Hello Charles, All,

Your FS-iT4 is a first generation.
Mine is a second generation.
The firmware is sure for a second generation of FS-iT4.
The latest version is 1.02US 07-12-2013

Do you have contacted Flysky by mail ?

Do you have configured your FS-iT4 to "FS-iT4 emulator" in sub menu called "USB menu" ?

Does your FS-iT4 is it discovered by the update software on windows ?

Note: Until you click on the "update" button nothing happens.

Do you really need to update your device ?
If you want to be secure, don't update yours FS-iT4....

Regards,
Renaud
