Readynas ultra 4 operating system setup
Good day. I have Readynas Ultra 4 with xpenology installed Tell me, is it possible somehow to return the native operating system?
The server starts but does not boot. Nothing lights up on the display.
Can you get the reset button menu? This article applies except for the location of the reset button hole: How-do-I-access-the-boot-menu-on-my-ReadyNAS-Ultra-6-Ultra-6-Plus-Pro-6-Pro-Pioneer-or-Pro-Business-Edition .
After manipulating dd if=/dev/synobot.img of=/dev/sdu the old system is gone.
Is there any way to get my system back?
At the moment, having synology, I have access to ssh and can replace this download file.Your old system is gone. Recovery is impossible. That dd command overwrites an entire device with an image, including the "blank" space. You should have done a dd to save the current image before you overwrote it, but it sounds like you may have simply following a cookbook and didn't really know what this was doing.
Someone would have to be willing to do a dd of their image and share with you, and they may be reluctant to because it includes a file (named vpd) that defines the model and serial number. Now that ReadyCloud is dead (which relied on the serial number) and lack of other support from Netgear, maybe somebody would be willing. But your system would be a clone if theirs unless you get the vpd changed to be right for your unit. Previous moderators have helped other restore the vpd file, but I do not know if the current mods can or will.
Hi. I'm about to install DSM on my Readynas Ultra 6. Could you please advise how to backup my original image before overwriting it?
These are the commands that I will have to execute:
Now SSH into the NAS box and first of all unmount any USB devices:
#sudo umount /dev/sdu
First time you sudo it will ask for your password
#sudo umount /dev/sdu1
Next copy the synobot img file from /tmp to /dev
#sudo cp /tmp/synobot.img /dev
Next permanently mount the img file in the ReadyNas flash
#sudo dd if=/dev/synobot.img of=/dev/sduHowever, before doing so, I would feel much safer if I could backup an image of flash.
Thanks in advance.
