I have an lg g4 h811, when I tried to flash a cm14.1 rom it said it was a h815 so it didn't work so I decided to get stock rom (cause I bought it from eBay and the previous owner installed a random custom os with bugs). So I tried to flash a flashable lg g4 stock h811 rom in twrp and after the flash, I pressed reboot and it turned off and won't turn back on. It won't accept charge, it wasnt recognized by my laptop, and won't turn on. Any help would be appreciated thx.
:good:
Can you get back into TWRP recovery mode? If not, can you get into download mode? Follow these instructions EXACTLY, http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
If that doesn't work, install LG Bridge and get into download mode and see if you can update that way.

more info is better than none, what did you do to "accidentally brick" your phone? and if you are stuck in download mode you could try the lg mobile support tool and re load the rom for your device.

READ completely, including the link in 4 before starting!!!
download the tool using the lg d851, under t-mobile. the tool is generic, and can be found at lg.com under support/downloads
1. install LG Mobile Support Tool
2. run Tool, it will query lg for updates and do so if needed.
3. Install USB Driver (dismiss if you have done so already)
4. follow this process: http://forum.xda-developers.com/showpost.php?p=51268802&postcount=21 (use 5. below to put into download mode, not vol up and down like the link states)
5. with your device off, hold the volume up button while plugging in your USB cable with the Tool open.
6 you system will recognize the device and configure drivers, this will take a minute.
7. continue following the link in 4.
I ran into the same problem and now i'm stuck in downloadmode!
Does this method work? Or is there any other fix yet?
Thanks in advance!

hey guys, don't ask for a different fix if you don't bother to explain how your phone got stuck in download mode. as for does this work? Why don't you try, it's the same tool used to upgrade firmwares instead of using OTA, and the link included shows how to get the tool to download the file (if it sees the same/current f/w it does not download the firmware) and you have nothing to loose, and this method is often used to recover from "soft bricking" your phone.
i was restoring my LG G3 to stock through the lg flash tool .....when i got through with it and restore was succesfull. somehow i forget the usb cable plugged through my pc usb port ...then connected my lg g4 that is where the flash tool got my Lg g4 on Downloade mode ....i tried all the methodes somehow i think the recovery is messed up .....i can get to the recovery through the button but it reboot straight to the download mode ....thanks every one for their support

don't think it's out yet, however my statement was somewhat incoherent. I meant to say if he had the kdz, he could use the flash tool to recover his phone.

Yea, at this point there no way to fix this without a kdz that I know of.
Call LG and tell them you need the kdz to restore your G4.
i was lucky, i had flashed twrp before my phone soft brick..

I got an LG G4 which is stuck on lg screen. When I put it in download mode, it shows download mode for a few seconds and restarts. I was trying to flash ZVB over ZVD and it ended up like this. Model is ls991 . Any help would be really appreciated!
Anyone got any idea? The whole thing started with getting rid of the Genisys rom ... I did not like it ... I thought I was going to bring it back to the stock, but then LG Up wrote an unkown device ... I thought it was flash with lg bridge ... that's what I lost. .. has removed recovery and has stopped updating at 16% ... since then it is only download mode I tried to update but failed with all three programs ... LG up to start - unkown device, LG bridge stop at 16% , LG Falsh Tool 9% ... sorry for my english
After modifying build files failed, G4 bootlooped at starting logo.
Tried to repair it with lg bridge, and it was forced to update to 6.0 v20c.
Flashed it with v10fkdz(5.1), and the error message was shown:"Error Code=0x2000, Can't decide current device mode."
Can anybody help me to solve the problem?
I think you broke your download mode; sadly, it is the only mode that you can flash via LG Bridge and LG UP. If you have an unlocked bootloader, you can flash an image through fastboot. As for me, I can't flash on either of those programs since I also broke my download mode and I have a locked bootloader. Otherwise stated, I have a hard bricked device. Waiting for some possible new program to fix my device
I tried on 3 different PCs, and another available G4 device.
The problem is still there.
I don't know why,
but after reinstall LGUP, downgrade of my phone is OK.
Thx guys
Hello. My LG G3 D855 originally ran CyanogenMod13 Nightly, and for some reason 6.0 Marshmallow GApps did not work. So I attempted to flash back to stock using LG Flash Tool. However after the flashing (successful), my phone would only boot into Download Mode, even after hard factory reset. Nothing worked, ADB, fastboot, nothing. So I then downloaded the older version of Flash Tool (2014), and the G3 D855 6.0 marshmallow KDZ. I believe this was successful, as now the phone changed from download mode to the MiniOS boot animation. However that is all it did, just displayed the animation. I attempted a hard factory reset (and the design of the screen had changed, which is why I assumed the KDZ flashing worked). That didn't help, and so I booted back into Download Mode, and tried flashing the TOT file for my device using the newer Flash Tool. However the new Flash Tool didn't even recognize my device, and so I, in one last hopeful effort, downloaded LG PC Suite to try and fix my phone, but in Download Mode or otherwise, my phone wasn't detected. I've tried flashing other versions of the KDZ on my phone, all unsuccessful. And of course there is no recovery I can access. Please any help would be extremely appreciated.
Hi all,
I was wondering, once I have custom firmware and recovery on my lg g4, will I be able to reinstall the software from LG Bridge. I understand that I could use the kdz downloaded by it in LG UP, but I was wondering, if I put my phone in download mode, could the update error recovery utility in LG Bridge also reinstall it?
Thanks in advance for your help

I tried this recently just to see what it does, but it even didn't recognize the phone. So you probably need to use LGUP (which I used to go back to stock on my G4) or TWRP to flash something else.

I just tried it and interestingly if the phone is in download mode, it does get recognized as an LG device and will initiate an Update Error Recovery
Hey guys
First, a little bit of history:
I own a G6 now, so I wanted to have some fun with my G3.
I rooted it (LGOneClickRoot), installed TWRP, installed LineageOS 14.1 and everything went pretty well.
The problem was that LineageOS 14.1 is terrible, huge lags, tons of bugs, so I tried installing another ROM through TWRP, I don't know what I messed up but I messed up and the flash failed. I dont remember exactly what I tried to flash after that but I failed again and then classic --> Stucked on LG boot logo, no recovery mode, no download mode, nothing.
So I used the popular fix for hardbricked G3, creating a short between test point and ground while connecting it to revive him, and it worked. I went with the whole procedure in BoardDialg and stuff. Kinda surprised by myself that I didnt go full-panic mode creating tons of threads everywhere lol, I managed to make it work even if it took me something like half a day of learning and work.
Now I'm back to stock Android 4.4.2, rooted with LGOneClickRoot again and everything is fine.
I mean... Almost everything is fine, because now I want to be able to install Magisk, and I found that Magisk is for Android 5+.
So there are some informations I need to gather before going further and risk a brick again (please no more short on the motherboard lol):
1- Can I flash a stock Lollipop ROM with LG Flash Tool in download mode using CSE Flash ? Is it a proper way to do it or do I really need to go through this boring TWRP recovery flashing again ?
2- where can I find such a ROM (stock Lollipop for d855) ? And which version to chose ? v20a, v20e, v20f, v20h, v20i, v20p, v20t, v20u, v20w or v21a ? I've been looking for hours now, hard to find reliable informations about all different versions.
Thanks for the read, I hope someone can help me
UPDATE:
I flashed a Lollipop v20f with LG Flash Tool and it's working fine.
I heard that after v20f, newer versions were "harder" to root so I sticked with v20f.
I'm gonna play around with Magisk now and see how it goes.
I'm in the same boat. I also went back to 4.4.2 via TOT. The I rooted and installed TWRP. how I want to restorel my RR 5.8.5 from a TWRP backup. My question is to I have to install the 35B bootstack before or after the restore or at all?
Hi,
Upgrade (LGFlashtool + CSE flash) to V30B
Follow this post ==>
https://forum.xda-developers.com/lg-g3/general/root-twrp-marshmallow-d855-30b-t3286268
Then you can install custom Rom ou upgrade to stock V30N (with root : there is a post about it)
Hey how did you do the unbrick process? I stuck at flashing kdz eventhough i have correct dll and drivers installed
hi,
Try LGUP instead of LGFlashtool (download mode and type *.kdz + select kdz file in LGUP)
Depends if you're hardbricked or softbricked. I was hardbricked so I had to create a bridge between 2 points on the motherboard and reflash everything one by one. I formated recently and didnt keep all these things but I can get into it again to try to help you.
EDIT: LGFlashTool isn't enough if you're hardbricked, you'll have to use other tools and open your phone. First step is identify if you're softbricked or hardbricked, google it you'll find your answer
Mine was hardbricked. I use shorting test point method and successfully flashing partition. Then I flash kdz using LG flash tool 2014, my phone stuck on boot logo. Then I do factory reset. Still same. Last option, I use LG UP. It stuck on LAF info with number on it. Is my LAF file damaged?
Hi,
With Boarddiag try this :
1-EMMC TEST Option "erase" ;
2- then Restore theses partitions and reboot in download mode and flash Kdz.
1)Boot
2)Aboot
3)BackupGpt
4)Boot
5)dbi
6)laf
7)PrimaryGpt
8)Recovery
9)rpm
10)tz
11)sbl1
