashmode, then in firmware selector you can find and select the downloaded ROMs and kernels. Choose the official 4.1 (12.0.A.2.254). Click falsh so it starts to proceed.
Then a windows appears called "wait for flashmode".
Now. Grab your turned off SP press volume down and connect the usb to pc. Keep holding volume down button till flashtool starts to upload the system. (Hopefully it will be fast enough, and phone will not turn on. For me it was)
After flashtool is finished you will see:
09:50:53 - INFO - Flashing finished.
09:50:53 - INFO - Please unplug and start your phone
09:50:53 - INFO - For flashtool, Unknown Sources and Debugging must be checked in phone settings
09:50:54 - INFO - Device connected in flash mode
Unplug and start the SP
If everything went as planned you have your phone back with stock 4.1 and 12.0.A.2.254 kernel.

Thanks a lot brother. At first it didn't work when I flashed it with the latest version of Flasher. Then I installed the exact version you mentioned (0.9.18.6) and phone didn't boot during the flashing and now it's back to normal with the default 4.1 stock.
Thanks a bunch, you're a life saver for me. :highfive:
