Hello!
I have one LG G3 D815 16GB wich is stuck on fastboot mode, all I can do on it is to enter the Hard Reset menu, but even if I choose Yes from that menu, nothing happens.
When I try to put it in Download Mode it does nothing, but after few moments after the phone is connected to PC on screen appears "[211630] Fastboot mode started".
Can anyone help me? The phone has get bricked from nothing, I didn't do anything to him to get it bricked.
If I try to power it on normally it remains stucked with LG logo on the screen.
Can anybody help me? With a tutorial or something?
Thx!
PS: I didn't installed any custom firmware or something like this on this phone. I attached down there a photo with the screen wich appears after I connect it to PC.

No one can help me?
Do you have warranty?
I believe jtag is only option here as you cant enter anywhere.
Happened to me today, this one worked! http://forum.xda-developers.com/showpost.php?p=57655028&postcount=15
Hi guys, so my problem is I was installing a new rom on my rooted D855. everything was going along fine but then the process stalled. I left it running for 15 - 20 minutes but it was still on 33%. I tried holding the power button in desperation which shut the thing down. Now when I try to factory reset it goes to the prompt screen, I answer yes, then it asks me to confirm. from there however it goes to LG splash screen and eventually a black screen with Fastboot mode started. -reset- portcharge -reset- portcharge fastboot: processing commands in the top left corner. That's it.. If I try download mode it goes to the download screen and then to the black screen as described above.
Sounds pretty ordinary but if there is an answer out there I am sure one of you guys will know it.
TIA
i had some similar other issue and the only way i got out of it, is by using the lg flashtool 2014 and the KDZ file appropriate to your version
there is a thread with a step by step instructions.
you launch the flashtool, then insert the kdz file (original stock rom) then you put your phone into download mode (making sure in windows/controlpanel/devicemanager/ports - comp port 41 for the device driver)
you press volume up and plug it into the pc, the pc sees the phone and it starts reflashing the custom rom to your cell.
i presume that as soon as your download mode is working by flashing whatever command is corrupt and makes your phone black should be bypassed by then
i hope it helps - look for the thread how to flash the lg
Thanks I'll give it a shot. Not sure device manager is seeing it properly. I'll have a play and see. Thanks again for the reply
O.K here's the thing, my phone is seen in device manager as a Samsung Android Phone. Under the details tab it shows it connected via USB Modem Phone ADB Port. There is no option to change the port to 41. Anybody who can help I would be very grateful......
Hey everyone,
We have an LG G3 D855 here which has been interrupted midway through flashing a KDZ file,
Powering on the device gives us,
"Cause : Boot certification verify (secure booting error)"
Followed by the screen going off and the blue red LED flashing endlessly.
Download mode does not work,
Recovery mode does not work,
However, the factory reset screen appears, but when selecting yes it reverts to the LG logo and reboots.
Here is a screen shot of what appears in device manager on my PC after I attempt to enter download mode.
As you can see, it is "QHSUSB_BULK" in device manager.
We have tried adapting this guide for the G2 with Ubuntu, but the device is not recognized by Ubuntu. http://forum.xda-developers.com/showthread.php?t=2582142
If we can get into fastboot somehow we will be fine, but nothing seems to be responding. Any advice would be fantastic.
We also have another idea, of super hard bricking the device somehow so that we can follow this tested method of getting out of the brick,
http://forum.xda-developers.com/lg-g3/general/fix-unbrick-lg-g3-stuck-qualcomm-hs-usb-t2933853 not sure how to get either of these though so some help would be great.

Thanks mate, are there no software alternatives to this problem? We have been looking literally for hours.
It works! I have found a diffrent package at web. The "Device is not in DL mode" issue is much better with! If the DL breaks, reject the USB-cable and klick start again the process should start without probs. For prevent the app to freeze exclude cust.mbn, system.mbn, userdata.mbn, cache.mbn every .mbn bigger then 50mb. This files we can flash later with Flashtool after the device is back to life

XDA user roopesh had the same problem: http://forum.xda-developers.com//g4/development/stock-h815-20a-stock-rom-t3233049/post63721579
He/she fixed their problem by following this guide: http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848
Or follow my guide:
i) Make sure you have the LG Drivers installed from here: http://oceanhost.eu/e4h2px4e0hkd/LGMobileDriver_WHQL_Ver_4.0.4.exe.htm
ii) Download the LG Bridge software from here: http://www.lg.com/us/support/product-help/CT10000025-1438110404543-preinstall-apps
iii) Remove the battery and reinsert it so the device it is fully off.
iv) While holding the up volume button, insert your USB cable.
v) You should enter download mode. Go to the Software Update tab of the LG Bridge. It will say connecting and then should say your device is up to date. Click on the recovery text on the bottom right and then follow the instructions. The software will download the system image for you and this is roughly 1.6GB so make sure your firewall doesn't block this connection.
I've searched everywhere i think..before i posted the question
The phone wont stay in download mode....
It shows the little box with download and then the error i mentionet above and restarts..
And means SEA mobile?

FIRST install the DRIVER from this thread: http://forum.xda-developers.com/showthread.php?t=2785089
See in the part 2015 with TOT files...
(if any other drivers are present, uninstall them and do a clean install)
You need to get in Download mode to be able to fix it without having to open the phone.
1. Unplug phone from pc and power off
2. Remove back cover and remove the battery
3. Plug the micro-usb cable into the phone
4. Press and HOLD the VOLUME DOWN (make sure you press it from the edge, far from the powerbutton)
5. Put the battery - Dont let go of Volume Down yet.
6. Connect the micro-usb cable to the pc - Dont let go of volume down yet
7. Wait for the pc to recognize it, and the download mode appears on the phone, now you can let go of volume down
Repeat again, first time might not work.
