[Q] How to fix xperia z3 if the lower key button during flashmode can't be detected? - Xperia Z3 Q&A, Help & Troubleshooting

guys im in desperate need of help i've installed the drivers for xperia z3 via xperia flashtool drivers the flashtool v9.18.5 seems to fully recognize my phone on boot but as i access flashmode it recognizes my phone as device connected with usb debugging off and as i tried to followed the instruction given on this thread http://forum.xda-developers.com/crossdevice-dev/sony/xperia-z1-z2-z3-series-devices-drm-t2930672 for lollipop can't even bypassed the pop up waiting for flashmode devices screen with some keys to follow so im unable to flash the ftf for the lollipop fully and hoped to relock my bootloader and restore my lost drm keys. currently the only way i can update my phone is by using prf creator.

[Q] Flash Tools

So I purchased an Xperia Z3 on Amazon and when I received it it had italian firmware on it. I was planning on installing the stock rom with flashtools but was wondering if it was really just that easy. Are there any drawbacks to doing this? Should I just do it? Normally I wouldnt care but there are loads of carrier apps on it that I hate staring at when I'm flipping through the app drawer.
Easy mate loads of tutorials around but flashtool tells you step by step what to do anyway. Just flash a generic firmware for your model and problem solved. Only drawbacks are if you unlock the bootloader which you can't do accidently anyway. If you need to send your phone in for warranty purposes just put the Italian firmware back on it. Just make sure your battery has a decent charge before you do it
Thanks!!!! It seems so easy, I should've done it long ago.

Use debugging shouldn't matter in flashmode make sure the phone is.off and hold volume down while connecting the usb cable. Also make sure your drivers are installed
Have you actually tried to flash the FTF?
Jus go ahead and give it a try

[Q] Xperia Z3 D6603 Unlikely issue

whos experiencing what i am undergoing right now? like the volume down button cant be recognized while accessing flashmode using emma flashtool, androxyde flashtool, and sony pc companion eventhough you've installed the drivers from the flashtool still can't be recognized in flashmode. How did you guys fixed it? Did you guys bought a new xperia z3?
Hey man.
All you have to do is:
Install the newest Flashtool.
Install from drivers folder flashmode and z3 drivers.
Go into Devide Menager on windows.
Connect usb cable to z3 while pressing down key of volume.
It will be appear SOMC device.
Try to right click, properties and update driver. Choose u will find manually driver and choose from already installed.
You will probably have 2 licensed drivers SOMC and SEMC. One of this should works. For me it was SEMC.
GREEN LIGHT DOESN'T WORK, but it's not a problem, already running flashing and for a few minuts i will have 5.0 android on my z3.
Btw nice, that Sony doesn't know that POLAND is baltican country...

Z3 rebooting after 40 seconds in Flashmode

Hello!
My Sony Xperia Z3 (D6603) is rebooting by itself 40 seconds after entering Flashmode so I am unable to flash a Firmware
Does anybody know how to fix this Problem?
I have Firmware 23.0.1.A.5.77 with German T-Mobile Branding and a locked
Bootloader (I don't want to unlock it)
Thanks to everybody in advance
The reboot happens e.g. if no connection established. Drivers installed? Flashtool started to establish flash mode connection?
I installed the drivers from Flashtool
I didn't Start flashing progress
Could that be the cause ?
