Help! Stuck in the "Downloading..." screen when trying to root

[mechanicboy]

I tried to root my Verizon S3 so I could remove the Samsung bloatware and perhaps touchwiz but I haven't been able to and now my phone is stuck in the "Downloading..." screen after holding down volume down, home, and power button when the phone was off. I was using Odin3 to try and upload CF-Root-SGS3-v6.1.zip, then CF-Root-SGS3-v6.3.zip and CF-Root-SGS3-v6.4.zip and none of them worked. My phone says "SECURE CHECK FAIL : recovery"

Please help.
