Problem 2: Some of the hardware mainly require few non-free firmware files to operate on

Now to fix this error the first thing that you require is a PC with an active internet connection. But first, make a list of the missing firmware file names. For example, “rtlwifi/rtl8723befw.bin”. Now kindly do follow the steps written below:

  1. Firstly, open any web browser and then open the link given below
  2. OPEN: https://www.debian.org/distrib/packages#search_contents URL

  4. So, if the firmware been searched matches the search criteria, then you will most likely find a list of files. After this click on the link mentioned under packages and then you will get redirected to a package contents page

  7. Just repeat this step 2-3 times for each missing firmware file
  8. Now after this connect to the bootable USB containing the kali image of your device. Kindly make sure that your USB device is not written using the DD mode. If it is a DD mode then you will not able to copy the files across. Just browse the USB device via the file explorer and then navigate to F:\pool\non-free\
  9. After this, you may be able to see the subdirectories. After this you are required to go inside the subdirectory, just copy all the files from there and then paste it inside F:\firmware\. And if there are already some files in there then kindly replace them
  10. After the successful copying of all the files from F:\pool\non-free subdirectories then you also need to copy all the firmware files and then paste them in F:\firmware folder
