Yes you can, but you will have to unlock the bootloader, but its advisable to root first so you can back up your TA before unlocking the bootloader, its your choice.

Just follow the link in my signature to downgrade and root

Also, now your QUESTION has been ANSWERED I will ask the mods to move it to the QUESTION and ANSWER section for you

You need to downgrade to 4.2 not 4.3

Okay just downloaded XDA DevDB: 14.1.G.1.534 downgrade FTF and flash it via flashtool. This step right?
After this root via 360 and unlockbootloader and than flash tool?

Not sure but when im right, you can root your. 757 firmware direct(look @gregbradley 's signature^^)

But if want the old method, then look here.
1. Download a 4.2 firmware
2.flash the whole ftf via flashtool
3.download 360 root tool(when the Name is right?!)
4. Root it via root tool^^

I never mention using any root method or unlocking the bootloader

In fact if you are going to unlock your bootloader there is no need to downgrade (Unless you want to backup your TA, which is advisable)

There is no need to do any of this.
If you are going to unlock your bootloader and not backup your TA then
  • Unlock bootloader
  • Flash SuperSU.zip

If you want to backup TA (or not unlock your bootloader)
  • Flash 4.2 FTF
  • Instal dual recovery
  • Flash a pre rooted 4.4 ROM
  • DO NOT USE ANY ROOT TOOLS (360, KINGO, VROOT, BIN4RY ETC)
  • NO NEED TO UNLOCK THE BOOT
