Help Rooting required

Hi,
I've got a I9301I with build KOT49H.I9301IXXSAPG5
Cannot root it:

• Kingroot crashes instantly with VerifyError exception
• Heimdall cannot retrieve PIT from phone in download mode

Heimdall log:

Code:

---

$ heimdall  print-pit --usb-log-level info --verbose
Heimdall v1.4.1

I was able to read the I8730 (already rooted) pit without problems using the same cable and usb port.

Any idea? did they close all backdoors so rooting isn't possible anymore?
