Hi everyone, My QNAP was infected last September by the muhstik ransomware, luckily I regularly backup this NAS to another NAS and all my data was safe. I powered off the NAS and disconnected it from my network. Since then I found someone had written a decrypt tool which I tested and this worked perfectly and decrypted all my data. As a precaution I re-initialized my NAS, which should delete all data from the disks. This worked fine the NAS booted up OK. As a further step I tried to perform a firmware recovery just to make sure there was no trace of the ransomware left on the NAS. This is where I've got stuck and now my NAS will not boot. I downloaded the latest IMG file from here Code (Text): https://eu1.qnap.com/Storage/TS-X53/TS-X53_20191206-184.108.40.2066.zip I extracted the IMG file, renamed it to DOM.IMG and copied it to a bootable USB with "DamSmallLinux" The TS-453Pro only has an HDMI and USB ports on the back, no VGA. When I connect the NAS to a monitor, keyboard and bootable USB and boot the NAS there is no BIOS boot screen, just a logo made of squares saying "Starting". I tried several times but no American Megatrends BIOS screen appears. Once the NAS boots I then followed this link Code (Text): http://qnapsupport.net/teknik-destek/hddler-takili-degilken-bootingde-kalan-cihazlarin-duzeltilmesi/x86-cihazlar-icin-ts-509-809-x39-x59-firmware-reflash/ basically to copy the DOM.IMG from the USB to /dev/sdb/ and rebooted the NAS. Now the NAS does not boot and I get the following message on the monitor "Reboot and Select proper Boot device or Insert Boot Media in selected Boot device and press a key..." I have tried the bootable USB in all the slots and still I get the same message. Any advice would be greatly appreciated. Thanks in advance.
