Does this mean that without an additional license, I will not be able to restore the firmware to the version that was originally on the device? Or I can use sw_keys.txt with factory number to install any of the versions? Serial number 821644469A5DDP. Ship Date 2016-12-28. Warranty End Date 2018-01-27.
Is Answer: "A Software update to the same Version number but a higher revision is usually free. A upgrade to the next version number (example 2.x to 3.x) requires the codec to be in warranty or a valid service contract" from FAQ is no valid?
