Step 4 in particular is important as Zadig won't default to libusbK. You have to manually scroll down to it.
- Get your Switch into RCM mode and plug it into your Windows PC. It should show up somewhere (like Device manager) as "APX"
- Download and run Zadig driver installer from https://zadig.akeo.ie/
- From the device list, choose APX (if it's not showing up in the list, go to Options menu and check List All Devices)
- For the driver type, cycle the arrows until you see libusbK (v3.0.7.0) in the text box (IMPORTANT!)
- Click the big Install Driver button. Device manager should now show "APX" under libusbK USB Devices tree item.
I have the exact same problem, installed Hekate, then AutoRCM, backed up the NAND. Rebooted the device and now no longer can be detected in RCM mode. I tried everything you mentioned, good detail by the way One unusual issue, when I plug/unplug the switch I get a Windows device sound, so I know Windows is detecting it on the usb port (tried different usb ports as well) but the libusbK USB Devices is not displayed in Device Manager. I was once... and I deleted the driver, but now it will not display. I have reinstalled the Driver from TegraRcmGUI_v2.4_portable many times. Tried holding the power button for 12+ seconds, it turns off. Tried many times to press the volume up and power button for 12+ seconds, the screen goes black, but the driver is not detected. This worked perfectly last night
Any suggestions? What I would like to do is manually install the driver using Zadig but the APX driver is NOT displayed!, after hitting "List All Devices" So I can't manually install it
I have, a number of times. Also each time I try installing the driver it states just before installing the driver "APX Device driver is missing. Do you want to install it now?" . This worked perfectly just last night so I assume it's a software issue. Could it be an issue with Hekate and AutoRCM?Did you try installing the driver from the gui itself? Settings > install driver.
Hum, I tried the Web Fusée Launcher in Chrome but it would say, No Usb Device Detected. I could try another computer. My phone is an IPhone. What about reinsilizing the Switch, do you think that would help?Not sure sounds like some sort of computer issue that I'm not smart enough to solve. Do you have another computer? If all else fails you could also get a type c to type c cable and do it through your android phone if you have one.
Yes, I have tried both the msi installed version of TegraRCM and the Portable version, both seem to have the same problem I think I will try a new cable as recommended. I also might try Web Fusée Launcher on a Chromebook.Why are you and the OP using TegraRCM Portable instead of TegraRCM GUI? Unless they're the same thing, that may be your issues. I just know mine doesn't say portable. It says TegraRCMGUI 2.4.
