LG Bridge for software reinstall - G4 Q&A, Help & Troubleshooting

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

[Q] Can't change into download mode LG G3 D855

Hey Guys,
I want to flash the stock rom on my LG G3 D855, but somehow lgflashtool cant change into download mode. I tried to flash with the .kdz file but it doesnt work either.
And now my phone is stuck in the firmwarte update screen. I cant do anything when I try to turn it on it just goes back into the firmware update screen. I tried to do the hardreset with the buttons but it doesnt work.
Can someone please help ?
EDIT: Hey guys I solved the problem by returning it to telekom (my carrieer) and they send me a new LG G3 on the next day. But when I tried to flash my G3 with the .kdz method I didnt put the .kdz file into the same folder as the LGFlashTool, maybe that was the reason why it didnt work.

What method did you use?
If you used the .kzd method (http://forum.xda-developers.com/showthread.php?t=2785089) dont forget to put the .kdz file in the same folder as the LGFlashTool
If that doesnt work, you should go and replace it.

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.

no i did not fix mine yet i am on tmobile am not sure if they will consider return am still within retun policy
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..
Sent from my unlocked and rooted LG-H815
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

D855 MM Stuck at TWRP after flashing KDZ with LGUP

I dont understand why this happens because i follow the rules exactly.
I was using MM with TWRP+Root.(Not kingroot or other, just SuperSu 2.52) I was flashed .zip file from Xda. I mean i was using L and after that .zip files pops out for MM, i just simply flash the MM zip file and got it worked.
After flashing kdz file with LGUP now my phone stuck at twrp. Now i stuck at twrp. I tried to restore my backup on external_sd but didn't work either. Any ideas?
LG Up can't wipe twrp , so tried flashing again with LG Flashtool with lastest driver.

I had same problem with it being stuck at 60% what I did was not to press cancel or unplug but pressed retry and it worked. Also change the language to English and the question marks will disappear.
As for the device disconnected issue i'm not sure how to solve that one you could try running flashtool in windows 7 compatible mode.

Bootloop after lg bridge

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

these devices have locked bootloaders. how did u install twrp?
best bet would to be to find what ever firmware device was on and reflash it with lg up or flash tool if u still have download mode.
Thanks for your reply.
I really don't know what i did to install twrp.
I try to use flash tool but doesn't detect my phone.

With flash tool goto device manager on pc.
click ports and com get into settings on it and change com port to 41
and have device in download mode powered off volume up + insert usb cord from pc
@imider I have the same problem trying to recover from a hardbrick on H815. Tell me what happens if you pull battery, plug bag, hold VOL DOWN and insert USB. Do you get fastboot?
EDIT: You might be able to flash it in FlashTool (I said no before) because I see you have Official Status not MODIFIED.
Thanks for your reply guys.
I manage to flash it with LGUP with a TOT that I downloaded.
Thanks.

Congrat @imider ,
maybe you can share what you did to fix your G4
Hello,
First I wanted to flash a clean rom on LG G4 H810 and I don't know what I did but the flash doesn't work and my phone has a black screen even the logo is not displayed.
When I connect my phone to my PC (windows 10) it's detected as "Qualcomm HS-USB QDLoader 9008".
Now this is the step that I follow to repair my phone :
1) I follow this tuto : https://forum.xda-developers.com/g4/help/lg-g4-bricked-qualcomm-hs-usb-qdloader-t3609999
2) After that I can enter download mode
3) I flashed a tot with LGUP
I hope it will help.
