Hello,
I think my Samsung Galaxy S4 - GT-9506 is Hard Bricked. Screen is black - regardless if i press the power-button, home and Volume-Down or Up. Odin didn't recognize the Phone. But i installed OPST cause the phone was recognized as Qualcom HS-USB QDLoader 9008. When i start the QPST Software Download Program it tells me that there is a phone connected to COM6 in Download Mode. I think this is a good sign but i don't know how to use QPST and I also have no recovery Image for QPST and my GT-9506. Can somebody help me?
Nobody here who can help me?
I'm trying to connect to my device using QPST, but the device is not showing up in the COM ports. I've tried to delete all the usb devices related to the device in device manager but all to no avail. And none of the dial codes I'm using seem to be working. Only ones that work are those that start with "*#*#" and end with "#*#*". Only com port I get is the default COM1, to which there is no phone connected. The other problem is that the drivers I have doesnt seem to be working, I even had to install them by disabling hardware signing. Device is not detected in download or recovery mode either.
Processor is a MSM8212 and the mainboard is MSM8610.
I'm on windows 8.1
Your device is in regular mode... to access DM you HAVE to have it in DM mode.... so try EFSpro to switch your phone into DM mode or you will have to keep looking for a dial pad code. Some handsets allow sysfs to enable DM mode too. Have a look and do some research. Your QPST drivers should come from the manufacturer... ie I am using samsung drivers to use the DM port, not drivers from QPST.
No Boot - No Recovery - No Download Mode Unbrick Guide
Qualcomm HS-USB QDLoader 9008 or Secure booting error (No Boot - No Recovery - No Download Mode) or "QHSUSB_BULK"
Hi team, if you have come here I'm sorry you are having this problem! But my friend and I have been to hell and back trying to fix this problem and we wanted to share our method of success for any poor soul who is experiencing the same thing! For our situation the USB was unplugged half way through flashing a KDZ or going back to stock firmware and created the No Boot - No Recovery - No Download Mode problem.
This has only been tested on the D855.. Just so you know.
First off, here are some links which you may need to have a look at if you have not done so already. Most of the bricking problems have already been extensively talked about by people here on XDA. For the method that works, we had to pull information from everywhere and spent a long time looking for the solution.
How to go back to stock - http://forum.xda-developers.com/showthread.php?t=2785089
Link for TOTs and KDZ's from the above thread - http://storagecow.eu/index.php?dir=Xda/LG+G3/Stock/

This is your last stop shop if everything is broken and nothing works, involves hardware fix - http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
The problem we encountered several times with all of the described methods above, is that many do not describe important things. While the main fix thread for the Qualcomm HS-USB QDLoader 9008 mode, which is shown in device manager, is very well written and detailed, the programs which are linked in this thread are questionable and haven't worked for many users with some offering to fix for money. We searched the internet and located a working version of the program which worked without giving a "Device was not found in dload trying to flash programmer" like the one provided on the XDA page. Use the links below for a working version from this thread http://androidforums.com/threads/lg-g2-not-turning-on-help.916865/
My first point is if you are having problems with any of the things, CHANGE YOUR USB CABLE or use the stock cable (I know most experienced users know this). The reason for this problem has something to do with different USB cables being made for different purposes and are of different qualities. Having an error on the USB ports gave us only qhsusb_bulk on windows device manager, without Qualcomm HS-USB QDLoader 9008 as well.
If you are still having problems, check your USB ports. It is really important to make sure this isn't the problem or you will be trying to fix this problem endlessly.
First attach the USB cable to the computer. When you plug your phone in, make sure you attempt to enter download mode by holding the volume up button when you plug the USB into your phone. Even though the phone will not enter "Download Mode" It will allow the phone to be detected by your computer (at which point you can release the buttons, it should then show "Qualcomm HS-USB QDLoader 9008" under ports. If this is not displayed you have a problem with the USB cable or port, or your phone is hard bricked and you need to head to the above guide for the hardware fix. If you have followed so far and are wondering what to do from here, once the "Main Fix" guide ends, head over to the "How to go back to Stock" thread above. Your phone should be showing "firmware upgrade" and you can proceed to flash a new updated KDZ on your device then everything will work and your nightmare should be over!

For all people with Windows 10 an problems with drivers (device is detected by Windows but app is not connecting). Decompress de correct cab for your Windows version, and update the driver "Qualcomm HS-USB QDloader 9008" with the path you used to extract. Now this driver isn't advertising that isn't signed anymore, and all apps will connect with your LG G3

Hi, I have the same problem, except that when I connect the usb, it shows up as "LGE AndroidNetUSB Serial Port". I'm not sure if I should try the Qualcomm route?

I just fixed my Lg g3 with this method. Not sure if it will work with AndroidNetUSB
Would like to help for any difficulties. (e.g. Not able to find TOT file) etc.
Thanks to @Orcam & @kryptonite
This did not work. Here's what I tried:
1. Without battery
2. Changed drivers as @shawe_ewahs says
3. With battery
4. Admin and non-admin
5. Changing COM ports
But, every time, I get:
"Device was not found in dload trying flash programmer
TEST Aborted!!"
My LG G3 D851 is in Qualcomm HS_USB QDLoader 9008 (COM 41) so I know it is in the correct mode! Agh, it is very frustrating. Any help is appreciated. Thanks.
Thanks you SOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO much! <3 I finally was able to fix my device *O*

No problem. Hope it didn't take you as long as it took us to find all the right stuff
I'm having this problem, but when I plug in without a battery all that shows up in device manager is "Unknown USB Device (Device Descriptor Request Failed)". I tried to do the hardware fix and was able to force the device to reboot by touching the pins. But all that happens is it disconnects and reconnects from USB without being detected properly.
I should note that when I turn the phone on right now, it stays stuck in the initial LG G3 splash screen. When I plug in without a battery, it shows an empty battery icon with a wire and a triangle question mark.
Any idea what I'm doing wrong? I think if I can just figure out how to get my machine to detect my phone as the qdloader hs usb 9008 I can figure out the rest.
The boarddiag v3.99 version 1 and 2 dont work, they dont even get ejecuted, not eve trying to execute as administrator.
Just wanted to reply since I resolved my issue. It turned out that, despite the apparent inability to boot into download mode, I discovered that if I booted up the phone with a battery in it and plugged into a windows 7 laptop, and held the button down to enter download mode, it eventually let me into download mode. I really can't explain why this worked, but just wanted to put it out there. It was at least a few minutes before I noticed that the laptop chirped and it was showing the install screen in download mode.
Hope this helps someone out.

Sounds like it may be a problem with windows from what you two have said. Perhaps compatibility mode is the way to go. They did release a pretty major windows 10 update since I posted this guide.
Hi, I have (or used to) the GSI Android P Rom on my A1, I saw that an update was avalible for it on the official Telegram group so I decided to download and install it, I wiped vendor as it said and flash the zip files, but I forgot to flash the vendor image again, I rebooted and now the screen is completely black, the phone is dead, the led is not making anything aswell, not even blinking, I'm trying to reboot into fastboot or TWRP with the volume keys but doesn't make anything, I tried to connect it to the PC and it recognizes it as Qualcomm HS-USB Diagnostics 900E (COM10).
I don't know what to do, I'm so worried about this, any idea?
Try to flash stock rom via miflash
If it says Qualcomm HS-USB Diagnostics 900E its not even dead. Lol
What to do next? Stop panicking & use that thing on top of your neck. It'll be fine. (& Use search button in xda, everything is here?)

Hi, what if now the PC recognize it as an unknown device?
Before your reply I tried to use Qualcomm emmc studio to fix it because MiFlash wasn't recognizing it, Qualcomm did, so I tried to flash the stock ROM but it gave me an error (something about couldn't found ram), I disconected it and it appeared as an unkown device, now not even Qualcomm can recognize the phone, help
Use edl method and you should be good
I have QXDM and QPST downloaded, but i cant find the qualcomn driver for diagnostic mode.
I found a way to turn diagnostic usb mode on through adb and this is as far as I've gotten any help would be amazing!
