[Q] LG G3 security error

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

LG G3 D855 Wont boot in Download mode.

Hi im new to XDA Developers Forum, i just tried this Solution( http://forum.xda-developers.com/lg-g3/help/help-secure-boot-error-trying-to-boot-t3054977 ) and my LG G3 D855. Is in the same state as from User "DonnieDoezoe"
"Totally bricked my phone with these instructions Won't turn on anymore. Tried everything...only shows a trinagle if I connect to usb without battery."
Before i tried this. I had already rooted the LG G3 D855, and after these instructions i tried to reboot into recoveryTWRP( wich i flashed with flashify) i tried to reboot with Quick Boot (Reboot ).
After this my Phone doesnt work anymore and is just like in the state of a blacksreen( the phone is visible as LGE AndroidNet USB Serial Port(COM41), the only thing that shows is a triangle if I connect to usb without battery.
I searched for solutions the whole day and tried to unbrick it with the LGFlashTool by flashing the .tot file and .dll, but wont work because i cant enter to the Download mode.
I Hope some one gives me hint in the right direction on how to fix this problem, would much appreciate it.

Need help to unbrick an LG E986

Hello,
I had rooted and then installed free gee app.
Managed to install a cyanogenmod 12 version on my LG but while rebooting i was unable to type my phone pin , the screen just went popping . with another sim card with no code pin , the apps seem to work well ...
I then decided to revert back to a custom rom from LG ; While using LG flash tools, at 98% of the flash, the phone just suddenly went blank.
When i charge there are no lights and it's impossible to get download mode.
I brought the phone to a shop and the technician told that he could not download anything to the phone and was proposing me to send it to "LG" with additional fees without any warranty of recovery.
i have read on the different threads but so far i have not found any solution , all suggestions are welcome
Thanks.
Hello,
When i connect my phone to my windows PC, a device QHSUSB_DLOAD appears but i can't manage to assign a driver to this device though i manage to install the unified LG windows driver.
When i launch LG flash tools, the program is aborted because the phone is not visible.
Looking forward to a repair procedure wit the local LG center.
Thanks for any help.

Bootloop after lg bridge

After modifying build files failed, G4 bootlooped at starting logo.
Tried to repair it with lg bridge, and it was forced to update to 6.0 v20c.
Flashed it with v10fkdz(5.1), and the error message was shown:"Error Code=0x2000, Can't decide current device mode."
Can anybody help me to solve the problem?
I think you broke your download mode; sadly, it is the only mode that you can flash via LG Bridge and LG UP. If you have an unlocked bootloader, you can flash an image through fastboot. As for me, I can't flash on either of those programs since I also broke my download mode and I have a locked bootloader. Otherwise stated, I have a hard bricked device. Waiting for some possible new program to fix my device
I tried on 3 different PCs, and another available G4 device.
The problem is still there.
I don't know why,
but after reinstall LGUP, downgrade of my phone is OK.
Thx guys
