ZTE MF286d messed up install

Hello all

following the Wiki I've flashed the initramfs, ( I had to make about 10 restarts befor the Image was read from the tftp server ), then after removing stock partitions it came to sysupgrade. Sysupgrade -n was asking if I would keep the old settings or confirm for new settings. I've answered 'Y' for the new settings.

The process of installing the sysupgrade.bin did not finish successful, but sorry, I can't remember the error message anymore. I'm home only for a few hours on Weekends and I did the install last time I've been home.

When I switch on the Router the situation is now:

  • The Router does a full boot, I can login to OpenWRT via serial console.

  • None of the Ethernet Ports of the Router will give me an Echo ( no route to host )

  • I'm not able to reflash the initramfs again to start from scratch ( Uboot messed up?)

After a failed attemt to reflash the initramfs printenv is showing:
