I have read about problems with crossroads and later versions of Ros.
I'm currently running 3 boards on Ros 3.7.
2 are fine one is deaf I don't know if this is the problem or something else.
So I started to search and got this http://forum.mikrotik.com/viewtopic.php ... ds#p109449

in the post it says that there are poblems with Ros 3.6 and that 3.4 is advised.
The poster says he could only get 3.3 to load but thats the end of it.
Is this still the status ?
There is nothing in the changelog to indicate a fix nor is there any warning not to use anything above 3.4 on the download page for the crossroads...

I didn't want to ask before looking but I cant find an Archive for the older Ros's and I can't seem to find a procedure for downgrading the ros Apreciate a point in the right direction.
Cheers

I used a serial cable and netinstall to bring back a couple of bricked crossroads. I haven't tried 3.7 yet, I'm sticking with 3.3 right now.

An easy way to downgrade is using webbox.
