Can not update software to 9.0.2. Gives a error message

Hi! Restart your device and try again.

Try to reset your device. This won't delete your data stored on this device.

• Press and hold the Sleep/Wake button
• Press and hold on the Home button
• Keep holding both buttons until the display turns off and back on with Apple logo on it.

Alternatively, you may go to Settings - General - Reset - Reset All Settings

After that, try updating your device once again.

I am having the same issue.

I tried the suggested hard reset and also doing the Reset All Settings function.

It still gives me that same error: “Unable to check for update"
