I used Flashify to backup my stock kernel, went to furnace kernel, and decided I didn't like it so I would go back to my stock kernel.
I used Flashify to go try and restore my stock, and it asked if I wanted to reboot. I said yes, so it tried to reboot, but now it won't boot.
Whenever I try to boot, it goes to the LG logo screen for a brief moment, and goes black. I can't get into download mode or recovery mode. I'm on D803. If anybody could help me, please do!
Update: Weirdly enough, I just tried booting again on a whim thinking nothing new was going to happen. However, I managed to boot into recovery this time. I restored my last nandroid, and all is well. I'll be weary using that restore kernel now though.
