Just got the phone today and successfully rooted it and I wanted to see what this xposed framework stuff was about I installed the experimental version (tbh did really read it was experimental it was on the front page so I thought it was alright) and when prompt to reboot I did, but now when rebooting I can't get passed the Lg secruity error screen I tried re-flashing back to stock using this thread http://forum.xda-developers.com/showthread.php?t=2799647 but nothing happens after I plug my G3 back in it just says ready is there any other way to fix this security error?
edit:found out that my model number is actually the f400s (sorry i'm a phone noob) for anyone else out there trying to find your phone model it's actually behind the battery

Again I ended up resolving the issue myself and I do not have a picture of the error but I can describe it. When booting my lg g3 the normal big Lg logo appeared then after a bit a smaller lg logo appeared with the words "security error" under it for those looking for a solution to that problem the thread in the op is the correct action to take to resolve the issue. Note doing that wiped everything on my phone which was not a big deal for me but I had to take my phone back the the carrier to input the configuration to access 4g lte again & it unrooted my phone.
i have this same issue can you tell me how you got around it?

jerimynal wiley the error you get "secure boot error" is caused by image you are trying to boot not being bumped or not properly flashed. I assume you get this error both while trying to access recovery and OS. If that is the case you should use this guide:
http://forum.xda-developers.com/showthread.php?t=2785089&nocache=1
to flash stock firmware on your device.
But if you have a case where you are able to access your recovery (TWRP I assume) you could use one of the custom images provided here: http://forum.xda-developers.com/lg-g3/development (assuming you have D855 version) . Flash them and use them as OS.
Thanks man. I actually could get into recovery so I just flashed another kernel

Same here..
Hey all,
I restarted my phone yesterday and it was stuck in a boot loop for some reason. I tried to factory reset, but doing so still resulted in a boot loop. I then proceeded to attempt to flash stock, but the flash tool crashed while during the process. When I try to boot to download mode now, I get "Secure booting error, Error!: Boot Certifcation Verify". I know this also happens on the G2, and I know the process for fixing it. But when trying to use the same method with the G3, I can't access my filesystem from Linux. Any help? Thanks.

I was rooted before updating to lollipop, then tried to back dowk to KK with TOT and this happened, so I dont think I am rooted any more.
The better question is: do you have TWRP (custom recovery) installed? If you do, your phone can be fixed. If not, you are probably screwed.
Basically it sounds to me like your phone managed to flash the updated Android 5.0 bootloader but didn't update the LAF image (download mode). The old download mode doesn't work on the new bootloader, it gives the error you are experiencing.
Because you still have a LAF partition, and presumably a recovery partition (even if they are not working) you cannot access fastboot mode.
In other words, there may be no way to fix your situation.
As the hardware is fine there must be a method, but it might be something only LG can do.

I'm in the same situation now.
I was bumped with TWRP and CM12 installed. I wanted to unroot and go back to stock. Started a flash with LG flashing tool, but it was taking ages, so I unplugged the USB cable in the middle.
Now whenever I boot via either VolUp+USB or trying to get into a recovery I get secure boot error.
Is there a way to fix this ? Or do I need to send a phone to LG ?
This has happened to me today. Downgrading got stuck at 3%. LG Flash tool said to remove phone and plug back in. Any way to fix
Also, does anyone know if downgrading voids warranty or anything?

I didn't find a way to fix it, so I've just sent it to LG repair shop. They haven't yet looked at it so I don't know how much would it cost.
People just tell the service center that you were upgrading from KitKat to Lollipop when the problem happened
Evidence wise it support your claim since the OTA from KitKat to Lollipop overwrites the aboot, sbl, laf and recovery partitions and service center people ultimately cannot tell between failed OTA and a failed KDZ flash

Did you get an answer on the cost yet? I have the same problem, so I'm probably looking at the same resolution as you.

solution for no download mode
Hi guys.
If you cant enter into download mode then you need to force your g3 in to qhsusb bulk mode by shorting the test point.
When you short battery must be removed.
After short your phone will be detected as qhsusb bulk mode.
Send me msg in pm for further help.
If u dont know the test point then let me know.

these devices have locked bootloaders. how did u install twrp?
best bet would to be to find what ever firmware device was on and reflash it with lg up or flash tool if u still have download mode.
Thanks for your reply.
I really don't know what i did to install twrp.
I try to use flash tool but doesn't detect my phone.

@imider I have the same problem trying to recover from a hardbrick on H815. Tell me what happens if you pull battery, plug bag, hold VOL DOWN and insert USB. Do you get fastboot?
EDIT: You might be able to flash it in FlashTool (I said no before) because I see you have Official Status not MODIFIED.

Congrat @imider ,
maybe you can share what you did to fix your G4
Hello,
First I wanted to flash a clean rom on LG G4 H810 and I don't know what I did but the flash doesn't work and my phone has a black screen even the logo is not displayed.
When I connect my phone to my PC (windows 10) it's detected as "Qualcomm HS-USB QDLoader 9008".
Now this is the step that I follow to repair my phone :
1) I follow this tuto : https://forum.xda-developers.com/g4/help/lg-g4-bricked-qualcomm-hs-usb-qdloader-t3609999
2) After that I can enter download mode
3) I flashed a tot with LGUP
I hope it will help.
