It´s working fine now, so I hope everyting is ok now. First boot was not successful, but after the second boot the NAS started to initialize. So that is the reason why you have two Systems on the DOM.Īfter doing all these copy things I restarted the TS-451 with the DOM in its original place. I think if a new image is being flashed and something goes wrong, the TS-451 tries to start from the third partition, which is left untouched. Sdb4: Extended Parititon (Size about 1 kB) Sdb3: System2 (Size about 240 MB) (Backup-System) Sdb2: System1 (Size about 240 MB) (marked as bootable) The partition structure on the DOM is as follows: Onto the DOM putting it in the correct partition (should be for example /dev/sdb2 and /dev/sdb3), you see the files when you plug the DOM into an USB-Port: You can then copy and overwrite the following files So I had to decrypt it first, you find the files needed for decrypting here:įollow the procedures described there using the ubuntu-Live-Image on your TS-451, first compile the *.c-Files using gcc, then decrypt the firmware image, it´s an *.tar.gz which you can unpack. This does not work because the Image-File is encrypted. I downloaded the actual 4.3.3-Firmware-Image from Qnap-Website and tried to flash it directly. So I started another approach, because I had the feeling, that the rudimental Recovery-Image might not have enough information. None was working, all had the same issues. I tried three different recovery-Images, which I all found on the Qnap-Wiki-Page: The DOM was not recognized when it stucks in its original place. IMPORTANT: I flashed the DOM using an Ubuntu-Live-Image from an USB-Stick, and - even more important - connected the DOM using an modified USB-Cable as described here: viewtopic.php?t=126426, because When I tried to start binaries, it claims that several librairies are missing. Login onto the console using a keyboard and an attached monitor, but there were only rudimental files readable. The Problem was that even when I flashed the 1.2.8-Recovery-Image using the routine described in Qnap-Wiki, it does not completeley boot up correct and was not found by QFinder. You for your very useful information, it almost lead to success in my case, but i had to implement some further steps to successfully revive my TS-451.
