Thanks, I've read this post and I will stop the screen that you place else, as if something was missing in the program or you must connect the g3 via RS232 serial ...

Hi. I just quoted what I read. I `be never been in your situation. I think you should keep searching.

Test point for LG G3 to force into Qualcomm 9008

I have a LG G3 D850 that is bricked. When I go into download mode (Volume up + USB plugged in), phone display shows "download mode" then goes black. On my Windows 8.1 it shows QHUSB_Bulk in device manager. From I have read, you need to force the phone into Qualcomm 9008 mode by shorting the test points. Does anyone know how to do this?

It must Jatg .....

LG G Pro E986 Stuck in boot loop, no recovery no download mode, Help

So yesterday i tried flashing super LTE lollipop and being the stupid person that i am i flashed the E980 version instead of the actual version E986 (which i found later by removing the battery :| )
When rebooting the phone the home button is constantly on while the screen backlight turns on and then off again and again.
No lg logo, no recovery and no download mode.
Only when i plug in the phone to my pc it detects it as lg androidnet usb serialport and not Qualcomm HS-USB QDLoader 9008 like in other threads. Can i still get stock rom back? help much appreciated.
Edit: Okay i don't know why but apparently when i pressed vol + and vol - simultaneously and then connected the usb to pc despite showing a black screen it actually was download mode because using Lgflashtools i managed to install stock jelly bean. And i thought i was full hard bricked :/

reserved.
mine is detected as Qualcomm HS-USB QDLoader 9008 but nobody has achived to get live my OGPro...

Have you found the required TOT file and DLL?
I am having the same problem with LG G Pro e98820c after flashing wrong rom and unplug USB during flashing process.
Now the phone is stuck at Brick qualcomm hs-usb qdloader 9008 mode. I have some tools such as Smart diagnosis tool, BoardDiag, Androidbrick, Qfil/QPST ....But I have no proper guide how to use them to unbrick qualcomm hs-usb qdloader 9008 mode.
Have you got a solution for your brick phone.
Thanks , Sho Thant.

I tried each and every version of Mi Flash tool but not the first one. On each versions the Qualcomm HS USB qdloader 9008 changed to 9006 but after 4or 5 seconds the loader reverts back to 9008 and the error happens.
Will try the first version of mi flash tool. Thanks.....

LG G8 STUCK IN Qualcomm HS-USM QDLoader 9008

Today I Bricked My LG820Qm
I was updating my Lg g8 using LG UP, When the Process on 64% my PC power off
After that my phone stuck in Qualcomm HS-USM QDLoader 9008
Any solution to come out from this mode to Downloaded Mode so that i can update using LG up.
I was updating G820QM10i_00_NAO_US_OP_0401 to G820QM20b_00_NAO_US_OP_1224
My LG up LGUP_Lab_Frame_Ver_1_16_0_3

Can you try to switch to download mode by press&hold VOL+ while inserting the USB cable (connected to PC). Phone needs to be off while doing so.

I tried not working
If i press&hold VOL+ while inserting the USB cable still my phone come with Qualcomm HS-USB Mode
thanks for your reply

What happens if you press&hold VOL- (furing the whole procedure) push the power button until the phone vibrates, release the button und press&hold the power button?

Which ever combination, Vol- + power phone power of
with in sec it boot to Qualcomm mode

I don't know where to ask so I'm gonna try here. My G820N is stuck on Android 10 beta. Whenever I flash an official kdz, it only allows for emergency calls. Can't do anything. Any help would be appreciated

Following, in right here with ya.

Try entering download mode with phone disconnected from USB cable.
Also try to see if it gets recognized by LG-UP or by LG Bridge. These 2 softwares don't need download mode to be able to flash, just the phone to be recognized on some PORT.
Try also factory reset hard menu. Also try switching between Slot A and Slot B. There is also this backup method. Phone is not dead on one of those slots.
If nothing works (but slot a slot b should 100% work) , wait for the firehose, it's just around the corner. That will restore the phone back 100%.
For more info search v50thinq on telegram app. :good:

I can t get to download as it freezes and without the USB cable it doesn't even try and enter. I appreciate the recommendations. I was thinking of the a/b seit hbut without the use of fastboot I am at a loss of how to switch between the two as I thought the system chose and the switch happened upon rebooting once a system had been selected ie as in turning the unit off after loading the os set a flag to go to the opposite system upon completing the inftframs and boot sequence.

So, if the device, as you say, lost power during an update like that, then almost assuredly you have at least one, if not numerous corrupted partitions.
And, it's specific partitions on the device that allow it to enter download mode. One of these most know about or have heard of is the laf partition. But other have to be there also for it to work, I don't remember exactly what the others off the top of my head, but that info is easily found.
The key thing you need (or any others commenting same prob), is to be able to enter EDL mode and have qfil installed and recognizing the device. If you can get that far, it would be easy to find the correct partitions you could flash with qfil and then immediately go from qfil to download mode.
Many many people have done this. Just get qfil set up (see guides section) and get the device recognized. that takes some effort but it's def doable.
