Need a new Motherboard? Or at least some help - Nexus 5 Q&A, Help & Troubleshooting

I'm wondering if anyone has a Nexus 5 D821 motherboard in working condition that they would like to get rid of. Or if anyone knows of a way to get into Qualcomm 9008 mode from LGE Android Platform USB Serial Port. The phone seems dead, doesnt react to button presses, Vol Up+Vol Down+ Power doesnt change anything, the phone restarts back into LGE Android Platform USB Serial Port mode. No download mode. From what I know my EMMC wasn't dead (passed all the Board Diag Tests). Phone died after I flashed SBL1 with boarddiag (Even though I was told not to...)

There is a guide in general forums.

I hard bricked my phone yesterday and was stressing out quite a bit! Luckily I found this guide: http://forum.xda-developers.com/yureka/help/question-qualcomm-download-mode-k-t3068040
Note: I assume that you know what you are doing. Since you know about Qualcomm HS-USB QDLoader 9008 mode, you probably do, but you can do some serious harm with this mode.
Essentially, the gist of the guide comes down to installing the qualcomm drivers so that the phone becomes detected as a Qualcomm HS-USB QDLoader 9008. After this, you can use Boarddiag as you are used to to reflash the partitions. Note that for me, the phone was not in sahara dload mode and Boarddiag would not work. What I had to do was the following (these steps are done after the drivers are properly installed)
Unplug the Nexus 5 from your computer
Open the back cover and remove the 6 top screws holding the other protective cover
Disconnect the battery cable for 5 seconds. Reconnect it after
While holding the volume up and down button, plug it into your computer. It should now be in Sahara download mode and Boarddiag should work.
Let me know how everything goes!

Nexus 5 won't boot nothing on the screen, no recovery/fastboot, QHSUSB/LGE AndroidNet

Hello guys,
My Nexus 5 (D820 32gb) wont turn on, after flash a false (I believe) file in TWRP, when i press more than 10 sec or less nothing appear on the screen (he was off) he was recognize by my PC sush as QHSUSB Bulk (I have a driver for Find 7 but I believe that is not 100% compatible, when I install the driver "QHSUSB Bulk" is converted into "Qualcomm HS-USB QDLoader 9008 (COM16)") when I press on power+up+down, when I press on nothing my pc recognize my phone sush as "LGE AndroidNet USB Serial Port (COM15)".
On LGNPST a UNKNOWN model was recognize when my phone is on "LGE AndroidNet USB Serial Port" but I don't have any dll and bin file for "emergency" the phone (D820 32gb), I think LGNPST is the only software to recover my phone.
Please help me.
Thanks

Once this state is achieved on a Nexus 5, there is nothing we can do about it yet, only LG or other professionals can repair it. Even so, in most cases LG does not bother to repair it and simply does a motherboard swap.
Sorry, but you'll have to send it in for repair/replacement.

F***, it is no longer recognized by the pc (fail when flash with LGNPST), so for next guys who read the topic I think this program can restore a hard brick from nexus 5 : http://forum.xda-developers.com/attachment.php?attachmentid=3007071&d=1415553921

Nobody here has ever successfully unbricked a Nexus 5 after it has been to 9008. Attempts have only resulted in being completely dead or a unrecognized device.

[Q] Battery swap failed : Question mark appears on screen

I tried to replace the battery on my Nexus 5.
powered it down and opened it up. actual swap was done without incident​Now the phone does not recognize neithe of my batteries (old and replacement). I can boot it into bootloader just fine by plugging it in a charger, but the screen will show a battery with a ? in it when trying to boot the phone.
When I plug the phone in my PC, it will only get recognized as Forge HS-USB QDLoader 9008 (COM3) under PORTS in Device Manager. I've tried the diag tool here: and all tests look fine.
Rooted, bootloader unlocked, ElementalX kernel, 5.1.1
Thanks for any help!

Yes,it will not show up Qualcomm HS-USB QDLoader 9008 in device manager,seems to make no difference what drivers i download,seem convinced there is something not right with the phone.
That's right what it shows QDLOADER 9800 what phone you tmo or international\india version

I have the oneplus 8,i have tried a different pc,with the same results.Both pc's recognise the phone,and i can transfer files accross,it will just not show QDLOADER 9800 in device manager.
The phone must be completely shutdown before the cable is inserted.
1: power phone down
2: start your msm app and have it ready
3: hold both volume up and down at the same time and do not release
4: plug USB cable (that is already attached to the PC) into the phone
Your phone will not show any indication that it has powered but you should see it in the MSM tool as well as the device manager.

Have tried this countless times on two different pc's,it does not show up on msm or device manager.Also the when pressing and holding said buttons the phone will sometimes go into fastboot mode.
Try the following, power up your phone let it boot, if is finish with booting plug in your phone with the USB cable and look whether USB debugging is showing in status bar at the left bottom of the screen. If it shows USB debugging open CMD command window and type "adb reboot edl" and see what happens. Before you should start your msn tool that you can tap the enrum button maybe this works
Sorry,bottom of which screen
The phone shows in device manager when powered on and connect to the usb cable as " universal Serial Bus devices - IN2013,then when i try and go into edl mode the device manager does not see it's connected.

HOW TO UNBRICK THIS LG G2?

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.

Question oneplus 9 got blacked out during flashing fastboot stock rom what can i do now

please read title and help
restore it with msm tool
how to connect the phone screen is black
If the screen is black it may already be in EDL mode. Plug it into a computer and check device manager for something like "Qualcomm HS-USB QDLoader." If that's there, you just need to get the MSM Tool for your model and make sure you have the right drivers.
If you can't get it into EDL mode, you will have to file a warranty claim with OnePlus, no other choice. Mess around with the buttons and see if you can get it to reboot or try the EDL key combo (hold volume up and down and while holding plug in the USB cable that's plugged into the computer). You don't have a chance of repairing it yourself if you can't get into EDL, end of story.
pc recognizing this Qualcomm HS-USB QDLoader in device manager but in msm tool it is showing n/a.and also in device manager it is showing triangle error on device.i am using official driver provided by msm tool poster.
Need some help unbricking (solved)
I bricked my OP9 doing some stuff today. It will not turn on, access bootloader, or anything. When I plug it into my computer, it makes a connecting sound, waits 10 seconds, then disconnect sound, then repeats the process. I tried using MSM...

It's can help you
Well you're not the only one I guess. That happened to me as well. So perhaps, Alhamdulillah I can help you out
The screen still remains black that means your phone is in the EDL and you'll need to get it out of it and then get back to EDL again to use msm.
Anyway, hold the power + volume up + down all simultaneously for a while. It'll take you to the Fastboot mode. Don't worry, it definitely will take you to the Fastboot mode.
Then you can do the rest of the flashing as you wish
