Unable to boot roms. - Sprint LG G2

Hello,
First time posting
I have a major problem with my G2, every single rom I have tried except for stock ones do not boot at all.
I have TWRP 2.8.5.0...(I think...) installed on my device and it boots into TWRP just fine. So I push over a rom file of any sort. Install it, and no problems in the terminal. I go to reboot and the device will go to the LG logo and then quickly go to a black screen. I can reboot the phone and the same thing happens every time and with every rom I can find for the device. The backlight on the phone does stay on while the phone goes to the dark screen. And a few oddities have happened when it goes to the black screen. 1. When plugged into my Linux machine the black screen will flash in a regular pattern until rebooted. And 2. When plugged into my Windows machine it will mount dozens of partitions and drives for some bizzare reason. If anyone can help thanks a ton. If you need anymore info just contact me.

same for me i tried a lot of custom roms but no one of them worked i could manage to make my phone back to stock but couldnt flash any costom one.
LG G2 LS980

[Q] Help! Unlocked bootloader, installed CWM, now phone won't boot

I used the GN Toolkit V2.2 to unlock the bootloader, after installing the adb drivers via PDANet. I flashed Clockwork Mod on as well, and was going to install the Android Revolution ROM. I thought I had already copied the zip file to the internal storage, but when I tried to flash it from inside CWM, it said no files were found. (May have copied it before wiping device, I can't remember). So I restarted so I could copy the zip file again and then flash it. However when starting, it seemed to be stuck on the startup screen, with all the flashing blocks of color fading in and out. After a while stuck on there I couldn't do anything so I did a battery pull to restart. At this point, I can start normally or into recovery mode. If I try to start normally, (or go into recovery mode and choose restart from the submenu), it shows the black screen with the white Google logo, and the unlocked icon, stalls for a few seconds, then does a short vibrate and reloads the logo again. It will keep doing this and not go any further. I tried doing an additional data wipe from recovery mode but that didn't help, and I tried to do USB mount from recovery mode, hoping to copy the Revolution zip file and flash it over, but it couldn't mount. I'm starting to panic a little bit, did I brick or otherwise mess my phone up? What can I do? Any help is REALLY appreciated.
Thanks so much and I hope this is the right forum.
I dont have the answer but I wanted to post to calm you. This happens a lot.....multiple times to me on my android devices. You live and learn next time, do a backup in cwm before wiping data and flashing new stuff
Im sure someone will post shortly to solve your problem
Well ok that is reassuring thanks. I downloaded the Google factory ROM from the code.google.com and was able to flash that on my phone with GN Toolkit. It is trying to boot right now, still on the colorful screen. I think maybe I didn't give it enough time last time around? At least I'm past the black and white logo screen. So I'll let it sit for a few minutes and see what happens.
Edit: I let it run for a couple minutes, and it blacked the screen for a sec, showed the white Google logo again, and then went into the colorful startup screen again. I think it's working now so that's a relief.
If someone finds this thread in the future with a similar issue: Don't battery pull during start up and be patient if you don't want to freak yourself out haha. But as spitefulcheerio said, it will be okay so just don't panic. Thanks again.
Make sure you do a Factory Reset in STOCK recovery after unlocking the bootloader. THEN install CWM. learned that one the hard way. skipped a step after doing the oem unlock.
Yes, first time will take awhile on the boot animation.
And, as long as you see the google logo, you are ok, even if it freezes on that. They designed this phone to be easy

Guess all I needed was a psychological confidence boost, thanks for everyone for being supportive I thought I just threw a few hundred bucks away. But I got Revolution installed, phone and rooted and runs like a dream. Thanks all around!

To provide some technical details on why it takes longer the first boot and appears to "hang" at boot animation ...
During the boot animation, the /data/dalvik-cache directory is built up for each application loaded on the device. This occurs during the very first boot. If the /data partition is wiped, the dalvik-cache directory is also wiped and will have to be rebuilt on the first boot. All subsequent boots will be quicker as this directory has already been populated.
Whenever loading a new ROM or performing the fastboot oem unlock command, the /data partition is generally wiped which takes with it dalvik-cache and results in the delayed initial boot time while the dalvik-cache directory is re-populated.
Hope that makes sense and fills in a few blanks on the why Android appears to "hang" at the boot animation during first boot after the /data partition is erased or the /data/dalvik-cache directory is erased.

