I installed this beta firmware on the weekend. Here is my experience with it.
As above I experienced the same freeze up at about 80% and had to reboot into recovery and try again. This time I did a full factory reset prior to upgrading. After this the firmware upgrade went without a hitch.
Software booted up and added all new apps and features including Kodi 14.0. After configuring my Ethernet, wireless and Google information I immediately went into Kodi, installed "Backup" and restored my Gotham data into Kodi. This is where it started going south.
When I restored I did the usual restore "everything" and rebooted Kodi. It looked just like my old Gotham setup complete with custom backgrounds LAN paths, movies. Vertical menus, etc.
Everything looked good until I attempted to play any kind of video media or music. There was NO sound and the video source was jittering all over the screen.
I couldn't fix this for the life of me so I ended up going back into recovery and doing a data wipe again.
Upon reboot the firmware promptly reinstalled everything back to factory for me. This time I went into Kodi and created a path to video and played it. Worked perfectly.
Then i went back to "Backup" and reconfigured it to restore everything EXCEPT configuration files. Rebooted it and this time it had all my plugins but it still looked like stock Kodi. Everything played as it should so I manually restored Kodi back to the custom set-up that I use and it works excellently.
I think that the cross over from XBMC to KODI was a big upgrade and allot of changes were made that forced me into making new configurations. Now that this is out of the way it should be clear sailing for any new Kodi upgrades in the future (like the 14.1 upgrade coming soon).
I hope this helps some people do the upgrade. Believe me it is worth it to get to the new firmware and the new Kodi is streamlined and fast.
Happy flashing...
