didn't get as far as you did. Brought u p with 8.0; offer to update to 8.1. After some time to download, came up with error message it found issue and was collecting data to send and would reboot when complete. Went into loop rebooting, finding error gathering info and rebooting again. Extended push on power button and came up with message incompatible with 8.1, reloaded 8.0 Works OK but note all apps require 8.1. Any suggestions?