[Q] Screen Issues Lead To Bricked Device

I was trying out using a keyboard with a cheap USB OTG cable, and all was good. Then all of the sudden the screen went buggy, where ever other line of pixels was shifted to the left or the right, almost like some sort of corrupted video file. It started to reboot itself, and it got to the black screen with the Google logo and then the screen fuzzed in the same way as before. It then starts to reboot and does the same thing over and over again. I find that I can get to the recovery screen with the scroll arrows. From there, if I tell it to reboot into recovery it goes back into the same Google logo bootloop. I then went back to the original recovery screen and I decide to try out adb to see if it works. Sure enough it does, and I unwisely start flashing a stock 4.2 bootloader image. However, while it is flashing the screen does the same fuzz thing and and stays fuzzed. Then it doesn't respond to anything. I take out the battery, and try to restart and with will not turn on at all, no vibration, no light from the screen, nothing. I tried a unbricking methods from there, and nothing can make it come back alive. Any ideas?

Galaxy Note 2: Stuck In Bootloop

NoteII Randomly stuck in a bootloop with no access to recovery
I looked for two days around the web for fixes to this, tried flashing everything from roms (if i understand it correctly it's like a phone OS), through custom recoveries (the things that show up after the up/home/power button combo) and even a kernel. I know that I honestly shouldn't have done that without the full knowledge of what I did, but at 3AM I didn't think much. I think i even tried using PIT, but it got stuck and didn't go through.
Okay, specifics:
One day I pick up my phone and notice the big white letters - " (...) note II" etc, standard bootloop. Kinda surprising since I didn't do anything to the phone, but It had some problems before like deleting like 4-5 apps randomly once, or an icon or two disappearing. I tried the obvious method of recovery mode and clearing caches and such, but it didn't work:
after the button combination it briefly showed the "teamwin" blue logo of my recovery i used to have for like 2 years, and then it goes black, and the white letters show up again. Only the download mode shows up. Odin detects the phone and when i flashed a stock rom and some recoveries on it, odin said they "passed", but no change ensued, the recovery still showed teamwin's, even after flashing clockwork recovery, or whatever it's called. I basically accomplished nothing, and I need to know what to do specifically to fix the phone, without bricking it even more. can you guys point me in the right direction, or maybe try to diagnose the problem? Thanks.
-no recovery
-recovery flashing doesn't change anything
-download mode works, odin detects the phone
I've got the impression that you're trying to make two steps in one. I suggest to flash firmware through Odin, reboot, setup and then make wipes and factory reset in stock recovery. Then flash the custom recovery through Odin and all should be fine again.
Reminder: Don't flash firmware beneath your current bootloader version.

Rooted, TWRP installed. Custom ROMS won't boot

As the title says. As soon as I try to install a custom ROM phone doesn't even reach the LG Logo. Just boots to a log screen, with the last line mentioning fastboot mode (however its not in download mode).
Tried going back to stock and trying to reroot and installing twrp agiain, but no luck. Think there may be a problem with my phone.
Last time I had a custom ROM installed a couple of days, it kept crashing giving me a green screen log.
Any ideas?

random infinite bootloop.

Hello there
After my phone randomly rebooted while watching a video it ran into a bootloop.
I had been running LineageOS for the past couple of months and everything was fine up until yesterday.
I have tried restarting, and everything and only managed to reflash twrp via adb and force it to boot into twrp, but now it's stuck booting into that.
when I try to boot into lineage I only see the boot animation of lineage that never stops, and when I boot into twrp I see the boot screen of that, which never stops.
I've let the phone do its thing for so long that it has run out of power, so it's not something that just takes a long time. I feel like this thing is completely bricked now.
Anyone maybe got a solution? Any help would be appreciated.
Hi,
Think I might have the same issue, except I didn't flash or modify anything on the phone. I'm running all stock ROM and all the rest.
Stuck in a bootloop in recovery mode. Mini partition does not recognise the phone. Same with QPST. QComDloader does, but only for a few seconds, so whatever I try it's not fast enough before the next reboot...
Whats are the options? I don't want to have to send it back to China
