Downgrading DOES NOT require unlocking bootloader, you can flash Amy 4.1-4.4 ftf with an locked bootloader, but it must be a stock ROM. For rooting, the only way to root a locked bootloader is to downgrade to 4.2, exploit, install XZDualRecovery and update to 4.4 using a rooted stock zip and stripped ftf.
