Mikrotik RouterBoard CRS125-24G-1S-2HnD-IN: what image to boot?

Hi all,

I'm new in this forum so let me to introduce myself: I'm Rubén from Spain, I'm user of Gnu/Linux since a lot of years and I have installed OpenWRT in several devices.

Great work with OpenWRT/Lede, thanks so much you all, developers, for it.

Now, I explain my question: I have a Mikrotik CRS125-24G-1S-2HnD-IN and I want to boot with OpenWRT/Lede it. My final quest is to mount mtdblock devices (I lost my admin password and I want to use the "old trick" password delete on /etc/shadow).

I test several ar71xx images (elf binary) and I can't boot, It stops in serial module.

A old Barrier Breaker OpenWRT image starts Mikrotik but don't recognize mtdblocks so I can't mount it.

I read on wiki page there are some working points for this device but I can't encounter image.

I try openwrt-18.06.1-ar71xx-mikrotik-vmlinux.elf, openwrt-18.06.1-ar71xx-mikrotik-vmlinux-initramfs.elf and stable release without success. (

(Sorry, I can't add links due to two links limit to new users on the forum.)

Please, Can you indicate me what image is correct for this device?

Thanks so much, sorry for big post and bad english.

Best regards.

Salud y Revolución.
