Dear Z64 users, Here is our official BIOS conversion files: http://minix.com.hk/downfile/Z64 BIOS.rar Instructions are included inside of the package: readme.txt Procedures, which are very simple: 1. Choose the folder you need to perform the BIOS change (Andriod to Windows [this one should be wanted by most of you], OR Windows to Android [very rare I believe]) 2. Copy all 4 files inside the selected folder to the root directory of your USB stick 3. During power up & boot up, hold down the F11 key on your keyboard 3. Choose "UEFI Shell" and hit enter to continue 4. BIOS re-flashing will then begin automatically 5. Re-flashing shall take a few minutes, PLEASE BE PATIENT! DO NOT DISCONNECT POWER DURING THE PROCESS, OR YOUR UNIT WILL BE BRICKED (KILLING THE BIOS WHICH YOU CAN'T RESCUE) Regards, Team MINIX.
