Secure Booting Error - AT&T LG G2

I did a factory reset on my LG G2, wiped it completely clean. It boot up just fine and then i went to the software updates that are on the phone and applied them. When i restarted my phone it gave me this error -
------------------------------------------------
ERROR : boot certification verify
Secure booting error
Cause : Boot certification verify
------------------------------------------------
I have been looking for a fix for this, and i have found many threads on the topic. My issue is that i can not boot my phone into any mode. I try to boot it into any of the modes such as Recovery mode, Fast boot mode and Download mode and none of them work. I just get the error again and then my phone shuts off. All of the threads that i have found on this topic revolve around being able to boot your phone into one of the modes given, and i just can't. So please, if anyone can give me some advice or point me in the direction of a thread for this i would be very grateful.
Also, I did find a link on this website that i thought would help me, and i went to download some of the software that he had linked in his thread and it riddled my computer with adware/malware. I can't remember the link to the thread but if i see it again i will know it and i will report it.
Thank you in advance for any help!
EDIT : My phone does not show up in my Device Manager on my pc.

if anyone even stumbles upon a thread please help me out with a link. I am still looking and still coming up with nothing.

[Completed] Soon gonna cry

Hi I've been searching for a while now but I can't find a topic on this yet.
Recently it rooted my phone but now when I try turning it on it gets stuck at the loading screen, ok. Now then I managed to get to the boot loader from here I go to the recovery option,now here is the problem when I select the recovery option the phone will either go back to the boot loader or will not turn back on. Also in this state my PC cannot see my phone as a device. PS I cant even get to the error screen most people seem to get when they go to the recovery option.
Any help will be much appreciated.

[Completed] Recovery mode is gone, Factory mode is gone, help me XDA you're my only hope...

So here is a string of steps I've already been through in trying to save my bricked Nexus 6: [Can't post outside link yet...]
Basically I got the 'your phone is corrupt' message from google and it kept forcibly shutting down. It would not boot up so someone suggested I side load a rescue OTA. At this point recovery existed and I went through all the steps and had it installing, only to fail mid-way through (~52%) and give me a 'read error' on my command prompt. I started the whole process over again just fine and it got to 73% before 'read error' failing again. I thought no big deal, I'll just keep doing this until it gets to 100%. Nope, recovery is gone. I cannot get there anymore. I start into Fastboot mode and scroll to recovery and hit power and it just goes to a new Fastboot screen and keeps flashing every time I try to select it. The Bootloader logs give me a 'failed to validate boot image: ret=-1' message and says 'Boot up failed.'
I can't find a single guide online that doesn't require recovery mode to work. At this point I don't care about my data and just want to get this phone working again before I throw in the towel and pay Motorola $175 for a refurb. I'm just barely over a year too. The Nexus 'expert' gave up and blamed the memory and maybe he is right but I wanted to run this by you guys first. This phone was completely stock and unrooted.
The only reason why I feel there is still a chance is because when I connect USB my computer reads it as an Android Device in Device Manager with 'Android Bootloader Interface' as a sub device. If the computer can read it, isn't there a chance that some kind of software exists that can forcibly load a new bootloader onto this phone without recovery? I'm 'competent' with computers and android phones but I haven't rooted or done any custom stuff in years so I'm at a loss for what's out there.
Thanks in advance for any help you can give me, even if it's to tell me I'm SOL.
Ok so far I have tried to load a custom recovery but that requires an unlocked bootloader. Then I tried using a toolkit to flash stock as a soft-bricked device but that also requires an unlocked bootloader and I can't unlock the damn bootloader. You know, I thought I was just playing it safe by leaving this phone as-is instead of playing around with it but it looks like I screwed myself by doing so.

Heyaa!
That happened to me as well, I was so excited when I got my new S7 That I didn't realize I was using the Recovery for the "Qualcomm/Snapdragon 820" edition of the S7 when I had the Exynos Version. I also tried countless of times to reboot the phone but heres what you do.
Just force reboot the Phone to enter download mode, It took me alot of tries to get it working until after force rebooting the phone alot of times it eventually entered download mode. Once it entered download mode I wasted no time and I flashed the PROPER RECOVERY for my S7 Exynos.
Make sure you are using the correct TWRP Image, and did you have OEM Unlock checked in Developer Settings before installing recovery?
Please read THIS it's what helped me fix my device!
Kindly update me if something happens
Godspeed!

Thank you for the answer!
I have the phone beside me for 2 days straight an I try it multiple times but i cant get it into Download Mode. Is there any way to smhw force it into it without trying?
Beside that: I rooted it multiple months before and it worked like a dream... it just went black that day (it got charged in that moment, no input came in any way) and since then this problem occurs.
Ill keep trying!
If it happened all of a sudden, I've read some users from reddit brought it in to Samsung. If it won't get into download mode no matter what you do, I believe it might be an emmc failure. But hopefully its not

Bricked unlocked device

Hello,
I recently unlocked, flashed TWRP and flashed Pixel Experience onto my Mi Mix 2s. After some time a notification of an available update appeared. I tried to install it but it didn't work. After some troubleshooting it appeared that I couldn't get my device booted into TWRP recovery mode.
I tried reflashing it via fastboot but that didn't work. It did not give any errors upon executing the command lines in the fastboot command prompt but just nothing happened. It just sat still like it was waiting, and waiting, and waiting.
So i thought, let's just reset the phone via the normal settings menu in Android. In hindsight that was quite a dumb move I guess, because after all the phone used to be working. But still I followed through and now it wound up in a bootloop. I can still get it into the bootloader mode, and in fastboot it shows my device when I execute <fasboot devices> but flashing or erasing the recovery doesn't work. It looks as if it sees the phone, can get info from it but is not able or allowed to flash anything to it. But it doesn't give any errors, it just seems to keep waiting on something, I don't know.
I hope any of you guys can help me because searching this forum or googling hasn't helped me getting any further. All topics I found at least had some errors in fastboot/bootloader mode which gave them a direction to go into...
So please help me!
Whoops, I solved it myself. On another laptop it magically worked the first time. Probably an issue with either the USB port or the drivers.
