RouteOS v7beta8 vs RB4011iGS+5HacQ2HnD-IN

With netinstall 6.47, routeros-7.0beta8-arm.npk installs fine but router fails to boot from flash, so always etherboots.

With netintall 7.0beta8, routeros-7.0beta8-arm.npk transfers fully but gives “_open() package failed: The system cannot find the path specified. (3)”.

I wonder if you have a faulty device? I have this same device and 6.47 works fine and I was able to upgrade 6.47 to 7.0beta8.

Sans WiFi?
