My iPod had a dual sytem on it: the original firmware and Rockbox. I used Rockbox for playing music and the OG firmware when adding songs to the device.
A few days ago, it simply stopped playing songs. Anything I tried to play would skip and I couldn't update the database anymore. After a while, I decided to do a clean reinstall. I ran into more problems: iTunes wouldn't recognise it, Windows 10 and Windows 11 were unable to format it for some reason, so I had to use the AOMEI Partition Assistant to wipe everything and start fresh.
After doing that, iTunes no longer recognises the iPod. I managed to install Rockbox, but if I plug it on my computer it does nothing. If I press and hold menu+select to try and enter recovery mode, the screen goes dark and it doesn't show up on my PC.
Are there any ways to reinstall the original firmware on it besides iTunes?
