Hello Pickles,
thank you for your help, and sorry for not providing enough information in the first place.
Cases when it stopped responding (led goes out too)
1: Working on a payload txt and trying to safe.
2: Copying data from the library into the Switch1 folder.
3: Connected via putty and copying a language file.
4: Bunny is idle and doing nothing, when I finished reading GitHub and wanted to work with it I found the Folder in Explorer grayed out with no space used and only a " fat32" remark, and the Led off.
Those are the situations the bunny fainted on me. while case 3 only happened 1 time so far, case 1 and 2 seem to happen on a regular basis.
Also sorry for my bad English, sadly its not my native language.
