Default [Q]Bootloop, no recovery

Hi, my D802 is stuck in a bootloop, where it just shows the LG splashscreen and the custom ROM's boot animation, but it won't get past there.
Unable to get into recovery either. Phone screen just flashes and LG logo comes back up whenever I try the recovery combo (power + down then power + down). I can get into download mode but I can't seem to get adb to work, and then use [adb reboot recovery] to boot into recovery. Drivers all installed, and all are the latest. Recovery was working fine before this and it screwed up only after I flashed a custom ROM.

What am I doing wrong? My phone is now nothing but a paperweight since I can't get into the OS nor the recovery. Thanks.
