When you do this after you plug in a cable, Press test (setup menu) and save the serial.log.
Just saw your latest. Congratulations! You shouldn’t need to re-flash, use the menus to update to the latest version.

Successfully retracting and extracting now. Going to proceed to the rest of the calibration. But all signs are positive @ian_ab @bar @RandomDave Thanks for your help in troubleshooting.

Let us know how it goes. Nice bit of fault finding and fixing. Gives us another thing to consider when chasing problems. Have you got photos of what you fixed?
The PW546A IC in the picture above has solder bridging across the pins. It was noticeable on the left side under a microscope, though on the right side it is visible even to the naked eye in that image. A bit of desoldering flux at 850 cleaned it up nicely.
I also had to replace the R20 SMD component.

Woah! What a fix! Way to go above and beyond in tracking down what was going on there

Fun stuff for sure, and if it happens to other users. We should know what to do now. Thanks again for your guy’s help
Hi guys,
Sorry to revive this one, I am having a similar issue after upgrading the board and encoders to 4.1 as the RJ45 were getting disconnected.

Where did those grey encoder wires come from? Are they custom made? That seems like the first thing that I would investigate.
I don’t have the pinouts on hand right now, but I can grab a picture tomorrow

they are from a local RC store, when I purchase the upgrade it was only the board and 5 encoders that came in

Those do look quite like ones I found on Amazon when I was finding some.
Are they straight cables (the connectors are at 180 degrees, but each lead goes straight, so pin 1 on the first connector goes to pin 5 on the other)?
They need to be pin 1 to pin 1 (I can’t remember if that is a crossover cable or that means something slightly different)
If so, it is possible to carefully pop each pin out and rewire them to make them work.

Thank you Bar and Dave, I had a look this morning and they are straight cables, each cable goes to the opposite pin. I’ll try to rearrange with the pinout diagram this weekend
That sounds like the issue for sure. I can send you the right ones for free. Will you DM me your order number so I can investigate why they didn’t come in the box?
thank you @bar, when I purchased it the kit was sold out and I purchase the board and encoders separate
