you can only try.. moving the ROM to the ROOT of your sd card and rename in RHODIMG.nbh.. then see it it will go into bootloader manually and see the CDMA rom..
you may be F'd man.. GSM roms on CDMA usually brick it permanently..
also everything can be found here, since your going to have to try via SD card.. Verizon users have special instructions for the unlocking/flashing process

and why on earth would you DL the rom from some obscure site?? PPCG and XDA are the 2 most trusted places for sure.. id stick with them or VZWs oem site from now on when downloading Roms
