This has happened with two routers I have purchased this month.
The router came with 6.36.1 and I upgraded it to 6.38.5 which is the current version and uploaded dude.npk for this specific version. I upgraded by uploading specific packages to the router, not the routeros file. The packages I uploaded were
system
security
advanced-tools
dhcp
dude
I rebooted the router and it went completely dead. No startup beep, nothing. This is the second router I have faced this with and don’t see anyone else facing a similar issue yet. Could you tell me what I seem to be doing wrong?
