Hello, I will describe my problem as follows
After using my cool1 for a month with no problems i decided to flash JUI 7.0.1 (with gapps etc...) on my Cool1 via TWRP but after doing it i realized it has many bugs and apps doesn't work properly. So i decided to return to EUI. After flashing the original stock firmware and rebooting the phone automatically switches off.
Power button not working, i cannot get into recovery and i tried all combinations of buttons without success.
When i connect it to the computer the red led start blinking and my computer recognizes it ONLY in Device Manager as QUALCOMM HS-USB Diagnostic 900E (COM3).
i have all the latest drivers installed.
i tried QFIL and it also recognizes it as QUALCOMM HS-USB Diagnostic 900E (COM3) and after setting everything when i click "Download" i get this error:
Start Download
COM Port number:3
Switch To EDL
Download Fail:Switch To EDL FailFailed to Switch to Emergency Download mode
Finish Download

MiFlash doesn't recognize the phone so nothing to do
Coolpad Download Assistant doesn't recognize the phone.
Any suggestion that would help, please... I think it's hard bricked because it cannot get into recovery nor the fastboot mode. completely dead only Red led blinking and QUALCOMM HS-USB Diagnostic 900E (COM3).
Thank you
*Let's all be nice. If you won't write for me, show me the right places, and i'll thank you. And please thank me too if I've helped you.

Sorry but that's the only solution. The one I've wrote on xda.
In fact its quite easy, the problem is when we ended up without it we stressed
For the first time it took me 1 month but then, after that experience, I've manage to make it work after 5 min. And believe me, since the first time, I've broken mine more than 20 times

No flash programmer. I ended up unlocked the bootloader with my custom image (its already posted you'll see it) and tinkered around but zeroed out sbl1 in hopes of qcom 9006 mode but thay wasn't the case

I may have found a flash programmer that may work. I've yet to try it (I have an EDL cable) so I just need a week or so till next Saturday till I have my computer back. If it does work I'll already have the EDL firmware made
Looks like the Zone 2 has a flash programmer (MSM8610) prog_emmc_firehose_8x10.mbn (also for other chipsets of this kind) that will be able to be sent to the device. I will tune back in this weekend with results and if success a new EDL restore thread for the Zone 2 will be made
Hi everyone.. Can someone guide me how to get my phone to be detect back as Qualcomm HS-USB qdloader 9008 instead of this Qualcomm HS-USB Diagnostics 900E.. Actually i was flashing a rom using miflash but since i didnt select flashall below.. i made the mistake of closing the miflash before the flashing was done.. Since then i cant get the mob to be detect as qdloader so it can appear in miflash. The phone right now is still in fastboot. Please is there any way to revive my phone? :crying::crying::crying:

This works for people who are able to get to fastboot. I am not able to get to fastboot at all. Only EDL. Please help. Any other alternative?
Can you please check this thread.
I hope this helps.
You remind me of myself
I did the same thing in April and had to go to service center as i couldnt make it work that time, they fixed it within 24hours
But now there are lots of recovery methods that u could try

Try deep flash methode, just need to buy deep flash cable in market. For the guidance, please try to googling it in miui forum due to already available there.
Yesterday, one of my friend succesfull to restore her kenzo from diagnostic mode and really happy with the result.
Try the simple deep flash method mentioned here -
http://en.miui.com/thread-310325-1-1.html
I was able to recover my rn3 from 900e mode using this.
It's very simple and easy. You just need a copper wire strand to do it.
Use Deep Flash Method
I had the exact same problem so I tried deep flash method. It worked and my phone was detected by the PC as 9008. Then I could flash the fastboot rom using Miflash tool. Hope this helps.
Hello,
I super hard bricked the Phone from my Brother and he need it for work. I flashed the wrong Stock-Rom.
No when I connect the Phone to the Computer it appears as Qualcomm HS-USB QDLoader 9008.
Is there anywhere an Option to repair it?
Thank you for your attention.

Not sure with LG maybe lgup or 1 of their tools, I saved xiaomi device as long as pc recognises it should be a way, update Qualcomm HS-USB QDLoader from device manager and restart pc disabling driver signature varification. I had to put the phone in download mode.Thats best I can do someone with more knowledge will better explain. When PC doesn't find the phone that's the end without special cable, remove any sharp objects near your brother ��

Have you not got a recovery installed anymore?
I Can do nothing. It wont Turn on. The only thing is to plug it into the pc
have it powered off
hold powerup and connect it to the pc
does it start in download mode?
if yes you should be able to upload the stock rom with lgup
Keep us posted how or if you can resurrect the phone.
Can't Go to Download Mode still recognised as Qualcomm 9008

If you can't re-flash a stock ROM with LG UP, perhaps you can take matters in your own hand. But you have to viod the warranty for this. Also, you have to be able to enter fastboot mode.
Since you are from GB, I assume that you have the European H850, which can be bootloader-unlocked.
If so, you can try the following:
- Unlock bootloader
- Flash TWRP
- Flash the complete 10E ZIP file
I don't know if this works, but if your phone is messed up anyways, you can as well try this before throwing it away.
I can't do anything no charging, no turning on. Nothing. The only thing is that it is recognised as Qualcomm
Fix guide for xiaomi
If it's possible for xiaomi can't see why there isn't a way for lg.

Did you try this
http://www.androidbrick.com/ultimat...agons-are-unbrickable-qhsusb_dload_qpst_qfil/
Sounds like you can use miflash/xiaomi tool for any qualcomm snapdragon device.

Bumping
Yes, but the tool are not for the phone and won't recognise it
you didnt specify what happens when you plug in usb. the only thing you said was that you can do it instead of turning on or anything else.
When i plug in the phone the phone is still dead only the processor will be recognised. I need a tool to flash the software through QHUSB. I found boarddiag but no systemimage.tot File for the phone
Follow these steps:
1. Remove the battery
2. Put back the battery
3. Hold the volume Up and connect the USB
What happens after that? Do you have the "firmware update" screen on your phone or is still death?
Still death

Hey check Windows Certificate Manager (certmgr.msc). Remove ANY Certifications with "USB [something] TEST003" from "Trusted Publishers and Trusted basic certificate something (sorry I have to translate it but it is the 2nd from Current User Directory.
If you have ANY Quallcom drivers (uninstall it).
Find Qualcomm HS-USB QDLoader 9008 device under Ports (COM & LPT) and note the COMxy port (in my case it is COM3).
the same happened to me, you could solve it if you were telling me how please ...
the same happened to me, you could solve it if you were telling me how please ...
I think is possible to recover the LG G5 with this tool, but require a full compatible rom in that format, impossible to find.
Here another LG G5 bricked without the "Download" mode screen, only recognizer in USB with "Qualcomm HS-USB QDLoader 9008".

It's hard bricked.. Same happened with me... Use a deep flash cable or try short circuit method to boot into Edl mode and flash fastboot ROM.
(Google the terms you'll get to know better)

You should use a deep flash cable to boot into Edl mode (you can search on the net for how to make a deep flash cable.. Or you can order one online)...
And there's one more method in which you have to remove the back panel of your device and unplug the battery and short circuit it by connecting the positive and negative terminals on the motherboard.(i have seen on YouTube but didn't try because we have service centres here, they repaired me free of cost)
Try using deep flash cable method.... It's easier and less risk prone....
