D855 - Flashed wrong baseband... red and blue flashing LEDs - G3 Q&A, Help & Troubleshooting

Hey guys,
so I recently decided to update my LG G3 (D855 EU) from CM12.1 to CM13, but it just told me that I have the wrong baseband.
So I flashed a baseband someone recommended on reddit/here (xdabbeb_vs98535b_bootstack.zip) which apparently wasn't the right one.
So I just rebooted (bad idea), now my phones LEDs are just flashing red and blue right after the LG logo.
I tried the KDZ and the TOT method, but both of them failed because they can't seem to find the device!
LGUP just shows "Device Unknown". LG FlashTool never goes past READY!! And LG FlashTool 2014 cannot connect to the device.
I installed every driver I could find. (LG United Mobile Driver, LG Mobile Support tool and even LG PC Suite)
I tried uninstalling the device a couple of times, but every time it just can't seem to find any drivers for them automatically.
So installed them manually. I have "LG Electronics Inc." and "LG Electronics, Inc.". Only the first one worked, the second only gave me an Error 10 in Device-Manager (Device cannot be started)
The device is already configured as COM41. I also tried COM 4 and COM 5 for the flash tool 2014 and LGUP.
I tried everything on multiple computers and I even set up a VM to try it on Win7!
Please help me! I don't care about my data, I just want my phone back
My warranty expired a couple of months ago...

I'm using Windows 10, but I also tried it on Windows 7.
Because Windows 7 seems to work better with the tools

Google LG G3 drivers. I had the same problem with my G3 and i got drivers for the G3 only,installed them and was then able to use LG Flash atool 2014.
Thing is if using Win 10 you need to disable Driver Certification or 10 will not recognize the phone for upgrading etc. Also once disabled they will need to be done each time you start up from cold as Win 10 does not retain the setting when switched off.

I tried that already, but it can never find any drivers... I disabled Driver Certification but nothing changed.

Just a quick question... Are the Drivers supposed to be by "LG Electronics Inc." or "LG Electronics, Inc." because it is showing both of them and I really don't know which one to choose.
(I can see both of them if I manually select a driver)

hi all!
i have the same problem and didnt even got to the PC part.. my phone (lg g3 d855) just flashes red and blue lights.
if you can please explain to me (step by step) what i should do to make it work again..
i installed lolipop cm12 (had stock kitkat by LG before) on it and it worked fine but the whole purpose was to get the MM cm13 so thats when i flashed 35b instead of 21c as requested.
please help me, thank you all.

[Q] lg mobile support tool

HI , first post , so here goes....have an old optimus g which i tried putting recovery on it....when phone rebooted , it had the secure booting error on it ....i went to the xda unbricking guide and have been stopped by the fact that the lg mobile support tool does not see my phone , and after i have downloaded and installed the drivers for my phone the lg optimus e973 .....
Verify that your phone is recognized and connected by checking the LG Mobile Support Tool. The text "Waiting for connection...." should be replaced by your model version LGE975 LGE970 or similar
..........i think i put the right drivers because i looked for them under the driver options for my phone ...but it still will not recognize my phone ...thanks for the help ...if any....have a great day.:cyclops:

Have you choosen ART modality?
If i would say "what the hell is that" ... would u slap me?
No.. i dont have chosen that..
Bigger problem is that i dont get any usb driver working for firmware update in Download mode.. =(
OK... i managed to get the drivers working.
But further Problem ist now that im not able to flash anything on my device...
Neither the TOT Method, nor updating with the Original LG Support Tool is working...
Support Tool tells me my Model Number and that my Version is most actual.
If i update anyway it stucks at 4% and tell me it cant connect.
TOT Tool tells me that my Version Number is not correct... but it is..
With the KDZ Update Tool it stucks at 4% like the Original method.
Same problem here
Any one can help us?
Solution
Hi there,
the Problem was my PC...
I was on a Windows 8.1 64bit.
Switched to a Win7-PC and all is working fine.
You should try to use the Original LG cable, or another "Original" Cable and connect it to a USB-Port on the Back of your PC (directly to the Mainboard)
On a blank Win 7:
- I installed the LG PC Suite
- Updated the PC Suite
- Connected my LG in Download Mode
- Let the PC install all drivers,
- Disconnected the Phone
- Downloaded the actual LG Mobile Support Tool
- Let the Support tool do the work
After this i got my first OTA Update and its working like a charme

