[Q] Should I trying flashing a different rom?

I have a D800, one day I wanted to flash CM12 on it, used twrp flashed gapps and cm12. The phone rebooted but appeared to be stuck in a loop, it finally booted, but turnued off shortly after. The phone occasionally turns on and while it's on randomly turns off. I tried using LG flash tools to revert back to stock (Installed the drivers required from lgs website), the phone goes back to 4.2.2 jellybean and randomly turns off after some usage. I have no idea what I should do now.

Boot loop issues on stock phone

Hello,
My stock Verizon S7 Edge has been stuck in boot loop and won't load all the way to the OS. I even flashed it via Odin and it is still looping. What do you think is wrong with it? Thanks for your help.
Condition of the phone is great except one day it was in a bag in direct sun and got very hot. 2 days later I started having problems. Always had stock ROM.
More detailed version of events:
June: in hot weather, the phone would randomly turn off and show 0% battery. This happened just a handful of times then it was OK.
August: 2 days after getting quite hot in my bag that I left in the sun, it randomly rebooted and got in a boot loop. I tried troubleshooting guides and eventually had to do a factory reset. This fixed the problem for 5 days, but then it started boot looping and wouldn't load to the OS. Factory reset didn't work.
Today: finally got around to installing stock Verizon Oreo ROM via Odin. Started setting up the phone but now it is boot looping again.

S5 SM-901F Bootloop on device with Custom ROM

I flashed the ROM Ressurection Remix onto my phone to get a newer Android version since the model is quite old. Everything worked perfectly for over two years. Then while browsing, my phone crashed and got into a bootloop and restarts after showing the Samsung Logo. After manually removing the battery and putting it back repeatedly it boots up somehow. I couldn't reproduce what was happening back then.
After that it crashes in irregular intervals for no apparent reason and every time I could get it to boot properly by turning off and on for a long period of time.
Now I got the same problem and I wanted to get rid of the bootloop, so I decided to flash it with a new version of Ressurection Remix. I updated TWRP via Odin and had much trouble to get into recovery mode since my phone was crashing at the Samsung logo. As I got into recovery I made a factory reset and flashed the new rom. But as soon as my phone started to reboot after the flashing, it crashes again and the loop starts once again. Again, I searched for another Rom and used LineageOS but the problem persists.
Now I'm out of options, I can't even get into recovery mode by now.
Could anybody help me out?

Freezes on boot animation for 10 secs then bootloops

Hello all,
So I've faced the bootloop of death a year ago on this device and applied the BLOD patch and everything went fine till now. I found my device bootlooping like it happened before but this time it passes the Google logo then starts the 4 circles animation but freezes after 5-10 seconds then bootloops and never reaches the animation again. I tried doing the bootloop fixes with stock ROMS (7.1.2 and 8.1.0) but nothing is working now. The TWRP is running fine so I believe the hardware is fine?
Any help would be appreciated, Thanks

weird bootloop

I flashed a custom kernel recently on my phone that's compatible with Android 10 roms. After the reboot all seemed fine. I waited 30 minutes just like for any other custom kernel then I turned my screen on, the substratum theme I was using wasn't applied then my phone randomly reboot so I let it do so. After the reboot I turned it on immediately and it randomly reboot a few seconds later so I force reboot to recovery to reflash the kernel. It didn't work and now I'm stuck in bootloop so I prepared my phone for a clean flash and did so. After the clean flash Havoc booted up into setup wizard then about a minute into the setup my phone rebooted again(soft reboot) and it rebooted into the setup wizard with the progress from before already done. I gave it about an hour and it kept doing the same thing over and over again so I clean flashed a different rom this time thinking it would fix the issue but the same thing still happens, it's still happening till now and I can't think of any way to fix this
tl;dr
I flashed a custom kernel and I'm stuck with a weird kind of bootloop where it does boot but then restarts a minute later over and over
is there any way to fix this? And if so if I need to flash the fastboot rom can I do it without losing twrp and stuff so I can reinstall my cusrom?
