Got also the issue that key_info is not flashable and got told that the partition doesn't exist.
How can I fix this?
I got the same issue when I tried to flash 1450.zip over stock BETA 3.
I just wanted to get this working somehow without the stock rom, So I flashed TWRP, reformatted my /data, repaired my /system and any other partitions that I could 'repair' through TWRP, did a wipe of dalvik and cache, and then downloaded and flashed the latest OmniROM. Thankfully it worked.
