I have a KT3 with firmware 5.9.2.0.1. I would like to downgrade to version 5.8.0. But, whenever I copy the firmware, it gets deleted. I downloaded (just to try) the 5.13.3 version and examined it with a Hex editor. The first 4 characters are SP01, but in the 5.8.0 version, those are FB02.

Here is the question: can I downgrade changing the FB02 header into SP01?
