HI GUYZ.
I had green screen on lg g3 d855 last day , and now I am trying to flash stock rom using Lg Flash Tool . Phone goes into Download mode and then Firmware upgrade but when it starts , after approx half of minute phone keep turning off. Hence, the upgrade failure.
I noticed that when I go into download mode , my pc detects the phone as "LG Device" ready to use , but when I start flashing the firmware , and it turns off , then Pc recognize the device as "Qualcomm HS-USB Qdloader 9008".
I assume that something wrong with Usb connection which keeps disconnecting after half of minute. even if you do nothing , still it turns off after same amount of time.
need your Help.

HELP NEEDED...
I Just installed a rom manager app then flash recovery thru Rom Manager..
then my phone restarted & freeze on lg logo... plz help..
The same happened to me, even when i put it to charge, it keeps rebooting (LG logo appears then reboot).
Even with the battery out, i've plugged into my USB and it keeps connecting and disconnecting. I've tried connecting it with the VOL+ pressed, it disconnects 2-3 times, and it remains connected; in Device Manager it appears as LGE Mobile USB Serial Port (COM12).
The drivers are installed; i've tried SmartFlashTool, i always get "We can't communicate with specific port"; i've tried LG Flash tool, nothing happens, it does not detect it..
Can anyome please help?
Drivers must be installed as in part 1 here

Uninstall all LG drivers and software first, restart PC then install as explained. You must be logged onto PC as admin.
Thanks.. At step J nothing happens (everything is as it's supposed to be until here).. i'm about to give up...

hi guys, (LG-P920 is my Phone)
yesterday i installed ROM MANAGER to install CWRMOD (or something like that).
Then i choose my Phone Type and flashed it. After that my phone permanent restarts in 1 second,
showing LG Logo and restart, restart restart nonstop.
I understand that i ****ed it up with flashing that recovery mod. So i decided to Plug into my PC
and install everything new, but when i connect my phone to PC , it detects a unknown device every second and does it permanently too. I tried the "Battery out, Volume Button UP and connect" trick, then it stops acting weird but my PC
dont recognise my phone as OMAP, it is just an unknown device
What should i do guys? i tried installing LG Support Tool, LG Mobile Driver, and i read all the Instruction to UNBRICK your phone.
But all the Instruction starts with a successful regocnition of OMAP driver, but my PC dont even recognise it as OMAP.
PLS HELP
ok i fixed it, it was a really complicated move to 0.1 sec click that omap and install while my Phone was permanent restarting.

I used the LG Flash Tool 2014 for my device to try to recover from a bricked phone. And I think i made it worse after using the kdz file and it completed 100%. I took the battery out and unplugged the phone when it was done. It wont even show anything on the screen now or go into recovery mode. But I do show RELINK HS-USB QDLoader 9008 (COM5) under the device options in my device manager when I connect the phone to the computer. Also it does make the device connected sound when I plug it in the computer. What can I do to get out of this mess? Thanks in the advance for any help that I can get.
Any help will be appreciated. THanks.
Hi everyone,
I have a second device as LG_G2 D802 and i gave it to a my friend. He said he rooted it and after a while bricked it.
Phone is not turning on normally, lights green and blue, LG logo appears and after a short while the phone is restarting. I can only enter download mode.
I've tried some options with using XDA topics but i couldn't solve it unfortunately. The last situation is: pc doesn't detect phone in download mode.
With short circuit, sometimes it seems as Qualcomm HS-USB Diagnostics 9006, sometimes Qualcomm HS-USB QDLoader 9008 in device manager.
I used SRK TOOL for 9006, it finished successfully but when i unplugged phone and plug battery and plug usb and enter in download mode, pc didn't detect phone, any devide, etc.
I used Boarddiag for 9008, AP TEST: Successful EMMC TEST: Successful SDRAM TEST: Successful, all process is successful. But again, in download mode, PC doesn't detect anything of the phone.
In the videos I watched, after successful SRK TOOL or Boarddiag processes, pc must detect phone in download mode but the same thing didn't happen to me
I used Win 8.1 64 bit and Win 7 X86, but same thing happened. Stuck in pc detecting problem in download mode. I installed drivers, too.
Is there anything that can be done about it?
Does anyone have an idea?
Thanks.
