Banana Pi BPI-R4 Ethernet ports died

Banana Pi Router design BPI-R4(MT7988)
1

I have an issue with my Banana Pi BPI-R4 board, RJ-45 ports suddenly stopped working. Also 2 of the green LEDs are on for some reason. Issue occurred after flashing openwrt back and forth for some time.

I tried several images, including the banana original ubuntu image which worked before - same leds, no link on any port.

I’m attaching the boot logs of openwrt and ubuntu. In both logs this sequence is present:

I believe this is a hardware issue now :(( Extremely disappointed, as I was finishing building my tuned openwrt image…

Maybe I can figure it out on my own?

Thanks!

You can try to power it down for one minute by unplugging the cable.

Are the LEDs on from the start?

This won’t help unfortunately.

Originally everything worked both on ubuntu and openwrt.

I tried booting from sd, nand, this issue persist across 4 different OS images (3 different openwrts and one official ubuntu), ethernet switch can’t calibrate during boot.

Leds are turning on during boot at the specified moment - after kernel tries to initialize ethernet switch. LEDs are only symptom of the issue, none of rj-45 ports works.
