Hello,
I have upgraded RB150 minirouter to ver 4.17. I tried to get the (higher version 5.17 - mipsle version), however upon the reboot, it didn`t boot up.
I have turn of the power and after turning it on it was corrupted in nvram. I have done netinstall 4.17 and was capable to bring it back among the live ones 
, however it says that it has no key ?? 
Does this mean that i have to issue a new licence ?
Thanks in advance
