Help Me My Device is Stuck

Hello there !!
I have LG F 180L (Korean Variant) with custom rom Sling 3.3 given here.
I tried to install a rom on it usind CWM recovery but my device stucked into boot loop.
It says
"Secure Booting Error"
"Cause: Boot Certification Verify".
Now the problem is
first I tried to put the device into download mode (in order to go for TeenyBin or KDZ method)by forced power off and pressing vol up+vol down and inserting the usb but it is not working and same errors comes. No Download Mode working :crying::crying:
2ndly I tried to hard reset by pressing vol down key and power button .Reset but then rebooted into recovery Mode.
As another option I tried to adb sideload a zip ROM but it said "protocol error". Same is the case for adb push command.
Now I am stuck with secure boot error without Download Mode but I have acces to recovery mode. What should I do now????
Please completely read the problem :crying::crying::crying:

Can't get into Download mode

Edit: I somehow could reach to fastboot mode and flashed laf.img to recover download mode but I get a boot certification verify error. I can access the phone and recovery but cant access download mode.
I decided to upgrade to MM from LP using kdz method. However I could not boot into download mode with any method. The phones just reboots normally. I tried hard button(volume up and connecting to pc), I tried adb reboot bootloader, I tried to reboot to bootloader from twrp and none of them worked. In every method I used the phone just reboots normally.
I have root + twrp with stock 5.0 rom. Any help appreciated, thanks!
