Security error LG G2 - G2 General

hello,
After installing Paranoid Android 4.6 Beta 5 on my LG G2 , I made a false manipulation in TWRP .
When my start as the LG logo appears with "Security error" display and then turns itself off . I do not have access either to recovery or to download mode.
I tried to follow this tutorial : http://forum.xda-developers.com/showthread.php?t=2582142
But from the beginning there was a problem :
Thibaut .

Try to press and keep pressed vol up + power button.This need to get you to Download mode,then just flash stock.
P.S.-Let me guess,Bump!?

Go to the unbrick thread for a guide, you may have screwed up your partitons.

If you can get in emergency mode but the app doesn't recognise the phone, you've most likely bricked your phone.
Try the shaking tip or reinstalling the drivers or something.
Install the USB drivers that come with the LG Air Suite and LG Update Tool.
i cant get pass by the lg logo ...thats it...it dies there and the pc dosent recognise it...when i plug it into the usb it keeps looping ..
so the main thing is why dosent it starts ...ive only killed the custom recovery ...i had void installed...so why?
Try holding Home + Vol. Down + Power. This should do a factory reset / boot custom recovery.

le and yes the shake thing + all the keys pressed ..i dont know witch one ive pressed worked !
The only thing you can do from emergency mode is use the KDZ Updater or try using the LG Update Tool.
Set the KDZ Updater to EMERGENCY and CS_EMERGENCY mode. Try also changing the phone type, there are several.
Sometimes the Updater doesn't recognize your device. You should try again.
Other options include buying a dongle box(SpiderMan Box, Vygis Box, Infinity Box...).
And off couse - LG Service. You could always blame LG if they don't have proof that you messed your phone yourself...
i`m home...and it still dosent see the phone..:|
What do you mean by "I'm home?"
If you have managed to restore/reinstall android simply install LG Air Suite IV.
If you haven't, install only the drivers.
i mean i was away....and im at emergency mode...and i it still dosent sees the phone
ive downloaded the drivers...installed them and nothing
still dosent see the phone....adb shell says no device found kdz same
le ...so i tried to make it back to emergency mode...it dose see the little brat..it just installed 3 usb drivers named LGE ...but kdz still is useless
Try a different USB port or plug in another device in this one to see if it works.
Also see if the phone charges when you plug it in the charger - if not, buy another cable.
so the pc installs the drivers but kdz says that the port = -1 and the phone was not found

after playing some images in my head like smashing my phone torching it and then removeing his battery and when the sound of usb plugged in hitted the launch button in cdma emergency .. it kinda writes..

Did I just brick my new LG UK410 US Cellular

Hi, all
I was running kitkat on my tablet so I decided to flash with CM13 custom rom I used DP TOOLS to rooted my tablet after that I used Flashify to installed TWRP at that point everything were nice and happy, then I installed gapps-600-base-20151112-1-signed.zip, cm-13.0-20160604-NIGHTLY-v410.zip, BETA-SuperSU-v2.74-2-20160519174328.zip using TWRP at that point everything installed without any error, I rebooted the tablet and now its stuck to LG logo with "error boot certification verify" after pressing power and volume up button I was able to get in download mode, but DP tools doesn't recognized tablet using my PC so I'm wondering how to installed rom back again since I cant get TWRP to load and why am I get this "error boot certification verify" anyway. Any help will be very helpful. Thanks
i fixed it using these steps, Thanks
1. You will need the Stock Rooted ROM: [ROM][STOCK](V410 ONLY)KOT49I.V4101d | 4.4.2… | LG G Pad 10.1 | XDA Forums
2. Stock Recovery Image: https://onedrive.live.com/redir?resi...int=file,img
[OPTIONAL]
- I downloaded the USB Driver suite so I can make sure it all connects and works, this really is optional, but I would HIGHLY suggest it!
LG Software & Firmware | LG U.S.A
- I also download this nifty tool called DP Tools by danielpinto8zz6 over at XDA. This just made it a lot easier to reboot to recovery and all that fun stuff.
[Tool][Win] DP TOOLS - Manage your LG device | LG G Pad 10.1 | XDA Forums
[MANUAL RECOVERY]
If you do not want to install the drivers and DP Tools, you can reboot to recovery using the following method:
1. Power OFF your device and unplug from USB
2. Press Vol-Down + Power and HOLD until you see the LG Logo (will only take a couple seconds)
3. Let go of the POWER button ONLY
4. Keep holding the Vol-Down, then also press Power + Vol-Up (so you should now be holding ALL 3 BUTTONS)
5. Wait for recovery mode to start and you can let go of the buttons
[THE PROCESS]
1. Copy the ROM and Recovery Image to to SD Card or Internal Storage of your device
2. Reboot to Recovery
3. Wipe, Wipe, Wipe
4. Flash the Stock Rooted ROM
5. Reboot and set up your device far enough for you to get into the Play Store and download an App
6. Download Flashify: https://play.google.com/store/apps/d...llner.flashify
7. Launch the app and flash your stock recovery
8. DO NOT REBOOT YET (however, if you do reboot, it's really not an issue)
9. Open the Super User app that is already installed
10. Go into Settings and then find the In-Root (Uninstall) option and you will get a warning that Root will be removed
11. Complete the instructions on the screen and you are now back to stock
[TROUBLESHOOTING]
- If SU will not uninstall and just hangs, restart the device and try again
- If the ROM starts acting strange, Factory Restore (this did not happen to me, but happened to a friends and reset fixed it all)
Please let me know if anyone has any questions!!
Thanks!

