Root issues with LG Optimus G

[Stranyer]

I'm having issues with a LG Optimus G. I can't access Recovery or Bootloader. I can't even root it. When I use Root Checker, it says something it's wrong with the actual root.

All I wanna do, it's to install a custom ROM. But that seems impossible since I can't even get into recovery. I installed a KDZ but even then it won't work.

Download Mode, seems to be working. I tried rooting with the bat file, but nothing, it won't work!

I followed the Unbrick Tutorial, but nothing.

Any ideas?

Thanks

I used this Root on E975 with Stock 4.4.2 and it worked.
There is also a detailed description how to do it right.

You can unlock the Bootloader with FreeGee after you've rooted the device.
Then i would recommend you flash TRWP 2.8.7.0

P.s.
But you also can try towelroot or maybe King Root but i suggest the first Methode.

Thanks! King Root did work! Now it's rooted, still I can't install recovery I tried with FreeGee but it won't work it says "Perfoming action" for about an hour. Also tried with Rom Mananger but nothing.. it won't install it.

I keep getting the error "Secure Booting Error! Cause : boot certification verify" each time I tried to boot into recovery.

Maybe re-flash the last original KDZ file for your device first and then do the common steps -> Root -> Unlock Bootloader -> Flash Custom Recovery

You can Boot into download mode by "Hold VolUp + VolDn and put in the Charger cable connected with your Computer"

Then you can try the Original LG Software to "Reset" the device or use the LG Flash Tool 2014 to offline Flash a KDZ file.

KDZ for you device you can get here or use the Original LG Firmware tool to download for your device.

Get Sure you backup all the data you need before, becasue this Method will "clean" your device completly!

Edit:
Get sure you use the last USB Drivers, i've used the LGMobileDriver_WHQL_Ver_4.0.4.exe
