If my LG phone got stuck (as in, did not react to hard reset) in download mode and I had to pull the battery, should I skip attempting to stock flash?

I factory reset my LG k7 phone to help with battery and storage issues, but upon reboot, I found that it was glitching up at the setup screen and says the 'Setup Wizard isn't responding. Would you like to close or wait?" on a black screen. Due to this, I had planned to go ahead and stock flash it, as I was recommended to do. Before proceeding with this, I decided to test out putting my phone in the required download mode. But when I tried disconnect it, which, for my phone model, means giving it a forced reset, it didn't respond no matter how long i held the buttons, which left me to assume it was frozen. I then pulled the battery. So my question is: should I take this reaction to being put in download mode as a bad sign and skip the stock flash? If the phone were to freeze up like this during the flashing, it would cause an interruption and a likely bricking. What should I do?
