Well to tell, the router has revived.
I so understand, what there is no sense to update repeatedly 4.1?
ok, i tryBecause you select the firmware upgrade option in RouterBOOT menu.invalid upgrade file id
Select boot from ethernet after you start the netinstall, and NOT the firmware upgrade.
Reboot the router and it will boot up, and waiting for installation server...
And how? The network is inaccessible at a router.reinstall RouterOS v4.1 via the 4.0 Netinstall from our site.
