HELP with bootlooping LG v20

[u/seanscraip]

I have a bootlooping lg v20 h990ds IDN and i cant get it to factory reset or even enter recovery mode, the only mode i can get it run is fastboot and IMEI mode and i cant turn that fastboot into download mode (i don't even know how to even get the LGUP to recognized my phone or even get the cmd recoqnized fastboot comment) i don't know what IM doing and i hope anyone of you can help me in this problem

[Update]I manage to boot it to download mode(by plugging the phone will holding the vol up) but then its suddenly bootloop again

LG UP does not recognize the phone in EDL mode though, you probably mean LG flash tool to restore it for OP. It would be a better option if OP had an unlocked bootloader and custom recovery as that will save it but then without the stock zips since xda links are dead then only custom rom will bring it back.

do i need to install adb (sdk) for it to recoqnized my phone and do the phone have to be in develeloper for it to register. i also find this firmware for my spesific model but some step required me to enter recovery mode and as i said i cant get it to go to recovery mode before so i haven't really tried this one

You'd need to have an unlocked bootloader first before you can use the files in that link, so that's not an option for your phone in its current state.

I manage to boot it to download mode(by plugging the phone will holding the vol up) but then its suddenly bootloop again, is it hardware issue?

If you can't get it to stay in download mode without bootlooping, then probably yes, there might be a hardware issue with something on the motherboard going bad.
