Xperia U does not fast boot

I have installed the correct drivers from C:\Flashtool\drivers.
I then connect the USB cable into my PC, hold the volume up button and connect my phone to it, but it just starts charging.
I have used the search function, but it was of no help.
Did you unlock the bootloader ? You cant get fastboot access without unlocking the bootloader
Hope it helps !
Cheers
Since you had a doubt, I thought Id just clarify, Fastboot isnt the only way to flash Kernels. We can also do it via Flashtool and CWM Only thing is, if the kernel we flash isnt Sony-signed (ie, its not released by Sony themselves and unmodified) only an unlocked bootloader device can run that kernel
Fast boot does work without an unlocked boot loader. (At the least, the phone does connect in Fast boot.)
Was the phone off when you attempted to connect it (in fast boot )?

need help Nexus 6 on Bootloop, bootloader locked, unlock oem off, debug usb off

Hello im new here and i need help, my nexus 6 is on a bootloop after i tried to get it back to stock kernel, rom, and recovery mode. ive tried factory reset, and also deleting the cache but nothing, i've tried looking for instructions on how to flash the rom back in the nexus but all of them says to turn on usb debug and to also turn on unlock oem but i cant since its on a bootloop . i took it to att but they said they couldn't do anything and that their is possible aways to unlock bootloader without having to turn on usb debug and unlock oem
can someone please help me thank you in advance
Unfortunately, you appear to be out of luck. There isn't any way posted that would allow for unlocking of the bootloader to allow you to flash the factory img files without enabling it in the Developer Settings. Without that, you're stuck.
isn't there like a back door system where i can just throw in a recovery img or a rom so it can install it, or is it done as in impossible to do anything with it
Not without the bootloader being unlocked.
and there is no way to get bootloader unlock without debug usb so it completely impossible to fix it
well i'm done for , but thank you for the help
