No repl after upgrade to FW1.5.1.b1 with new FW updater tool (SOLVED)

[pmb_nl]

Hello,

I had a problem that the board wasn't accessible anymore via repl or visible via IP address after upgrade of the firmware. The LED was RED without blinking.

I solved the issue by redoing the same firmware upgrade but now without the high speed.
This worked. Perhaps interesting for others with the same issue.

Best regards,

Peter

Thank you for sharing. Btw, I've always uncheck High speed transfer option, because simply it never worked for me. ;)
