Root LG Security Error?

OK, so I want to try my hand at building a ROM. I found a guide to create a ROM from a backup, so I made a backup of my system, converted some apps that I wanted in the ROM to system apps. Then I booted into recovery, did a factory reset and wiped internal storage and cache. When I rebooted to set things up for the ROM, I encountered the LG Security Error screen. I was able to restore my backup and the phone is fine, but what the hell happened?!
 
Got a link to the guide? My best guess without knowing more was that one or more of those converted apps caused the error.
 
I want to make a custom rom from my system but im afraid this will happen and idk if i would be able to put the data from "theming" apps into the rom

My plan was to go in and set up the theme stuff, then make the backup. I think I know where it went wrong though... My build.prop was modified by another mod... Entirely possible that this caused the security error. Only thing that really makes sense. Going to push in a stock build.prop and see what happens.

Running anything with a custom kernel requires either the boot image to be signed or the bootloader to be unlocked. Since we don't have easy fastboot access we are signing using Bump. The build scripts aren't set up to do operations in the correct order so the image is bumped after it gets put in the zip. Replace the boot image in the zip with the one that's in the out directory.

My brief saga with this is documented in the dirty unicorns thread.

Good info, but I'm not sure what the relevance is? I got the security error after doing a factory reset and cache wipe on my phone. Nothing had been flashed, or was being flashed. If I'm missing your point, can you please clarify?

On that note however, at the time of the reset, I had a modified build.prop and custom kernel installed. Could either of those factors caused the error?
 
Sorry, when you said you were building a ROM I thought from source. But yes, the custom kernel is the likely issue. That would be a modified boot image, and goes back to my explanation. Which kernel did you try?

The only one we have... Uno. It was installed before the wipe, and I've factory reset with it installed before. Why would it be an issue now?

The other thing I was thinking was that some of the apps were installed from the play store and wouldn't normally be a system app. child that have been the issue?

So far as I know the bootloader should only care about the boot image. You might have a corrupted download.

You still seem to think I'm trying to install something. This happened when I did a factory reset. I didn't install anything, I'm using the kernel right now. There's no download to be corrupted.
