How do I restore a deleted file from my zoom H4n

I have a zoom H4n. Can you include a photo of your screen? What are you trying to do when it freezes?

open up the battery door. Make sure that the switch it is not set to "stamina mode". This disables many main menu options

There is a realtek app for sound cards that will do that and karaoke, it comes on many laptops and desktops. Some cmedia cards use this same app with their driver. Search for and install it without the drivers and it works on lots of hardware. Not sure if it will work on that zoom but, I would definitely give it a try. I have used it on several systems including the one I am using at them moment. I have a copy of it but I don't have a link to it, though. It's called realtek HD audio manager, and has tabs that has effects, open tab and on the right top corner has karaoke voice removal and choice of key.

If the menu button on your Zoom H4n recorder is not selecting or responding when pressed, it could be due to a few different reasons:

1. The button is physically damaged or stuck: Check the button to make sure it is not stuck or physically damaged. Sometimes dirt or debris can accumulate around the button and prevent it from working properly.
2. The firmware needs to be updated: If the Zoom H4n recorder has not been updated recently, it's possible that the firmware needs to be updated. This can be done by connecting the recorder to a computer and downloading the latest firmware from the Zoom website.
3. The recorder needs to be reset: If the menu button is still not responding, you can try resetting the recorder to its factory settings. This can be done by holding down the "Menu" button and the "Track" button at the same time until the message "Init All" appears on the screen. Then, press the "Record" button to confirm the reset.

If none of these solutions work, it's possible that there is a hardware issue with the recorder and it may need to be repaired or replaced.

You can go to service provider.

What I figured out - simple. Plug your usb cable all the way in. That's it. Did I guess it? ;)
