Lg g4 h811 stuck at boot animation after root - G4 Q&A, Help & Troubleshooting

I made an account just to ask this question because I’m honestly at a loss lol I’ve been reduced to using my girlfriends old iPhone and I miss my G4 ?
Anyways I recently had installed TWRP on my G4 along with the most recent version of Lineage OS on my phone. Not too long after that a new build came out so I updated my phone but I lost root access after that. I tried to root it again by flashing Supersu using TWRP but I guess I messed up a step along the way because afterwards my phone hasn’t been booting properly. It stays stuck at the animation screen after the LG logo appears.
I’ve tried to access recovery mode using the buttons on the phone but it doesn’t work. The only thing I can do is enter download mode but even then when I plug in my phone to my computer it doesn’t recognize my phone.
I feel like I’ve searched everywhere for answers but I’m clueless right now lol I would really appreciate any advice or help! I wanna get back to using my Android this iPhone isn’t the same ? I can provide any other information as needed.

[Q] Bootloop, and factory reset is stuck [SOLVED]

My device is rooted with towelroot, I installed supersu afterwards...
before bootloop I installed fontexplorer, and installed few fonts, it asked me to reboot, i rebooted, and now it just bootloop's all the time, LG animation and vibration, I can't get into fastmode, tried all kinds of button combinations..
When I try to factory reset, after pressing yes it shows erasing, and then it's stuck on boot logo, not animation..
Download mode is stuck also, just shows 0% but at least then pc's device manager shows com device found
How to fix this ?
All this happened after I rebooted my phone, before rebooting I installed few fonts with Font Installer ★ Root ★(com.jrummy.font.installer) app
THIS guide will help, you've softbricked, only in this guide you will of course need the dll and tot files for your phone and not Sprint. As long as phone comes on,computer recognizes it, and, it goes into dl mode, you should be good.

That stinks huh?!
I've been using iFont and Fontster from the Play Store without any issues for future reference.

G3s to me are finicky about changing or modifying. I modified one build prop setting, rebooted, same thing as op, mine wasn't bootlooping tho, but stuck on the big red 2 screen. Flashtool is your only friend at this point.

Wow, I can't believe I fixed it, I thought it's impossible
I just went into download mode and used LG Flash Tool 2014 to flash to stock firmware..

If phone is not sprint, then KDZ method works too?

I think I read back when I was unbricking that .KDZ files have to be converted to .tot, to use with this version of Flashtool.
Quick Question
Hey guys,
I am a bit of a rookie with rooting and i have an LG G3 for tmobile. I rooted my phone and had TWRP installed and accidentally attempted to install a software update and it soft bricked my phone. Here is my problem-all of the solutions i am finding for this issue require a PC, and I, unfortunately, am only running on mac software. I have no way to get lg flash on my mac and to make it comparable with my phone. Is there ANYONE who can help me? I am at my wits end and CANNOT believe I was so stupid as not to make a backup flash but I, as per usual, did not think about it at the time. If anyone could help me, I will be forever in your debt.

I believe you can run virtual Windows on a Mac, not sure if it works with Flashtool though.

Why so serious, use bootcamp and install windows 7 directly, and come into my debt.

Unable to boot my rooted LG G3 S (beat), stuck at lg logo.
hello everyone. I recently rooted my lg g3 s (beat) D722K. After a few weeks I was trying to install apps as system apps using ES file explorer for which I had to copy the desired apk in the system/apps directory and restart the phone. it worked for a few apps (which I successfully made sys. apps) but not for a majority of apps . Everything was fine until now . After that I wanted to normally install an apk but the phone was unable to install it showing ' application not installed' . Then I tried to install other apps but got the same result . I decided to reboot my phone but it got stuck on lg logo and won't boot .
I tried to factory reset it using hardware keys but after wiping all the phone data it again got stuck on the same sucking LG logo .
I also tried to update firmware by connecting it to windows(8.1) pc in download mode which didn't work either. The firmware download got stuck at 0% everytime I tried.
please help me in getting out of this issue . I will heartily appreciate any help regarding this issue.
thanks.. in advance.

[Q] Soft-bricked LG G3 D852

Hello,
I recently just got the unlocked LG G3, used to have an iphone so pretty new to the Android software itself. It froze while I was playing music so I did a hard reset and with that the firmware was updated to Lollipop. Calling, messaging, and music didn't work so I attempted to downgrade my LG G3 using Flashtool (Followed exact steps on here androidexplained/howtodowngradeLgG3, can't put URL because I'm a new user) and I used the Bell firmware (I'm sure the phone is originally from Bell because they had pre-installed apps). Everything went smoothly to the very end, however it got stuck on the screen where the LED light is flashing and the logo of LG continously shines (is this boot-loop?). I've tried using PC Suite to reset the software however it doesn't recognize my phone. Is there any suggestions you would recommend me?
Thank you for the help

Try to re-flash it again with the LG Flashtool and be sure to follow all steps correctly. It should work. Don't disconnect the phone until the process is finished. If the process freezes at 85% it's ok, it means the phone is rebooting and wait until you see a blue screen with a "3" on it. Then disconnect the phone and take out the phone's battery and put it in again. It should boot correctly. The first time to boot is always a bit longer. Just be patience.

