hard bricked verizon GS4 see image

so i rooted my phone yesterday finally after a long wait because it is a verizon sch-i545 on vrugof1. i was thankful that they got it figured out. unfortunately because of my ignorance i bricked the stupid thing custom romming on top of custom rom. the 2 following pix show what the 2 screens say : 1st on the phone it says "your device didn't start up successfully. Use verizon software repair assistant to repair..." and 2nd when trying that on my desktop the repair button is greyed out on said repair software because it doesnt recognize my phone anymore. tried many times to get into download mode but it wont go past the start up failed screen. please if someone had this happen before please help. thank in advance.
