    Dear Z64 users,

    Here is our official BIOS conversion files:

    New MEGA link : https://mega.nz/#!RtBQRDjJ!E9vQSUfLrr9Jb_A77m_67zq9y5CfUaRcpDFctP4n5cE

    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!


    Team MINIX.

  2. You should also note that the USB must be in fat32 format in order to be readable by the UEFI shell! Cheers though for the official files glad to see you guys opened up to this after all!

    I updated my video with a link to the official files. For those who would like a visual walk through of this and how to install windows after this should help explain!

    If you want to convert from windows to android, please backup your windows license key before do that, because if you want to return to windows from android, maybe you will need to insert it.
    The windows key is inserted in the your installed Bios, I didnt test the new Bios from Ken (Thanks a lot for it :) ) but I think the key in BIOS will be empty.
    You can follow this tips from Bob Finless (http://www.freaktab.com/showthread.php?23160-Z64W-Backup-your-BIOS-Windows-Key) or use Magical Jelly Bean Keyfinder ( https://www.magicaljellybean.com/keyfinder/ ) to backup your stock license key.

    With "UEFI Shell" do you mean "UEFI : Built-in EFI Shell" or you imply first to select the usb drive?

    I simply shutdown the device from the power button. Then you will to install Windows. So after you have prepared the USB, put it in the minix. Now turn on it and press many times "DEL" button of your keyboard. Now you are in the BIOS. Check the Project Version, it should be changed from: "JCRDA 1.22 x64" to: "JCRDW 1.43". And if all it's ok, continue with the steps. ;)

    What is the tool you was using to make an usb boot from Win 8.1 ISO file?
  11. BartHD

    BartHD New Member

    Rufus. The same version of Gadget Friendly's videotutorial.

    Look at the difference:

    You can skip this selecting your USB below Boot Override. It will start the install process automatically. Don't have to go through the shell. [quote: WeK05]

    Great! But I suggest you to hide your Product ID in the last screenshot.

    When you go back to Android with the Flash Rescue - http://minixforum.com/threads/reflashing-the-z64-android-os-creating-rescue-disk.4735/, be prepared to wait for some time. It is a very slow process. It will look like it is frozen. Give it 20-30 min.

    if you can convert this z64a to windows, does anyone can dual boot the android and windows on this unit yet? thanks
  19. BartHD

    BartHD New Member

    Nope, because when you convert: "JCRDA 1.22 x64" to: "JCRDW 1.43", Android don't work anymore. And if you don't convert the bios, you can't install Windows 8.1 32 bit with Minix Drivers. You could install Windows 8.1 64bit and maybe a dual boot, but you haven't the right drivers.
