LG G3 D855 "Secure Boot error" - G3 Q&A, Help & Troubleshooting

I know this has happend to other people, but nothing worked for me. Maybe some of you guys had same problem.
I can't go into "Download mode"
My PC doesn't recognize device
But I can go into recovery. I have flashed latest recovery. Tried flashing latest LOS (it flashes without any errors) but still when restarting I'm getting "Secure Booting Error" and after screen goes black red and blue led starts to flash

If you have flashed twrp, does it work to reboot to download mode from it?

Could not do normal boot error

Hi,
I was trying to get CWM recovery onto my phone but I believe something went wrong. Whenever my phone turns on, it goes straight into download mode with the message in red saying "could not do normal boot" with the ODIN mode and such listed underneath it. What do you recommend I do next to resolve this issue?
Flash to stock and start again. You're al good... :thumbup:
Thank you, that resolved my boot error issue. I tried flashing recovery-clockwork-touch-6.0.1.0-i9300.tar with ODIN, but whenever I try to reboot into recovery, it loads a message saying "rebooting into recovery" then my screen goes black. I have to reset the phone after that to get it to reboot. Any suggestions?
Wait... Edit... Why are you using a i9300 file... Isnt the att gs3 i747? Easiest way to install recovery if you can boot to homescreen - download goo manager from play store and hit menu and install recovery.
That would explain a lot... When I'm in Goo, I only have the options to install OpenRecoveryScript and reboot recovery. I installed the script then tried to reboot recovery but have the same issue with the blank screen.
Neverymind, it loaded up perfectly. Thank you for all your help!

[Q] Stuck in infinite recovery loop

I screwed up.
I wanted to install a new custom mod after purchasing a new SM-P605. I rooted my device, and searched for a while on how to install a custom recovery (TWRP). I downloaded ODIN and flashed it a couple of times but it didn't work, I kept getting a "recovery is not seandroid enforcing" and the screen freezes.
Then I tried Rashr's flash tool to install TWRP for me, and afterwards selected "boot into recovery".
Now i'm stuck in the same screen, but whenever I tried to restart, i get back to it, and can't get back in the system.
What can I do?
I'm unfortunately stuck in a very similar situation.
I was updating the firmware on my tablet to 4.4.2 downloaded off Sammy mobile, uploading using Odin. I've done this dozens of times since my S2 which was 12 handsets and 6 Android tablets ago. This time, about a third of the way through the process hung for a few minutes then the device restarted without warning and now its stuck in a loop where it starts normally

Then says
RECOVERY BOOTING...
RECOVERY IS NOT SEANDROID ENFORCING
Set Warranty Bit : recovery.
Then this

and stays on that screen for short periods before rebooting and starting the above again.
Thanks in advance for any tips or help you guys can provide!

Thanks, but it turns out the solution to my problem was simple. I took it to the place I got it from and the guy just pressed power, vol and menu button long enough until it rebooted. I'm quite a noob it seems.
I'm not sure if it will help you Nationalmaverick, because my problem was slightly different.

[Q] 'Secure boot Error!' at boot, download mode and factory reset don't work

Hello,
Here is what led to my issue:
I rooted my phone using this method: http://forum.xda-developers.com/showthread.php?p=38886073#post38886073
Downloaded clockwork rom manager.
Here comes the thing I don't remember. At least i know that the last thing i did was to click on 'backup current rom'
After this the phone reset itself and this message came up:
Secure booting error!
Cause: boot certification verify
Then i tried to reset using the power button, which led me to the 'battery full' screen - afterwards i was able to reboot. As stupid as I am I just tried the same thing again. And ever since i am stuck at the 'Secure booting error!' screen.
I am unable to enter download mode. I get to the 'Hard factory reset' screen, but if i accept doing so, it says 'Secure booting error!' again.
I also remember clicking on 'restart into recovery mode' at some point, but this is not the last thing i did.
I am really desperate. Please, help me!
Well i had the same issue today... It happened after i did two changes. One of them was to to try to relock from freegee and flash twrp again from freegee. In my case i was able to go in download mode and flash original kk rom with lg flash tool.
Unfortunatly, trying to boot in downloadmode, i still get the same error :/

