Hardware Switch charges and docks fine but not detected by PC in RCM mode

[FiddyOnFiddy]

Alright I really need some help with this as I'm absolutely lost now.

I have a switch here that I repaired by replacing the USB C as it had broken pins inside and the M92T36 as the console would only charge one way but not the other despite the usb c being installed correctly.

After this charging worked properly, it docks and displays image so all was good. Now this switch is possibly patched so I put it in RCM mode, which I have confirmed it is in by the fact it draws .04a and no switch logo appears when attempting to power up. But when connected to the PC it is not detected at all which led me to believe an issue with the USB Cs data pins but they're connected and working fine, also replaced the M92T36 a second time just in case but no joy.

Really hard pressed to track down where the issue may lie as everything else seems to work. The console is being sold on once I have it repaired so ideally I'd like this feature working as the console may be unpatched but the fact that it works fully otherwise means it's not necessary to have this working except I'd really like to figure this out.


Any help is greatly appreciated

Thanks.

EDIT: Upon further testing it appears in RCM mode there is no power going to the data pins. Tested against one that is detected and it has the 3.3vs across pin 6 on the top row.

What part of the board is responsible for powering data pins, particularly during RCM mode. Not too sure how those circuits work.

Got a similar issue on another switch except it charges one way and the other way takes about 15 seconds to kick in, or if you take it out of sleep by pressing the power button it then detects charging both ways but if the screen is off it takes a while so I reckon it's a similar part of the circuit.

Drivers are all good as when I put my own switch in or another one that works completely, it is immediately detected by TegraRCM

Sure you are in RCM? Tried a Payload injector? Tried another USB Cable or even another USB Port?

did you ever fix this issue.

I have similar o a unpatched switch. well two of them.
it's probably my trace repair under the usb c port , but docks and charging both sides of port.

replace now twice now aswell
