Hi Guys,
I also had a long time to try flash this WiFI-W6B. My solution is to unsolder and lift up pin 11 of unmarked chip (see yellow route on screen above). This route is connected to U0RXD (pin 25) of ESP8285 and probably blocking UART exchange.
Also don’t forget about GPIO0.
Good luck all.<\/p>\n<\/blockquote>\n\n\n\n

In this PCB we can see a different orientation of unmarked chip. After tracing I make sure that pin 5 (not 11 as earlier!) is connected to pin 25 (U0RXD) of ESP8285. When I applied the previous method and lift up pin 5 of unmarked chip, flashing was started.<\/p>\n<\/blockquote>\n\n\n\n
