[Q] I think I bricked my device. Assistance identifying my problem.

Hello everyone, I am running Lollipop on my Spring LG G3 and I am having a problem.

Recently I went to factory reset my phone, so I unrooted using SuperSu and proceeded to do so from settings and I ended up getting boot secure error. I tried to root using several scripts, manually go to download mode and it never continues, but stays on Firmware upgrade page.

I feel like I don't have a recovery? What should I do in this situation?
