My g2 stuck at fastboot mode

Hi all,
I'm really desperate because my LG stuck in a boot loop and it can only get in the download mode.
I've read the thread about using fastboot command to restore to stock but my condition seems to be a little bit difference
First
i've got these command while plug my phone in
[860]fastboot mode started
[1070]-reset-
[1080]-portchange-
[1150] fastbootrocessing commands
Normally there would be a [910]udc_start() in the second line but i don't have it
Second
my command such as fastboot reboot or fastboot erase all stuck. When i unplug the usb cable it appear the too many link line like this
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Is there any other way for me to return to stock or i can't use my phone anymore?
Note: i've tried to change the usb cable, usb port and even another computer and all of them stuck at the command line.

I'm sorry but I meant to say Srk Tool. you can find it here http://forum.xda-developers.com/lg-g2/development/tools-srk-tool-useful-toos-lg-root-twrp-t3079076 . Once you download the tool open it up and go to fixed utility (4) and then press fix fastboot.

i cant cuz pc do not recognize the phone and the download mode wont start

I suggested LG mobile tools because, from the screen shot, it looks like the phone is in download mode.
Unfortunately, I am not able to offer any other advice as I have only had my 802 for about a 3 weeks and I haven't run into a problem such as yours.

Qhsusb_bulk mode allows you flash your partitions using srk tools and will fix your download mode so that you can flash a new ROM and remove your brick.

Apps Watchdog Bite!
DemiGod Crash Handler : Apps Watchdog Bite!
Press key to choose Dload Mode or Reboot
1) Volume Up: Dload mode
2) Volume down : reboot
If you choose Dload mode please do following action
1) Dload Mode, please connect usb
2) get the ram dumb image using QPST Configuration
Board info:
rev, 1.1 speed.pvs : 1,2 serial : 003455520e08aba8
if it something tells you it would be cool. i tried to go download mode but after it says "entering download mode" its something like lag and i cant do anything. Also tried combo (on turned off phone) power+vol up so korean lang appeared. Sorry for my bad english, hope u understand what i told.
And btw wondering how prev owner just installed Cloudy 3.3.. cuz he had same problem with this kind of brick, but he didnt answer me
edit; now i can be in mode in what i can't see anything on my lg screen ( pure black) and if i plug in my usb cable i see mass of partitions along with " switch off qhsusb_bulk" what to do ?

Qhusb bulk - refer to 'lg g2 fix no download mode, no recovery' and use SRK TOOL by somboons

Hey guys. still got problem. It was flashed succesfully (SRK tool to fix dload mode + .tot files) had 4.2.2 android but sometimes it was rebooting and catching bootloop and sometimes it booted succesfully. Tried to fix it by LG support mobile tool, and it was closed to finish repair my firmware but when it rebooted into download mode (progress was like 13% it went into qhsusb bulk so it was interrupted. Now when i boot my g2 i see in right corner small letters like error security boot then it goes to white window ->

That is the problem i don't know how to enter the QHSUSB_BULK mode on my phone because i can only accesss fastboot

Have you tried erasing about, modem, persist... partitions, and then flashing the appropriate images?

i cannot im affraid. Bootloader is locked, and i cannot unlock it.
When i try to unlock it says that i need to enable oem unlock but i have no android installed..

Actually it's not qhsusb_bulk mode that you need, you need QDloader mode which can be accessed through the qhsusb_bulk mode. If you run Windows,
#1. CMD(admin)
#2. bcdedit.exe -set load options
DDISABLE_INTEGRITY_CHECKS
bcdedit.exe -TESTSIGNING ON
#3. Reboot your computer keeping​ your phone connected to the computer
#4. On booting go to device manager
#5. You should see a new device entry with QHSUSB_BULK under Qualcomm devices(or any other Qualcomm entry)
#6. This is the QHSUSB_BULK mode that you can use to get into QDloader mode using appropriate drivers, as in the links I posted.
I'll look for more info, if I can help you?

Try going through the process of unlocking bootloader....and I have a feeling that it will work, since you don't need to boot your phone for unlocking the bootloader. You can find guides for that....

ill try the steps. But the unlocking is not going to work because the first step is use
Code:
fastboot oem get_unlock_data
returns this:
so i cannot unlock my phone by the official way.

Then I guess you will need to jump through all those hoops...

none of those show up, because i can only boot into fastboot not the black screen with flashing light.

Did you manage to fix it?
Did you manage to get your phone fixed? Mine is doing the same thing you said, I can not flash anything, and the "qualcomm unbrick" guides do not work for me, I dont see any Qualcom Loader in my Devices Manager, but I do see an Android Device when I plug it to my pc.
I can only get to fastboot mode, can not flash anything, my bootloader is locked, and it trhows the same error (read datablock error) when I try to unlock it.
Thanks in advance

same situation

Could you solve the problem friend? I am also in that situation, greetings

Try to choose QCOM mode in a bootloader

I too had the same problem and solved it.
You can't reboot into bootloader so can't flash stock firmware. I had the same problem and was able to solve it using few tutorials.
Here is a youtube video to solve this problem: https://www.youtube.com/watch?v=m2NqpY6X-X4
Watch the entire video. He had a proper running device and then purposely bricked his device to bring into the same state as your device.
Then he solved it.
Here is the xda thread that was used to create the above video: https://forum.xda-developers.com/moto-g4-plus/help/solved-unbrick-hard-bricked-dead-t3585016
The above video was made using this xda thread and I am not the owner of the video or the thread.
I would suggest watch the video and follow it as its more continent.
Note: there was a step in the above mentioned thread which was to be done. I did it and faced problem (the computer then didn't even recognize the device as qhsusb_bulk and showed "usb device not recognized"). Had to reset my pc and then skipped that step. That step is also skipped in he youtube video.
These are the two lines which I skipped writing in cmd and it worked:
bcdedit -set loadoptions DISABLE_INTEGRITY_CHECKS
bcdedit -set TESTSIGNING ON

Did you try unlocking the bootloader? If you are able to do that then you will be able to flash. I don't know why device is unable to flash stock firmware with locked bootloader

I had to buy another phone! I just couldn't fix it in any way.
I even took it to a guy who works fixing phones, and he said it had the motherboard bricked! And there's no solution for that, other than buying another board (expensive!!)
