HTC ONE M8S locked bootloaded but recovery not working

Hi,
So I tried flashing a TWRP v2.7.0.2 to a HTC One M8s which on command line said was successful but when opening recovery the phone just powers off and does not load any recovery.
I then, stupidly relocked the bootloader (fastboot oem lock) and now have a bootloader saying ***RELOCKED***
I have tried a new unlockcode bin file but it wont matter as the recovery will not load when i select unlock bootloader.
Is there any other way to unlock the bootloader without having the recovery to run?
Please help!!!
Hi,
I had a similiar problem and used 'Squabbi's HTC One M8 Toolkit 2 2.5.0' to Re-flash TWRP twrp-3.2.3-0-m8.
Regards
Rob
I'm also having a similar issue when flashing twrp image successfully (bootloader unlocked) recovery loads the HTC white screen until the battery drains! I'm using Linux mint terminal. Could you point me towards squabbis toolkit to reflash? Tia
