I've just received a PW3 (G090G1) today and it's on FW 5.9.7 so I gather that the only way to JB is to gain serial access.
I have looked around the site and after seeing this post decided I would attempt the method with pins (partly) detailed here.

I've ordered the FT232RL-FTDI-USB-3-3V-5-5V-to-TTL-Serial-Adapter-Module-for-Arduino-Mini-Port it mentions, various cables, pins, clips and connectors for just over £10 and one of these

Some of the instructions I've found seem to mention only connecting to the 3 serial pins, namely here

Is this because the TTL-232RG-VREG1V8-WE USB TTL Serial Cable supply's it's own power from the USB ?
And in other instructions

a fourth wire connect from TP1706 to V and a ground other than the next to RX & TX on the serial pinouts is used.
I've read elsewhere that TP1706 supplies 1.8v so do I even need the AMS1117.
Or is it the case that with the FT232RL I bought the power is going to come from the USB cable And I just need to 'step it down' with the same wiring as shown in the first post I mentioned
A tad confused. Sorry if this is a dumb post but I'm willing to give it a go but not an electronics expert !
Actually writing this has got things clearer in my head I think ?
I think I can ignore TP1706 ?
Posting anyway in case anyone has advice or can tell me where I'm horribly wrong. It will be a good few days until the parts arrive
