As mentioned, recently I sent my phone to HTC to replace the camera, I dont know how they broken my mainboard.and now the mainboard is replaced. Everytime I tried to unlock bootloader (old token or newly grapped token), it appears that UNLOCK TOKEN CHECK FAILED? So, am I really unable to root my phone anymore? Or is there any alternative way to root it? I saw a post mentioning that restore it with RUU will help, does it really do so?
