SPH-L710T debrick image file needed for Virgin Mobile

Can someone please help me with an unbrick/debrick image file specifically for the Kitkat SPH-L710T Virgin Mobile model? I have tried using the Boost/Sprint images but they won't work. Knowing the boot loader was already unlocked on my GS3, I tried the EZ Unlock app just goofing around one day and never in my wildest dreams did I think an app of sorts would hard brick a phone. It's not like I tried flashing a custom ROM for a different carrier or phone model, I am pretty well experienced in flashing and rooting, not a pro at it but not a noob either. Brand new phone out of the box and I rooted it using a guide by Max Lee via YouTube and I did not wanna flash a ROM yet until I activated the phone but I never got the chance. I don't blame the DEVS of the EZ Unlock app, I blame myself. My phone was complete stock and I removed no bloatware, the only thing I did was rooted it then screwed it up bu using an app that I had no business using. PLEASE HELP!!:crying::crying::crying::crying::confused::c onfused::confused::confused:
