CCR1036, ehterBoot problem

Hi,

I have MikroTik CCR1036-8G-2S+ device. After it was updated and rebooted, the device is stuck and in the display I get information “ehter boot”. That is all. I tried to unplug from electricity and start it again, several times, but nothing. I get the same information.
This MikroTik device have console port with RJ45 connector.
Can you help me please.
I have two console cable.
One cable have on one side RJ45 console connector and on other side it has com connector. But my PC doesn’t have com port.
Second console cable has RJ45 console connector on the both side and I have another MikroTik device (working properly) with RJ45 console port.
That is all I have.

The etherboot message is likely to mean that for whatever reason your device is waiting for netinstall:

You don’t need the serial/console cable for netinstall, though the procedure can be tricky, particularly if you are using windows 10 or 11, search on the forum, there are several threads with small tricks to have netinstall working under these operating systems, Linux is said to be more straightforward.

About the console cable, if you want to use it you need a USB to Serial adapter, it is usually a cable with a small dongle that adds a (virtual) COM port to the PC, , usually they are based on chips from FTDI or Prolific, they are inexpensive, but try to procure one from some reputable source as there are a lot of “fake” ones (no name/no brand) around that don’t work with the official drivers.

Hi, my friend.
Thank you for quick reply but I already tried this. Mikrotik device had version of RouterOS 6.47.nn and then I upgrade to v.7.15.1.
After that, the device was stuck, and I got on his display message: "ether boot’.
Than, I installed netinstall on Win11.
I did all necessery procedures to bring back this router in life, but nothing I could do.
For notice: I tried with netinstall version 7.15 and with version 6.47.

Any other sugestion? Please.

As said, netinstall can be very tricky to run, and sometimes it simply doesn’t work, but on a next reboot (or the next-next one) it does, do check (a couple ones, there are more):

A common trick - that sometimes helps - is to use a “dumb” switch between the PC and the Mikrotik device boot port, this - for whatever reasons - allows to etablish connection when a direct link doesn’t:

Hi to all of you for helping me to solve this problem.

After carefully reading the posts you provided me i was able to solve it. You were right, netinstall on windows sometimes is tricky.
