I successfully downgraded my iPad2,1 from 9.3.3 to 6.1.3 using those updated sources, the libimobiledevice MinGW Build (https://mega.nz/#!tt9zTB6D!S_uzQWfogZIuKzLACrFY56Rb_CTC0Oj0X1re6myU3T0) and odysseusOTA (http://dayt0n.github.io/odysseus/odysseus-0.999.zip) on Windows 10.
Wait a few seconds after pressing the start button.
On my iPad2 (Wifi only), I saw a vertical green line on the right of the screen.
After I put my iPad 2 (Wifi only) in sleep mode with libimobiledevice
idevicediagnostics sleep
and when the screen was black I used odysseusOTA with the correct 6.1.3 IPSW for my iPad2 (Wifi only)
idevicerestore -e iPad2,1_6.1.3_10B329_Restore.ipsw
** iPhone 4S and iPad 2 (Wifi + 3G) users should follow another guide because this one doesn't downgrade the baseband, so if you don't downgrade the baseband too, your phone or the cellular connection of your iPad 2 will not work.
