Updating sharp firmware

Updating the firmware on a Sharp BD-HP20U Blu-ray player using a USB stick and a Mac was not entirely straightforward for me.The process is a bit brittle, so I’m documenting it in the hopes that I (and others) won’t waste so much time dealing with it next time around.

After you download and unpack it you will have a file with a .

If my memory serves me, that is a 2007-2008 model and it's looking like Sharp hasn't released any firmware for that machine since 2014.

And I really can't see the need for the folks to write new firmware on a machine of that age.

Disk only seems able to do FAT32, so I had to drop into the shell and use assigns the label “FIRMWARE” to the new filesystem.

You can use any 1-11 character string that adheres to DOS file-naming rules instead of “FIRMWARE”.

Plug it into your Blu-ray player and follow the operating manual instructions for applying firmware updates.
