H818P Unable to enter Download mode, fastboot works fine - G4 Q&A, Help & Troubleshooting

When i press Vol Up and plug in USB cable to computer, the phone starts with "Download mode" text and blue dots below it. But it doesn't proceed further from there.
Fastboot mode works fine though. I started having sudden bootloop, So i decided to reflash the KDZ using LGUp tool via download mode but to my surprise I can't get into Download mode beyond "Download mode" text screen.
Any help ?

I gave up on it, and left it over night. It booted into download mode next morning. So maybe just let it cool a bit. a couple of hours should do.

If you aren't too concerned about the data on the phone, you can go into recovery from Fastboot, and try reset the phone. Otherwise, I would recommend you check the hardware that everything is plugged in and connected correctly. When i replaced the screen on my OP3, i did not have problems but i made sure to check everything before i snapped it back together for concern of something like this happening. Worst case scenario, i think the recovery mode from fastboot option also has a way to allow USB access to your data.

LG G4 can't fastboot/reboot bootloader

Ola!
I'm playing with a LG G4-H815.
When using `adb reboot bootloader`, the phone just boot on normal mode.
When doing the Volume Up + Power button thing, I manage to land on Download Mode but nothing happens, `fastboot` does not detect the phone. And I get this popup:

Reset Factory doesn't work either. Does nothing but reboot the phone as if nothing happened.

Try connecting the device to a PC and selecting Fastboot on that menu. The screen should turn off and the device should be detected by the PC; then you can open a command prompt/terminal and type "fastboot devices" to check if the device is recognized. After that you can try "fastboot boot pathtorecovery.img" for try booting into recovery from the PC.
You may need to install both drivers and ADB/Fastboot, for that look on XDA.

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

Press and hold volume up + volume down + power button all at the same time until the phone turns off and powers back on. Once the phone starts to reboot, let all 3 buttons go at the same time. That should do it.
Thank you, I tried this but didn't get any results.

After all these devices that Ive owned, the very same thing occurred when I was updating the S22U firmware using official SmartSwitch software from same PC for many years.
