Hacking Question help, cant inject payload, getting no backend available error

[freedom099]

Hi guys

im very new to python and custom firmware

i managed to put my switch into RCM
I plugged it into my mac
I downloaded the payloads
and when i run the 'sudo python3 ./fusee-launcher.py ./fusee-test.bin' command

I get this

File "./fusee-launcher.py", line 593, in <module>

switch = RCMHax(wait_for_device=arguments.wait, vid=arguments.vid,

File "./fusee-launcher.py", line 466, in __init__

self.dev = self._find_device(vid, pid)

File "./fusee-launcher.py", line 496, in _find_device

return self.backend.find_device(vid, pid)

File "./fusee-launcher.py", line 135, in find_device

self.dev = usb.core.find(idVendor=vid, idProduct=pid)

File "/Library/Frameworks/Python.framework/Versions/3.8/lib/python3.8/site-packages/usb/core.py", line 1263, in find

raise NoBackendError('No backend available')

usb.core.NoBackendError: No backend available


I dont know what to do, please help

bump?

when i plug the switch with micro usb into my mac it only charges it, no external disks pop up, is that an issue?

Just to make sure, your switch is in rcm?

how do i check it's in RCM?
I have a homemade jig in
I pressed the volume up button and on switch and it remained black

when it plugs into my mac the switch charges but in RCM mode i can't really check

but no usb pop up on the mac

perhaps python can't find the usb

Make sure your Switch is not patched. If it's not patched, enter RCM and get access to a Windows PC running TegraRcmGUI. It won't work virtually on a Mac. It has to be a real Windows PC. Inject the payload and profit. If you can't find a Windows PC, get access to a dongle like RCMLoader One, and try with that. You can also use a phone to inject a payload (not sure about I-Phones though).

Well, he can inject a payload using nxboot.

Wait is the charging icon popping on the switch or is it remaining black? It's possible that no USB pops on Mac, you should try nxboot.

Hello,
2 years to late, but if it can help someone :
I encountered the same issue on Ubuntu.
In my case I just had to install the missing packing python3-usb
(sudo apt install python3-usb)
Now works well
