Kernel version is june 24th and I have an Sm-G900W8 on Wind mobile. I've tried towelroot but it didn't work.

Okay back, food in hand.
You didn't ask for details, but no doubt you'd like to have them regardless.

There have been reports that a recent OTA update has patched CVE-2014-3153 (closed the towel root exploit).

You should be able to use Odin to revert to a stock firmware build date prior to June 3rd. Then towel root will work and your Knox flag should remain at 0x0.

It's not an issue per se with the S5, but do not attempt to downgrade to JB (pre 4.3) as Samsung set a qfuse to block that. With such an attempt tending to brick phones.

If I downgrade via Odin, will I risk bricking my phone? And is the samsung-updates site good for downloading firmware?

Any time you use Odin, you run a small risk of bricking a phone. You are writing critical system files and any glitch or power interruption could have dramatic consequences. But writing the correct stock firmware for your S5 /carrier doesn't add any extra or undue risk.

In the future Samsung might add a qfuse for this method. But as of today it works fine and quite a few people have done it successfully.
