The links have been renewed! First you need to download the modified bios then the stock one. Rename it to bios.bin and replace the one in the ‘bin’ directory. Execute the flash.cmd with administrator rights. After successfully flashing the bios, reboot the device and don’t worry the first boot might take longer than expected.
Then download the embedded controller firmware. Place both files into your C:\ directory. Go to the bios menu, save&exit, uefi shell, press esc, type “fs2:” and type “ite /u A13.bin” (Note: “fs2:” didn’t work for me. I successfully flashed using the “fs1:” command) For your information, I flashed the V11 stock bios dated 20.05.2016, then updated the embedded controller firmware. Thankfully I also got rid of the ugly cube logo.
