No, the problem is that you have not unlocked the bootloader yet.
Google sony unlock bootloader and follow the instructions.
But if you are flashing a complete stock kernel then you can flash a FTF for your phone and exclude everything except kernel. Use flashtool to do this not recovery

Installed sdk. Plug the phone in nothing pop up, for me to select the driver folder, is it because I install the flashtool with us driver already?

I hope you back up your TA partition before you unlock your bootloader.
unlocking the bootloader will break your stock camera.
Just a friendly reminder =)

Can anyone help me or have had this error?

You are trying to flash a kernel on a locked bootloader..you can unlock it and flash the kernel but since you are a noob I would suggest you to downgrade back to 4.1 and root your phone using doomlord's method for locked bootloaders and then install a 4.3 custom rom

Don't try to apply things blindly to your phone, hoping for root. Might end up with a brick. . There's no exploit found in newest firmware to root it while in locked bootloader yet. You can go thorough this index to see what it means and other relevant info about our SP: http://forum.xda-developers.com/showthread.php?t=2618222

Happy rooting!
Edit: corrected the link

Can someone please help me as well.. I have an Xperia SP currently running 4.1.2 rooted, bootloader locked.
My aim is to upgrade to 4.3.3 and root, for which i will have to unlock the bootloader. To do so I need a TA partition Backup, for which again, root is required.
So, my question is that is it okay if I take a TA Backup now [in 4.1.2] and then upgrade OTA and unlock bootloader, root and then restore the 4.1.2 TA backup onto 4.3.3 in order to restore DRM keys and Relock the bootloader?
Has anyone done this?
is it safe?

try to boot your device in flashmode
install stock rom

If you failed to install a custom kernel is because you did not have unlocked your bootloader. You need a unlocked bootloader to flash boot.img, otherwise it will fail.
You got a black screen because you have not followed the right steps to install the ROM, some ROM needs to wipe everything (except sdcard) to work properly.

[Q] C6903 unable to flash images using fastboot

Dear all,
I want to update my C6903 to Anndroid Lollipop by flashing AOSP images after building them by following the instructions from Sony. But when I tried to flash them, below error occurred.
----------------------------
fastboot flash boot boot.img
sending 'boot' (8866 KB)...

I used flashtool(0.9.18.5) and EasyRootTool(v12.3) to flash the firmware(C6903_14.4.A.0.108_HK.ftf) and root the system, and used that flashtool to relock the bootloader.
When I tried to unlock the bootloader again, below errors occurred.

Check drivers then flash stock firmware again then check your bootloader status in service menu if unlocking is allowed use fastboot commands...
