So, I bought a Nexus 4 in September last year. It is less than a year old, so I believe it is still under warranty. There was in issue where the display got messed up and displays lines over everything. I talked to a Koodo representative, who told me that it would be covered by the warranty. I haven't had a chance to bring it in, but in the meantime, would it be voiding the warranty to flash Cyanogenmod onto it?
