How do I revert to an earlier version of the firmware?
I was asked by support to revert to an earlier version of the firmware but placing the zip file at the root of the storage and restarting does nothing. The update launcher does not sense anything. Is there a way to force update? I'm tempted to unlock the launcher and try some alrternative solutions but I think it affects warranty. Any suggestion is welcomed. I've lost 1.5 days already on doing this.
