Firmware 01.01.20 or RockBox?

it was asking for .bin file when I tried to install , do you know where can I get such a file?

It’s asking for the original firmware file which you can find here. Extract the .zip file and place the .bin file on your desktop (or other place you’ll remember where it is). Then tell Rockbox where is is (when it asks) so it can patch it with the bootloader during the installation.

In the event it won’t take the latest firmware version (which the RB developers may not have gotten to yet), use the previous 01.01.18 version here.
