Secure boot error(not bricked) - G3 Q&A, Help & Troubleshooting

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.

The error means you didn't patch the recovery.img with loki_tool before you flashed it. Read the manual installation procedure found in the CWM recovery thread in the Original Development section.

Yes, I know but I'm not the only one who has this problem.
The question is : How can I fixe it without re-flashing the hold stock rom (1,2Gb) with PC and lost root ?
If you can get it to boot into the system, then you should be able to fix the problem by following the manual installation instructions using loki_tool. You can find those instructions on the CWM thread.

can go to recovery instead gives 760 fastboot mode started

Try to flash other twrp img through flashify app or autorec for LP....
Or use adb......
Sent from my LG-D855 using XDA Free mobile app
Also make sure your SD card isn't formatted.. That worked for me but not sure if our issues were exactly the same

Can't access my G3 (D855), it only boots into cyanogenmod recovery!

First of all, I had a LG G3 (D855) with cyanogenmod 13 on it.
Since my twrp didn't work and i had a pretty old cm13 version on my G3, I wanted to flash twrp again and I used the AutoRec apk from this post (http://forum.xda-developers.com/lg-g3/general/root-twrp-marshmallow-d855-30b-t3286268), because I couldn't flash anything in my old twrp.
After flashing the new twrp, my G3 could only boot into the twrp recovery, so I searched for a solution and fount this post: http://forum.xda-developers.com/lg-g3/development/fix-stuck-custom-recovery-trying-ota-t2907508
I did everything like the guy said in the post and it didn't work, so I used the last command in his post. After trying to boot into sytem it didn't work, but this time I got into the "cyanogenmod recovery" in which im stuck now.
So the first thing I did in cm recovery was looking for the possibility to flash an image, which just isn't there. So I tried flashing the newest cm13 nightly through the "Apply update" option in the cm recovery, which didn't work because I needed Baseband version 21C.
After that I obviously tried to flash Baseband 21C, which again didn't work, because the footer is wrong.
So I surfed through the internet, when I had to notice, that ADB (and fastboot) doesn't work in cyanogenmod.
Now I'm stuck here with this ****ty cyanogenmod recovery, where I can do nothing.
I hope that anyone of you can help me with this problem
Can't you go back to stock with a KDZ flash? Just boot into download mode.
A similar thing happened to me, but it was a TWRP boot loop. I tried the LGUP flash of a .kdz file, but that failed, so then I tried an earlier version of Android using LG Flash Tool 2014 and it was fine after that. Then I just updated to latest stock Android and rooted with Kingroot. Can you at least boot into download mode? (power off while not connected to PC, then press vol up I think at the same time as plug in USB cable).

Can´t install TWRP / Lineage on Lg G Pad 8.3 V500

So a couple of months ago, I installed the official, yet korean, firmware (Android Version 5.0.2) on my Lg G Pad V500.
Now I wan´t to install Lineage OS but I always fail to install TWRP.
I followed this guide and also tried the guide from lienage os. I flashed the proper TWRP version with the official TWRP App and the app claimed that it was successfully.
Here comes the problem:
I can´t boot into recovery mode.
I tried it with adb "adb reboot recovery" but ended up by the LG Logo and a message in the upper left corner telling:
secure booting error! cause: boot certification verify

I also tried the key combination while booting (POWER + volUP + volDOWN) but that didn´t work either.
Here are some Specs:
Android version: 5.0.2
Kernel version: 3.4.0
Build Number: LRX22G
Software version: V50030a
Which TWRP Version did you use? I have a v500 too and was running fine with twrp 3.2.2.0. I yesterday updated to twrp 3.2.3.0 and get the same error while trying to boot into twrp. I guess 3.2.3.0 is the problem.
I'm also getting that since latest updates... Spent 3 hours trying to boot into recovery only managed it once and clearing cache didn't fix it. Haven't been able to get in again...
Tried with TWRP 3.2.2-0

I tried version 3.2.2-0 but go the same message when trying to reset.
Which rooting method did you use? I bought mine v500 used and twrp was already installed, so I hadn't to deal with rooting and all that stuff. I recently read a lot about and think I will have to try different method to get twrp running again. But if you have hints for me, I would be thankfull.
I vaguely remember that you had to use 4.4 kitkat base for root & TWRP, not 5.x. Don't know if this still apply.
