Question [Q] Rogers HTC ONE Stuck at RUU

I have a Rogers locked HTC One . My problem is that i have been running a Custom ROM with TWRP recovery with network lock & S-ON . Now that i have no option to remove the network lock on the custom ROM , i tried re locking bootloader in order to run RUU , i got Security Warning Still, when i tried running the RUU it is stuck at some point and progress bar is not moving . Now i have to return to stock in order to remove the network lock and i do not have any backup files when i rooted & installed the Custom ROM . Any help is appreciated . Regards
