Security error after recovery update

I have a d802 . I had cloudy1.3 and twrp 2.7 installed with autorec. I tried to update it using
dd if=/sdcard/recoveryfilename.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
(from twrp page, with the latest img file).
But I coudn't access recovery, some error about security. Then I shutdown my phone and then it booted fine into system. I retried to access recovery but nothing.
So I decided to return to autorec, I installed it, I clicked "Flash Recovery" and now my phone doesn't boot in any way.
It show "lg security error" and then shutdown.
I can access download mode. Is there a way to fix my phone without deleting everything?
I'm sure the problem is the recovery, I was messing with it, can I bring my phone back and don't delete my configuration, photos, apps?
Thanks

I'm so happy!
I did it!!!
I managed to boot into recovery with the usual combination of keys (with the method that ask you if you want to format, but then you press power and it boot into recovery).
From there I saved everything using adb pull (Just in case). Then I dirty flashed Cloudy 1.3 and my phone is back !
I hope my experience can help someone

[help] Can't install twrp

hii guys i can't install twrp on my play.....whenever i enter the command i get the error
"error: cannot load twrp-lux-2.8.7.0"
also the windroid tool says twrp flashed successfully but when i reboot into recovery it boots into stock recovery with "no command" on display
any help appreciated

What are you typing when trying to flash?
fastboot flash recovery nameoffile.img

Not sure if you are having the same issue I did.
Are you flashing TWRP then using the reboot command to restart your phone immediately?
If so, try flashing TWRP again. Instead of rebooting, try to access the recovery menu right after flashing. This worked for me. The post I saw related to this mentioned the Moto was overwriting something when rebooting. I haven't had any issues since.

Flashed TWRP, phone no longer booting

I've been following the steps to install a custom recovery and ultimately root, but I'm now stuck unable to boot my phone.
I started on Android 7.1.1 and this is what I've done:
Installed Version UnlockTool_2017_0803(android M)
Unlocked the boot loader using the app
Restarted and entered fastboot
Ran "flash recovery twrp-3.1.0-0-Z01H-20170408.img" (downloaded from https://mega.nz/#F!p90wgAaY!l1JbJilmAUEKTKWu43pT9w)
Checked that TWRP was successfully installed (it was)
Rebooted but I'm stuck on the "Powered by Android" screen
I can see the following information:
Code:
FASTBOOT MODE
Image version - WW_user_20.31.49.2_20170620
DEVICE STATE- unlocked
Any advice on what I can do to boot successfully? I was planning on following the steps in the no os, no recovery.img (https://forum.xda-developers.com/zenfone-3-zoom/help/os-recovery-img-t3628944) thread, but it doesn't seem to be the same problem that I'm having.
Anyone have any tips or suggestions?

Let me answer my own question. I found that I needed to install SuperSU for the phone to boot correctly. I had assumed that I could do SuperSU or Magisk after having checked that I could boot first ... my mistake. Hope this helps someone else.

HELP! Phone won't boot from twrp!

I've unlocked the bootloader, flashed twrp from pc and I was going to flash the supersu zip. Unfortunately, when I went in recovery (twrp) and flashed the supersu zip(installation process didn't show any problem) I clicked reboot and the phone didn't boot! It just turns off(no led or similar). I have fastboot and twrp access, I tried flashing omnirom using the adb sideload command, everything went fine but still when pressing reboot nothing happens! I even tried to boot manually (after flashing the ROM) with the physical button but still nothing(this time the led blinked twice).
I used the latest version of twrp for Athene, version 2.82 of supersu if this could help.
Edit: was it necessary to flash a different kernel, as it was a nougat rom? The rooting guide I followed didn't mention that.
Edit: Everything worked fine before Supersu, the problem must be related to Supersu but how can I solve?

Unlocked bootloader and installed twrp but magisk won't install

Alright so, I've managed to uppercut down to 13a from 1ca, unlock the bootloader, install twrp. Never installed supersu, but when the phone booted to twrp I installed the magisk zip with no errors. After booting the magisk manager never showed up as installed. Installed it manually, ran it, said magisk was not installed and device fails safetynet and pts. Downloaded the latest stable magisk, booted into twrp and tried flashing it AGAIN. This time I get an error that it can't flash it. I'm totally lost here. This is all I lack to have systemless root here. Also I can't seem to boot into recovery via button presses. I keep getting the pink triangle and despite holding vol+ and power, the device just boots normally. I have to force recovery via adb on pc.
Any ideas?

Bueller?

I kinda ran into a issue with magisk not installing properly and how I got around it was to get your roms boot image file and make a zip of it. Then, go to twrp and flash the boot image, then flash magisk.

You installed the magisk zip and the magisk manager apk? Did you try flashing the rom and installing masik and the apk again?
For some reason on the lg phones it won't boot directly to twrp. when you boot to recovery and it ask if you want to reset, select yes. If you have twrp installed, it will then boot into recovery.

I have not since my bootloader is unlocked I heard u can't go back to stock on the vs995

Nothing i suggested requires stock.
With the phone off
press and hold volume down
press the power button and hold until you see the lg logo
while holding the volume down, release only the power button and press it again and hold
if you did it correctly, you should be in recovery
it will ask if you are sure if you want to reset your phone a few times
select yes, and yes
If you have twrp installed it should boot up in twrp
Or
If you already have the bootloader unlocked, make sure that developer options are enabled
go and enable adb debugging
connect usb cable
use adb to boot into fastboot
use fastboot to boot into twrp
From twrp you can flash the rom zip, magisk zip, and then install the apk after the phone rom boots up
which rom are you using? which magisk zip? which magiskmanager.apk?
