MIPS Image File

Thu Aug 25, 2022 7:51 pm

I'm looking for a MIPS image file that gets uploaded to Mikrotik devices during Netinstall. I'm trying to recover some devices that are glitching out with Netinstall, but that can have boot files uploaded to them with TFTPD and boot successfully.
So these devices refuse to install using Netinstall. I've tried using different versions, and 3 different operating systems (including Linux on Mikrotik's recommendation).

Netinstall in Linux picks up the devices (you can see the MAC addresses requesting, but the boot file doesn't get sent).
TFTPD works like a charm in uploading the other operating system image files, which are all elf. That's why I'm trying to get the image file for RouterOS.

The idea is to boot from the image file and then upload an NPK via Winbox or whatever other access platform will be available, and then reboot. I see Netinstall on Linux following the exact same process, in the log it first uploads package and then reboots.
Any ideas how I can get this file? I've been going back and forth with Mikrotik support for about a week now but things are getting desperate on this side.

YES!
Thank you so much.
I got the file extracted from the EXE as on r00t's site and the devices actually boot from the file. They have booted and stopped the boot loop but for some reason are not showing up anywhere on the network, so new problem to solve now.

UPDATE:
In case anyone needs this in the future.

I managed to extract the .elf file from the Netinstall .exe following the instructions here https://www.r00t.cz/Misc/MikrotikNetinstallFromCF.

The devices then booted up into the file using TFTPD. After that, they go into a 'searching for Netinstall server' mode and the only way forward is to connect a PC running Netinstall on the network. It then picks up the unit and uploads the firmware like a charm.
