Hi, anyone has any issue with upgrade Mikrotik to latest firmware 6.42.6 from older firmware version?
I have already two RB433AH upgraded from old version 4.17 and 5.x and both of them are frozen after upgrade, ethernet is coming and going looks like they are rebooting in loop but no second beep and no luck to run them. Does anybody have similar issue or recommendation?
Thank you in advance for any suggestion.
Patrick