Please help!!! Lg G3 stuck in system recovery screen

I used BoardDiag after being stuck in a loop where my lg g3 VS985 had the led flashing with the screen black every time i restarted and my device came up as Qualcomm. I feel like I got closer to fixing it after using BoardDiag. Now the lg logo pops up for a few seconds, it shuts off, comes back on and enters system recovery. It keeps doing this. It pops up as LG in my device manager only for the few seconds the logo appears. If I try to hold the volume up button it puts me back into Qualcomm. I know the next step after Boarddiag is lg flash tool but I get the model information check fail when using the stock dll and tot. There was another dll file that worked for people but for me it gives an error. In the system recovery I have already tried doing a factory reset to no avail. It gives me the option to update through external sd card , cache, and adb. I have adb all installed but I'm too new at this to know how I can just restore it to stock. Please help!! Thank you!
Can you get the phone into download mode and do a standard KDZ flash?

If I try to put it in download mode I get a black screen and my pc recognizes it as qualcomm. If I boot normally it will see it as lg only for the few seconds it shows the logo. Also while stuck in recovery mode I have this error:
[Recovery.cpp][main()] ################# factory reset start ###################, Thu Jan 1 00:00:39 1970
an:6585214
target = mmcblk0p44

[shs0917] just_exit: 0
Also how can I flash it? Especially from recovery screen. Sorry new.
Do the download mode and get it recongized as Qualcomm and fire up BoardDiag. From there, I have some files that may help. Unfortunately, until AFH (Android File Hosting) approves my dev access, I only have a ****ty server to host them and so I will only give the links out by PM. Standby and I will PM you what you need shortly.
My little antibrick toolkit just passed it's first trial.
The OPs problem was solved via PM. I will be sharing these tools shortly.

That is encouraging for those of us who have yet to make the attempt to rollback and root our device. [emoji4]

Flashtool\unbrick help LG G2 Mini D-620

Edit: I managed. Thanks anyway!
I done goof'd when trying to flash custom recovery, now phone gives "secure booting error! Cause: boot certification verify" when trying to boot.
I'm unable Fastboot - all the tutorials I found give me wrong instructions (*more details at the end).
So I'm trying to flash stock rom, but every flashing software I tried either had a broken download link (LG's official site is hot garbage), Needs a password (seriously, why), or doesn't run on my perfectly fine, modern enough PC (Ryzen gen 2).
Any help? With either a normal Flashtool (please link), or a way to enter Fastboot?
*Volume+ power, release when logo appears, then holding down volume+power again brings me to factory rest. Not even recovery. Choosing "Yes" on factory reset does nothing.
*Powering off, then holding volume up while plugging in the USB brings me to download mode. Keeping the same butting still held does nothing.
*Powering off, then holding volume down while plugging in the USB does nothing (boots normally, then displays the booting error I mentioned earlier).
I have similar problem with LG G2 mini: Secure booting error: Boot certification verify. I tried turn on download mode but I can not turn on download mode. I tried t flash smartphone by flashing software LG flash tools but this program hangs. Exception code: c0000005. Can you help me?
