PATCHED SWITCH, but stuck in RCM mode


device only pulls 0.43A, no shorts around either of the chips.
When I connected to a PC and started TegraRcmGUI, it was judged to be in RCM mode.
Press and hold the power button for 12 seconds to turn off the power, but press the power button again to switch to RCM mode again.

this switch has been patched and paylode cannot be act.

What other ways can it be repaired?

This switch is in AutoRCM mode, try to Payload Hekate and turn auto RCM off.

this switch has been patched and paylode cannot be act.

Did TegraRCM recognize the Switch direct without jig procedure?

The TegraRcmGUI recognized that it was in RCM mode when only the board was connected to the computer without connecting the battery.
No Power Button and No JoyCon. :cry:

So there might be a problem with the emmc. Maybe the emmc gets no power, a problem with the connector or the nand itself.

I would check the connector for the right voltages and diode mode values. The first with battery and pluged cable the second (diode mode measurement) without any powersupply.


Thanks diode map.

Most of the places that exceed the value.
Can you identify the location of the failure?

In diode mode it matters which way around the probes are placed. The red probe should be on ground. :wink:
