mAP lite no ethernet connection

Hi

after updating my mAP lite to the actual routerOS version the ethernet port stopped working.
Wireless is working but the ethernet port only auto negotiate on 10M full duplex without any traffic going trough the port.

i tried updating it to the actual beta and upgrading the routerboard firmware without luck.

it is the MK2 version with the metal shield betwen pcb and magnets.
i tried it without the magnets but without luck.

Netinstall is not showing the mAP lite even if i hold the reset key for a real long time.

what can i do to get it back to life?

Try this guide here: https://wiki.mikrotik.com/wiki/Manual:Netinstall

i know that guide.
But netinstall is not working as written in my starting post.

Sorry, most people find that netinstall “doesn’t work” but it’s usually because they didn’t follow every step

An alternative method to downgrade is to upload the npk for a previous version by pasting it into winbox then under the packages menu click “downgrade”

I have encountered the same issue on my mAP Lite: no ethernet link after upgrade (fw currently 6.45beta54). I don’t know if my mAP is MK1 or MK2; its serial number is 95DA098C61B4/839 and ethernet MAC is B8:69:F4:9D:95:F9.
It seems that this device is having ethernet auto negotiation issue. I have fixed it by logging in from Mikrotik Android app and setting the ethernet port to 100 Mbps full-duplex, autoneg. off. I did the same on the other end of the link (linux machine) of course: “ethtool -s enp5s0 speed 100 duplex full autoneg off”.
