Secure boot error(not bricked)

Hi,
Phone Model: D855
Software Version: Lollipop
TWRP Version: 2.8.7.0
I was looking for a solution and all I found are solutions for bricked phones which is not my case.
I tried flashing via Flashify the "TWRP" recovery.
When i rebooted into recovery from Flashify or Quickboot it says "secure booting error" or what ever and gets into a bootloop - which ends when i just take the battery out.
What should I do to use the recovery?
Thank you!

Downgrade to KitKat and then install TWRP

Use autorec for d855 /available in playstore/. Should work fine on LP. After flashing successfully update to 2.8.7.0 via recovery.

Need urgent help for 3 big problem on my lg g3

I had some issue with twrp and it got stuck on The teamwin screen. So I restore lg os using the lg flash tool. After I update it to lollipo and install autorec d852 lollipop so I can install twrp. It install succesfully. I went on twrp and the problem started. It was stuck on it. I decided to get into fastboot mode by removing download mode ( I have a back up of it) and I did these following commends
Fastboot erase recovery
Fastboot flash recovery cyanogenmod 12.1 recovery for d852..
I flash the cyanogenmod recovery so I could install a aosp. I install cm13 and it damage my micro SD card. I finally fix it . After I flash blisspop because it was limited the customization of cm13 compare to other aosp roms. Once finish setting up everything on my internal storage, I tried flashing again twrp by auto rec ... It didn't work , so I tried flashify but it also got stuck on teamwin screen and I could access anything option. I started looking online if someone had experience something similar but no one had this type of problem that after doing a full reset and reinstalling it, it wouldn't work. So I went on fastboot mdoe ( I don't know how to get download mode back so I stuck in fastboot mode instead of download mode ) and did the previous comments that I did to flash cyanogenmod and I flash the cyanogenmod recovery because I need a working recovery. Since then I have been trying to fix the teamwin screen problem.
I NEED HELP WITH MY 2 PROBLEMS.
-I can't find a way to enter download mode again
- Can't get twrp to work
Someone help me please

I have the same problem too on my D855 also with KitKat. I also want to install custom ROM but can't due to this problem.

No Recovery and Download Mode

Hi all,
I bought a used LG G3. It's running on KitKat and software version is D85510i. It had stock recovery installed but download mode was missing. Whenever I entered the download mode, it said "fastboot mode started". I can't find the laf.img for D85510i and the ones for 30B/20E/etc don't work (I tried flashing them with fastboot). So I thought of installing custom recovery. I came to know about bump! TWRP. This phone was already rooted with latest su binary installed. I downloaded flashify and flashed bumped twrp after taking backup of stock recovery. But when I rebooted into recovery, it said "fastboot mode started" and somehow, stock recovery.img got deleted. Now my phone just boots into system and recovery/download mode don't work. I even tried flashing bumped twrp with fastboot and adb as well.
1. Can someone explain why twrp isn't booting and help me flash it?
2. Can someone provide me the laf.img for D85510i? I don't wanna download the whole firmware to install just a small laf.img. if someone has the stock D85510i.kdz, can you please extract laf.img from it?
3. Moreover, the housing says D851, while sticker under the battery and in setting, says it's D855. The IMEI on the sticker under battery and the IMEI of the phone also match. So is it possible that the housing is just changed or is there any chance that someone successfully flashed a D855 firmware on D851 and now I'm having issues with recovery and download mode because of that?
