Default Boot security error after trying to install Sling KK ROM

I followed the tutorial at http://forum.xda-developers.com/show....php?t=2762171 to install KK ROM on my OG E977, did EXACTLY like written, but then I got stuck at boot screen telling me I have a boot security error, probably due to a locked bootloader, I guess. I try to flash the stock KDZ firmware but KDZ updater offline fix tells me battery level is low when it's not, even when the battery was fully charged.

I can't switch off the phone manually, because it starts again and gets stuck at the LG logo screen with this message:

Secure booting Error!
Cause: boot certification verify

The only way to turn the phone off is with CWM touch recovery 6.0.4.8 by LGviet (after installing the Sling KK ROM or the F180 patch, I guess, because the recovery utility was CWM 6.0.4.7 non-touch installed by FreeGee after unlocking the bootloader.). And when I turn the phone off and plug the charger, the phone boots up by itself and gets stuck at boot security error screen.

I tried to send a CyanogenMod ROM via adb sideload, but it tells me the ROM is for E975, while the phone is a F180 model.

Could someone give me a help, please? Thanks in advance.

How can you boot into recovery once it's in Secure booting error?
Any how fix it using teeny bin repair, it's easy fix.

Or, just as an alternative, find a KDZ that works with the regular KDZ Updater (filesize up to 1.17GB worked for me). This way, as opposed to the offline method with LG Support Tool, you won't get a low battery error, even if the battery is completely dead. Had exactly the same problem myself, this was the solution I used.
Optimus G F180S, VDT V23 (KK 4.4.2)
Galaxy S5, rooted stock 4.4.2
Venue 8, rooted stock 4.4.2

To whom it may concern: STOP nagging about pressing the freakin' Thanks button!!! It is rude, stupid, and annoying as hell. I am not an idiot who needs a huge in-my-face reminder to press it, and I will press it when I feel thankful, not because you asked for it!
