I'm sorry for assuming you haven't read it, but your badge clearly says you are a new contributor and based on your statement "there wasn't a search bar for questions" in the first version of your question, I assumed you haven't yet found the [help page about searching](https://bricks.stackexchange.com/help/searching).

I did find the tour in my inbox, but I never found the help page. Hopefully, things are clear now.

# Lego Mindstorms Software: "Error code: 4"

(Asked by: username_0 on 2020-04-01)

After updating my EV3 Brick's firmware from V1.09E to V1.10E and reinstalling the **Teacher Edition** of the Lego Mindstorms EV3 software (even though I'm not a teacher), I decided to recover my Brick's files by downloading them from my Windows 10.

But when I downloaded one of the projects, the software froze for about 8 seconds, then gave the following errors. But I already know what they mean, so you don't have to worry about this. It looked like this:
