Hello !
I just got my latest IOIO board and have to upgrade the firmware. I have 
entered the bootloader mode, and Windows 10 is detecting the board as COM7. 
So the versions I get the following results:
D:\IOIODude>ioiodude --port=com7 versions
IOIO Bootloader detected.

Hardware version: SPRK0020
Bootloader version: IOIO0400
Platform version: IOIO0030

In the IOIOdude directory I have 
D:\IOIODude>dir
 Volume in drive D is Data1
 Volume Serial Number is 7092-F163

 Directory of D:\IOIODude

23.06.2016  06:47    <DIR>          .
23.06.2016  06:47    <DIR>          ..

               8 File(s)      1 673 183 bytes
               2 Dir(s)  491 300 593 664 bytes free

However when upgrading I get:
D:\IOIODude>ioiodude --port=com7  write App-IOIO0506.ioioapp
Comparing fingerprints...
Fingerprint mismatch.
Writing image...
Caught IOException. Exiting.###          ]

If I add the --force option the write process just hangs. So what is the 
problem ?  Do I have to upgrade the USB driver in W10 ? If I try to upgrade 
the driver using ioio.inf,
W10 says, that it is not digitally signed.
Has anybody managed to do this upgrade process using Windows 10 ?
Ytai, can you test this upgrade process in W10 and possibly update the 
documentation, if something is missing, because we do not have the previous 
windows-versions anymore.
Thanks for the great product, If I just could get it working  again !
