Continuing the discussion from HDD Replacement (Single Drive):
Great Job Fox_exe, thanks a lot, I did debrick my dead device following your instructions (tftp method)
I was trying to reproduce how I did break my device and it was because I ran an apt-get update; apt-get dist-upgrade that left packaging system completly broken, trying to repair with aptitude wroke havoc.
So I see that after resetting device and installing latest firmware from WD web interface, system is completely old-dated with no possible solution as apt-get upgrade will fail (and any attempt to solve it: apt-get -f install, etc) Indeed, just after latest firmware install, apt-update will complain about missing keys, this one is easily solved with: apt-key adv
Regards.
PD: I miss WD providing the recovery images instead of one volunteer hosting them in google-drive , thanks again Fox_exe for it
