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:

enter image description here

I continued to make attempts to download the project, but every single time, I got the same results. At last, I chose to postpone downloading that project and started to download a different one. And that's when things got strange. I got a bunch of errors like before, but some of them now had "Error code: 4". Unfortunately, I couldn't get a screenshot of the image at the time, but I do remember that all the program assets had this error while the programs themselves had "Error code: 0". And just like my other situation, no matter how many times I tried to download it, I still got the same results.

Fortunately I got rid of the problem by restarting my computer as well as the EV3 itself and then waiting a few hours before using either device again. Yet I still wonder, what is "Error code: 4"?

  • Alright, I've read the tour already, but I might as well read it a second time again Apr 2 '20 at 11:37
  • 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.

  • I did find the tour in my inbox, but I never found the help page. Hopefully, things are clear now. Apr 2 '20 at 11:53
