QPST files (.HEX) for Desire HD

Hello,
A friend give me a bricked Desire HD. But my pc can recognise it at qualcomm modem (QHSUSB_DLOAD) when connected in USB (no led charger, no screen on phone).
After a lot of reseach, I've found the qualcomm QPST program. Have someone already try it ? Did anyone have some Desire HD's files for flashing ? (HEX or BIN files for QPST software download) ?
Thanks for your replies.

Any QCN files available for DHD ?

can you connect your phone and run MTTY?
1. Pull out the battery of the phone.
2. connect your bricked phone and power it on
3. connect with MTTY to diag port COM#: (look up # in device manager)
4. Type "h" and Enter to see if you got something back.

Hi massivekid, I've sent a PM (a bit unrelated to this thread, but close ), could you please look into it. Thanks.

even if my phone is correctly recognize by the pc, mtty can't connect to the COM port. Nothing work and JTAG flash seems to be the only way to make the DHD resurrected...

I'm searching for them too.
Phone stuck in download mode.

There're special drivers for flash mode and you must install it

If you installed drivers and nothing worked you can try tick "TA" just like the picture

[Q] how do I unroot vk810 4.4.2 and return to stock?

how do i unroot VK 810 running 4.4.2 and return to stock?

I am a MAC user...so I need to do this using a mac if there is a way...

I don't think there is a way on Mac. The LG Mobile flash tools are all Windows as far as I've seen. Can you use a PC at a public library? Use a friend's?

I finally got it to recognize the device, but all i get is "Upgrade tool is preinstalled in your phone. Please allow to install "Verizon Wireless Software Upgrade Assistant" when the phone is being connected to the PC" then there are no options for me - everything is grayed out.

Did you choose "Options" and then "Upgrade Recovery"?

LG G4 Problem with driver

Hello guys!
I am trying to update my LG G4 to Android Marshmallow but no success.
I am doing everything as is wrote in guide, I tried to search internet for help and nothing works
When I reboot into download mode, pc does not install drivers.
I have latest LG Drivers, LG Flash Tool 2014, KDZ file, Windows 7 64-bit
I am using original USB cable, different cable, different ports, latest drivers (tried also older ones)
I tried to restart PC couple of times as well as my phone
I have got this error:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
This is how Device Manager shows my device in download mode:
Tried also manual installation of drivers:

i have exactly the same problem..... but i think that something happend when i trait to use the LG Flash tool..... before i try to update... my drivers have been working fine

@nothingfacey yes me too and its normal he recognize on bridge for example .and when you try to flash for roolback you cant . first bcz there are anti rollback on the motherboard and second because for the moment the flashtool need to be update because the dll on the kdz is not the same

I am having the exact same problem and I have yet to find a fix.
I noticed that I could get ADB to temporarily work after switching to/from MTP/PTP mode multiple times randomly with unplugging/replugging. It would be interesting to see if anyone has found anything reliable.

Have you tried LGUP? That does everything automatically.

Can you reboot your phone into recovery mode? Or download mode again? Then you have a chance to get it fixed by flashing a new firmware.

No, it doesnt even vibrate, i have installed the drivers and now detects the phone as Qualcomm HS-USB QDLoader 9008

I have the exact same problem... Trying everything at the moment. Its totally dead to look at . No sign on anything. Not even LED lights. Only reason i know its running is because my computer detects it when i plug it to the computer. Been messing around with the Qualcomm progz called Emmc software download app, QPST configuration, QFIL and Memory debug app... But i got seriously no clue on what to do. But the programs detects the phone and they all tells me its in download mode no matter how i try to bioot it. Not even Odin can see anything.
Hope to get a solution
