Since the Raspbmc community proved to be so helpful, here is how I tackled the issue.
One solution is to browse the "nightlies" and downgrade to the previous nightly build.
Long, detailed version:
- SSH into the Raspberry Pi
- switch to the upgrade folder:
- get previous nightly build:
wget -c http://mirrors.arizona.edu/raspbmc/downloads/bin/xbmc/nightlies/xbmc-rbp-<older_version>.tar.gz †
tar xzvf xbmc-rbp-<older_version>.tar.gz xbmc-rbp-<older_version> †
- destroy the
- point the
.xbmc-current symlink to the new folder:
ln -s /home/pi/.upgrade/xbmc-rbp-<older_version>/xbmc-bcm /home/pi/.xbmc-current †
- grant full access to the
chmod 777 /home/pi/.xbmc-current/xbmc-bin/
- reboot and check in Programs > Raspbmc Settings that it worked.
If anyone has a better / more elegant solution, please share.
