You need to have a clockwork mod recovery that is built for this phone, or whatever phone you are using, in order to get it to flash. Without a custom recovery for the galaxy stellar, or at least a recovery that is sure to work for this phone (I think I heard about some S3 stuff that works for the stellar, like the root method I think you used) the recovery will not flash and your phone will not load until you reflash the stock recovery.
Do not flash any recoveries until you know they work for your phone (i.e. someone has tested them), or without a backup of your stock recovery.
Since you are both saying you're not devs and don't really know what you're doing (neither do I really) I would suggest not flashing any recoveries that have not been confirmed to work for the stellar. Yes, many people use CWM and TWRP but there is a custom build of those recoveries for every phone, they are not universal.
I'm really interested in this phone so I'm hoping some development starts. Without community support and development I don't think I would bother switching to Verizon to get this phone even though its free. I hate cell phone contracts...
