Hi all ! And thank you for this post, intended to fight obsolescence ;)
I have a DS412+. I've managed to transition it to DS713 through ssh, but got stuck at the update to 7.0.1, and I believed it was because I was in 6.2.4.95556 update 7. So I followed another tutorial to downgrade it, wich told me to delete the etc.defaults/VERSION file by rm command in ssh. Once rebooted I could start the process of installing a pat file, but it crashed, and after the next reboot, nothing, blue blink of death. So I then tried everything, mounting the USBDOM to my computer (which works perfectly in usb2), restored it file by file, then the entire .img - I made a backup earlier), nothing. Even tried to connect to the serial pins with a special TTL adapter, nothing, no output from terminal or putty. Tried with new disks, zero disks, reset button, every combo possible...
So my questions are : is there a way to restore this VERSION file ? And... Is it time to buy a new one ?
Thank you very much !
