Hi,
long story short was upgrading both sxt and 951 but with the sxt connected via POE to the 951. The 951 upgraded first rebooted and the sxt went cucu…
So I went to netinstall. I see the RB, select the routeros-mipsbe (6.6) and click Install. It all seems to go fine but then the sxt reboots and reappears in netinstall. off course after ± 100 attempts with different software versions I already have the same problem on 951 as well. 
So the first thing that pops in my mind is: Is there a way to “turn net install mode off” ? I see some HW has this, but It’s not possible from console for sxt neither 951.
Anything I might be missing?
→ Messages from netinstall:
---->Partitioning and formatting
-----> Transfering; routeros-mipsbe-6.6
-------> blank
after this the router bips and reapears at the netinstall router/drivers list, like it is wating for software again.
any hints on how to proceed?
thanks
Tiago
