Secure boot problem, but CAN boot in the OS. I just cant access recovery

I cant boot in to OS nougat 7 lineage os 14.1 without a problem , but cant access recovery and because of that cant have root access. There is no recovery installed. It says something about secure boot authentication when I try to get in recovery. Fastboot is available and when I connect it to LG support tool, it shows that it is d802 model and asks me if i want to upgrade to lollipop. The thing is that I am on nougat 7.1 and when normally connected to this software, it doesn't show phone model, but in fastboot it shows. Does this mean that I can let it upgrade the OS even if I am on lineage os and have installed hybrid bootstack?
Because people tend to say something that's not relevant, I will repeat: If I'm on nougat 7.1 OS, and have hybrid bootstacks installed (whatever that means), can I "upgrade" (in this case downgrade from nougat) the OS to lollipop even if I have custom os at the moment, using LG Support Tool? Considering that the phone is not recognized by LG support tool when booted, but when in fastboot it shows in LG support tool which phone model it is. It looks to me like I could let the LG tool to do it's job. Maybe it installs it's own bootstack, recovery, rom ...etc and whatever was previously there, it just gets erased. Am i right about this ?

Hi #Fear,
I'm not sure but iykeDROIDâ„¢ stated:
ROM Firmware Required: Must be on Nougat[SKU: XT1762]
Perhaps you've to use RR ROM - Resurrection Remix 5.8.5-20180122 by iykeDROID for Moto e4 Mediatek "Woods"
Do not forget to install no-verity-opt-encrypt zip file after flashing.
Hi, just to update you guys, i am now running on Resurrection Remix N v5.8.5.
For future XT1760 variant users.
This guide works to install TWRP. *don't forget to thank OP.
However, if you encounter "unable to mount /data", you will need to change the tick 'data' and select "file system" 'ext2' then back to 'ext4', I was on a first recovery that doesn't allow me to do so, so I flashed another recovery which it was able to.
Once that is done you will be able to flash the 'no-verity-opt-encrypt zip file' without any error, but if you still encounter the 'unable to mount /data', then maybe you will need to try another recovery.
Then I flash the custom rom with gapps and it booted b-e-a-utifully.
On another matter, if you encounter bootloop on the moto logo, and you are unable to enter recovery/fastboot/adb command, this is for you.
Google for SP flash tool. Make sure you have all the drivers installed. Get the stock Moto e4 file.
*WARNING* THIS WILL CLEAN YOUR PHONE OF ALL DATA
You can restore your device to stock using the program. There is multiple guides on youtube and a simple search can lead you to the said files.
