Can't boot up
I think I did something stupid. I only had CM 10.2 on my phone, but had backups of ROMs from TWRP. I flashed Philz Recovery and then went to flash 10.2 and it failed. Now when I boot up it doesn't go past the LG screen then goes black. I can get into recovery, but don't have a rom I can flash as 10.2 isn't working and my TWRP backups don't work. I tried USB mass storage to put a ROM on it and it doesn't seem to mount.
