HTC One M8 stuck in boot, even after factory reset

[AC Question]

Hi everyone! My HTC One m8 kept prompting that "google services have stopped working", so I restarted the phone to see if this would solve the issue. However, it would not boot afterwards and freezes at the HTC logo. Now, I tried several things, including cache wipe, data wipe and factory reset, but the phone still freezes at the HTC logo. Could anyone help me find a solution to this problem?

You could try reflashing the stock firmware.

Thank you for super fast reply! I made an account to reply to you. Could you help me in reflashing the firmware? I have googled of course, but the guides I see all assume the device can be booted, but mine can't of course. Could you point me in the right direction!
