Accidentally tried to flash rom after doing saferoot (not possible)
Can you enter into recovery of download mode? 

As your phone is booting up, (right after the phone vibrates), press and hold on Volume Up and Home to enter recovery. Volume Down and Home to enter Download. 

If you can enter either of these, there may still be some hope by flashing back your stock Verizon rom through Odin. 

Otherwise, you will need to send it in for servicing.
