Paz, I followed your procedure and downloaded the 5005-2080 FW from liteon. But: no luck..... :sad:
If I change the filename from "LNFB2080.DS1" to "LNEB2080.DS1", the 5001 recognizes a firmware-disc on bootup and says "FW-UP", but immediately stops and displays "FAIL".
From what I have read so far, upgrading a 5001 to a 5005 consists of 2 steps:
First: you will have to load a modified firmware for the 5001 that will allow it to recognize a 5005 FW at all.
Second: you can load the 5005 FW into 5001.
Unfortenately I forgot the URL where I read this.
It was something like: "liteondvdrecordermod".
Any ideas ? (Google finds nothing) ....
