Hello!
I'm quite new to the android rooting scene, so I encountered this problem on my LG G Pad 8.3 (v500)
I had installed Lineage OS with android 7 (can't remember exact version) and tried to root the device
I tried flashing SuperSU.zip with TWRP, but it failed, and now, when I boot, it shows me this:
--------------------------------
Secure booting Error!
Cause : boot certification verify
--------------------------------

I tried getting into download mode, recovery mode, adb, flashing stock rom, but none worked. They all lead to the same error. Best result I could get was with download mode: the lg logo for a few secs, and then a black screen
Is there anything I can do to unbrick my device?
we are two with the same problem

You must go with your Tablet into the download mode and make a restore with the LG Mobile Tool on your Windows PC ,
You have a guide in a post by the section android development !

So I was trying to install TWRP on my freshly rooted V500 5.0 korean kdz, followed the steps exactly and I tried to reboot to recovery and got the
Secure booting Error!
Cause: boot certification verify
Reading through a few other threads, I tried going into download mode and upgrade recovery through the LG mobile support tool, but that says no items to upgrade. Now, my tablet will not boot up past the error screen and I'm having no luck finding any way to get it booting. Any ideas? Thank you in advance for any help!!
EDIT: KDZ back to 10a
Same here!

First find out which variant your mobile is.than download the exact variant's .kdz file. than flash it with LG UP and select refurbished mode. you can put it in download mode than connect it to PC if its not connecting normally. Hopefully it will boot up to life. let us know what happens
Hello,
I have a lg g pad 8.3. Today I've tried to do the downgrade Lollipop -> Kitkat, but something wrong and I have the boot logo restart. But I've put my G PAD in download mode and now I'm trying to install various version of stock version through LG Flash Tool. But on my Windows 10, I receive the error "LGUserCSTool LG Mobile has stopped working........", while on my Windows XP pc, the .kdz of the version 30a.kdz stop the installation at the 95% and the LGMobile Support Tool tell me to retry the installation, while with the version 10b.kdz, finish at the 45%.
What I have to do now?
I see only DOWNLOAD MODE on my tablet, If I shutdown the tablet, reappears the Download Mode, no LG Logo.
Sorry for my bad english.
I followed this guide but used the 10b.kdz instead of 30a

I noted that using 3GQCT worked fine (but required a hard reset)
CDMA caused "LGUserCSTool LG Mobile has stopped working"
