disc lite5 boot problem ( RBDisc-5nd )

Hello
A problem occurred while trying to reset the device.
First I pressed the reset button and then I applied the electrical power. I held it for about 30 seconds.
Now the power, usr, and wifi lights are constantly on.
Ethernet light is not on. The device is connected to the computer.

I turn off the electricity and turn it on again, no change.
I use the physical reset button and the lights are still on.

I think they call it routerboot mode, but I cannot do anything because the device does not receive IP in this mode.

If you want to netinstall your device then you need to setup your network parameters manually as described on Mikrotik wiki page

bu çözüm değil. cihazlar arasında lan bağlantısı kurulamıyor.

sadece fiziksel reset düğmesine uzun süre bastım ve sonuç resimdeki gibi. bu çok saçma.

MOD EDIT:
mahmet: ENGLISH only here please ?

translation using Google Translate:
This is not the solution. Unable to establish a LAN connection between devices.

I just pressed the physical reset button for a long time and the result is as in the picture. This is ridiculous.

If ETH not turns on, your device is broken.

Regards.
