Hmmm.. I still godt the same error... I wonder if I should ask support, but I dont know if they can see that I have downgrade the firmware from DSM4? (mulitible times)

I believe it's not completly wiped the partition when you've tried to reset.

I think you'll have to back that data up on the device and remove the system partition(s).

The NAS can only work with data from the hard disk, and not the hardware it's self.

I belive your'r right that it did not wipe the partition fully, since the pictures (thumbnails) was at hand almost immediately...

This is bad, since backup of this device takes forever even if there is not much data on it.

EDIT: The covert procees og synoidex has started, maybe something good wil happen ?

Hi Jekyll

If you have time I would like a downgrade for DS111 DSM 4.0-2198 -> DSM 3.2-1955.

My DS is very unstable after upgrade.

I am running DSM 4.0-2198 on my DS212j but am having a problem with Time Machine backups. I would like to go back to the last stable version of 3.2 which I have on my install CD. I know that reversion to a previous DSM is not officially supported but what is the procedure for doing this? I am running two disks in a RAID 1 arrary and don't care if I have to reformat the drives.

As the DSM4.0 seems full of bugs, is there any way I would fallback to DSM3.2?

I could build you a downgrade patch, let me run it on one of my brick testing units and i'll get back to you.

What DS do u have?

Hello, Jekyll!

May I request for your help to downgrade my DS209+II from the latest DSM 4.0-2198 back to DSM 3.2-1955

Reason for this is that the 1GB DDR-2 667 RAM which was working in 3.2-1955 would no longer work in DSM 4.0 (from BETA to latest build).

I appreciate your help. Thanks!

[david_h]

Worked it out. Have successfully downgraded to 3.2 (1955) and my Time Machine backups work. I can only conclude there is a problem with DSM 4 and Time Machine.

David,

What process did you follow to downgrade? (I have the same model and wish to do the same).

Thanks..

[david_h]

Repairman,

Basically I just used the instructions that are in this thread.
I had the 3.2 (1944) .pat file on my installation cd. This was useful because you need to have the version details of a file older than what you want to update to (in my case I actually wanted to go to version 3.2 1955). I then used winzip to extract the VERSION file from 1944. To do this you just open the 1944 .pat file with winzip and only extract the one file. I saved it onto my desktop and then opened it in wordpad to print the contents. There is only a few lines of data in the file.

I then used a telnet session to connect to the diskstation from my win 7 pc (telnet not enabled by default on either the diskstation or windows 7 so you will need to turn this on in both places. When you log into the diskstation via the telnet session remember to login as root (not admin). Otherwise you won't have the correct privileges to edit the VERSION file.
I then used the vi editor to change the VERSION file details on the diskstation file (i.e. ./etc.defaults/VERSION). There are links in this thread to explain how to use the vi editor.
I then exited telnet and logged into the diskstation via the normal login screen (this time as admin). Go to control panel and run DSM update. It now thinks it is on version 3.2 1944. I chose the manual option and browsed to the 3.2 1955 .pat file (which I had also previously downloaded).

Diskstation will now update to 1955 and then reboot.

Thanks for your reply. My NAS is DS411+II.

Thanks for your reply. My NAS is DS411+II.

Can't make you one sadly, the CPU is an Intel Atom D525 Dualcore (2C/4T) 1.8GHz x86 Processor.

Since i don't have an X86 unit, I've no knowledge of modding it.
