[Q] CF-Auto Root Endless Loop

I was trying to reflash Stock Galaxy S3 GT-I9300 stock ROM via Odin but it got stuck, had to restart phone and got the yellow triangle telling that firmware upgrade encountered an error and asked me to use Kies to recover it. I used Odin again to flash CF-Auto-Root-m0-m0xx-gti9300.tar.md5 instead as PDA, now after completion of the process, I get an endless loop of rebooting with the Red android background logo and CF message.

I'm unable to access Download mode nor recovery! Did I brick my phone?! :confused:

Any tips to recover this issue? Please help!
