I have a 4.27 (I think identical to the one below, but that's 4.23).

I'm confused about how to solder it exactly for a serial connection. Does TX have to be soldered to tp18 AND connected to the UART adapter somehow? Thanks.

Can't see what's under the tape!

What makes you think you need to do a serial recovery?

Have you tried this...

The WR741 uses the same hardware as the WR740...
