> You have only yourself to blame. Once you get the unlock code, your device is no longer covered by the Motorola warranty; in other words, please don't blame us if things go wrong, even if they appear unrelated to unlocking the bootloader.
In Australia they can revoke the "Motorola warranty" all they want. However, everything sold comes with a warranty that can't be revoked which entitles you to repair, replacement or refund for a reasonable time frame (yes it's intentionally open ended). You have to be using the item as intended, but if the company lets you unlock the device, then that's an intended use case. Even if you do "unlock a device" against a company's wishes, you're able to make warranty claims against the individual parts which are being used as intended. The company would have to demonstrate your tampering was responsible for the damage.
I'm aware the US does not have these same consumer rights, but can a company revoke a warranty?
