So is there no way to update the m8 from kit Kat to whatever New version without rooting the phone?

Settings scroll to bottom About phone at top software updates mines an open phone and updated it twice is that what your trying to do???

I want to update but thrs nothing in the about menu saying software update. It's missing from the about menu

Have you tried to do The update via PC suite.
If you have access of course.

you might have a network branded phone which they have no interest in supporting.
when you switch it on, do you have network logos ? do you have network/carrier based apps pre-installed on it ?

if the answer is yes, they could have removed the update feature from the menu themselves. as phem says, you can do it yourself with a laptop and flash official HTC firmware or you could root it and flash a custom rom

its not network branded as far as i know. m downloading htc sync now for the drivers. gonna try to update via the download link in the htc website which is about 1.6gb. any noob guides on how to do this proper?

look on the page that has the link, they shouldn't have a file without instructions on a company website. plus you'll need PC software to flash it.

you can search on xda forums you'll find untold things there.

Iv looked on xda aleady. My bootloader is locked but s off. I tried updating through pc using ruu but i keep getting a usb error 171 or smthng. It keeps disconnecting when restarting the phone to bootloader
