While testing some configs in our lab someone managed to lock themselves out of a CRS125-25G-1S with a config that was somehow causing the device to lock up and freeze at boot, and would not accept any external connections and couldn’t login thorough the console either.
The usual procedure would be a reset, however normal reset didn’t work as it had the following parameters set:
/system routerboard settings set protected-routerboot=enabled reformat-hold-button=60s
This employee then proceeded to hold the reset button for 60s and triggered the reformat with the intent to netinstall, however after doing so when connected to the console cable the message below keeps appearing before it reboots, and there’s seemingly no way past this.
RouterBOOT booter 7.7
CRS125-24G-1S
CPU frequency: 600 MHz
Memory speed: 200 MHz
Memory size: 128 MiB
NAND size: 128 MiB
loading kernel... kernel not found or data is corrupted
In nearly 20 years I’ve never ran into a MT that I was unable to recover somehow. Any suggestions or is this one truly bricked with no option for recovery on account of protected-routerboot being enabled?
