[HELP] DemiGod Crash Handler : Kernal Crash (Can access recovery)

Phone Model: AT&T LG G2 (D800)
Recovery: Custom TWRP Recovery
ROM: CM12 Official ROM
My phone was working fine from last 3-4 months, until today it restarted and got stuck on 'LG' logo, I left it for some time and it shows the demigod green screen of death with option to access download mode and restart.
What I already did!
1) Full hard reset, I can access the TWRP.
2) Flashed the ROM again.
Current Situation!
Stuck on LG logo from last 10mins.
Thanks in advance.
Edit #1: Reflashed the same ROM (CM12) and it booted into the language selection page, freezes and restarted. Stuck on black screen, I turned it off by pressing the power button for 10-15 secs. I kept it in a freezer for 10-15secs and turned it on, same happened.
Edit #2 I flashed a stock based ROM through TWRP, it was going fine but it froze in between, I waited for some time and it went black. I waited for 1 hr and it was still black so I hold the power button and restarted the phone.
Now its showing "Secure Boot Error" which remains for some secs and a black screen comes, I can't open TWRP, Download mode is accessible but after 2 secs into download mode, secure boot error comes. Whenever I try to connect it to Windows PC(I installed all the required drivers and all) it starting popping up drives(with option to format) which never stops until I remove the USB cable.

Steps to perform.
1. While in critical error screen you have an option to press volume up button to boot into download mode( although it will not boot to download mode) but still press volume up button so your Pc can detect your phone.
2. Now flash a kdz file of your lg g2 with flash tool. ( you can google for it to download flash file for your lg g2 and how to flash it with lg flass tool.)
3. When you will try to flash it will fail..
4. Now power off your phone by pressing power button.
5. Now boot to download mode and flash the correct kdz with lg flash tool and u r good to go..
To acess download mode power off your phone immediately press volume up button and while keep pressing it and plug in usb cable and you will be in download mode
I performed all this on lg g2 d801 but i hope u can try it on other varients as well. As i was scared of short circut method and srk tool didn't help..

Thanks for replying.
My case is a bit different now, I reflashed the same ROM(CM12) and it successfully booted, worked for 10 secs and it was frozen, restarted automatically, stuck on LG Logo.
I notice that there's some heat issue, I kept it in freezer for 10 secs, rebooted it, it booted till language selection page and freeze after 10-15secs.
Also the link is for DemiGod Critical Crash, mine is DemiGod Kernel Crash.

First post updated, please check the current situation before posting anything.

I don't have a computer or laptop to connect it to so how can I fix it?

LG G2 D802 No recovery/ No Donwload Mode/ No Fastboot

Hi Guys,
I got my G2 back from my brother who have not using it for a while.
1st day it was working. I plan to install Lineage or custom ROM today...thats when the issue start:
1: it wont go to recovery mode. Even thou I have rooted and install latest TWRP it will only boot to Hardware control key screen, only this screen and wont boot to the OS it will be stuck on LG logo forever....
2: tried to go to Download mode....the same It will go to the same hardware control key only....
3: when I plug in to my PC it wont turn off, keep on restarting after I press the power button for a while.... only if no cable connected I can totally turn it off...
For a noob like me....looks like my G2 D802 is brick :crying: ...any suggestion?
PS: windows detect it( As below picture ), off at all when I plug in AC.....It Will just show the LG logo and the LED just flashing non stop until I pull out the cable and turn it off...
This is what shown on the laptop No Disk1/2/3/4/5 of sort showing on the Device Manager and on the phone each time I try to go recovery or download mode belowh happen:

https://flic.kr/p/2bs67ne

Update 1: I found out why the phone was brick. Seems like my Brother ask his friend to install Lineage 15.1 on the it. After everything is verified ok. He wipe and try to flash the rom in TWRP but.....it failed and suddenly just freeze and turn off the screen. Maybe bad ROM download or some step miss....so now the Phone has NO OS and would not boot to anything only the Hardware Key Management....that's all....help? Need the phone as 2nd phone for company lines....dont wanna take the iPhone 6 from my boss....

help?