How are you trying to boot into download mode? And what factory reset screen? It seems as though you did not unlock the bootloader using freegee, if you make any changes and relock the boot loader you will get that error. But it seems that it has not been unlocked. If you hold power and volume up what happens? Same thing when power and volume down, one of them is recovery (possibly factory reset you are seeing) and the other is download mode. I don't remember right now but you should read the whole softbrick thread and see if you are missing something. You may need to use LGPNST to go back to stock, you can also use that program to flash a new recovery so read carefully and follow all steps.
When this happened to me I was able to flash an unlocked bootloader and it allowed me to use my phone again as it was before doing something stupid (for me it was an attempt to re lock the bootloader).
well, i managed to get into download mode. Obviously i used the wrong method to get into download mode...
I used this method and everything worked fine, so far. : http://forum.xda-developers.com/showthread.php?t=2249500
My phone doesn't boot now. Fast Boot doesnt work aswell.
All that happens is a white battery showing on the screen and when i try to fastboot all that happens is that the LED is blinking or glowing red after some while.

What do you mean when you try to fastboot? Fastboot is basically the bootloader and allows you to select recovery or download mode. What you should have done after following that thread is go to recovery and wipe everything and flash a new ROM.
If you are saying that the bootloader is not coming up and allowing you into recovery then I believe something was missed.
After trying out some varioants of this it worked: http://forum.xda-developers.com/showthread.php?p=40274560&highlight=red+led#post40274560
I wiped the phone, but since I had to leave over the weekend i just turned it off and went away.
Now that I am back, nothing works now :/ The Phone doesnt react to anything, not even donwload-mode.
Is the battery too low maybe? It's on the wall now for a few hours, but it still doesn't react. It's not warm either.
edit:
when i charge the phone, i will get a 'watchdog bark' after some time allowing me to get into recovery. accesing downloadmode from there doesn't do anything. strangely, the recovery isnt trwp although it should be because teenybin comes with it. it's 'bbs.gaodi.net' which doesn't have a sideload feature. what do i do now?
edit2:
after 10000 tries i got into download mode. i don't want to **** up now so i won't do anything until i know exactly what to do.
any advice?
edit3:
got it working by flashing another teenybin which included trwp - then i installed miui via sideload. i don't have signal though, but i will open another thread for this since this is another issue.

GT-I9190 stuck on TWRP Slash Screen and Unable to re-install

Hello guys,
Thank you for reading, any help is appreciated.
My device was running the latest release of CM13 (cm-13.0-20160418-SNAPSHOT-ZNH0EAO2NK-serrano3gxx) and TWRP v3.0.2-1
So yesterday afternoon my phone randomly shutdown and I was unable to get it turned back on until this morning.
However though when i did manage to get it powered on after hours of failed tries it was stuck on the Samsung boot screen.
I've since tried to access the TWRP Recovery (Pwr + Vol Up + Home) but it sticks on the TWRP slash screen and then attempts to reboot normally (which as i said stick on the Samsung boot screen).
I also tried re-installing TWRP via Odin and it appears to be installing properly and successfully but when i attempt to access TWRP it again sticks on the splash screen,
I've also tried installing CWM Record via odin and that also appears to be installing properly and successfully but when I attempt to access the recovery I am yet again greeted with the TWRP Slash Screen which has lead me to believe something is going wrong.
Any ideas or suggestions as to what may be going on here ?
Thanks in advance, any help is appreciated.
Hey again guys,
I have tried installing stock rom via Odin, It says Pass but nothing at all seems to be changing.
I'm beginning to think Odin may really not be working at all or something is wrong with the phone
Update: I tried flashing TWRP recovery via Heimdall and it appears to have completed successfully saying "RECOVERY upload successful" but when i reboot immediately after into Recovery mode it still sticks at the TWRP 3.0.0-0 Splash Screen then attempts to reboot normally which as mentioned earlier also sticks on samsung slash screen

"Boot certification verify" after device test

Greetings,
I am running Zoe Rom 6.0, I had problems with proximity sensor, the screen wouldnt light up after receiving calls, so I got into hidden menu and ran mt device test, after that phone turned its screen off and blue and red dot started to blink, I thought that is a device test procedure, but actually its just stuck like that.
I can enter TWRP recovery and download mode, but I am at work right now. I wiped clean several times and restored from backup but "Boot certification verify" error on every boot still persists..
I even flashed 7.1 ROM from SD card from TWRP and same outcome.
Why doesnt the error go away after clean flash? or clean restore?
Is there a way to fix this?
thanks for help in advance.
