G3 D855 - System ok - Stuck in TWRP logo - Stuck in Download Mode - G3 Q&A, Help & Troubleshooting

Guys I have serious problems with my LG G3 D855 - From Brazil
A long time ago I can't enter download mode because the phone can't pass the download mode logo (?), just like 'd.jpg'.
That wasn't a problem till the same occours in the recovery, just like 't.png'. No matter how much time, the phone keeps stuck in this screen.
My system is CM 13, I can't install any update or kdz or tot file. The system boots ok, the problem is that CM 13 is nightly and some apps doesn't work properly. I've tryed flash original recovery, the new twrp 3.0, the old twrp 2.8.5, and still get this. Tryed clear cache from adb but no sucess.
ADB through system still work fine, that can be a path to my solution.
Anyone can give a hand?
Anyway, Thanks!

Download mode might be about driver
Twrp did you install right version
Reccommend reinstall whole system kdz or tot flash

Can you show me the correct driver? I've already installed two drivers for this phone and the Google adb drivers

New version of FreeGee used; stuck in CWM bootloop

I have done this before but I used what seems to be a different version of freegee (didn't have the option to backup efs or flash TWRP) so I unlocked my device and after it had completed I rebooted and then powered down. I put my phone in to CWM and flashed the stock debloated ROM. After flashing this ROM I was stuck in a bootloop. I ended up using LG Tool to get it back to stock. I thought it must have been a random once off issue so I tried again with Freegee, same thing happened, only this time no matter what I do I can not get LG Tool to fix the issue as it keeps giving me the error of low battery even though it is at full capacity. I then tried to use BC2 to flash a kdz file and I get the same error. I have since tried factory resetting, sideloading different recoveries, ROMs and basebands without boot. I have tried to use LG Tool about 50 times and it is not working. I have changed USB ports, reinstalled drivers etc, just keeps giving me that error. Yes I have set permission in the app and I am using Windows 7

Thank you, I will use that if I ever get LG Tool to stop throwing me the low battery warning. What a stupid program to not give you the option to bypass it. Surely there is a way I can do this. My battery is at 99%. I just flashing madmack hacked and lockified recovery and now I can't even get in to recovery to do sideloads. I am running out of options, my only way is to get LG Tool or B2C to work
EDIT* I have recovery back. GRR why is this stupid message about low battery keep popping up

have not tested this from cm rom but works from any stock. bytheway i have optimus G not pro
from recovery adb push rom.zip (your rom)
adb push rom.zip /sdcard/0
(0 required for cwm and cm10.2)
flash that rom
enable debugging
run lgflash tool one that supports large files or the online one it will pass the battery and auto restart in download mode there it will give error just unplug replug and retry and it will be flashed this time.

To anybody that faces the same issue:
in recovery sideload install madmacks TWRP file attached below
after that is installed flash CM11 using the same sideload
The command in adb is adb sideload (your file name in here without the brackets.zip) You must include .zip
It is strange because it didn't work the first 3 times I flashed the ROM and on the fourth it worked, so keep trying
i can fix bootloop to cwm or recovery just 2 minutes. but u have to backup your stock recovery fírst before install cwm or twrp.
so thiss step to solve after u have boot loop. that u need to restore back your stock recovery on mmcblk0p28 then reboot. you will stuck at factory software repair. keep ur fone connected with the computer and type adb reboot. then u can boot into android os. and final step. u reinstall your custom recovery again and Enjoy. this fixing not for newbie and im typing it on my fone. someone can make automation script to help People solve it im lazy

Thanks for trying to help. I am not running stock and can not get a stock ROM to work (with locked bootloader obviously)
LG Tool is requesting for a TOT file which the E988 doesn't have, I have tried using E98810D_00.kdz file in the software field but it is not recognising the cab file. The DLL file is recognised but I don't know what else to do from there.
LG Mobile Support Tool keeps failing on me due to low battery error which as you can see, I have been trying my hardest to get it to work. Battery is at 99% but it still won't flash! - I am stuch with a custom ROM and a dodgy unlocked bootloader due to the latest release FreeGee.
I tried the old file you attached but it fails to download the image file to unlock my bootloaders, I guess because it is already unlocked.
What I need now is to find a way to relock my bootloader that doesn't involve LG Tool/LG Mobile Tool and then try the old FreeGee app again. Or I find a way to get passed this stupid battery warning

First try to use LG Mobile Tool. All files and instructions found here CLICK ME
If that doesn't work the follow the instructions I posted earlier and it will get your phone booting again. As for getting back to stock and unlocking the bootloaders without causing kernel issues, I am still waiting for a response from Seth. He has been making a lot of changing as this is a known problem. The latest version is supposed to work like it used to now.

