I was looking to see how much it would be to replace my HTC screen and it came up with htcs Web page and an article saying their are certain screens they will replace for free and I have one of the phones selected and I'm within all the requirements
If its a broken screen due to physical damage, it won't be replaced for free now. Anyways, to send it in you have to swnd it in through Koodo. So go to a Koodo store/kiosk to send it in. If HTC will replce your screen for free they will, otherwise you'll be called and given a nice quote on how much it would be to fix.
Also make sure you weren't looking at the US site. I doubt you'll get your screen replaced for free.
EDIT: Okay I just googled. First of all its a US program. Second of all its for the HTC M9 and any later phones created. Sorry, you will NOT get your screen replaced for free.
