Hi, svl7 I've already flashed the official 2.06 BIOS. However,when I was trying to flash the unlocked 2.06 bios modified by you,it says "the version of rom file isn't newer than version of bios". I've also Google this and found a possible solution(which is to unRAR the .exe file and modify platform.ini) ,but it didn't work. I'm wondering if there's a way to fix this? BTW, I've found a 2.07 bios of Y580/Y480 on a Chinese forum. It doesn't seem like an official rom, but some people have flashed this and had no problems.