Thanks! This worked 100%. Something's really up with the freegee CWM, totally useless. Had 3 days of a headache till I saw this post. I used to be a CWM guy, now TWRP all the way...! The interface is touch based and much easier to handle than CWM. Best of all it doesn't go into a bootloop! Cheers! :good::good:

Probably you are not going to like what I have to suggest because it's a little longer process. My suggestion would be to download the LG Support Tool from http://www.mylgphones.com/lg-software-tools-download
Download LG drivers as well from the same link. Connect your phone to PC. Let the support tool download and install the stock firmware. Then root the device and install twrp recovery. Then proceed with wiping and installing 20A. Yes, it's a longer way but the proper way in your situation. It should not take you more than 30 minutes to be back in the business. Good Luck!
Didn t work
tnx but i allready try it,i try lg flash tool lg flashtool 2014,problem is i cannot go to download mode and the computer dont recognize pc.Only if i go to lolipop 5 but there is no buttons,notifications and i cant to nothing,cant copy to telephone.Becouse the files are missing who i delete it accidentally
I can go to recovery twrp 2.8.0.0 and flash from there.
Adb mode
So i can acces to adb mode from computer.Is there any way to install stock firmware true adb mode or i have to go to download mode?

Don't know about stock firmware but you will be able to download a custom rom and then adb sideload it from recovery. Least you will have your phone up and running while you sort the rest out.

Flashtool is different than support tool... But in your situation it probably wouldnt work anyway.. So are you stuck in fastboot? If so youll need to flash the boot.img and laf.img for your device. If you can get into recovery just flash a compatible rom. You might need to still flash a boot.img first though if it was erased. I don't think a lot of roms have a boot.img included unless it's bumped not sure about that, I have d851.

To restore download mode you need to flash the laf.img. So what I would do is type fastboot erase laf. Then with the new laf.img file you got from your link placed in the proper location, type fastboot flash laf laf.img. Once download mode is back you can kdz flash and return to stock. You might follow the same procedure with the boot.img just be safe but this should be all you need to get back to stock.

What do you think about the screen is it software issue ?Maybe something is mixing together some files maybe...
I did the same thing.....
I took my sd card out and placed aospa rom on it and then flashed it in twrp...then when i have access to the phone again i reinstalled my favoured (cloudy) rom...For some reason i couldnt flash any rom via SD other that the AOSPA one

Does it say success? You might need to change directory in fastboot commands. If you type adb devices does it pop up information about your phone? If you can still get into twrp do like above. I think cloudy restores the entire system on to your phone. I could be wrong I don't use custom roms. I flashed it once for the hell of it and I think I remember it formatting the system and rewriting it.,.

VK810 Download Mode Boot Loop =(

Here's the situation.
-gpad on official verizon kitkat. rooted with TWRP installed.
-tried doing the OTA update
-upon reboot for OTA update, boot loops to twrp
-flashed stock recovery.img from TWRP terminal
-boot loop fixed and able to boot into original OS before OTA update attempt
-tried OTA update with stock recovery but fails @ 5% with error code ERR:0x13E
-used the LG Mobile Support tool to try and manually update
-goes into download mode
-update fails
-now only reboots to Download Mode
-tried all button combinations to get into any other mode. fails.
-even tried taking apart and pulling battery
Result: still stuck in download mode.
Any suggestions guys?
Just in case someone else is having this issue, I'm not deleting this post.
looks like I got it fixed.
I ran lg mobile support tool on a diff computer and this time it went through.
All up and running again.
I got myself in this same bootloop. Mind sending me the recovery.img file or showing me the way to the correct LG Mobile Support Tool?

1. Boot into TWRP
2. Go to Advanced, then Terminal Command
3. Browse to Folder: /dev/block/platform/mdm_sdcc.1/by-name
4. Hit Select button
5. Now in the text field type "dd if=/dev/zero of=./fota" without quotes and Hit "Go"
6. Reboot system
You are a life saver! Thanks.
Thanks a lot from me as well, got me out of the boot loop I created by trying to update using an OTA on my rooted LG G Pad and these commands got me back up and running..
Just ran it now thank you Sir! ?

