LG D858HK unable to get into download mode suddenly(not brick)

I wanted to flash the 20e kdz to my phone as 30a sucks. So I tried to boot my phone into download mode by pressing the vol + and plug it into the PC but it didn't work, I displayed the LG boot screen and show me the battery status. I am sure that the buttons on my phone is working well and it's not my first time to flash it. Can someone help me with this?

Don't you need to press the Vol+ button and not Vol- button before you plug it into the PC?

whoops, i mean vol +

dl mode

I know that u can enter download mode without a battery....isn't it holding down volume down and power button and plugging in a PC?

Hi!
Download mode can be entered by pressing HOME+VOL DOWN+POWER.
Not sure, though, if you would be allowed to go into Download mode without the battery. If it works, you would need to press the buttons (and keep them pressed) before you plug the USB cable. Buttons have to be pressed before power comes in.

What is the secret gesture to enter into Download/Recovery mode?

Hello,
Can someone give me the EXACT procedure to enter into Download and Recovery mode please?
If my tab (SM-T830) is switched off, and I switch it on by pressing Vol down + Power and I keep pressing both buttons, it will boot until the first splash screen (Samsung Galaxy Tab S4 Powered by Android) then after this screen, it will reboot..
If I release buttons during this splash screen, it boots up normally
I already succeeded to enter to download or recovery modes before but I have no idea how. I guess I must release 1 or 2 button at the point but when ?
Thanks

Hello,
Hopefully this will be helpful, the following procedure worked for me:
make sure the tab is off
plug the USB cable in your tab (but not in your computer)
hold down both volume buttons together
plug the USB cable in your computer
then the tab start (you may release the buttons) with a menu allowing you to choose (Vol +/-) between download mode and reboot.

It works perfectly, thank! That's a weird way to go to DL mode but it works!
And once I'm already in DL (and flashed a tar with Odin), do you know how I can restart directly to Recovery mode without rebooting to system?

This is really late, but go to recovery and select download mode.
Power off
Hold down all three buttons (power, vol down, vol up)
Once it vibrates let go of power and vol down, continue to hold vol up. Never fails.

Did this several times exactly the same way it's described and it fails every single time. Other way worked perfectly and easily on my first try.

A50 stuck in bootloop, can't go into recovery or anything else... need help

So I wanted to root my device, and i did the steps till i flashed twrp(unofficial one for a50), i was at this point: To get out of Download mode and Enter TWRP Recovery mode: Press and hold Volume Down + Power key, when screen blanks release Volume down only and quickly press Volume Up key. As the screen blanked out i also accidentaly let go of the power button... bootloop since... I can't do anything, can't use recovery, can't use download mode, cant connect to it with my pc using a cable. so either i wait till the battery dies or i find another solution...

1. Unplug USB cable from phone.
2. Hold down power button till it shuts off
3. When it's off, hold vol up + vol down & Press power
4. It should boot to download mode.
5. Load stock rom for your model (Check the variant to make sure)
6. All is back to normal again.
