Phone stuck in Bootloop - G2 Q&A, Help & Troubleshooting

Hello,
I have a lg g2 d800. I was trying to flash the latest cyanogenmod 13.0 snapshot. I was on cyanogenmod 12.1 the older june snapshot. I booted into recovery and stupidly did not make a backup because I am an idiot. I did a reset before I flashed the rom ( system, cache, dalvik). I flashed the rom and gapps and there were not any problems. I try to reboot the phone and it is just stuck in a boot loop. I have twrp installed. I can access twrp fine. I just need some tips on getting a different nightly or snapshot (I will probably use an older 12.1 snapshot) onto my phone to flash it.
Thanks in advance.

CM 10.2 Google logo loop

I did a clean wipe, regular recovery procedures and flashed the latest 0819 nightly of CyanogenMod 10.2 yesterday, but after restart, my phone is just stuck with the Google logo loop. I did go from CM 10.1 with the latest TWRP.
What should I do to solve the problem?
Restore your nandroid backup, or flash another rom thru recovery. I had the same problem franco's kernel was causing the boot looping issue

Weird boot loop issue after flashing CM 12.1 nightlies

I have a D801, nothing terribly unusual about my setup. But every time I flash a CM 12.1 nightly it gets stuck on the CM boot anim on the subsequent boot. I'm using @blastagator's TWRP 2.8.7.1 and I make sure to wipe cache & dalvik every time. A reboot doesn't help but reflashing SuperSU via TWRP seems to fix it. Anyone have any ideas?

LG G2 not booting after installing 6.0 ROM

Hello, I had some issues with my LG G2 while attemping to flash a new rom, here's my problem:
I checked for the latest crDroid 6.x rom and the gapps, everything went fine, I flashed the rom with no problems at all and then continued with the gapps. But here's the problem, when I tried to boot it, nothing popped out from the display, just the LG logo, then it was completely black. After trying to install another custom rom (cm 13 nightly), nothing happened. Then, I tried to go back to my AICP rom. I had to use ADB installer since I didn't have any zips avaiable, but when I tried to install tk gapps (downloaded from the AICP forum), Error code: 20 came out. I did a research, and this looks weird, because that error only pops when the gapps are not compatible with the current rom, but clearly they were. Any ideas on how to fix this up?

Click to expand...
Click to collapse
for your rom to boot you need hybrid bootstacks
wipe all/flash hybrid/ go to main menu/ then reboot into recovery from recovery/ once in recovery again proceed to flash rom and gapps.
use the one for your variant

Trouble changing recovery and ROM

Hey guys,
I'm having trouble updating both my recovery and flashing a new ROM.
My bootloader is unlocked and I'm rooted, currently have TWRP 2.8.7.0 and the final release of OxySlim 2.2.0 - http://forum.xda-developers.com/oneplus-2/development/rom-oxyslim-t3278169
Whenever I flash a new recovery via adb/fastboot I just get stuck on the One+ bootscreen.
I have to reflash 2.8.7.0 to get access to recovery again.
I've been trying to move to Seraph's ParanoidAndroid here: http://forum.xda-developers.com/oneplus-2/development/5-1-1-paranoid-android-5-1-t3205522
Or to Grarak's CM 13 here: http://forum.xda-developers.com/oneplus-2/orig-development/rom-official-cyanogenmod-13-t3392278
I've also tried flashing Seraph's HybridRecovery 3.4 with no luck.
Am I missing something? I flashed all the version of OxySlim with no problems.
Quick update.
I've flashed halogenOS: http://forum.xda-developers.com/oneplus-2/development/rom-halogenos-oneplus-2-t3377799
It booted up but I couldn't select a language... strange.
So I tried to boot into recovery and it stuck on the boot screen.
I've now flashed the latest TWRP (3.0.2) and it's working. Currently doing a full wipe and trying halogenOS again.
