Hello everyone,
It's the second time I have a problem with my LG Spirit but now I seem unable to do anything
About month ago my LG was getting stuck on LG loading animation but then I managed to flash it via Download Mode and LG Flash Tool. Everything went fine and the phone was operational till today.
After battery had gone flat I plugged it to recharge but "Security Error" occured.
While plugged in it constantly shows the error message and reboots again and again.
Of course, I tried flashing via Download Mode but in vain. Although Download Mode shows up, a message "Secure booting error. Cause: Boot certification verify." appears, the screen blinks in blue colour and turns off.
Any PC with any USB wire recognizes the LG. Debugging mode is switched on, but no modifications such as TWRP, etc. were ever made.
I also managed to restore default settings, but with no results.
Any ideas what to do?
Thanks in advance
I saw this thread earlier, maybe it can help you?

Hello everybody,
I'm having a problem : after failing to flash a rom with cmw on my F320S, i got stuck in bootloop : when i turn it on, i only have the LG logo with LED on. I can go to download mode, but then the phone isn't recognized anymore by my pc.
So i tried everything i could from this forum :
- with LG mobile support tool (from http://forum.xda-developers.com/showthread.php?t=2432476) : it says "upgrade is stopped because of an error". The phone is plugged with LG logo on, and as i said before if i go to download mode it keeps telling me to plug the phone.
- with flashtool v1.5 (http://forum.xda-developers.com/showthread.php?t=2475045) : if i plug the phone and turn it on, it asks me to go to download mode. But then the phone isn't recognized, and it says "download failed".
- with lg mobile support tool (the official one), it says my phone is up to date, and if i try the recovery after error option, the download never starts (i left it all night long).
I also tried to reinstall the drivers, with no effect.
As i said i'm on F320S, so all i have for startup is normal boot (stuck on LG logo), download mode (not recognized by computer), and if i push all 3 buttons a strange korean menu (google translation says it's "external structural mode" or something like that).
So if anyone had an idea, a solution, well anything that could help, i would be very grateful.
Thanks you all!

If anyone could even give me an idea, a hint, something? Did i miss something? Or is it bricked forever? Thanks!
can you boot into recovery?
If you can. either do adb sideload or flash a custom rom
Nope can't load into recovery... And in download mode phone isn't recognized, that's the main problem i guess, otherwise i would flash back to stock
Hey i finally maanged to get into recovery. But factory reset doesn't seem to work (unknown volume "/sdcard/ .andoid_secure). Wipe data didn't fix bootloop. Adb says no device. So what can i do?
Well after a whole day trying to get adb to work, i finally ended connecting to my G2. I followed all the steps to install twrp from here http://forum.xda-developers.com/showthread.php?t=2449670 . But now when i boot i don't have twrp, and if i push vol+ and power i don't have cwm either (says recovery mode, loading, and never loads)...
I guess i'm in trouble, could anyone help?
hello anyone?
So, here's the backstory: I rooted my phone on Kit Kat. I used ioroot 25, and it was easy enough. However, I tried and tried for hours upon end to download a custom recovery. All I managed to do was lose stock recovery/ every time I tried to go to recovery, I would get a Boot Certification Error. I wasn't too mad, just disappointed. I don't really remember what I did beforehand, but I turned off my device. When I tried to turn it on, it gets stuck in a bootloop. When I turn it off, it stays off for about 3 seconds then turns itself on again, still with the Error screen. That shortly disappears, and then it stays on with a blank screen. I can get to the factory reset page, but not the download mode. So when I tried to do this: http://forum.xda-developers.com/showthread.php?t=2663369, I was stuck at the download mode part. I don't have a way to enable USB debugging and my phone has no recovery. What do I do?!
Update/Fix:
Got it to work again! I let the battery drain to 0% so I can boot it into download mode where I used the LG FlashTool to install ZVC. It's completely working now. I learned from my mistake.

How it occurred:
I was trying to flash a ROM today with TWRP but I accidentally deleted/formatted my G2. (I haven't flashed anything in a while so I forgot that would delete the .zips) TWRP was unable to mount the USB so I restarted my phone and now I'm stuck at the LG logo.
What happens:
When I hold down the power button the screen goes black and the logo pops up again with the green and blue LED, so I can't turn off my phone completely. I tried going into download mode and recovery mode but it just shows the LG logo and nothing else.
If anyone knows how I can fix this, that would be great. :good:
Also, I have LG FlashTool. If I can get into download mode I think I'll be able to fix it.
Mod Edit:
Fixed and Thread closed at OPs request
I can't boot my LG G2 since I attempted to install Cyanogenmod 13 to it. It is not a "Security Error" that I can fix by flashing to stock rom. When I press and hold the power button it usually shows nothing, but sometimes it shows the logo for half of a second and goes black. I can't acces download mode or recovery, and when I tried to connect it to my pc, it opened dozens of driver(like C:\, D:\) errors, so I plugged it out and all of them gave error by saying can't open, parameter error, format the disk etc. I really need urgent help!
By the way I had downloaded opengapps and cyanogen mod 13 when I was able to access twrp.
I should add this: it continues working there is a shining black screen all the time. If I try booting it when it is out of charge, would it work?
P.S: When I connect it to a PC this shining black screen is winking.
Hiya I managed to brick my d802 after wipng from twrp I believe.
It seems hard bricked and nothing is working, all the happens when I boot is that i gets stuck in the LG logo. If I try download mode its not working, and impossible to boot into recovery mode, when I hit the power button all it shows is "charging! ??/100" in a yellow font in download mode
Its not showing up in windows device manager as anything but "charging" also tried the guide on short circuiting the connections on the processor and its not responding to that also.
Ive attracted a link to a screenshot of the charging error. any advice is appreciated.

If it's stuck in LG logo, it's possible to turn it off completely, put it in download mode with a computer and flash a stock kdz. No need to fry the transistors.
