I've tried everything I can think of to get this to update but still no joy. Nothing shows up in Available updates but I too am still getting update failed error at start up. Just went into the search option of Addons in Settings and found Script- OpenElec Dev Update Enabled. Clicked on this and then on Launch which brought up a message URL Error. No builds were found for Amlogic.arm. http;//snapshots.openelec.tv Please check the URL. Clicked ok and it brings up another open elec menu with Official Snapshot Builds, Official Releases, Official Archive, DarkAngel2401 Dual Audio Builds.
Not really too sure how or if to proceed from here or if this helps at all?
