Okay.. I tried to install this and my battery went flat in the middle of extracting the downloaded image. Now I cannot re-download the image since it ways I already have it downloaded but it cannot extract it due "unkown error". When I'm trying to delete the "debian-m5-v3d.img.ext2.lzma" file from MyDocs it gives me "Read-only file system" -error even if I'm running the rm-command with root priveledges.

Any ideas how I can remove the file from MyDocs and then re-download the package?

Edit: Got it working now. Rebooted the phone and connected it in USB-mode to PC and then I could delete the file in Windows file manager.
