Hmm, what firmware version do you have on your F400k? 10A, 10B, newer?

10L

Interesting. I was unaware of that version. It's evidently been patched. All root methods worked up to and including 12b (ioroot, towelroot, purpledrake, stumproot).

If you've tried all the above, it appears you're out of luck to root 10L. However, the great fortune with LG (for now) is that you can go backward in firmware version and root. So if it comes to that, grab yourself some LG Flash Tools, any tot which predates 10L and flash via download mode.
