secure booting error - G2 Q&A, Help & Troubleshooting

I have vs980 with euphoria 1.1 ROM. After I flashed ROM everything worked fine. When I went to install a new ROM with twrp, I rebooted into recovery. But it won't go. I have the lg sign and an error comes up, Boot Certification verify - Secure booting error.
I have tried searching for an answer, but all the posts are for the same error but with stock ROMs.
How do I get into recovery? It says its installed, but won't boot into recovery.
What do I need to do??? Please help!

[Q] Stuck in TWRP

Good day
After using different methods to try and install a variety of ROMS inclduing CM11, MUIU, FirefoxOs and KitKat 4.4.4.2 Brannded, I'm stuck in the TWRP 2.6.3.2 gui after using flashify and not making a backup. When I sideload and install miui_g2_ws008_4.5.19_5b586f93ad_4.2 it installs sucessfully according to the log, but I get stuck in boot loop after gapps has been loaded in 1st boot. With cm-11-20140522-NIGHTLY-d802, openrecovery-twrp-2.7.0.0-d2vzw, philz_touch_5.15.0-d2vzw, TWRP_v2.3.3.0_P350 I get the Error Executing Binary Zip. When I sideload openrecovery-twrp-2.7.0.2-t03g it installs successfully, I select reboot, it ask me to install SuperSU I say yes and then get stuck in LG boot loop. LG flash tools get stuck at "waiting for connection" when I try to flash it with LGD800AT-01-V10d-310-410-AUG-14-2013 and LGD800_20130904_LGFLASHv160.

D800 no recovery, boot certification verify

So I tried flashing CM13 via TWRP and I did, but whenever I try to access the recovery it just shows the LG logo and the boot certification error. When I try to install a recovery via Autorec it shows an error when installing the loki tool, so I don't know what to do. Any help? CM13 works fine and I can boot to it, but I'm wondering how I can access my recovery again. Thanks

Little help stucked on OP logo at boot

Hello,
First to get this out of the way i have searched the topic and there were several "solutions" none worked for me.
How it started, I downloaded the latest LieneageOS update as always, set the phone to do it's thing, came back and the phone was stucked on OP log, tried a little reboot, nothing.
No access to recovery or fastboot.
computer wouldn't recognize device even after installing drivers, this guide helped me a little https://forums.oneplus.com/threads/...ck-guide-for-a-hard-bricked-oneplus-2.347607/
found tools got fastboot back and original recovery.
via fastboot attempted to installed TWRP
fastboot flash recovery twrp****.img
and then tried to boot into recovery
fastboot boot twrp****.img
Not able to boot into twrp
after all that my phone still stucked on the boot OP logo
any help would be greatly appreciated.
Anyone has any idea, sorry I have been scouring and reading everywhere, but I can't find a solution.
Thank you
So i have been trying many things and finally getting somewhere. I apologize for the long post, but i have been trying so many things to get this device back to speed.
So flashing TWRP newer version for some reason is not letting me boot into recovery.
I have flashed twrp-2.8.7.0 and i am able to boot into recovery, however when trying to install the ROM (LineageOS 16) i get error E3004.
Searching the web i find that the correction is to that error is to update TWRP, thus i have tried flashing
twrp-3.2.1-0 and twrp-3.1.1-0 and once installed i am not able to boot into recovery again.
I flashed 2.8.7.0 and i was able to get in, thus from inside TWRP i did an image install of twrp-3.1.1-0 and rebooted, recovery won't load. I proceeded to repeat this until i get a result.
I flashed twrp-3.0.2-0 and be able to boot. However still not able to install LOS.
Once i tried flashing twrp-3.0.2-1, recovery won't load.
For sake of argument i flashed twrp-3.0.2-0 and attempted a image install for twrp-3.0.2-1, but the system still won't boot to recovery.
I have completely formatted the phone.
I hope someone could give me a little advice . Thank you.

-PLEASE HELP- UNABLE TO FLASH TWRP OR ROOT

Hello
Sorry for my bad english
a few months ago, i decided to flash my first custom rom (One UI rom) and it worked fine
then i was testing a lot of other roms too until i tried lineage os 20
when i flashed lineage os 20, i decided to try another rom but i was stuck on the twrp logo screen. i tried methods of fixing it but none of them worked.
after trying a method of flashing twrp once again, it failed and i got stuck in a reboot loop and could only boot into download mode. so i booted into download mode and flashed a stock rom.
everything was working fine again until i wanted to try another custom rom. At first whenever i would flash twrp, they would always fail. but later i found the cause of that and fixed it. then, flashing twrp would always pass but my device would get stuck on a reboot loop once again and i had to flash stock rom again.
i tried rooting using auto root but it would show me a verification failed error and i had to reset my device. so now im stuck on a device which cannot flash twrp, nor can it be rooted. its been 1 month and i could not find a viable solution so any help would be extremely appreciated.
You have to just reflash your fastboot rom with fastboot mode unzip it and double click on flash_all.bat file or something like that
it is a samsung, there is no fastboot mode
