[Q] Boot loop and broken bootloader - G2 Q&A, Help & Troubleshooting

Hi all,
I have a LG G2 that is on Cyanogenmod 12 (nightly) and has TWRP 2.8.6.0 as a bootloader.
I did a factory reset in Cyanogenmod, what I clearly should not have done..
Now I'm in a bootloop and I can't enter the bootloader. I can come as far as going to TWRP. But the blue screen of teamwin boots up and it just crashes after that and tries to start TWRP again.
Is there anyway I can fix this issue? Perhaps with adb or something else?
Some help or link to a tutorial would be great. I couldn't find a fix to this problem.
Regards,

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?

LG G2 D802 32GB - After Installing Desparate ROM cannot boot in Recovery TWRP

This is my first question post, so if I say something wrong don't please don't misjudge.
What is my problem.
1. I rooted my LG G2 D802 32GB.
2. I installed TWRP.
3. I installed Desperate Rom (http://forum.xda-developers.com/lg-g2/development/rom-desperate-rom-t3437472) through Recovery TWRP, which is very awesome .
4. The ROM is working fine, without any problem but when I'm trying to reboot in Recovery TWRP, it doesn't. After LG logo it says "error: Boot certification verify"
How Can I solve this?
I tried some methods but nothing.
Can you please help me???

Got my Lenovo A1000 stuck on a boot loop with no access to recovery

Hi. Basically, i tried flashing TWRP via Flashify and apparently something went wrong because i couldn't go into recovery from that point on (i think i've tried every combination known to mankind, unless there's a really special one that i'm missing). The problem is, that like a complete idiot, i tried flashing CyanogenMod 12.1 from Flashify as well.
As you'd expect, it didn't go too well and now i've got no access to the phone. It can't get past the logo screen and won't boot into recovery either. Is there anything that can be done via PC i guess? Thanks in advance

iam a complete fool now I am screwed I don't know what to do. If you know any method to solve this plz help me .......... thanks in advance

SM-T555 Bootloop

Hi
I have tried to flash TWRP to my sm t555 but now i got only bootloop on samsung logo.
After that I had flashed stock recovery - but still nothing.
OS - 7.1.1 - Nougat
I can go to download mode
after going to recovery mode - hang on samsung logo and shut down,
after normal boot - bootloop.
What can I do?
I have the same issue after trying to root.
Did you find a solution?
edit:
I managed to succesfully flash TWRP from this thread, however it didn't resolve the bootloop problem.
edit:
I wiped everything and flashed official ROM, this solved the problem. Then I rooted using different method

OP5 bootloop issue

hello,
after following instructions to unlock bootloader, flash custom recovery, and root, i have gotten stuck with a bootloop. The issue started after trying to install Magisk.
I can boot into TWRP 3.2.3-0 and have tried many recommendations but do not seem to be able to boot into OS. I just get the constant boot animation.
thanks
edit: fixed
