I've also got a Gen7 N54L and now did the update from 'update 7' to 'update 8' which was successful. All data on volumes still present. I tried earlier today on a Synology DS415+ to go from u7 to u8 and it didn't work and stayed on update 7. i'll try again tomorrow, so maybe just a bad download like above

posting to say I've installed on my N54L using this guide successfully using the AMD install option. New set of disks and new USB used for DSM 6 N54L previously was DSM 5.1. Completed install and ran update to get Update 7. I then plugged disk1 of 2 from my DSM 5.1 and the wizard was back at the beginning to build the DSM 6 OS. Moved disks around as obviously I had old disks in sata port 0/1 and now I'm back to my Update 7 OS. Storage manager now shows 'system partition failed' Added disk 2 and started a rebuild with the error clearing once completed and a "Good" healthy system. All data is still present from DSM 5.1 and the system shows 2 RAID groups which is what I planned for.
