RB951G-2HnD reboot loop

Hardware MikroTik hardware general
1

I’m new to Mikrotik routers, but I purchased a 951G under the assumption I could tinker and always netboot it back to health, since routerboot doesn’t get overwritten by anything I install.

So, I upgraded to 6.1, upgraded routerboot to latest (I think it was .06), saved my key, partitioned the NAND, copied my working setup to it, set failover from active to the backup and from the backup to netboot. I had to netboot after the partitioning, but I figured that was because the wrong partition was set to active, or something.

Then I compiled openwrt and used dhcp/tftp to flash it over. It did not work, but I didn’t expect much more than that.

I figured I was done for a bit and fired up netboot to get the router back up, after I saw that the failover did not work. Netboot did its thing and reported success, but the router is stuck on a reboot loop. I tried downgrading to 5.25, same result.

Basically, the ACT light comes on, stays on for about 10 seconds, then the router reboots.
I can get it to netboot and the process reports success every time, but the router will not work.

Was I wrong in my assumption that routerboot would always avert a brick?
Suggestions?

I always thought that if you can get into netinstall, it is not bricked… but maybe the openwrt tftp overwrote something that doesn’t get restored with netinstall.

I highly suggest you send a message to support@mikrotik.com and see if they have any suggestions

It doesn’t make sense, to me, that anything sent via tftp could do any damage that could not be undone, since the firmware isn’t touched by that.
I figured I’d post here before bothering support, in case someone has had similar trouble.

Thanks for the reply. I’ll send them an e-mail.

Hello everyone.
I read long ago and always find what I want, but for months I have a problem that has me desperate.

I have ten Hnd RB951UI-connected and since it launched, I have had many locks on reboot.

The problem is that without any reason, BRs are restarted again and again until you need to do reset.

I updated 3 times RouterBOOT and software, and restarted again.

Do not know what to do.

Sorry about the language, I'm Spanish.

Deputy sample configuration. They are all the same except the IP.

Im having the same problem. Just rebooting over and over again flashing all the interface lights, even after a hard reset.
Will try a NetInstall this evening.
