One day i use reset button under the back cover to reset my phone when it jam.
After that phone doesnt work.
When i want power on, I can see only on the screen logo SONY and after that grey big settings logo in triangle and blue loading bar below.

You said you used 3 different versions of Flashtool.
Was any of them v0.9.18.5?

When that happens, are you on stock ROM?

yes. I had the newest rom updated by pc companion
Somewhere i read that I should wait until adnroid will reapir itself but I wait almost 12 h and nothing happen..
I think that phone is freezing on this screen because, if I unplug phone, diode red is still light on, despite loading bar is still moving

The part that concerns me is that toryyour phone is not responding in my experience that's a horrible sign and means that your device CB is damages beyond software meaning you will need you warranty.

Install Sony Update Service (SUS) and repair ur XSP
EDIT: I dont see any error in Flashtool. Data need time for flash.
1. Did u put the conector USB out of ur phone b4 finish the process maybe? Dont rush with this.
2. Install LATEST version of flashtool, try again to flash the firmware and wait till it finish.
3. Process btw Flashtool and PC Companion have to be completely closed. I mean COMPLETELY coz sometimes we start to flash having PC Companion running or running in task bar.
4. If u still stucked, close all process and use SUS :thumbup:

Restore the system. Use Sony PC Companion. And when you install, root and cwm.
Saludos.
EDIT:
When you install the drivers, it must be in usb debugging mode. Delete in windows system administration and connects to your pc othertime, but as you can't enter the system, you can't do it.
The restoration process is long. Pc Companion download the rom and then is installed. Make sure the phone has at least 30% battery (for internet download speed of 10mb), more is better. If you are in bootloop when you recharge or if you can't recharge, don't waste battery, located where is the option in PC Companion and when you have controlled, do it.
Good Luck.

Forget about PC Companion.
First totally disable PC Companion and then try with Flashtool again. I mean While using Flashtool PC Companion will b disabled in ur PC. Try it..
If u have C5302 Firmware means flash that.. Its very very easy bro. Dont know what happens with u .. try again the way i told
Guys problem solved
Did a factory reset and kept for charging for 1 hour
Fone restrtd automaticaly.
Thanks
To get it to C5302, just edit build.prop :wink:

[Q]Flashmode disconnects every minute

Hi,
My Xperia Z1 (C6903) (A.0.757) is being weird with USB connection to the computer. I shutdown my phone and put it in flash mode, then went to grab some FTF files online. When I looked at my phone again, it was at the home screen. So I shut it down again and held the cable to the phone port, but in about a minute or 2 disconnects and reboots into the OS. The weird part is the phone never disconnects in the OS.
Code:

I switched the charger cables and it did the same with flashmode. I switched ports on my computer and I still have the same problem.
Is my USB port damaged? Does flashmode have auto reboot when idling?
I'm afraid it'll disconnect while flashing, that would be death sentence to my phone.
Did it again and I got this:

Notice how it disconnects from flash mode exactly 1 minute.

Have you actually tried flashing something?

No. I was afraid that while flashing it'll cut off and then my phone is unusable. But based off this1 minute cut off time on flashmode, do you still recommend flashing?
This is a new Z1, so I'm not sure if its a defective port or not.
set up the flashing files
wait until flashtool tells you to connect, then connect, it will be fine
It was the same for me. It disconnect after a while. Don't know how long it takes though.
So I prepare the files and w8 for the prompt to connect the phone. That works for me anyway.

Which version flashtool are you using?
I had this issue on an older version.
back then i basically just keep holding the vol down button and proceed flashing.
annoying to do but that was the only way for me.
Didnt have this anymore with the latest version.

[Q] Hard bricked?

Hi,
I had unlocked my bootloader a few months ago to root the phone. I had taken a backup of the TA partition.
Today I locked my bootloader, and restored the backup of the TA partition I had made.
It doesn't turn on anymore. When I plug it in to charge, the led keeps flashing red.
When I plug it into my computer, its detected in flashmode. Sony PC Companian recognizances the phone.
I have tried flashing the stock Sony ROM using the Flashtool, but i always get an error.

I think so, it said the flash was successful. How can I check?
Did you have a original kernel on your phone then you locked the bootloader?

dial *#*#7378423#*#* on phone. service menu will open. go to service tests and scroll down to security.
there you will see 9 keys with key OK active written in bracket. if all keys are ok n active then relocking was successful otherwise not.
Also these keys are unique to each phone so you cant get those anywhere.

Yes I have. But I get errors:
11/036/2015 01:36:39 - ERROR - Processing of loader.sin finished with errors.
11/036/2015 01:36:39 - INFO - Ending flash session
11/036/2015 01:36:39 - ERROR - Error in processHeader : 22 : The device does not recognize the command.
11/036/2015 01:36:39 - ERROR - Error flashing. Aborted
Make sure the drivers are installed correctly and working.
Check the device manager so that you dont have the yellow exclamation mark on it.
If all is ok there, maybe the phone dont start into flashmode correctly.
Have tried to hold volume down while connecting the usb?

Check if the bootloader is actually locked; press the bootloader button in Flashtool, it'll say unlock if it's currently locked (as you know). Either way, try flashing just the kernel: a .img through fastboot if bootloader is still unlocked, or a kernel FTF from the forum if it's locked. Make sure the cable has no loose contact - unlikely that this is the culprit, but it doesn't hurt to be sure. From what I understand, messing up the TA partition would render your phone completely unbootable, fastboot/flashmode included, so it doesn't look like that's the case. However, this is the first time I'm seeing a device "not recognize" a command so...
To summarize: probably not hard-bricked, but no idea if it's fixable. Be prepared to visit the service center. This is all I could think of. Good luck.

So I took my phone to the Sony Service Center. They say that they'll fix it within 10 days, and the estimated cost is RS. 0; but they'll give me exact details tomorrow.
So how did it go, did they fix your phone free of charge?

Ok. I think it is advised on Flashtool page on xda that for all Z series phone, we should use version 9.13 because of some bootbundle files in the firmware. u can give it a try or buy new z2 or z3

Hello, can you fix your problem? Well, I have the same problem with my xperia ZR but I could flash my device by removing the battery then keeping pressing the "volume down" (until the end of the process) and connecting the USB, try and tell me how it went.

Cannot install firmwares for Xperia Z2 by using both Flashtool or Sony Companion :(

Hi everyone,
I was running facebook app on my phone, the app had stopped, then com.google.gapps stopped, then many notifications about stopping other apps appeared.
I tried to restart my phone but it stuck at the first step (Only "SONY" and "Xperia" on the screen). So I couldn't start my phone.
I tried to reinstall firmware for it.
Using Sony Companion, but it stuck on this step:
- Make sure your device is disconnected
- Turn off your device
- Press and hold the volume down key
- Connect the device to the computer...
- Wait until.....
I did following the instruction but my device cannot be detected.
Then I tried flashtool, but it stuck on this step:
07/042/2018 10:42:16 - INFO - Selected Bundle for Sony Xperia Z2 (SO-03F). FW release : 23.1.B.1.197. Customization : NTT DoCoMo JP
07/042/2018 10:42:16 - INFO - Preparing files for flashing
07/042/2018 10:42:38 - INFO - Please connect your device into flashmode.
07/042/2018 10:42:39 - INFO - Opening device for R/W
07/042/2018 10:42:39 - INFO - Reading device information
It looks like a serious problem. Anyone can help me, please!
Thanks so much!
