Hi alecs123,
You seem to be having very strange problems. These are generally associated with a bad power supply, a bad image download, a bad SD Card flash or a bad SD card. Try eliminating potential problems. So check the SHA-256 checksums of your download and image. If you can use an alternative power supply, try it. You could also try removing dongles and USB devices to reduce power needs.
The -0 version works fine, but is very slow booting and it needs an internet connection. You should upgrade with git pull as soon as you can, this will upgrade it to patch level -9. The upgrade will fix lots of small problems, make booting faster and eliminate the need for an active internet connection. Don't forget to reboot after the git pull, this is very important.
