Bleeding Edge

If you want the possibility to also install pre-release software, you have to login to your device and write OS_PRERELEASES="true" into /data/etc/os.conf (which usually does not exists):

> ssh root@photos-xxxxxxxx
> echo 'OS_PRERELEASES="true"' >> /data/etc/os.conf

Now, also pre-releases are shown on the webui Update page.
