[Update from DSM 6.1.4 to 6.2.3-25426]

Hi,

 

I've been running DSM 6.1.4-15217 Update 1 for 2 years now i think. Now i wish to update to DSM 6.2.3-25426.

 

DS3615xs 6.1 Jun's Mod V1.02b is the one i was using when installing from the beginning.

 

WHen looking for the critical updates o downloaded the latest one synology_bromolow_3615xs.pat (DSM 6.2.3-25426).

 

But when i in DMS manual try to update with this file it says: "The update you are applying is not compatible with this version of DSM"

 

Do i need to make a new bootable USB with  the latest update, or what could be wrong?

Thanks!

 Hello, everybody,

I already posted this in the german forum, but maybe it helps here too.

Unfortunately I also made the mistake to update from 6.2 to 6.2.1 and the system was no longer available. But after some trial and error I found a solution:

 I removed every single one of the hard disks of the raid system and connected them to the PC with a USB adapter. There I used the free partitioning tool Minitool Partition Wizzard to run a wipe on the 2.37GB partition (overwriting the partition with zeros). This is the system partition of the DSM.

Caution: You are not allowed to do anything on the other partitions and the installation order of the hard disks must also be observed.

Then I created a new 1.03 Bootloader USB stick and started the system. The Synology Finder found the DSM and didn't show any installation. I then manually installed the DSM_DS3617xs_23739.pat file.

After the first start the old volume was detected error free. All data was still there. Only the packages had to be reinstalled.

I think the solution will work with all versions.

 

I screwed it up with update. I tried this and it worked!! Thanks. Did not take more than 30min and all was back online 😁 Thanks alot!