Hi! What variant of the G Pad 8.3 do you have? I would use LG Flash Tool 2014 instead of the official tool, and download the latest official KDZ file to use with it, made for your variant.
You'll have to download the drivers for your variant from LG's website, reboot the PC, then plug the tablet into the PC while it's in Download mode. Can take 1 to 10 minutes to load the driver. Then use the flash tool I mentioned.

Lg g3 700 fastboot mode started when going to recovery

Hello I hope someone could help me.
I have an lg g3 D855 international version, with kit kat 4.4.2 and its the 10e version.
I've root my device in order to install new custom rooms. At first I wanted to go to android marshmallow official and wanted to do the flashing with lg flash tool, but in every computer I have, it does not working, its either stuck in 2% and then it fails, or 4% and then it fails, and I tried to erase an install the new drivers and the old ones in the computer... But I couldn't get it to work. So I decided to root my device, and install twrp recovery, so I did. First I try to install the latest version of twrp, this I did it directly from the phone via TWRP manager. It was supose to work... But when I finish installing and went to recovery.. It went to a black screen saying "[700] fastboot mode started" or sometimes "[760] fastboot mode started" to my surprise the phone is not softbrick. I removed the battery and then reboot the phone and it works... But everytime I go to recovery or tried to install a new bump recovery... Because i thought that was the problem is still the same. I tried to install a new recovery with ADB but when I put the file path in order to install it... It said it couldn't find the recovery img in the path... But it was there... And I tried, but couldn't get it to work. I have some experience with custom roms on samsung galaxy s3, but change my phone, and this lg g3 is really making me crazy.
Thank you very much in advanced.
Any updates? Im having the same exact problem (d851)
In which computer you are trying the process. Which windows is installed on computer that you are using for installing stock rom.
Which guide you are following to install stock rom. Have you unlocked your device for bump, if not follow the guide.
http://forum.xda-developers.com/lg-g3/orig-development/bump-unlock-lg-g3-twrp-d852-d852g-f400-t2900614
I am dead sure that your board is not d855.open your phone to confirm this.that is the reason your twrp is not compatible with your board.

Same problem for me.
I was using TWRP for weekly update of LineageOS 16.1 on D855 with no problem.
Before updating to Lineage17, I updated it to twrp-3.4.0-0-d855.img (https://eu.dl.twrp.me/d855/) using TWRP App.
Then I tried to boot in Recovery mode and I got black screen with the message:
[700] fastboot mode started
I tried older version with no success installing them with ADB or TWRP App.

Help me bring back to life my phone

Hello,
So, i was trying to install root on my LG G4, version H815 (no letters/numbers after)
I did successfully unlocked my bootloader (info message on left top corner when booting) - official LG unlock
Booted into TWRP - twrp-3.0.2-0-h815 from ADB
- Installed UPDATE-SuperSU-v2.46.zip (which is located on internal storage) from TWRP - https://download.chainfire.eu/696/SuperSU/UPDATE-SuperSU-v2.46.zip
- Clear cache (dalvik)
- Reboot
Phone started booting, and got stuck on the LG logo
I did try to get it recognized in download mode and I did try to enter recovery mode (but I didn't install TWRP, only boot into it.. so I was left with the "default" one)
My phone doesn't enter recovery mode (I get the dead android bot with red exclamation mark)
At this step, somehow ADB recognized my phone, and I tried installing SuperSU again, and once again same thing happened.. I got stuck on LG logo
After this until now, I'm not able to:
- see my phone in ADB
- download mode with LGFlashTool2014.exe to flash .kdz "Europe OPEN H81510D.kdz" - getting error on LG Mobile Support Tool - "Upgrade stopped due to an error'"
I was following this: http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
Currently I'm trying all the steps from here http://forum.xda-developers.com/g4/help/lg-g4-stuck-bootloop-t3268734
I just wanted to ask, is there a better way? Is there a working way?
Thanks, any help appreciated!
What firmware were you on? LP or MM. If the firmware was MM then you should have used SU 2.52 otherwise you end up as you are now.

You should also have flashed any custom kernel first that will allow you to not boot but install TWRP and then easily root. To flash firmware for G4 we use LG UP, nor Flashtool2014 and Mobile Support Tool ( G4 is not even compatible with it! It says on their website that you have to download LG Bridge)
I fixed it by using LG Bridge
- Update error recovery option
It installed android 6.0 on it
Then I used BETA-SuperSU-v2.67-20160121175247.zip for root, and everything seems to be fine
Thanks for your help!
