Hi all.
I’m new to the forum.
I have some routerboard mikrotik (rb751u-2hnd, rb912uag-2hpnd, …) with OpenWRT installed.
I want to go back to ROS but I can not do it… 
.
I tried with netinstall, but it doesn’t see the routerboard.
How can I do? My employer wants to do this.
Can we help me?
Thank’s.
Openwrt device pages usually describe the way back. Check them.
Hi jarda.
Sorry, but where can I check them?
I searched everywhere and found nothing…
Thank’s

Maybe it is not there for all devices, I am not sure. Maybe there is no way to get ROS back to routerboards, maybe you destroyed the license by re-flashing the storage, I do not know…
Did you the things on the bottom of this page?

If so, you can use tftp to put ROS back. Maybe.
I do not have any experience with this, I used Openwrt on Asuses and similar devices may years ago, my last Openwrt runs virtually for some testing purposes, an I have never installed openwrt to routerboards because the ROS is enough for all my needs. If you will not succeed using the information from the links I have provided, there nothing I can do for you more.
Good luck.
http://forum.mikrotik.com/t/change-boot-device-from-openwrt/84793/1 , NathanA mentioned rbcfg-utitlity, maybe that helps you to get your device boot to Netinstall?
Good morning.
Thanks to all.
I partially solved the problem…
.
Below is my solution:
- I installed the “rbcfg” package on routerboard rb912uag-2hpnd with openwrt installed.
- By terminal:
- root@OpenWrt:~#rbcfg set boot_protocol bootp
- root@OpenWrt:~#rbcfg set boot_device ethnand
- root@OpenWrt:~#rbcfg apply
- Open Netinstall and reboot routerboard. Now netinstall sees routerboard and you can install RouterOS.
I tried these steps on on rb751 and rb912 and the only problem is that it only works on rb912.
What is the problem with rb751 exactly? Not showing up in Netinstall?
Is there Reset-button in 751, did you try that?
