HELP! T.T NANDTool works, but not Dumpflash

[JJ-L]

Hi all,

I am able to get my NANDTool to work all well. (connection should be correct)
But when I tried to use the dumpflash in linux, entering the command "python3 dumpflash.py -c i"
would return a bunch of messages, and saying that there's insufficient permission.
However, when i tried with "sudo", it just returned "Device not ready, aborting..."

I then tried it on windows environment, When first tried, it state the following:
"File "C:\Users\JJ\Desktop\dumpflash-master\dumpflash-master\dumpflash\flashdevice.py", line 38, in init
self.Ftdi.open(0x0403, 0x6010, interface = 1)
File "C:\Users\JJ\AppData\Local\Programs\Python\Python38\lib\site-packages\pyftdi-0.43.0-py3.8.egg\pyftdi\ftdi.py", line 466, in open
device = UsbTools.get_device(devdesc)
File "C:\Users\JJ\AppData\Local\Programs\Python\Python38\lib\site-packages\pyftdi-0.43.0-py3.8.egg\pyftdi\usbtools.py", line 178, in get_device
raise IOError('Device not found')
OSError: Device not found
Device not ready, aborting..."

I then used Zadig to apply libusb-win32 on the FT2232H drivers. Retried again, and got return with just "Device not ready, aborting...".

After rolling back the drivers, and tested on NANDTool again, it still works.

Where could I have possibly done wrong, please advise :(
