Did you install the fastboot, flashmode and xperia drivers from the drivers folder in the flashtool installation location?

If yes, then make sure you release the volume up key as soon as the led glows blue.

Hello I'm stock rom 6.1.1.B.1.54 locked bootloader having some things unclear about this:
1. Can I flash custom ROMs wth locked bootloader? If not, what happens if I try to? Do I brickwall my phone? Is it recoverable?
2. Can I still flash other stock ROM (for example .75) with locked bootloader?
3. What's the difference between flashing custom ROM via CWM and via Flashtool?
4. Do I always before flashing new ROM have to clear data? Do this wipe all installed apps and settings?
5. If flashing new rom wipes everything, will I be able to restore all apps&settings from full Titanium backup?

Sorry for late reply :angel:
1. It depends upon the ROM you flashing.. Some ROMS need custom kernel i.e bootloader unlocked and some can run on stock kernel.. So check the ROM requirements before you flash it... If u flash ROM that requires unlocked bootloader and you flash it on locked bootloader you will end in a bootloop
2. Stock ROMS (stock based ROMS) can be flashed on locked bootloader
3.Flashtool will flash Orignal firmware (Stock firmware from sony) i.e ftf file... And through CWM you can flash ROMS i.e *.zip files
4. Yes it is recommended to clear data (it will delete all apps and settings)... But also check ROM installation procedure some may not require to clear data. If you are flashing stock firmware (ftf file) using flashtool you can uncheck wipe data to preserve you data.
5. Yes you can use titanium backup to backup and restore apps anytime on any ROM or firmware :)