Hard Bricked D850PR

So the story goes as this:
ATT G3 accidentally flashed a D851 rom... phone rebooted now its a hard brick
I have tried every method to restore it to stock (lg flashtool 2014 and old flash tool method, tried enter TWRP nothing happened)
My phone is detected as it were in Download mode, but it doesnt let me flash anything.
I downloaded the "generic" LGUP8794.dll and tried to flash stock D850 and stock D851, jeez I even tried to flash LS990 stock rom... same error every time.
Downloaded stock D850PR20A_01.kdz and tried to flash it through Flashtool 2014 and just getting error...
I'm really out of options now.
I dont have warranty so its out of question the "return my phone" thing.
Thanks in advance for any reply or suggestion.
PD: I get no "QHUSB" or "fastboot" mode either.
Try using a different usb port. LG flash tool hates USB 3.0 so use USB 2.0

I have tried with 3 different computers, one with XP, Win7 and win8.1
I never use USB3.0 unless its with a memory stick
Can you go into download mode??
Sent from my SM-N910F using XDA Free mobile app
No, No Download mode, but my phone is connected as it were in download mode.
My screen is good, I know cuz when i connect the usb without battery it lights up and shows an image of "missing batt"
No TWRP either
Any update on this? I just rooted my D850PR and then used AutoREC to install TWRP, then I turned it off to reboot but it never booted...it also lights up the display when connecting the USB cable without the battery but that's all it does

i cant believe there is no clear solution for the LG G3 brick.
There is a solution
I have faced this issue with my LS990. accidentally flashed D855 ROM then bricked. THere is a unbricking method which is very hard and you have to do it with patience.
Try this
http://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091
You might want to short 2 pins of G3 motherboard. message me if this method didn't work.
Good luck matehttp://forum.xda-developers.com/lg-g3/general/unbrick-lg-g3-qhsusbbulk-qualcomm-9008-t3072091
I had that problem, flashed d855 rom on a d850pr, and it went into bootloop, but I just went into recovery, flashed a D850 rom and everything worked fine. I did have your problem once, but with a LG Optimus L2, I tried on windows 8 and 7 but the LGflashtool always stop with errors, until I tried on XP, i could restore it. (sorry for the english)

LG G4 not working with LG Bridge

Hello all. Not been on XDA for a while; but I hope you can help me. I have an LG G4, which I just received yesterday from Vodafone UK. I tried to connect it to LG Bridge today to check for updates, but the Bridge would not work with the phone. The phone name showed up in the bottom left corner of the Bridge screen. It said something about it cannot work with this phone at this time; please try later. I had installed the drivers for the phone, and switched debugging on and off a on again. I tried it with usb set to all the different options; but nothing worked. Have you got any ideas as to how to get this working correctly?
what drivers did you install?
The official WHQL_Ver_4.0.4 from the LG site? (can't link it)
Worked with LG Bridge for me on my stock H815.

I had LG Bridge switched on, and I had the LG drivers from the website. I think the LG Bridge is incompatible with Windows 10, which is what my laptop runs on. However, I did manage to get both my husband's phone, and mine, updated to Marshmallow. I used a program from here on XDA called LGUP, and found the relevant kdz file to run the LGUP program. The phones are both on stock Marshmallow now, with no sign of the Vodafone boot menu. I ran LGUP as an update, so that I was able to keep all my apps, files, etc, as they were before.
Thank you for your help, @Yuuseki, I appreciate it.

Bricked!!! Help me out please!

I'm a newbie and don't know much about phones. I rooted my phone for the very first time and was about to install CWM.
I've an LG Optimus G Pro F 240K.
I downloaded an app namely Flash Optimus G in .apk form and installed it on my phone. I tapped on Flash and the screen read "SUCCESS! Now re-boot you phone into recovery." I tapped Reboot into recovery. That time and now, i'm numbed. The phone isn't responding at all. I'm using Windows 10 Pro. In device manager, an exclaimed mark icon gets visible when i connect my phone.
The device name is QHSUSB_DLOAD.
I've downloaded official stock firmware 4.4.2 kitkat. When i use LG Flash Tool, it says your device isn't connected to your computer.
What should i do???

Or downgrade to Windows 8.1 and then restore by KDZ
qhsusb_dload means you´re in qualcomm mode, and also means that you´ve killed phone boot. from what I know, only medusa and riff boxes can fix it.
