Hi Guys,

I had been installed a CM 10 Stable with CWM on my LG G2 (D802). I've tried to flash a stock KitKat Rom for my phone, using this tutorial:
http://www.droidviews.com/android-4-...-install-twrp/

I was hoping, that i can easily make a backup with cwm, flash the zips and check the factory rom out. The process crashed (perhaps because I had cwm), and i was trying to reboot the phone into the recovery mode. But instead, the default factory reset gui from lg occurs and after a confirmation comes a screen with the message "boot certification verify, Secure booting error, Cause: boot certification error".

It seems, that my cwm recovery is also flashed with a new kernel. I can't get into the recovery and download-mode.

In the next step I have tried this:http://forum.xda-developers.com/show....php?t=2582142
and then: http://forum.xda-developers.com/show....php?t=2451696

The single steps passed without errors, but nothing changed.

Is there any other possibility to unbrick my phone?

Sorry for my english

Thanks for your answer, but the link won't help me. For this I need an opportunity to get into the download mode, but i can't

What do you get when power on ? Do you boot into fastboot.
