I tried to upgrade my CRS125-24G-1S-1N from 6.5 to 6.7. The upgrade failed and now it does not recognize any of the network interfaces. I can log into the serial interface, and it looks like everything was upgraded correctly, but doing a "/interface print" times out.

It can't find the network card to do a netinstall. It also will not recognize the SFP interface.

Here's the error that shows up during boot (Looks like in between the two beeps):
I tried doing a firmware upgrade as well to no avail. Any help would be appreciated!

Netinstall with RouterOS v6.7 can fix this. Press Reset button before connecting power to CRS125 and hold the button during boot process until "USR" LED stops blinking.
Check Serial console output while trying to connect to Netinstall PC to see if there are any errors.

Again, Netinstall doesn't work. It can't get TFTP because it can't detect the network interfaces.

I did find that resetting the board to defaults fixes it temporarily, but any time we try to install packages or upgrade routerOS, it does the same thing again, and has to be reset to defaults once more. That's pretty annoying in that we can't upgrade or install anything on it remotely. We'll have to physically hook up a serial port to it and reset it every time we need to make changes.

This issue is produced by setting ether1-gateway master-port=ether2-master-local in both RouterOS versions too. After reboot no eternet interfaces is visible. May be bad comunication with switch chip in this configuration.

please... would it be possible to provide a real, usable recovery procedure which does not require on-site button-pushing?
your higher end devices all have serial consoles.

i can understand, there must be a way to live with boxes w/o serial console. the button-pressing is accepted there.

but with a device located at the customer premises, and with tools you normally provide for troubleshooting (like
wireless spectrum scan, ethernet cable test) which basically reduce the on-field troubleshooting to minimum,
it's a real shame, that the failsafe procedures did not evolved in any way.

we have OOB devices on the bigger sites, though in case of issues like this we can't do nothing.
at least a cli instructable tftp client would do the trick.

you can look into partitions and what features of recovery they do provide.

I have the same issue, I tested upgrading from v6.4+ to 6.5+, in all cases the device is pretty much unusable.

I am facing the same problem, i had the (bad) idea to downgrade from 6.10 to 5.26, I am now facing a device without any network ports except wlan, wich is not configured.
Conecting winbox-computer to crs125 does not find each other, same at trying netinstall.
Is there a trick to unbrick this state?
Manu

Can you connect with serial device?

I tried, but realised now, my cable did not work. So i can not say if I had during this state.
I was able to recover ver. 6.10 with netboot and reset button.
