I uploaded the Version: 3.215 img firmware into Lucie now I am stuck

Router won’t boot. Have tried uboot procedure but the network cable only shows disconnected. I disabled wifi on my computer, and set the ethernet adapter ip to, subnet and default router but can not connect to the router.

Am I totally screwed here?

Good news! I flipped the switch on the side of the Beryl while I was in boot mode and the uboot page loaded up right away!

You need to hold the reset button for 5S to enter the uboot mode
