Kernel panic/error ubifs CCR1016-12G r2 BBAA0B09ADA4/012/r2

This unit do not work. I have some “r1” that work nicely, this “r2” do not work.

Netinstalled without keep config with proper version, with 6.44.6 - 6.45.9 - 6.46.6 - 6.47

also try format nand from bios

updated bios for every version, the problem still present

Just netinstalled:

[admin@MikroTik] > export file=x
file operation error

winbox work but “file” do not work, i can not delete file, no copy, when reboot I lost all config, but I can still upgrade or downgrade boot or routeros.

RMA or driver kernel error?

Thanks
