H815 Bootloop, No download mode, 9008 everything - G4 Q&A, Help & Troubleshooting

For short, i bought the phone from the grey market so i have no warranty no nothing.
The phone bootlooped after 5min of use. I managed to get it up in the freezer and unlock the bootloader, installed stock 20C with the 1CPU active at boot mod. All went fine for 1 week untill the phone literally died while i was watching youtube. I managed to boot it in the freezer BUT i got 20~ seconds of bootloop then Demigod Kernel crash etc. green screen and Watch dog green screen.
I got my phone into download mode and started flashing 20C again but the phone bootlooped during the installation. After that the phone literally died (again, season 2 out of 10 xD). Back in the freezer... PC recognized it as QHSUSB_Bulk, i installed the qualcomm drivers and it appeared as Qualcomm HS-USB QDLoader 9008.
I tried QFIL with 1000000 files i've found on forums, all failed ofc.
I used Win32DiskImager to write"EMMC_ROM1_032G74_1803230737_00000000_20000000". The phone started to bootloop (at least it wasn't dead anymore) and bootloop in download mode. After few bootloops it dies and goes into Qualcomm HS-USB QDLoader 9008. Freezer or won't even turn on.
Then i used Win32DiskImager again to write system.img that i've extracted from my original KDZ (Europe H81520C_00_1218). The phone did almost the same thing BUT i've managed to flash the .tot file that locks the other 5 CPUs and the phone boots, "Android is installing 2 out of 31" or something then reboots into bootloop again. If i try LGUP with my original KDZ it reboots at like 27%~ during System phase or GPT Partition.
Any way i can recover from this endless bootlooping and 9008-ing? It's so cold in the freezer... i want to get it over with before i get sick xD

Up up

Up again maybe? No one?

What do you mean by you can't get the driver for Qualcomm 9008 mode?

I have the same problem with my LG. It has red LDI, but I think that's the battery problem. Try to change it.
if you unplug the battery, and put it back in, then hold the up button while plugging in the usb cable, can you get into Qualcom mode? I bricked my phone last week and i was able to get into qualcom mode that way. I then also installed the qualcom drivers and rebooted my pc. I used boarddiag by Willcracker and was able to recover my phone to a boot loop which allowed me to get into Download mode, which I was able to recover the phone back to stock.
Not working for me, still LGE USB Net. When I test point my G3, Windows show notification 'Not recognized'

LG G3 D850AT Bricked and Reset but continues to become bricked

I was trying to install TWRP on my LG G3 (D850) and somehow got it so it would only show up as a Qualcomm HS-USB QDLoader9008 Device on my pc with no screen on and no way to get to any DL Mode.
I followed the directions from http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/ and used the LG Smart Boot Diagnosis Tool (1.3.1) to get it back to be able to boot but as soon as I run the LG Flash Tool again and it resets I'm back to the no screen and only being identified as a "Qualcomm HS-USB QDLoader9008 " device via USB. I have done this 3 times now and still getting the same result. I rerun the Anti RollBack software and then try to flash again but it always does the same thing.
Is there something I am missing?
Thanks

LG G3 Hard Brick Solutions

1st- try the following method
http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
2nd- you fail to unbrick or the following error occurs
>>>> EMMC test fail
this is due to dry soldering of EMMC chip
in such case use a HEAT GUN and give heat on the EMMC chip...
leave it for 30 minutes then insert battery and plug cable into phone while hold volume up key.
hope: it will be booted into download mode.
>>>> NOW install the stock tot & dll.
NOTE: DO NOT OVERHEAT THE MOTHER BOARD OTHERWISE IT WILL BE DEAD
i also had the same problem with my LG G3 (F400K)
i tried a lot but failed some time it was booted into download mode and failed to install tot & dll at 99% or sometimes 6%.
after removing and re connecting battery, it show QHSUSB DLOAD 9008 & never booted into download mode.
after 30 to 40 minutes it was being booted into download mode and so on.
i used a heat gun and NOW MY LG F400K IS WORKING FINE AND USING CUSTOM FULMICS ROM 6.6
Is it really emmc problem? I have the exact problem like you describe. Like hard to boot into download mode.
Even if it does it will fail at flashing using Lg flash tool.
Sometime boarddiag would give me emmc test fail. So, i have to re-short over and over again.
Also If i use different firmware like vs985, with just single attempt boom it boot into download mode.
Btw mine is D858HK

Sudden Death of the Nexus 5X on Oreo

Hi guys,
I am not sure what exactly happened. I was sitting around and listening to some music when my old Nexus 5X suddenly rebooted and stayed blank.
First guess - Battery. But that turned out to be quite wrong as I had charged it over night. Tried to get into fastboot mode or recovery mode; After the logo showing up and my beloved "This device isn't trusted" sign the screen went completely blank and that was the last sign of life. As it's got an USB port, I hooked the device up to a computer, found it to identify as "Qualcomm HS-USB QDLoader 9008".
Some research showed me that this is some kind of download mode, in terms of 'nothing works anymore' and you'd have to get your hands really dirty here to get at least somewhere.
So my educated guess would be bad memory or some corrupted filesystem and I'd have to reinitialize the phone to be able to fastboot or anything.
Tools already looked at:
LGUP - No joy; Device not found as this one requires something like a basic recovery mode which seems to be broken here
boarddiag - I was able to read from the memory using 'download' using a tot file I found somewhere online.
QPST - Found some prog_emmc_firehose_8992_lite_lge.mbn file, but I lack the patch and raw program files
Any ideas out there getting that bugger alive again?
Cheers
Rei
This is not a sign of download mode, your device hardbricked. As you have the firehose (I don't know if should work this) I found from another thread there the other files for QPST. I didn't tried that because this was released after I send my 5x to service (yes, for second time) due to hardbrick . https://drive.google.com/file/d/0B5EP5AzZNQxPcE52QWw2VloteUU/view

Nexus 5X Hard bricked?? No bootloader, no startup, Qualcomm HS-USB QDLoader 9008 HELP

Hi,
After I took a picture with my camera, my Nexus started to go into a bootloop. I forced it to shutdown by going to the bootloader and choosing shutdown. I later on wanted to start the mobile, but it would sometimes just crash instantly or show the google screen and crash. I tried flashing a 4 core boot image, as that might solve it, but instead it wouldn't boot either. I also had to flash a TWRP recovery optimized for the 4 core boot image. If I finally got into the bootloader, selecting recovery will just crash after a few seconds. I tried to flash the 1 core boot image, as I hoped that might solve it, but made matters worse. I cannot start it, nor can I get into the bootloader. When I connect the phone however, it shows up as an Qualcomm HS-USB QDLoader 9008. I tried LG UP as suggested, but that doesn't recognize my phone. I decided to try LG Flash Tool, but it will always fail..
I don't know what to do anymore, please help!
