Hello;

While upgrading from 3.12 > 3.20 from within Winbox I issued a shutdown command.

When he RB150 reboot I get nothing. When I connect a serial cable I see....


RouterBOOT booter 2.14

RouterBoard miniROUTER

CPU frequency: 175 MHz
Memory size: 32 MB

Press any key within 2 seconds to enter setup..
loading kernel from nand... OK
setting up elf image... OK
jumping to kernel code
System halted.

I am not sure how to unhalt the system. Anyone else ever encounter this ?

try Netinstall with the same upgrade packages, it will revive it.

Edit: I see you are running a very old Bootloader (BIOS) version. After Netinstall has revived your routerboard, upgrade the bootloader too with the command "/system routerboard upgrade"
