While there are a few different ways to trigger FEL mode, they are not always equal. Some do low-level initialization (load Boot0 and Boot1), and some don't.
If you are going to use FEL mode to retrieve device information, you need a to pick a method of entering FEL mode that initializes Boot1.

Boot1 allows you to use UART, otherwise there is no response from the board I believe. It might be worth trying the button combination for entering boot1:

By holding a standard button
This is usually one of the standard tablet buttons, like the VOL+ key or something.
The following seems to work:
Press and hold the suspected or reported FEL key.
Press and hold the power key for about 2 seconds.
Release the power key, and press it at least 3 times immediately.
Boot1 is initialized using this method.
