Well, it depends. Usually, HTC will only check for the TAMPERED flag and the bootloader status. But sometimes, they may have a problem with the phone being S-OFF.
I S-ON'ed my phone before giving it for warranty repair.
Anyways, whether u will S-ON the phone or not, ill tell u how to S-ON.
Put the phone in fastboot mode. On ur PC, open command prompt and type:
fastboot oem writesecureflag 3
Then, do what the screen shows
HOWEVER, DO NOT S-ON UR PHONE IF HBOOT IS 1.55 OR ABOVE. THE TAMPERED LOGO WILL RE-APPEAR
