LG G2 stuck at lg logo whenever i try to flash a kitkat rom - G2 Q&A, Help & Troubleshooting

It's like the title says. Currently I'm on CM13 with the Lollipop bump bootloader. I tried to flash Slimkat and pac 4.4.4 and the result is the g2 gets stuck at the lg logo and the lg logo disappears and reappears over and over. These are the steps I did:
1. Backup my rom then did factory reset
2. Flashed the bootloader changer, flashed the JB bootloader
3. phone rebooted back to twrp
4. did a factory reset again just in case
5. Flashed a KitKat ROM then flashed Gapps
6. Rebooted phone
And the rest is that the phone just bootloops with the lg logo over and over. What am I doing wrong? The bootloader changer guide says for KitKat custom roms I need the jellybean bootloader and that's what I flashed. Am I missing something here?????

Bricked LG G2 D802

Hi Guyz, so i managed to brick my phone yesterday. Was running Optimus G3 and decided to flash CloudyG2 3.3. Followed the instructions did a full wipe but when rebooted LG logo would flash for a split second then screen goes blank. The screen is on because can see the back-light but nothing boots. Tried a couple more restarts but the same thing happens. I did take a TWRP backup prior but when i enter recovery mode and restore the backup, when it reboots i get the LG logo then the android animation but then it freezes/stops on the Android text.
I then tried flashing stock rom via LG Flash Tool, downloaded both kitkat and lollipop kdz files, entered download mode on phone and got the firmware update message, went through the process of flashing with the flash tool but when it comes to the software upgrade part, it gets to 2% then fails. with a message - Upgrade stopped due to an error. I get this message when trying to flash both kitkat and lollipop kdz files and i have tried on both windows 10 machine and windows 7 laptop.
As i have access to recovery i have tried restoring backup many times but it just gets stuck at after the android animation, i guess my next step is to try the tot flash method but im struggling to find a clear guide on how to do this so any advice would be helpful.
Cheers, Justin.

Thanks, actually shortly after i posted question it fixed itself... i tried flashing lollipop again, the software upgrade started and it got to 2% then error. I left the LG flash tool open with the error on screen, disconnected phone and rebooted the phone... it went past LG logo and got stuck in boot just after showing android animation, so then i plugged in phone (wanted to see if could access phone via windows whilst stuck at boot) and after a couple of minutes the software upgrade window started on my pc so checked phone and it had switched into Firmware Update mode and was updating... so all good now!! Lollipop has installed and phone all working.
^^^ This may help someone with similar problem.
Thanks,
You should've flashed the kitkat bootloder before.. If you want to go back to cloudy ,flash the kitkat bootlader again..

Stuck at room boot animation, no recovery mode

I have installed Unofficial CM 13 successfully, but I forgot to root the device, so I go back and flash supersu file and reboot - I think I flashed wrong version for marshmallow. now phone stuck at cm boot animation, I have no recovery, only has access to download mode. I also have no access to phone through adb or fastboot.
I was in the similar situation before, where I was stuck at lg logo, and fix it by flashing stock rom (now I cannot find that thread), but now it tries to boot the rom, seems like a different situation.
What should I do?
