Firmware Update Does Not Connect?

I have a V1 Konnected
Installed the CH340, and it recognizes the device.
The COM port settings are correct at 9600 baud
When I attempt to flash (tool v3.1), it just repeats a series of dots and underscores.


Is this thing toast? Or am I doing something wrong.

I have the exact same issue

 Same issue here.



Same issue here

Managed to upgrade 2 of 3 boards but stuck with the third

 Same problem, anyone get a solution?

I ended up ordering and flashing a new nodMCU wifi board off Amazon/worked.  Can get them for £10 or so in UK.  Not sure if another way or a problem with original board.
