Accidently flashed recovery over boot partion with flashify

HTC Desire 326s (Metro PCs) So I accidently flashed twrp over the boot partition with flashify I tried some tutorials now it wont let me reunlock the bootloader I've tried running the twrp from fastboot but it needs S-off now the phone only boots into the bootloader and RUU gets stuck at the green arrow in the circle when I use RUU I let it sit for an hour nothing happens and everytime RUU will say Error [155] I'm not sure what else to do now I'm still looking around for fixes but I cant seem to find much
