Default [Q] m8 international Soff 4.4.3

Hello Folks,


I'm helping a friend to mod his m8 , he has installed 4.4.3 OTA I know I can unlock the bootloader via HTC dev then custom recovery and wakesauce to gain su acess, but can I use firewater to SOFF the phone after installing 4.4.3 OTA , I have read somewhere HTC patched stuff and firewater does not work on 4.4.3 devices?


Please advise ...
