Hi guys

I recently got my US T-Mobile HTC One M9, and I dropped it (I know). Now one part of the screen is messed up. I unlocked my bootloader and installed TWRP. If I want to return my phone to HTC for repair, will they accept the phone, since I unlocked the bootloader? Also, if I just relock the bootloader, will that be fine or should I wait for a RUU for the USA version since I saw only the Poland T-mobile RUU is released?

Thanks
