Relocked bootloader + bad modelid

I've recently purchased a CDMA + GSM compatible verizon M8 which I am using on T-mobile. Right off the bat I rooted, s-off with sunshine, intalled TWRP and Ive been running viper m8
I have attempted to flash new firmware and change my model id per scotts toutorial, but this is the model id that comes up: ������������ modelid: tpms:tpms:-:ukonoto

Also, my bootloader says "relocked" and I cannot access recovery (twrp) even though i reinstalled it.

Any help would be great!!
