[Q] Xperia Z3 UB recovery, how to access? - Xperia Z3 Q&A, Help & Troubleshooting

Hi,
I succesfully unlocked the bootloader of my xperia z3 (D6603) by following the "Sony Developer's Website" instructions and by previously making the TA partition BackUp.
Once done I was stucked into bootloop, with sony logo and no led at power up, or any way to access recovery or system. Luckily I managed to enter flashmode and flashed stock android 4.4 via flashtool.
I know that I can use the Giefroot exploit, but as i gain root and recovery, this last one either magically disappear (launching only the first time) or I'm no longer able to access it. Neither via fastboot, system or by physical keys.
I tried everything more or less (FOTAKernel, RecRoot and a Z2 recovery for hardware similarities).
What I have to do? I'm not able to find a solution, or probably, I'm too dumb to find it.
Sorry for this mix of ignorance and bad english.

Ok, the answer was "hold power botton press volume down key".
I didn't tought about the simplest key combination, the funny tring is that I use that key combination on my nexus. This thing of LB and UB and the lack of a proper recovery partition is a little tricky to me.
Sorry for the time waste

Restoring stock ROM

Apologies for dumb questions but I am really newbie with Sony phones (I know my way around HTCs though).
I have the Xperia Z3 Dual (D6633). After some reading, I've managed to unlock bootloader, installed TWRP recovery and rooted the phone.
My wife somehow locked the phone without memorizing password and the brightest idea I've had was to perform factory reset. Accidentally, I have managed to perform a full wipe, wiping everything except mSD card (I have experience with CWM recoveries but not with TWRP). I did not backup software before accidental wipe.
Phone obviously wont boot but I am having hard time to get to recovery as well, phone just hangs with TWRP recovery logo on the screen.
The first step I intend to perform is to try to re-flash recovery again a go from there.
My intention is to restore stock ROM using Flashtool and d6633_23.0.f.1.74_1288-7362_r8b_ru.ftf
I've read how to enter appropriate boot mode, however, I am not sure witch one to choose for Flashtool to work. BTW, is it possible to restore stock software using Sony PC Companion software?
Can anyone point me in a right direction? A simple guide to follow to in order to get out of this tough situation?
Download your desired firmware and install latest flash tool on your computer.
Copy the downloaded firmware on to the flash tool folder which can be found on your C drive.
Hold volume up and power together till your phone vibrates thrice (power shut down)
Now open flash tool, select flash mode and then your firmware. Now press start.. You will see animation there asking you to connect your device.
Hold your phone's "down volume button" and connect it to the computer. Flash tool will recognize the device and starts flashing. Wait for it to finish.
Boot your device and you are good to go!

Success! Thank you for your hand holding.
Order of steps to get the phone to flash mode was slightly different in my case though. When I pressed volume up and power key the device did not react. Repeating the same process with USB cable inserted worked. When pressing volume down the phone was tying to get to recovery but then it hanged there. In the end when Flashtool asked me to connect the phone, I've kept pressing volume down key with phone turned off and inserted USB cable and it got recognized and software got flashed in the end. BTW, Flashtool does't contain drivers for Z3 yet, therefore I've installed drivers for Z1 / Z2 in addition to flashmode and fastboot drivers.
Currently I am updating software trough Sony Update and then I will check if bootloader is still unlocked ant will try to get to recovery. If no luck I will reflash recovery.
Thank you again!
P.S. I've noticed that there are slightly different application included in this ROM. FTF file in these forums is a slightly different version that came with my phone originally. It might be useful to get more versions of FTFs for D6633 model uploaded...

Try below step's,
1. Turn off your Xperia Z3 and wait 5-7 seconds after screen turns off.
2. Power on your device and when the LED notification lights turn on press several times Volume Up or Volume down buttons.
3. At the end, your Xperia Z3 will be rebooted into recovery mode.
If you found this helpful, there's a thanks button, just press it
I don't think there's any stock recovery on Z3, what are you trying to do?
There is no stock recovery on xperia devices. (The Z3v has a very basic one but only wipes cache's)
You need to root and install a custom one.

My Xperia M2 doesn't boot to recovery mode

I unlocked the bootloader using the instructions from the Sony developer site. It worked, and then I flashed the recovery software using the flash tool, Emma, but when I press the buttons to boot in recovery mode, instead of this, my OS resets, like factory reset, or it doesn't boot, just vibrates. I don't know what to do. I want to try cyanogenmod and I want to flash it, but without recovery I can't, and it's possible to find on the Sony site the stock rom in case I want to come back to the stock OS? And something else. After the reset, the OS looks different. I have features that I didn't have before

You have to upgrade your bootloader via Emma and flash the recovery.img via fastboot.
Thank you. I flashed a TWRP recovery and it worked.

No notification led and illumination bar blinking after rebooting device. I tried combination of power button + volume up or power button + volume down. Used Titanium backup to reboot into recovery. Ran adb command to reboot into recovery all failed.