[URGENT] Needs help restoring back my LG F400L

I don't know where to start. So I changed the resolution of my LG G3 F400L to 1080p via terminal. then I reboot it. The LG boot logo appear, after waiting for a while the logo won't go anywhere. the boot sound can be heard also when I touch the screen I can hear unlocking sound and touch feedback which means my device is working properly JUST the LG bootlogo covers up everything just like a curtain.
Another thing is, I tried to boot it to recovery to restore my firmware but it just won't work. My device has TWRP flashed by AutoRec. I used every button combination and tried like 100 times each that I found here: http://forum.xda-developers.com/lg-g3/help/f400l-recovery-t2960352 but the device won't boot to recovery. It just boots normally and stuck on LG bootlogo as I mentioned above.
Running to a dead end. I put my device to download mode (which the only mode that I'm able to do) to flash my device back to stock ROM using LG Flash Tool. After a few processes it stucks at S\W Upgrade part saying "Upgrade stopped due to an error". Just so you know I have the latest driver installed.
The stress and frustration really makes me want to bump my head to death. Any help and solution IS GREATLY APPRECIATED!
Please Help me.

LG G3 stopped working after installing recovery

Today I was trying to install a custom rom, but I messed it up and had to reset it to stock rom.
After that I reseted it back to stock rom, I rooted my phone with Kingroot and used this app: https://play.google.com/store/apps/details?id=b007.autorecd855 to install recovery. After that I powered off my phone and now it won't turn on. Already removed battery a plenty of times, when putting in the charger nothing happens, pc won't see it also.
The only moment when my phone lights up is when I remove my battery and put it in the charger, then it basically says that it's charging but with no battery in it. Also when removing the battery and connecting to my pc it only sees it as a unrecognizable device.
Suggestions on what I can do? IF not, poor me, gonna buy a new smartphone then.
Btw, I still have some garanty. Maybe it's worth sending it to the support services.

You used wrong autorec install LP recovery to MM. Download MM version autorec from LG G3 Xda forum. Try flash back to stock or something else. Instructions are in LG G3 Xda forum if you search more. Sorry.

Hmm, I was really sure that I used the right one.
Anyway, how can I flash it again if I can't even get the lg logo to show, neither get him in download mode or that my pc recognises him?
Btw, I still have some garanty. Maybe it's worth sending it to lg.
If you have no access to any recovery mode, Fastboot or download mode.then use the method of Qualcomm 9008.btw your warranty is void because you have rooted device and messed with it.

I also had same issue and I'm also sure that I used the correct Autorec version.
I sent the phone to LG because the warranty is still valid.
I know how to fix this

i remember after 1 day of having this phone this happened this was likely caused by having the latest boot loader i remember this because i fresh installed the marshmallow kdz after that i installed autorec mm it told me to restart and my phone died there, however after spending 8 hours straight i found a solution the smart boot diagnostics tool can write an older version of the boot loader understand that your phone must be in the qdloader9008 mode, if your PC doesn't detect the phone make sure you install the drivers in the zip from the download install the 32 bit if on 32 bit system or install 64 bit on 64 bit system. Hey if you need assistance on doing this Download team viewer and i'll be more than welcome to help unbrick our d855

Screwed my G Pad V700 up.

Can anyone help?
I got an LG G Pad 10.1 V700 a while back that originally was a tablet for a medical office and had a customized launcher that only had kind of like a brochure system on it.
I managed to do an upgrade using LG PC Suite and got the factory system back up and running. It was running great and recently I rooted my Coolpad Catalyst and decided to do the LG pad too. I used Kingoroot.
The Cataylst rooted fine but when I did it on the LG it said it was already rooted. I figure they must have rooted it to make it function like they wanted for the medical office.
Well yesterday I put the app My Spectrum (cable company) on it to see why I was having an internet outage and it complained about the rooting but worked anyway. I remember when I was trying to root my Android head unit in the car using Magisk I found that Magisk has many ways to hide the rooting from apps that don't want to work on a rooted device. So I tried to install Magisk on the tablet and it installed it and gave a button to reboot but when I did it's now stuck on the first LG static screen and on the top left it says "Error: boot certification verify".
I tried to do a hard factory reset using the buttons and click the button yes to do it but it keeps coming back to the static screen and the error.
Does anyone know how I can fix it?
I can't even seem to get my computer to recognize it no matter what LG drivers I use nor do I seem to be able to get the tablet into "download mode" that I've read about in searching for a fix.
All I can get it to do is go into the factory reset which doesn't fix it, some CS and S/N screen, the static LG logo with the Error: boot certification verify on the top left and a non-animated charge screen.
I can't even seem to get the unit to stay off.
Have I hard bricked this damn thing? Is there no way for me to fix it?
