Dear Matthias:

Thank you for your advice.

Your mean is that nedd to write "txrx.bin",
before write "txrx_wbx_raw_eth_20100608.bin" ?

Your mean like this?
-----
$ sudo u2_flash_tool --dev=/dev/XXXX -t s/w txrx.bin -w
$ sudo u2_flash_tool --dev=/dev/sdd1 -t s/w xrx_wbx_raw_eth_20100608.bin -w

I'll try this tomorrow!

Before update, LED D and F is.
But after that only F.

Now I use gnuradio-3.2.2.
I think that I can use WBX on USRP2 when I use gnuradio-3.2.2.
But I need to use gnuradio-3.3 to use WBX on USRP1.
Right?

When I try this command, u2_flash_tool return error.
