spent a good few hours last night
As the bootloader was locked went on the HTCDev site and managed to get a unlock bin file then connected to device via fastboot and sent the command to unlock, and it looks like it did it, had to confirm on phone I wanted to unlock - so after a reboot still get the Locked message at top, so have deduced until I dont unlock the bootloader I am unable to flash a recovery to it in order to flash stock ROM
