Need more info.

What version SuperSU? What version TWRP?

What "official update" file did you use? Was it an OTA or an RUU (list the exact file name)?

Also, do fastoboot getvar all, and post the results (delete IMEI and serial number before posting).

In addition to the fastboot output, I asked 4 questions, none of which you answered.

You have the M8 eye, not the "standard" M8. Far as I can tell (not many folks on xda have the "eye") you need a special version of TWRP for this version. You can try the right version TWRP, and flash SUperSU again, see if that helps. No idea if this version TWRP will work on not (can't personally vouch for it): https://forum.xda-developers.com/htc-one-m8/general/m8-eye-recovery-root-t3159648

Depending on what you did to the phone by flashing the wrong TWRP, it's hard to tell what the proper way to proceed.

I have a similar issue, but with a standard M8

£10 off ebay, so not expecting ,much (also means no known history) . 1 week old noob reading here and flashing phones

1) only boots to fastboot, and even does this when you leave it powered off, but charging.
2) select hboot, then to recovery, recovery doesn't run, just resets back to fastboot eventually, after screen goes white not black.
3) can partially speak to phone in fastbook and get versions ok (included below)
Getver all as below:
C:\Program Files (x86)\Minimal ADB and Fastboot>
(bootloader) version: 0.5
(bootloader) version-bootloader: 3.19.0.0000

(bootloader) gencheckpt: 0
all: Done!
finished. total time: 0.114s

4) never been able to boot to full o/s so not in developer mode, so cant get response in adb (and dont know how to use this anyway)
5) tried RUU.exe - fails with usb error after it tries to restart bootloader
6) tried ruu.zip from memory card - fails with partition update fail
7) tried fastboot recovery image 6.12.401.4 and it fails to write - error is 'remote:signature verify fail'
8) random google lead me to fastboot oem reboot RUU which does this:
E:\android tools>fastboot oem rebootRUU
...
(bootloader) Error: Command never completed
(bootloader) Error: Command timeout error
(bootloader) Error: Command completed with errors
(bootloader) Failed Reading block @ 786432

(bootloader) [SD_ERR] sd_write_sector: write sector failed (786432 256)
OKAY [ 10.052s]

9) htcdev unlock bootloader didnt work initially but has done now - is this a path i should try?

aim is to get a standard phone working again

Thanks

ok got my unlock token, seemed to flash it, but no status change/reaction on phone and rebooting still shows locked

E:\android tools>fastboot flash unlocktoken unlock_code.bin
sending 'unlocktoken' (0 KB)...
OKAY [ 0.125s]
writing 'unlocktoken'...
(bootloader) unlock token check successfully
OKAY [ -0.000s]

My responses to some of your points below, in red font:

(bootloader) version-main: 6.12.401.4

4) never been able to boot to full o/s so not in developer mode, so cant get response in adb (and dont know how to use this anyway) That is correct, you will not be able to use adb unless you can boot to OS or alternately TWRP custom recovery. So you are basically limited to fastboot in the current condition.
5) tried RUU.exe - fails with usb error after it tries to restart bootloader There isn't a valid exe format RUU for your version number (6.12.401.4) so you are probably using the wrong RUU. What is the version number or file name for the RUU.exe?
6) tried ruu.zip from memory card - fails with partition update fail Exactly what partition(s) is it failing to update? What is the version RUU you are using? The only valid one for your version would be the RUU.zip from here: https://forum.xda-developers.com/showpost.php?p=64926626&postcount=6
7) tried fastboot recovery image 6.12.401.4 and it fails to write - error is 'remote:signature verify fail' You can't flash an unsigned recovery image, unless the bootloader is unlocked. It also seems you are trying to flash stock recovery, and I don't see how that is going to help your current condition.

I think your best bet right now, is to try the correct RUU.zip which I linked above.
