It seems that someone on the XDA forums had gotten in touch with OnePlus with regards to rooting or unlocking of the bootloader on the OnePlus 2, and according to the customer rep they spoke with, your warranty won’t be voided. This is pretty much the same deal with the OnePlus One so we guess it looks like OnePlus won’t be breaking tradition just yet.
However there is a slight catch to this. While your warranty won’t be voided instantly, the service center will have to determine if whatever modifications or tweaks you installed isn’t the cause of whatever issue your phone is experiencing at the moment. If it is, say you installed a bad ROM that caused your speakers to stop working, then you’re pretty much on your own.
In fact this is stated clearly on OnePlus’ website where under Warranty & Repairs it reads, “By accessing resources regularly unavailable to software, the process may damage your hardware during or after the procedure, which is not covered under warranty. In warranty handling, we will need to verify that any faulty behavior is unrelated to rooting / unlocking first.”
