So I got an old HTV One (M8) and I wanted to try installing a different OS. The problem is: I cant unlock the bootloader without an account at htcdev but their e-mail service seems unavailable. If I register with an e-mail adress the e-mail never arrives. If I try to register again it says: email allready taken. Can anyone help me out who has allready a htcdev account?
