BL808 not work as normal after download firmware #4

I have received M1S Dock BL808 today , so excited. I followed instructions and was successful in downloading "hello_world.bin". However, after download, the M1S seems to be working nothing. When I tried "Open Uart", it said "Open /dev/ttyUSB1 fail".

How can I do to bring it back to work again? Thank you.

OK. I've managed to bring it back again by using TF2JTAG. Not sure how.
